1991
• A strange UFO appears in the skies over Japan and later lands, revealing people from the year 2204 who explain that the UFO is actually their time-traveling machine. Calling themselves the Futurians, Chuck Wilson, Grenchiko, and Emmy Kano announce to the Japanese government that they have come back in time to wipe out Godzilla from history due to the fact that in the near future Godzilla will destroy Japan with his nuclear might. At the same time, reporter Kenichiro Terasawa has a theory that two dinosaurs spotted on Lagos Island in 1944 during WWII became the first two Godzillas due to the nuclear testing on the island years later. Using that information, Emmy and an android by the name of M11 take Miki Saegusa, Terasawa, and Professor Mazaki back to Lagos Island during WWII using the Futurians' time-traveling shuttle KIDS. Their plan seems like to be a success since Godzilla is no longer in the Bering Sea, but the monster KING GHIDORAH II has appeared and is attacking Fukuoka. Wilson and Grenchiko created King Ghidorah II in order to replace Godzilla and use it to destroy all of Japan. After reprogramming M11, Emmy leaves the Mothership and tells Terasawa the truth. She explains that it's true that Godzilla does threaten to destroy all of Japan later on, but he will be stopped by G-Force, that she was sent with Wilson and Grenchiko as a spy in order to thwart whatever scheme they came up with to destroy Japan in order to stop it from becoming a corrupt superpower in 2204, and that King Ghidorah II was created from genetically modified Dorats with cells from both Grand King Ghidorah and King Ghidorah that would mutate into a new King Ghidorah when exposed to nuclear energy. As King Ghidorah II destroys Fukuoka and Kyushu, Miki explains that she doesn't sense the Godzillasaurus in the Bering Sea, but she does sense Godzilla heading towards Hokkaido, which is where King Ghidorah II is heading to. Emmy, Terasawa and M11 quickly head to the Mothership in order to stop Wilson and Grenchiko. Godzilla and King Ghidorah II meet on the shore of Hokkaido and begin battling, but with Wilson and Grenchiko controlling Ghidorah II, Godzilla is nearly defeated. When Emmy, Terasawa and M11 destroy the computer that controls King Ghidorah II, Godzilla finally gains the upper hand and defeats the monster, blasting off its middle head. When Ghidorah II tries to retreat, Godzilla blasts holes in its wings that causes it to fall into the ocean. Unfortunately, the computer's destruction causes the Mothership to automatically start a countdown to return to 2204. Emmy and the others escape inside KIDS in time and teleports the Mothership to Godzilla's location. Godzilla destroys the ship, killing both Wilson and Grenchiko. Godzilla then heads for Tokyo and begins destroying the city. As the Markalite Squadron battles him, Emmy comes up with a plan to go back to 2204, revive King Ghidorah II, and turn him into a cyborg in order to fight Godzilla in the present day. A few hours go by, but Godzilla's rampage is soon interrupted by the arrival of MECHA-KING GHIDORAH from the future. Godzilla and the cyborg Ghidorah battle, but in the end, Godzilla is subdued by the electrical shocks from the Godzilla Capture Cables and Machine Hand. While flying Godzilla out to sea, he damages Mecha-King Ghidorah enough to cause both kaiju to fall into the sea, but not before Emmy escapes in KIDS, returning to 2204. Godzilla soon escapes and heads off to hibernate.
• The remains of Mecha-King Ghidorah are salvaged. Work on Project MG and Project M begins.
1992
• A large meteorite crashes into the Ogasawara Trench, causing a chain reaction of environmental disasters to begin such as releasing Battra's egg into the sea from the glacier it was in and awakening Godzilla from his hibernation inside the trench. Battra's egg happens to wash up on the shore of an Indonesian island that was affected by the meteorite. Wanting to make sure the egg is safe and won't have a chance of hatching, the Shobijin and Fairy arrive to watch over it. Since the Marutomo company owns the island and has the Japanese government's backing, the company requests that the Environmental Planning Bureau sends a team to make sure the island isn't too badly damaged. The team, consisting of recently jailed thief Takuya Fujita, his ex-wife Masako Tezuka, and Marutomo representative Kenji Andoh, arrive on the island and discover Battra's egg. They are soon greeted by Moll and Lora, who explain the significance of Battra's egg and that it should be left alone in order to prevent it from hatching. Andoh contacts his boss, Marutomo's CEO Takeshi Tomokane, to tell him about this find. Seeing money in the egg as a tourist attraction, Tomokane has Andoh bring the egg back to Japan. When Andoh tells the Shobijin that Japan is a much safer place for the egg, they allow the team to take it as long as they come along. As soon as it's loaded onto a large transport ship, they set sail back to Japan. Unfortunately, Godzilla soon comes across the ship and goes to investigate the giant egg. Sensing danger, Battra hatches out of his egg and battles Godzilla. Their battle soon moves to the ocean floor near the Philippine Trench where their battle causes a massive deep-sea volcano to erupt. The two monsters disappear from sonar and are presumed dead. When the team returns to Japan, Andoh decides to steal the Shobijin to give to his boss in place of Battra's egg. While Takuya and Masako talk at dinner, Andoh traps Fairy Mothra in a butterfly net and runs off with Moll, Lora, and Fairy Mothra. Tomokane is happy with the Shobijin and Fairy Mothra and plans to use them as mascots for the Marutomo company. While no one is around, the Shobijin begin to sing for Mothra to hatch just in case Battra is still alive. On Infant Island, Mothra's egg hatches and she begins cocooning herself. The next morning, Fairy Mothra escapes from the butterfly net and frees the Shobijin. Suddenly, Mt. Fuji begins to erupt due to Godzilla emerging from it. At the same time, Battra emerges from the sea floor and transforms into his imago form. Both kaiju begin heading towards Yokohama. Mothra emerges from her cocoon on Infant Island and heads there, intercepting Battra. The two moths begin battling over the city until Godzilla arrives and attacks both of them. It is then that Mothra and Battra put aside their differences and start working together to fight Godzilla. They manage to defeat him and begin flying him out to sea. Unfortunately, Godzilla kills Battra, and Mothra is forced to drop them into the ocean. Before leaving, Mothra creates a temporary seal over the area in order to trap Godzilla there for a little while. After collecting Moll, Lora, and Fairy, Mothra returns to Infant Island.
• Due to Godzilla's appearance in the Philippines, G-Force's American branch begins working with the US military to create anti-Godzilla weapons of their own. Project CyberLizard, Project Arachnid and Project Mothra begin.
• It's around this time that Simeon insurrectionists arrive on Earth and infiltrate the US Military by disguising themselves as soldiers and important military figures, the most notable one being Colonel Cameron. The insurrectionists help with the construction of the anti-Godzilla weapons.
1993
• Project MG is completed after construction on MECHAGODZILLA 2 and the airship Garuda is completed. The two anti-Godzilla weapons are created thanks to reverse-engineering Futurian technology from the recovered remains of Mecha-King Ghidorah and the Simeon's own Mechagodzilla.
• A research team from the National Institute of Biotechnics is sent to Adonoa Island, an island that has been used as a dumping ground for radioactive waste, and discover a large nest with an egg larger than a human being inside it. As the humans take the egg back to their camp, it begins glowing red as the being inside sends out a telepathic danger call that is picked up by two different creatures. Unknowingly, the nest belongs to Rodan, who has lived on the island ever since the Monster Zero War. Seeing the egg as a "brother" of sorts, Rodan comes to the egg's rescue and begins attacking the human camp in order to retrieve it. Suddenly, Godzilla, who also responded to the egg's distress call, emerges from the ocean and begins attacking Rodan, thinking that the giant Pteranodon is threatening the egg's safety. While this goes on, the research team loads the egg in their helicopter and flies back to Japan. Godzilla defeats Rodan and begins following the egg's distress calls. The egg is brought to Kyoto for study at the National Institute of Biotechnics. It's believed to be a Pteranodon egg Rodan adopted, which brings Kazuma Aoki, G-Force's Rodan and Pteranodon enthusiast, to the lab. As he's being forced out by Azusa Gojo, he secretly swipes a piece of plant material that was on the egg in order to make up an excuse to go back into the lab and continue hitting on her. When Miki sees it, she senses something in it with her psychic abilities and convinces Kazuma to take it to the Psyionics Center. When the children there use their psychic powers on the plant sample, they are able to retrieve a strange song from it. Meanwhile, Professor Hiroshi Omae discovers that the egg glows red when frightened and that the creature inside the egg thinks Azusa is its mother due to the fact she was the first thing it heard and that it gets frightened when it can't tell she's around. When Kazuma and Miki play the song on a tape for Professor Omae, the egg begins hatching, revealing it to be a Godzillasaurus egg instead of a Pteranodon one. The baby Godzillasaurus is named GODZILLA JUNIOR. Unfortunately, Godzilla appears off the coast of Japan in his search for the baby. G-Force launches Mechagodzilla 2, who battles the monster to a standstill. When its shock anchor cables are shot into Godzilla to electrify the beast, the Monster King manages to send his energy through the wires and short out the machine, leaving it unable to move. With Mechagodzilla 2 out-of-the-way, Godzilla heads to Kyoto. When Godzilla arrives, Godzilla Junior is taken to the institute's basement in order to isolate the baby's distress calls. This works, causing Godzilla to return to the ocean. Godzilla Junior is later taken to a Monarch facility in Japan for safe keeping and study. Monarch scientists soon discover that the baby has a second brain in its hips that helps control its lower body functions. Assuming that this is the same for Godzilla, G-Force begins working on the G-Crusher System, which will be installed into Mechagodzilla 2, to destroy Godzilla's second brain in order to paralyze him from the waist down. They plan to use Godzilla Junior to lure Godzilla to the one of the Ogasawara islands where the attack will take place. At this time, the children from the Psyionics Center sing the plant's song to Godzilla Junior, but causes the baby Godzilla to slam against the bars on its environment cage due to the massive intake of power the song gives him. On Adonoa Island, the plant's music allows Rodan to absorb the nuclear waste on the island, transforming him into FIRE RODAN. With his transformation complete, he begins searching for his "brother" as Junior and Azusa are loaded into the container for use in the G-Crusher plan. On the way to the attack point, the helicopter transporting the container is destroyed by Fire Rodan, who takes it to Tokyo. By nightfall, Fire Rodan soon arrives and Garuda is immediately deployed to get Fire Rodan away from the container while Mechagodzilla 2 finishes its integration of the G-Crusher System. Garuda arrives and it isn't long before the airship is temporarily defeated, but Mechagodzilla 2 arrives just before Fire Rodan can return to the container. Fire Rodan makes the mistake of attacking Mechagodzilla 2 with his Uranium Heat Beam, but that only charges the machine's Plasma Grenade. One single Plasma Grenade shot nearly kills Fire Rodan, leaving the giant Pteranodon wounded badly and bleeding on the ground. As a team of soldiers try to free Junior and Azusa from the container, Godzilla arrives on the scene and battles Mechagodzilla 2 once more. Later on, Garuda rejoins the fight and combines with MG2 to create SUPER MECHAGODZILLA. Super Mechagodzilla manages to knock out Godzilla with tranquilizer missiles and uses the G-Crusher System. Godzilla's second brain is destroyed, leaving the Monster King paralyzed on the ground. After Super Mechagodzilla rains hundreds of laser beams onto Godzilla, he finally dies. Godzilla's death gives Godzilla Jr the power to break out of the container and let out a loud distress roar to Fire Rodan. The giant irradiated Pteranodon awakens after hearing the roar and flies over to Godzilla's dead body. He begins transferring the nuclear waste energy he received from Adonoa Island into Godzilla, which heals his second brain and revives Godzilla while Fire Rodan returns to his Rodan form. Godzilla uses the energy he has received from Rodan to destroy Super Mechagodzilla with his new Spiral Fire Ray. Fearing that Godzilla Junior will just be used as a decoy again in another scheme to kill Godzilla, Azusa has Miki telepathically tell Junior that he has to go with Godzilla. Understanding what he needs to do, Godzilla begins heading back to the sea with Godzilla Junior and Rodan following him.
1994
• Project T, a plan to place a telepathic amplifier onto Godzilla in order to control the monster with telepathy, and Project M, the creation of the new anti-Godzilla weapon M.O.G.U.E.R.A. (Mobile Operations Godzilla Universal Expert Robot Aero-type) from the remains of Super Mechagodzilla and reverse-engineering both of the Mysterians' Mogueras, are completed.
• The members of Project T (Major Akira Yuki, Dr. Chinatsu Gondo, Miki Saegusa, Koji Shinjo, and Kiyoshi Sato) are dispatched to Birth Island where Godzilla, Rodan and Godzilla Junior, whose height is now up to Godzilla's lower waist, are currently living. Although Yuki is on the team, he has a vendetta against Godzilla due to the monster killing his best friend and Chinatsu's brother, Goro Gondo, back in 1989. As the team is getting set up, a giant humanoid crystal organism from outer space destroys a NASA space shuttle as it approaches Earth. With the members of Project T getting set up on Birth Island, the EDF has G-Force deploy M.O.G.U.E.R.A. to intercept and stop the space monster. M.O.G.U.E.R.A. battles the crystal organism outside of Earth's orbit, but the crystal organism ends up badly damaging the robot, sending it back to Earth for repairs. The crystal organism heads for Birth Island in order to kill the Earth's most powerful monster. When it lands on the island, it starts creating crystals in the ground that begin giving it energy. Godzilla Junior and Rodan go to check it out, but Rodan is blasted out of the sky by the crystal organism's Corona Beam. With nothing to protect Godzilla Junior, the crystal organism uses telekinesis to lift the young saurian into the air and place him in a crystal prison. Rodan becomes airborne again and rushes to free his brother. Picking up Godzilla Junior's telepathic distress calls, Godzilla emerges from the ocean and rushes onto Birth Island. As Godzilla moves inland, Shinjo and Sato manage to shoot the amplifier onto the back of Godzilla's head. Godzilla quickly joins Rodan in assaulting the crystal organism, but it uses its cosmic powers to knock them both away as it flies to Fukuoka, carrying the crystal prison holding Godzilla Junior with it. Godzilla and Rodan quickly follow in pursuit while Yuki radios in a helicopter to take them back to the mainland. The crystal organism lands in the center of Fukuoka and begins transforming the city into its crystal fortress by causing numerous crystals to erupt out of the ground all over the city. It looks upon the tallest structure in the city, which is Fukuoka Tower, and transforms it into its energy conductor. Right next to Fukuoka Tower, the crystal organism sets down Junior's crystal prison and then it just waits. The Project T members make it back to the mainland and Yuki, Shinjo, and Sato are sent to pilot M.O.G.U.E.R.A. against the crystal organism while Miki and Chinatsu are flown to Fukuoka by helicopter so that Miki can control Godzilla using the psychic amplifier. When Godzilla and Rodan arrive in Kagoshima Bay, Yuki sends M.O.G.U.E.R.A. to kill Godzilla. Before M.O.G.U.E.R.A. deviates too far off course, Shinjo knocks Yuki out and puts him in the backseat while he and Sato take control of M.O.G.U.E.R.A. and send it back on course. Once in Fukuoka, Rodan and M.O.G.U.E.R.A. try clearing a path through the sea of crystals, but they are repelled by energy waves until Godzilla arrives. The crystals that are keeping Junior prisoner begin glowing as they siphon a little bit of DNA from him, which the crystal being absorbs into its body to transform itself into SPACEGODZILLA. With Miki's influence, Godzilla joins M.O.G.U.E.R.A. and Rodan as a team player against SpaceGodzilla. Realizing the tower is how SpaceGodzilla gets its cosmic energy, Miki relays a plan to M.O.G.U.E.R.A.'s crew, Godzilla, and Rodan on how to destroy the tower. M.O.G.U.E.R.A. splits into the Star Falcon and Lang Moguera in order to carry out the plan. While the Star Falcon and Rodan distract SpaceGodzilla from the air, the Land Moguera burrows underground and destroys the tower's foundations and superstructure, allowing Godzilla to knock over the tower. The tower falls on top of SpaceGodzilla, burying it under rubble. When SpaceGodzilla emerges from the rubble, it's pretty pissed off. It uses the last of its cosmic energy to fire the giant crystals around it into the air and rain them down like missiles onto its enemies, badly wounding Godzilla, nearly kills Rodan, and damages M.O.G.U.E.R.A. badly in the process. When M.O.G.U.E.R.A. uses its Spiral Grenade Missiles to destroy SpaceGodzilla's shoulder crystals, robbing the cosmic saurian of even more energy. Using its tail, SpaceGodzilla impales M.O.G.U.E.R.A. in the chest and immobilizes the robot. Without its shoulder crystals to regulate its cosmic energy, SpaceGodzilla's energy core causes a massive black hole to appear above the planet that starts sucking debris and crystals into it. Thankfully, M.O.G.U.E.R.A.'s crew, Miki, and Chinatsu get to safety somewhere stable and avoid getting pulled inside, but M.O.G.U.E.R.A. isn't as lucky and is pulled into it. Before the black hole could grow too large, Godzilla rips out SpaceGodzilla's energy core and absorbs the energy inside it. This causes the black hole to weaken some, but it's not until Godzilla blasts SpaceGodzilla into it with a powerful Spiral Fire Ray that the black hole collapses and disappears. With SpaceGodzilla gone, the remaining crystals explode into shards and Godzilla Junior is finally free from his prison. As Godzilla, Rodan, and Godzilla Jr head back to Birth Island, Miki uses her telekinesis to remove the telepathic amplifier from Godzilla due to the fact that he saved the Earth once again.
• Project CyberLizard is completed, which is the construction of the anti-Godzilla weapon CYBERSAUR for G-Force's American branch.
1995
• Godzilla's nuclear heart starts going haywire, transforming him into BURNING GODZILLA. Birth Island is destroyed and sinks into the ocean due to Godzilla's new form causing an explosive chain reaction with the massive amounts of uranium deposits on the island. Godzilla Junior and Rodan are presumed dead, but Miki Saegusa continues to search for them in hopes that they're still alive. In his pain-wracked state, Godzilla shows up in Hong Kong and rampages through the city. Kenichi Yamane, the adopted grandson of the famous Dr. Yamane, announces that Godzilla's malfunctioning heart is beginning to overload because of the large overdose of alien energy he absorbed last year, along with the uranium deposits on Birth Island. The result of this is that Godzilla will explode and destroy all of Japan. Due to Godzilla's highly unstable state, G-Force begins constructing freezer weapons and equips the Markalite Squadrons with anti-nuclear cold weapons. At the same time, the Gotengo is being suitably equipped with said freezer weapons. Meanwhile in the Ariake district of Tokyo, construction of an underwater tunnel is interrupted by a series of strange events. Soil samples taken from the area later reveal that this was the area where the Oxygen Destroyer was used against Godzilla I in 1954, and that microscopic lifeforms dating back to the Precambrian era, possibly mutated by the Oxygen Destroyer, are living there. The creatures make it into the waters of a nearby aquarium and kill every fish in there. Elsewhere, Godzilla appears off the coast of Okinawa heading for a nuclear power plant to feed. The Gotengo is deployed and freezes him solid using its anti-nuclear cold weapons. This freeze-down causes his body temperature to go down and slow his metabolism, ending the threat of Godzilla exploding. Instead, a far worse scenario rears its ugly head. Instead of exploding, Godzilla will now meltdown once he reaches 1200 degrees Celsius, burning a hole into the Earth's core that will destroy the planet. Miki finally finds Godzilla Junior and Rodan when Junior comes ashore at a public beach where Rodan is resting. Due to the Birth Island Incident, Godzilla Junior has mutated into a sub-adult. Meanwhile, the microscopic creatures, named DESTOROYAH, have managed to create human-sized Juvenile forms for themselves and have begun combating JSDF forces in Tokyo. When Monarch scientists discover that the Destoroyah shy away from freezing temperatures, freezer weapons from the Markalite Squadron are brought into play. Unfortunately, the assault only causes the Destoroyah to merge together to create a giant Aggregate form that eradicates the military forces. G-Force soon learns that Godzilla is following Junior and decide to use that to their advantage by having the psychics Miki Saegusa and Meru Ozawa use their psychic abilities to bring Godzilla Junior and Rodan to Tokyo so that Godzilla will follow and hopefully fight Destoroyah. When Junior and Rodan arrive in Tokyo, the two kaiju fight the Aggregate Destoroyah, who switches between its Aggregate and Flying forms several times. They are victorious in the end, but Junior does sustain a minor chest wound during the confrontation. When Godzilla arrives, he meets up with his adopted son and Rodan in Narita, but Destoroyah returns in its enormous final form and grabs Junior, taking him high into the air. Rodan tries to stop the demon, but he's knocked out of the sky with a single swat of Destoroyah's tail. In an act of pure sadism, Destoroyah drops Junior from an incredible height on top of a building, instantly paralyzing the adopted son of Godzilla. This enrages both Godzilla and Rodan, who attack Destoroyah with utter viciousness until the monster is destroyed in an explosion of micro-oxygen. Godzilla and Rodan go over to the dying Junior, but Godzilla's attempts to revive him are met with failure as Junior's eyes close for the final time. Destoroyah reforms himself and begins its final showdown with Godzilla as the Monster King approaches his meltdown. Rodan assists Godzilla once more until the Monster King's power becomes too unstable, causing the mutated Pteranodon to retreat from the area. The Gotengo finally reaches the battlefield that is Haneda Airport along with the other Markalite Squadron freezer weapons as Godzilla unleashes his full fury on his son's murderer. With the Gotengo's anti-nuclear cold arsenal, Destoroyah is killed for good just as Godzilla reaches 1200 degrees Celsius. As Godzilla begins melting down, the Gotengo and the freezer weapons unload everything they have on him in order to keep him from destroying the planet. Their mission is a success, but the radiation Godzilla's released is enough to make Tokyo uninhabitable for quite some time. That is, until the radiation levels start going down due Godzilla Junior absorbing the radiation, mutating him into GODZILLA III.
• Highly intelligent alien lifeforms possessing remarkable telepathic abilities called DOGOLAS arrive on Earth from a distant Nebula. The male Dogolas comes across Las Vegas in search of food for its mate and begins using his telepathic powers to influence the minds of those on the Strip to come out to the desert. Having been informed by this strange phenomena, Dr. Kagaku sends his friend Kino and Také, Reiko's brother, in G-Force's V. . craft to investigate. Upon arriving, they see that the Dogolas are consuming the humans they have under their control. Kino makes the mistake of attacking them, but it only alerts the aliens to their presence. They manage to take over Kino's mind, but Také is able to resist their mind control. Seeing that the aliens are making Kino fly the V.T.O.L. straight at the male, Také manages to knock him away from the controls and fly the ship back to the American G-Force headquarters in Salt Lake City, Utah. After getting out of range of the Dogolas, Kino is freed from the aliens' influence, but doesn't remember anything after flying over the desert. Once Kino and Také report back to base, Dr. Kagaku and Reiko begin discussing ideas with their think tank. A plan is made involving a device that will block the Dogolas' influence being placed on Cybersaur so that the mecha's pilots can control it without falling under alien control. While the device is being made, a squad of remote-controlled anti-kaiju vehicles created by the U.S. military are sent to distract the Dogolas. Although the attack is predictably a failure, it does buy enough time for the device to be created and installed on Cybersaur. Fortunately, the assault causes the Dogolas' to briefly lose control of their human meals. Instinctively, the people begin running to safety, but the Dogolas head back into Las Vegas in search for more to feed on. As the Dogolas begin destroying the city in their search, Cybersaur finally arrives. With its variety of lasers and missiles, the Dogolas are killed, proving that Cybersaur is a success.
1996
• Godzilla III heads for the small island of Kiryoku-shima. While the monster advances, the Markalite Squadron tries to hold him off while the island's inhabitants are evacuated. The island's priestess sacrifices her soul to the demon GEKIDO-JIN in order to drive Godzilla away. Gekido-jin comes back to life and battles Godzilla. Although the new King of the Monsters manages to destroy the stone demon several times, Gekido-jin keeps coming back bigger and stronger until their battle takes them to the edge of the island. Both kaiju fall off and plummet into the ocean. Under the ocean waves, Godzilla blasts the stone demon to rubble one last time before swimming away. The statue of Gekido-jin reforms underwater, trapping the priestess' soul inside it forever. Godzilla swims away from Japan in search of new territory.
• Godzilla is found month's later in the mid-Pacific, sleeping at the surface of the water. Dr. Kagaku, Reiko Kagaku, Kino, Také, and some U.S. Navy personnel are monitoring the monster while on board an aircraft carrier in case he wakes up. As Monarch research boats begin showing up to study Godzilla, Professor Noriko Yoshiwara, the daughter of Dr. Yoshiwara who discovered the radioactive slab in 1954, and Burton Helzer arrive on board one the research vessels. Once Professor Yoshiwara and Burton introduce themselves to the brains behind G-Force's American branch, Dr. Yoshiwara heads up on the deck of the aircraft carrier in order to get a closer look at the monster. As Burton distracts the others below deck, Yoshiwara opens up the case she has carried with her and assembles a Stinger-Class missile launcher. Before anyone on deck can stop her, she fires a hypodermic missile at Godzilla. The missile hits Godzilla and begins injecting a toxin into his blood stream that she created specifically to kill him as revenge for killing her family many years ago. The toxin awakens Godzilla, sending him into a fit of pained rage. With Godzilla awake, the aircraft carrier personnel begin to evacuate as the ship begins opening fire on Godzilla in order to divert his attention from the fleeing Monarch ships. Kagaku and the others escape in G-Force's V.T.O.L. along with Yoshiwara and Burton. Godzilla smashes the aircraft carrier before the toxin fully takes effect, causing him to sink beneath the waves. Yoshiwara explains to Kagaku and the others about what she did, with Burton confessing that he knew what she planned. Both Yoshiwara and Burton join G-Force's American branch in order to make sure Godzilla is truly dead, as well as make sure that her poison doesn't have a harmful effect on the environment. After zero sightings in a month, Godzilla is presumed dead.
• Project Arachnid and Project Mothra are completed, which is the construction of the ALL-TERRAINTULA and MECHAMOTHRA respectively.
• 5 months later, G-Force's American branch locates Godzilla off the coast of British Columbia, bleeding profusely due to the effects of Yoshiwara's toxin. Kino and Také are dispatched in the V.T.O.L. with a portable version of the bird call device Professor Hayashida created in '84. Godzilla soon makes landfall in Canada, but Dr. Kagaku convinces Colonel Cameron to hold back Cybersaur so that the bird call can be used successfully. Canadian fighter jets launch a brief assault on Godzilla which ends when the G-Force V.T.O.L. arrives. Like his father in 1984, Godzilla immediately begins following the flying vessel out to sea. Suddenly, the bird call device shorts out. Without the call distracting him from the pain Yoshiwara's toxin is giving him, Godzilla is immediately wracked with it and takes his anger out on the V.T.O.L. by blasting it with his Atomic Ray. The beam only clips the flying vessel, causing it to crash-land in the Canadian wilderness. Kino and Také survive, but when they find the portable bird call device they discover that it was sabotaged (the one who did this would later be revealed to be Colonel Cameron). With the bird call device deemed a failure, Dr. Kagaku gives Cameron the authority to deploy Cybersaur as the Canadian military assaults Godzilla. When Cybersaur arrives, Godzilla takes a pounding from the mecha due to his weakened state, but that causes the pilots to underestimate him, Godzilla manages to knock Cybersaur offline with a powerful blast of his ray and leaves the area. Kino quickly helps Cybersaur get back online while the Canadian army plans to force Godzilla into a lake filled with gasoline and electrical wires with a large assemblage of their artillery. Predictably, the plan fails, but it does buy enough time for Kino and the surviving Cybersaur pilots to repair the mech. Cybersaur fights Godzilla once again, but this time the battle ends when Cybersaur seemingly kills Godzilla with its G-Buster cannon. Godzilla's pain-filled roar sends vibrations deep into outer space that draws an enormous space bat named BAGORAH to Earth, along with a space ship belonging to the Dianii, a race of alien big game hunters, who are hunting the Korghan beast. Meanwhile, Godzilla's motionless body is being studied by Monarch and guarded by G-Force while Colonel Cameron takes Professor Yoshiwara and Burton into custody for the possible environmental threats Yoshiwara's toxin may have caused. Noticing the arrest, Kagaku has Cameron take them to G-Force's headquarters in Utah. While detained, Yoshiwara decides to heal Godzilla with the antidote she made for her toxin. After escaping her cell with Burton's help, Yoshiwara gets the antidote and flies a spare V.T.O.L. to Canada. Bagorah soon arrives on Earth and tries to feed on Godzilla, but Cybersaur begins to battle it. As the battle goes on, Yoshiwara arrives and fires the antidote at Godzilla. Bagorah manages to defeat Cybersaur with its Sonic Screeches and prepares to feed on Godzilla just as the monster recovers. Godzilla starts fighting Bagorah, but he's unable to use his Atomic Ray due to still being weak from the toxin. Nevertheless, Godzilla defeats Bagorah and follows it to Vancouver. Colonel Cameron notices Yoshiwara in the V.T.O.L. and has the flying vessel shot down so he can arrest her. Kino realizes that Cybersaur's fuel tanks are going to explode, so with the help of Také and Dr. Kagaku, he rescues the crew inside before it goes up. Once Godzilla reaches Vancouver, he and Bagorah battle again, but Godzilla has regained his Atomic Ray during his pursuit. After using it to mortally wound Bagorah, the giant space bat flies off for parts unknown. Satisfied with his victory, Godzilla begins heading for Portland. Cameron arrests Yoshiwara and takes her to a military prison in the States. After learning that only she can make the toxin that nearly killed Godzilla, Cameron kills Yoshiwara and explains to the guard outside that she committed suicide. The Dianii arrive in Earth's orbit days later and begin scanning the planet for the space bat's location. They soon discover that Bagorah has been wounded badly by Godzilla after watching a news feed of the battle. Deeming Bagorah unworthy to hunt, the Dianni decide that Godzilla would be a much better trophy and head for Earth. Meanwhile, Godzilla is advancing towards Portland as G-Force and Colonel Cameron watch as the All-Terraintula and Mechamothra arrive to stop the monster. The Dianii arrive in the city and spot Godzilla battling the mechas. When Godzilla is shot by the All-Terraintula's Super Tranq missile and has cadmium dust rained on him from Mechamothra's wings, the Dianii decide to intervene in order to prevent Godzilla from being injured. The group of five fifty-foot aliens use their Mega-zookas to knock the two mechas out of commission and then begin to revive Godzilla using electrical shocks from their weapon, the Jump Starter. Godzilla comes to after the second shock and attacks the Dianii administering the shocks, killing it. The Dianii flee as Godzilla gets up so they can regroup and launch a joint attack on him. Announcing that the Dianii ship is a threat, Colonel Cameron takes his troops, along with Také and Kino, to gain control of it while the aliens are preoccupied. Dr. Kagaku, Reiko, and Burton try to convince the Dianii to stop their hunt so they don't endanger any lives in Portland, but the Dianii just ignore them and start attacking Godzilla. The intergalactic hunters shoot him with large arrows, bind his legs together with a grappling cable, and throw an electrical net on him. Unfortunately for them, Godzilla is still able to fight even after all that and he kills two of the Dianii while the others regroup for another attack. Colonel Cameron and his men enter the ship, knock out the female Dianii on board and take control of the alien vessel. After doing that, Colonel Cameron reveals to Kino and Také that he and his troops are actually Simeon insurgents from the Simeon colony on Planet X who have come to take over the Earth. "Colonel Cameron" explains that with the Dianii ship, he will lead an armada of Simeon ships that have been hiding on Earth to destroy the Earth's military forces and place Godzilla under Simeon control using stolen Xilien mind control technology in order to attack Earth's cities. As the alien ape spills his plan and reveals that he killed Yoshiwara in order to prevent her from creating more toxin, Také keeps his radio on for Kagaku, Reiko and Burton can hear as they fly to the ship. "Colonel Cameron"calls in the Simeon fleet, the All-Terraintula and Mechamothra, ordering an all-out assault on both Godzilla and the Dianii. The combined assault from the Simeon fleet and the two mechas causes Godzilla and the Dianii to temporarily stop attacking each other and start working together. They manage to destroy most of the Simeon fleet, but all but one of the Dianii dies. The last surviving Dianii flings the All-Terraintula at Godzilla, who absorbs the nuclear energy it stole from Godzilla inside it before destroying the spider robot and Mechamothra. When the female Dianii recovers from unconsciousness, she helps Také and Kino disable the Dianii ship's shields just as Godzilla blasts it. The female Dianii escapes with the humans escape in a small lifeboat, but the Simeons on board die as the Dianii ship slams into the ground. With the ship's destruction, the final Dianii rushes into the flames of the burning vessel to end his life due to the belief that he is trapped on the Earth. After dropping off Také and Kino, the female Dianii flies the lifeboat back into space and Godzilla leaves Portland.
• Bagorah arrives deep in the forests of Nigeria and begins healing its wounds.
• A logging company in the forests of Hokkaido uncovers the subterranean prison of DESGHIDORAH. Seeing the pendant on it as a great present for his daughter when he returns home, the foreman boss removes it. Belvera, seeing the amount of destruction humanity has caused on Earth over the past century, wishes to release Desghidorah to destroy humanity. Belvera tracks the girl down and just as she's about to steal the pendant, Moll and Lora arrive to stop her. Fairy Mothra and GARU-GARU battle it out, but in the end Belvera gets the pendant and flies Garu-Garu back to the forest. Using the pendant, she places the foreman boss under her control and has him free Desghidorah by destroying the tomb using a bulldozer filled with dynamite. Moll and Lora are forced to call in Mothra despite the fact that she is weakened from old age and having just recently created an egg. Despite her failing strength, Mothra arrives and battles Desghidorah with all her might, but it isn't enough. Sensing that the adult Mothra is dying, Mothra's egg on Infant Island hatches prematurely. The little larva inside crawls off the island and begins swimming to Japan to assist his mother. As the larva arrives, Desghidorah badly wounds the adult Mothra. The larva uses powers never before seen in a Mothra larva before him to attack Desghidorah, but they aren't strong enough to harm the demon. Desghidorah grabs the larva in his jaws and nearly crushes him before the adult Mothra blasts the three-headed demon with her antenna rays. Unable to fight anymore, Mothra uses the last of her strength to carry her son away from Desghidorah, but she dies mid-air over the ocean. The little Mothra larva watches helplessly as his mother's dead body sinks beneath the waves. Needing to evolve soon if he wants to defeat the killer of his mother, the larva begins swimming to the Tree of Life and cocoons himself against it. The spirit of Earth begins giving energy to the cocooned larva in order for him to be strong enough to handle the threat. Meanwhile, Desghidorah rampages across the land, destroying forests and cities in order to replenish his strength. When the cocoon breaks open, millions of butterflies emerge and reform into MOTHRA LEO. Mothra Leo flies as fast as he can to Desghidorah's location and battles the dragon to avenge his mother. Using powers that were gifted to him by the spirit of the Earth, Mothra Leo beats Desghidorah and destroys him once and for all. Seeing all the destruction caused during the fight, Mothra Leo uses the power of life that's inside him to restore the plant life lost.
• SASORI breaks out of the cavern underground Area 51 and escapes into the Nevada desert. Needing the creature brought back, Monarch has the U.S. military and G-Force head out to stop it, but when the military finds Sasori, it's already in Blackstone, Nevada attacking the city. An airstrike is called on the giant scorpion once the city is evacuated, but the fighter jets fail to puncture its massive exoskeleton. The monster scorpion continues heading east and soon runs into Godzilla (he was returning to the sea, but Sasori's presence caused him to head to California) in Death Valley National Park. At first the creatures fight, but when another airstrike is called in, the two kaiju work together to fend off the attackers and become friends in the process. Following the airstrike, G-Force sends an experimental weapon created by Dr. Kagaku called the Grinder, a large armored drilling vehicle equipped with an energy field and a plethora of missiles, in to stop them. Kagaku, Také, and Reiko watch the battle in the V.T.O.L. and hope that the Grinder will drive off Godzilla and weaken Sasori. Kino, who is piloting the Grinder, manages to keep both kaiju at bay. When Sasori is badly wounded by the machine, Godzilla becomes enraged. Godzilla tells Sasori to flee while he fights the machine. Sasori complies and scurries off to safety while Godzilla continues fighting the Grinder, but when it's obvious that Godzilla's going to win, Kino bails from the machine minutes before Godzilla destroys it. With his enemy destroyed and his friend safe, the saurian turns away and heads back to the ocean.

• With ocean pollution increasing, DAGAHRA is brought out of slumber and with him are his BAREM. The Barem are discovered by fishermen as the starfish begin killing all sea life along the Okinawan coast. Seeing the threat Dagahra and his starfish pose to the world, Moll and Lora begin searching for the lost temple of Nilai Kanai in order to find the GHOGO in order to destroy the Barem. Unbeknownst to the Shobijin, their sister Belvera is also searching for the Ghogo and has found the key to make the temple rise from the depths of the ocean. Sensing the temple's re-emergence, Dagahra begins rampaging across the coastal cities of Okinawa to reach the temple in order to finish off the last remnants of his creators. Moll, Lora and Fairy Mothra battle Belvera and Garu-Garu in order to prevent the evil Elias from getting the Ghogo, but their battle is interrupted when Dagahra arrives. The temple's defenses are unable to hold off the monster, so the Shobijin call Mothra Leo to battle the beast. Unfortunately, Dagahra manages to pull Mothra Leo underwater during the battle and attacks him with Barem. Now covered in Barem, Mothra Leo manages to fly out of the water and collapse on top of the temple. With Mothra Leo in such a critical state, Moll and Lora battle with all their might to get the Ghogo so that it can heal Leo. Unexpectedly, the three Elias' battle takes them right into the treasure room. Belvera and Garu-Garu try to steal the Ghogo so that Leo will die, but she immediately stops when Battra arrives. Having been reincarnated by the spirit of Earth again, Battra emerged from his egg in Siberia when Dagahra returned, sensing the threat he poses to the Earth. Moll and Lora point this out to Belvera, causing the elder Elias sister to have a slight change of heart when she lets her sisters use the Ghogo. As Battra battles Dagahra, the Shobijin take Ghogo up to Leo, who not only heals him, but transforms him into RAINBOW LEO. Rainbow Leo joins Battra against Dagahra, switching between his rainbow form and aqua form, AQUA LEO, to effectively combat the pollution beast until their combined power kills Dagahra. The Ghogo uses the last of its life force to wipe out the remaining Barem. As the Nilai Kanai temple sinks back into the ocean, Rainbow Leo, the Shobijin, and Fairy Mothra return to Infant Island while Belvera and Garu-Garu follow Battra back to Siberia.
• A giant monster attacks San Javier, Peru, and since no one was able to clearly see the monster, it's believed to be Godzilla. G-Force's American branch heads to San Javier with a group of Monarch scientists to investigate. The scientists quickly learn that this creature is a completely new kaiju due to the lack of radioactivity in the area which is usually associated with Godzilla attacks. This new creature is jokingly name BURTANNUS after Burton Helzer, who believed the Monarch scientists were right about this being a new monster. While Kagaku calls in the Peruvian military just in case the kaiju comes back, Kino and Také join the Monarch scientists when they follow the trail of destruction to a deep fissure in the ground. As the Peruvian military arrives and Kagaku, Reiko, and Burton help give supplies to the villagers, Godzilla emerges from the ocean. Having been drawn here by Burtannus, Godzilla begins searching for her, ignoring the Peruvians' attack. Meanwhile, Kino, Také, and the scientists are investigating the fissure's interior when they discover baby monsters inside, along with their mother. Outside, Godzilla finds Burtannus' location and dives under the ocean. Using his powerful strength, Godzilla begins tearing the sea floor apart and digs into Burtannus' burrow. The humans manage to escape just in time to avoid the sea water that rushes into the lair due to Godzilla's sudden arrival. Burtannus begins battling Godzilla in order to protect her babies, forcing him out of her burrow and back into the ocean. After she manages to drive Godzilla off with her electrical ability, Burtannus and her infants head out to sea to find a new place to live. Godzilla heads east, sensing a new mutation has been created.
• Dr. Yamazaki invites several nuclear physicists to her facility on Lord Howe Island in order for them to inspect her nuclear reactor. After their job is done, she reveals that her creation, the LORD HOWE MONSTER, lives inside it. In order to demonstrate its might, she releases it onto the boat where the physicists' families are. The Lord Howe Monster smashes the boat and escapes. When Yamazaki discovers that it's heading for Godzilla's current location near Australia, she allows the monster to go fight him. Upon finding Godzilla, the Lord Howe Monster battles him underwater that soon leads inland from Manly Beach to Sydney. Godzilla ends up badly wounding the monster, sending it retreating back to Lord Howe Island. Godzilla follows the creature and kills it upon reaching the island. After the battle, Godzilla destroys Yamazaki's base as he searches for her nuclear reactor, killing Yamazaki and the nuclear physicists. Once Godzilla recharges, he begins swimming back to Japan, sensing a great evil approaching.
• Godzilla's random appearances around the world inspires Yuji Shinoda and his daughter Io to create the Godzilla Prediction Network as a means of tracking Godzilla in order to predict when the monster will make landfall so that citizens can be evacuated ahead of time.
1998
• On Infant Island, Belvera arrives on Garu-Garu in order to steal the Secret Power of the Elias. The following battle between the Elias sisters and their bodyguards ends with Belvera being driven away, but not before she steals one of the tiny triangles that make up the Power of the Elias. Moll and Lora realize that the triangles power up their daggers when Moll puts her triangle into her dagger, but Lora's is unable to power up due to Belvera accidentally snatching Lora's triangle. Meanwhile, GRAND KING GHIDORAH returns to Earth in order to finish the job it started 65 million years ago. Encasing itself in a meteor, it places itself in a meteor shower and crashes in the forest of Mt. Fuji. Grand Ghidorah emerges from the meteor and begins searching for a new source of energy. Since most of the dinosaurs are gone, Grand Ghidorah turns to children, for they have a huge amount of spiritual and biological energy that Grand King Ghidorah needs. The evil dragon begins flying around the Tokyo and Fuji areas, teleporting the children it comes across into a giant dome near Mt. Fuji. Moll, Lora, and even Belvera, know that Grand Ghidorah is a threat to the entire Earth and must be stopped. After a brief reunion, they power up their daggers and combine their swords together to form the Sword of Hope in an attempt to shatter the dome from the outside. Unfortunately, Grand Ghidorah infiltrates Lora's mind and learns of their plan. Sending tentacles from the dome, Lora, Belvera, and Garu-Garu are pulled inside, but Moll and Fairy Mothra manage to get away to safety. Rainbow Leo quickly engages Grand Ghidorah in battle and is soon joined by Battra, now in his imago form. The two moths are unable to damage him due to his scales' manipulation of their energy attacks to form a protective shield around him. Realizing that Leo might be able to stop Grand Ghidorah in the past after he's weakened by Gigamoth, Moll uses the last of her energy to send Rainbow Leo back in time by transforming him into LIGHT SPEED LEO. Battra is left alone to battle Grand Ghidorah, but that isn't for long because Godzilla unexpectedly comes to his aid. Even with the combined might of Godzilla and Battra, Grand Ghidorah is able to hold out. After what seemed like an eternity, but was only ten minutes, the ground behind Grand Ghidorah explodes upward and catches the attention of all three kaiju. Rainbow Mothra emerges from his time capsule cocoon as ARMOR LEO. Even with armored moth's power, Grand Ghidorah is able to hold out against all three of them. While watching the battle, Lora realizes that the three kaiju are unable to truly beat Grand Ghidorah due to the dome giving him unlimited energy. Belvera realizes that since the dome is impenetrable from the outside, it has to be destroyed from the inside. Having seen that the interior has a corrosive effect on the interior, Belvera knows that she has to do this because Moll needs Lora. Getting on Garu-Garu with the Sword of Hope, Belvera is hesitant at first to, but when Battra telepathically encourages her, Belvera has Garu-Garu charge at the dome and slam into it while she slashes it with the sword using all her might. Her efforts cause the dome to finally break, freeing the children inside and cutting Grand Ghidorah off from their power. Without the extra power to use in order to keep up his protective barrier, Armor Leo, Battra, and Godzilla are able to damage Grand Ghidorah until Armor Leo kills him once and for all by using Transcending Fate. Once Grand Ghidorah's body crystallizes and explodes into hundreds of pieces, his reign of terror ends once and for all. With his job done, Godzilla returns to the sea for some much-needed rest. Lora carries the dying body of Belvera to their weakened sister Moll, who has become crystallized. In order to bring her out of her crystallized state, the two sisters must give her some of their energy. Although this means Belvera's death, the elder Elias sister agrees to it. After the deed is done, Moll returns to life as Belvera dies. Armor Leo releases his armor and emerges from it in his Mothra Leo form. Battra returns to Siberia to hibernate and Leo takes his priestesses back to Infant Island.
• A research facility in French Polynesia manages to get Godzilla cells from Bio-Major for use in experimental research on animals. The scientists inject the cells into an iguana, a squid, a Central American worm, a king cobra, and a komodo dragon. Within the next few days, the creatures mutate and grow in size, but soon the creatures become too unruly and escape captivity, all of them heading for different parts of the world. The French Secret Service is sent to find all the creatures and eliminate them in an effort to cover-up their government's involvement.
• The mutated iguana created from the French Polynesia experiment attacks a Japanese fishing ship off the coast of Jamaica and sinks it. French foreign intelligence agent Phillipe Roaché and his men question the sole survivor of the shipwreck about what attacked them, who responds: "Gojira." Monarch and G-Force investigates this more thoroughly, with Monarch forming a team consisting of NRC scientist Dr. Nick Tatopoulos, biologist and animal behavior expert Dr. Elsie Chapman, and robotics engineer Dr. Mendel Craven, who are all under the command of Colonel Anthony Hicks. While Hicks, his army men, and the science team are in Jamaica investigating, Phillipe and his agents are investigating as well. Upon the team's return to New York City, with Phillipe and his men following them, the creature appears on land and is mistaken for Godzilla (it would later be proven that this creature is a different animal entirely, leading to its name being changed to ZILLA). Zilla rampages through the streets of New York City, forcing the city to evacuate in order for the U.S. military to combat the creature. Zilla manages to hide in the city and evade the military's attacks until he is baited with a large pile of fish. The trap fails, leading to the destruction of the Chrysler Building and Zilla escaping once more. Nick manages to find a blood sample which he uses to discover that the creature is pregnant and reproduces asexually, explaining that he's collecting food for his offspring. Before Nick can get a search for Zilla's nest permitted by the military, the news plays footage from a classified tape that Nick's reporter girlfriend Audrey Timmonds stole from his tent in order to get a story. Nick is kicked off the team and is kidnapped by Phillipe when he tries to head for the airport. Phillipe explains that he and the French government know the creature is not really Godzilla, and want they it destroyed. Nick leads Phillipe and his men in search of Zilla's nest, with Audrey and her camera man Victor "Animal" Palotti following them. Meanwhile, Zilla is drawn out again and another attack occurs, but he flees into the Hudson River and is supposedly killed by torpedoes from two nuclear powered submarines. Nick and the others soon find the nest inside Madison Square Garden just as BABY ZILLAS begin hatching from hundreds of eggs. With all of the humans smelling like fish, the babies instinctively begin hunting them. Unfortunately, all means of reaching the military from inside the building is down, but when Audrey does an interview with Nick using the camera equipment for her news station inside, showing the Baby Zillas roaming all over Madison Square Garden, the military are able to see the report and call in an airstrike on Madison Square Garden. With only five minutes to get out before the airstrike begins, some of Phillipe's men are killed by the Baby Zillas, but Nick, Audrey, Animal, and Phillipe manage to escape before the bombing. All of the babies are killed are in the blast, but the adult Zilla arrives and sees the carnage. Noticing the group of four humans, he rightly assumes they killed his babies and begins angrily chasing after them. Getting in a taxi cab, they drive through the city as fast as they can with Zilla chasing after them until they lead him to the Brooklyn Bridge. As he runs through the bridge, his dorsal fins start getting caught in the bridge's steel suspension cables. Once Zilla is unable to move, F-18 Hornets fire 12 missiles into his body. Zilla is killed and the city celebrates. In the aftermath, Nick joins Colonel Hicks and some of his men to make a clean sweep of the nest in order to make sure nothing survived. Nick ends up getting separated from the others and falls into some of Zilla's saliva before coming across a surviving egg. The egg hatches and the baby who was inside is just about to attack Nick before it smells its father's scent on Nick, causing it believing Nick is its dad. The infant is scared into the Hudson by Nick when he hears Colonel Hicks and his men approaching.
• With the Baby Zilla's disappearance, Nick forms HEAT (Humanitarian Environmental Analysis Team), which consists of himself, Elsie, Craven, his intern and techno wiz Randy Hernandez, Craven's robot NIGEL, and Phillipe's protegé Monique Dupre (who is secretly ordered to kill this new Zilla and any other G-Cell mutations). Monique provides the team with a boat which Randy later calls the HEAT Seeker. Reports of a new mutation in Jamaica keep Monarch and the U.S. military busy while HEAT searches for the Baby Zilla. The baby, soon dubbed ZILLA JR, returns to HEAT's headquarters on Staten Island days later, but has grown to the size of a sub-adult over the short period of time. For the next week, Nick, who is seen as an adopted father to Zilla Jr, and the others study him (They discover that Zilla Jr is unable to reproduce) until Monique secretly calls Colonel Hicks and G-Force. The army tries to kill Zilla Jr as he retreats into the ocean and is presumed dead when they don't pick him up on radar. With Zilla Jr gone, HEAT goes to Jamaica to investigate the new mutation. Once there, the HEAT Seeker is attacked by GIANT SQUIDS, who have been coming close to shore and attacking people recently. Just when it seems like the squids are gonna get the HEAT team, Zilla Jr, now a full-grown adult, comes to their rescue and fights the squids. They later discover that the real mutation is CRUSTACEOUS REX, who has been hunting the giant squid for food and in the process, forcing them to shallower water. Zilla Jr and C-Rex battle, which ends with Zilla Jr killing the mutated squid. After the battle, Zilla Jr, now re-named Zilla, manages to get away from the military in time. Monarch scientists studying Crustaceous Rex reveal that the creature contains G-cells in its body.
• For the rest of the year, HEAT, along with Zilla, go all around the globe fighting new mutations that are created by man or just pop up. While chasing around mutations, they also study Zilla and learn that his underwater lair is close to their HQ. Throughout this period of HEAT's battle against mutations, Monarch and G-Force try to kill Zilla due to believing he's just another rampaging monster. Joining the threat against Zilla is Nick's rival Cameron Winter, the owner of Solstice Technologies, who tries to take control of the monster using his Cyber Flies to implant experimental mind-control technology reverse-engineered from "borrowed" Xilien technology into Zilla's ears. The mutations HEAT and Zilla fight are the NANOTECH CREATURE (a petroleum-eating microbe colony that is originally invented to settle the sanitation worker strike in New York City, but its size increases at an out of control rate due to a bug in its systems), EL GUSANO GIGANTE (the Central American worm G-Cell mutation created by French Polynesia that begins attacking Central America due to the rare and poisonous flower it's attracted to eating), GIANT RATS (rats that were mutated by consuming the radioactive fish the first Zilla left in the sewers of New York City), the CRACKLER (a creature created and brought to life in New York City by insomniac Sydney Walker's theta waves and suppressed rage), and the GIANT MUTANT BEES and the GIANT MUTANT QUEEN BEE (mutant giant bees on the island resort of Santa Monica created by an irradiated volcanic eruption).
1999
• Xenobiologist Dr. Alexander Preloran and his assistants Dr. Hans Sopler and Dr. Ted Hoffman discover the Tachyon vessel Leviathan and go aboard, only to be captured by the surviving Tachyon aliens that came out of suspended animation when the humans were detected in the ship by the ship's sensors. They take Dr. Preloran as a mental captive and absorb the three scientists' knowledge on Earth. Deciding that Earth is suitable to their needs, the Tachyons decide to colonize it and use humanity as their slaves. Needing to download their minds into human hosts to survive on Earth, the Tachyons release a signal that lures in the HEAT team, as well as awaken various mutations across the planet to use as mind-controlled slaves in their invasion. While this is going on, two Tachyons implant their minds into Sopler and Hoffman. When HEAT arrives where Preloran's ship is waiting for him on the surface, they discover that the scientists never returned, so they head down to the ship in a submersible vehicle of their own. Zilla helps them reach the ship by battling the CRYPTOCLEIDUS that guard the vessel. Nick and the others avoid the REPTILIANS patrolling the halls of the ship and discover what the Tachyons are up to. HEAT manages to destroy the controls for the Tachyon ship, ending the monster attractor signal. After breaking free from the Tachyons' mind control, Dr. Preloran sacrifices himself to allow Nick and the others, including both Doctors Sopler and Hoffman, to escape. The Cryptocleidus attempt to attack them again, but Zilla attacks both creatures and kills one in a rock slide while the other one retreats. For the next following months, HEAT and Zilla go up against the mutations who are awoken by that brief monster attractor signal; those creatures being QUETZALCOATL (an ancient bird living in an Aztec temple in the Southern point of Mexico that attacks the nearby villages), the ICE BORERs (a group of mutated moles living in Antarctica that are able to control their body heat), MAGUMA (a giant walrus living in Antarctica that was thawed out of the glacier it was frozen inside of by the Ice Borers' heat), NESSIE the Loch Ness Monster (an ancient Mosasaur that survived the great extinction who is actually disturbed by a scientist kidnapping her baby), KING COBRA (the king cobra G-Cell mutation who begins attacking hikers near Mt. Fuji after being disturbed by the Tachyon's monster attractor signal), ROBO-YETI (a mecha created by Dr. Yukiko Ifukube and G-Force's American branch for use against Zilla and other mutations; it's destroyed in Zilla's battle against King Cobra), and the GIANT MUTANT TERMITES (giant mutant termites that are sent into a frenzy by the Tachyons' signal and begin devouring the South American rainforest).
• 5 months after destruction of the Leviathan, Craven picks up a Tachyon signal coming from Sandy Point, New Jersey that Dr. Sopler tries to intentionally hide from HEAT. The signal awakens a fully healed BAGORAH who begins attacking villages in Nigeria. Nick, Randy, Monique, and Craven go to Sandy Point and discover that Dr. Hoffman is there with Colonel Hicks, his men, and Elsie, who are all under Tachyon mind control. Also, the remains of the Leviathan are stored in the hangar. When HEAT begins arguing amongst each other thanks to Tachyon influence from Hoffman, they are escorted out by Hicks' men, but not before Monique places a hidden transmitter on one of the crates there. When the team tries to go back, Sopler uses his Tachyon influence to make the team argue again, causing Nick to go to Nigeria alone. Upon arriving in Nigeria, Zilla begins fighting Bagorah and during the fight, Nick reunites with Randy and Monique on the HEAT Seeker. The Tachyon inside of Sopler takes control of the Bagorah, forcing it to leave the fight and go to Site Omega. While Randy and Monique follow Bagorah in the HEAT Seeker, Nick flies back to New York to meet up with Craven. After checking Monique's spy camera and seeing that the Leviathan is gone, they decide to go investigate Sandy Point again. Using a spy bug from NIGEL, the two discover that the ship has been taken to a mysterious location called Site Omega. Meanwhile on Site Omega, Anguirus, Rodan, Kamacuras, Kumonga, Titanosaurus, Gorosaurus, the Giant Mutant Bee Queen, Burtannus, Ebirah, and King Kong are on the island, all of them under Tachyon control. While tracking Bagorah, Monique and Randy mess with its radar and cause it to fight the recently surfaced Cryptocleidus, causing the monsters to fight until the Tachyons stop them. Meanwhile, Nick and Craven are forced to enter Sandy Points' base when NIGEL's spy bug malfunctions, discovering CYBER-ZILLA and TECHNO-SENTIENT, who are under Tachyon control, in the process. The Tachyons are soon alerted to Nick and Craven's presence, causing them to send Cyber-Zilla and Techno-Sentient to kill them. Sensing that his adopted father is in danger, Zilla comes to their rescue, but the shock of seeing his biological father allows the Tachyons to take control over his mind. It isn't long before Monique and Randy, Nick and Craven, and the rest of the monsters under Tachyon control arrive on Site Omega. With an army of monsters under their control and HEAT taken prisoner when they tried to shut down the Tachyons' transmitter, the Tachyons release the monsters on Earth's major cities in an effort to weaken the world's military forces so that the main Tachyon invasion fleet will be unopposed when it comes. The order to attack is given and the monsters are unleashed. Bagorah attacks Paris, Cyber-Zilla and Techno-Sentient attack Tokyo, Titanosaurus attacks London, the Cryptocleidus attacks Hong Kong, Burtannus attacks New Kirk City, Zilla attacks Washington D.C., King Kong attacks New York City, Gorosaurus attacks Portland, Kamacuras attacks Sydney, Kumonga attacks New Guinea, Anguirus attacks Amsterdam, the Giant Mutant Bee Queen attacks Mumbai, Ebirah attacks Venice, and Rodan attacks Sochi. Nick, Monique, Randy, and Craven manage to escape and go to stop the Tachyon transmissions in order to free the monsters. After they succeed in doing that, Monique temporarily frees Elsie from the Tachyons' control as well. Unfortunately, the Tachyon invasion fleet has arrived and some of their ships have already started attacking cities with some assisting Cyber-Zilla and Techno-Sentient in destroying Tokyo. The other monsters start fighting back against the Tachyon ships, but King Kong, the Cryptocleidus, Bagorah, and the Giant Mutant Bee Queen are killed by them. Joining the Cryptocleidus against the Tachyon fleet is Eternal Leo, Godzilla arrives in Tokyo to fight Cyber-Zilla and Techno-Sentient and causes them to retreat from the city by battle's end, and Battra shows up in Moscow to help Burtannus take down some alien ships. While this is going on, HEAT destroys the psionic amplifier array, preventing the Tachyon ships from communicating with each other. When Cyber-Zilla arrives at Site Omega, Zilla follows it and battles his cyborg biological father in order to save Nick. When the theta wave dish controlling humans is destroyed and both Techno-Sentient and Cyber-Zilla are killed, the Tachyon invasion is called off and the remaining ships fly back to their home planet. When the Tachyons base is destroyed by G-Force, the Tachyons inside Sopler and Hoffman die, returning the doctors back to normal human beings. After the Monster Wars are over, Zilla is granted amnesty by G-Force thanks to some convincing from HEAT and due to his help in stopping the Tachyon Invasion.
• Site Omega is turned over to both G-Force and Monarch under orders from the United Nations and the EDF. The island is renamed Monster Island with the purpose of containing the world's monsters in order for the scientists of Monarch and the scientists of the world to study them in a safe environment. Anguirus, Rodan, Gorosaurus, Ebirah, Kamacuras and Kumonga, Titanosaurus, and Burtannus are transported to Monster Island and are contained in habitats specifically designed to meet their needs.
• HEAT continues the battle against mutations that have now been awoken by the Tachyon transmissions calling Earth's monsters to what was once Site Omega. Monsters that Zilla and HEAT battle after the Monster Wars include the CHAMELEON (a mutation created by Cameron Winter to attack New York and frame Zilla in order for G-Force to kill the mutated iguana), the GIANT MUTANT WIDOW SPIDER (a mutation that awakens in Palma due to the Tachyons' signal and begins producing enough eggs to overrun the U.S.), the SUB ZERO MANTA (an oversized manta capable of producing ice blasts that was trapped in an iceberg in the arctic and ends up lost in Jersey because of the Tachyons' signal), the SWAMP BEAST (an ancient protector of the Louisiana bayou that is awoken by the Tachyons' signal and comes to stop aristocrat Paul Dimanche from trying to make riches off of the bayou's precious resources), SKEETERA (an enormous mosquito that was awoken by the Tachyons' signal and begins attacking Miami, Florida), and the MEGAPEDE/CICADA (a mutated hybrid of a centipede and a cicada that was awoken underground by the Tachyons' signal and starts attacking the American Midwest).
• Tobias Wilson discovers other mutations awoken by the Tachyons' signal and captures the GIANT GILA MONSTER in the Arizona desert, SASORI in the Nevada desert, MEDUSA on a pacific atoll, and other unnamed mutations in order to start the Mutant Mania circus.
• After learning that the Tachyon ship was discovered under the ocean, the Crisis Control Institute is created as a faction under both Monarch and G-Force that is dedicated to finding possible threats on the Earth and neutralizing them. Mitsuo Katagiri is named the head of CCI. When Professor Shiro Miyasaka discovers the Millennian ship in the Japan Trench, he informs Katagiri, who orders the craft raised to the surface for study. Meanwhile, Godzilla appears off the coast of Tokai and heads for the nearby nuclear power plant. Katagiri notifies G-Force, who deploy Markalite Squadron personnel and vehicles launch an attack on him at the coastline using the newly created Full Metal Missile Launchers. Also on the scene is Yuji Shinoda, his daughter Io, and photographer Yuki Ichinose. As Godzilla is led away from the nuclear plant, Shinoda goes to investigate Godzilla's footprints and discovers a piece of his flesh which was blown off. Meanwhile, CCI's submarine fleet finds the Millennian UFO, which is now encased in seafloor rock, and begin attaching balloons on it in order to raise it to the surface. When the lights of the submarine shine on the Millennian vessel's internal power source comes back to life and turns every system on. While the ship is being raised to the surface, the Millennian inside receives the message about its home world's devastation. With enough energy stored to surface on its own, the Millennian craft shoots out of the water, removes its rocky casing using energy shock waves, and begins scanning the planet to see if its environment is right for colonization. The scans show that surviving Millennians would need certain genetic information inside them to survive, the Millennian begins scanning for creatures with that exact genetic info. It scans the nearby humans, but they don't have the right information. The ship flies off and in its search comes across Godzilla. After scanning its genetic make up, the Millennian discovers that Godzilla has the exact genetic information its been searching for. It has the ship attack Godzilla with its Atomic Concussion Cannon, but the monster proves to be stronger than it thought. Godzilla escapes into the sea after being hit with the cannon a second time, so the Millennian flies to Tokyo to find more information on him. Meanwhile, Katagiri allows Shinoda to use CCI's laboratory to examine the Godzilla skin sample as long as he shares his findings with CCI and Monarch. It is there that Shinoda and Miyasaka discover the secret of Godzilla's regenerative healing ability, which Shinoda names Organizer G1. Not wanting to share this information to the CCI, fearing that they would simply use it to kill Godzilla, so Shinoda tries to download the data onto his own discs, but is caught by Miyasaka. Before anything can be done, Miyasaka receives information about the Millennian vessel heading for Shinjuku. By nightfall, the alien craft arrives in the city and lands on top of City Tower where it begins draining every file about Godzilla from EDF, G-Force and Monarch databases. Katagiri orders the building to be destroyed and stands by his decision even when Shinoda enters the building in order to get Yuki out before the blast. The detonation happens on schedule and Shinoda luckily survives it. As the humans head to the top of CCI headquarters to see what the Millennian UFO would do next, Godzilla arrives in the city and heads straight for it. A small battle takes place between saurian and saucer, but the confrontation ends when the UFO buries Godzilla under a building. Using its energy tentacles, the Millennian harvests a small bit of Godzilla's Organizer G1 from the rubble and merges it with its anti-matter body. Wanting to test its new body, the Millennian exits the ship and takes on a physical form. At first things are alright, but soon it starts mutating into the monster ORGA. Godzilla bursts out of the rubble and begins fighting Orga, who continues draining genetic material from Godzilla with every bite and claw stab. When it tries to attack Godzilla with its UFO, Godzilla destroys the vessel with his Atomic Ray and damages Orga badly when the beam brushes against Orga's shoulder. Unfortunately, when Orga regenerates the damage, it reveals that its healing factor is much faster than Godzilla's. Even when Godzilla blows up most of Orga's body with his Atomic Ray, the alien kaiju regenerates the damage. With no other options left, Orga opens its mouth extremely wide and attempts to swallow Godzilla whole in order to complete its transformation. Godzilla bravely goes into the alien kaiju with a plan in mind. More and more of Orga becomes Godzilla-like as the saurian goes further inside until Godzilla unleashes a powerful Nuclear Pulse that destroys Orga from the inside out. As Orga's body crumbles into dust, Godzilla roars in victory before heading over to where Katagiri is and kills him by destroying the ground beneath him. With his enemies vanquished, Godzilla returns to the sea. The CCI is disbanded and the Godzilla Prediction Network takes its place.
• Monarch scientists Ishiro Serizawa and Vivienne Graham are called to a quarry in the Philippines where an excavation crew has discovered an enormous sinkhole containing a giant skeleton of an unknown creature along with two egg-like spores. One of them is destroyed while the other one is intact. A large hole on the opposite side reveals that the creature who hatched has escaped into the sea. The intact spore is discovered to be highly radioactive so American personnel remove it and take it to the Yucca Mountain nuclear waste repository. The creature that hatched begins swimming to Janjira nuclear power plant in Japan and burrows underground to feed on the reactor's radiation. This causes an explosion in the plant that threatens to release radiation into the air, as well as the complete destruction of the power plant. Janjira is evacuated and quarantined with the incident covered up by Monarch as an earthquake. The creature cocoons itself on the reactor and continues feeding off it while Monarch begins monitoring the creature.
