1944

• A Japanese garrison stationed on Lagos Island begins fighting off an American amphibious landing party, but they are beaten back into the jungle by the Americans. As the Japanese unit is almost wiped out by the Americans, two male GODZILLASAURS emerge from the jungle to investigate the strange noises. Both sides are taken by surprise at the sight of live dinosaurs and retreat, but while the Japanese garrison hides in the jungle, the Americans try killing them. Both dinosaurs are irritated by the bullets, grenades, and bazooka shells, causing them to attack and kill most of the American force. Once the saurians come out onto the beach, the American ship at sea opens fire on the Godzillasaurs, badly wounding one of them. The dinosaurs retreat into the jungle and the surviving Americans pull out of the island to leave. Days later, the Japanese garrison go to where the wounded Godzillasaurus lays. After thanking him for helping them and keeping them safe, the soldiers salute him and head to the boat that came to pick them up. Not too long after that, the time machine KIDS arrives from the year 1991. Before time traveling to the point where the Japanese garrison leaves Lagos, they arrived at an earlier time and watched the whole battle between the Japanese and American forces, as well as the battle between the Americans and the Godzillasaurs. Miki Saegusa uses her ESP powers to locate the Godzillasaurus who was wounded. Emmy drops off the DORATS as M11 prepares to send the wounded Godzillasaurus to the present day Bering Sea, but as the teleportation process begins, the second Godzillasaur emerges from the jungle. Thinking that KIDS is attacking his brother, the Godzillasaurus attacks the machine. No one notices that the teleportation process was disrupted slightly by the attack, which causes the wounded Godzillasaurus to time warp to the Bikini Atoll in the year 1954. KIDS tries to fly away so it can sneak up on the healthy Godzillasaurus and send him to the Bering Sea, but he takes a bite out of a critical location on the machine, forcing the crew to time warp back to 1991 in order to avoid being stuck in 1944. The Godzillasaurus goes back to his daily life.

1945

• On July 16th, the very first atomic bomb test takes place in Alamogordo, New Mexico.

• On August 6th, the atomic bomb is dropped on Hiroshima right at the time a group of Japanese scientists are examining the recently delivered heart of Dr. Frankenstein's monster in a facility within the city. The large amounts of radiation released from the bomb awakens and draws in one of the prehistoric creatures from 230 million years ago. It is first spotted by Daisuke Serizawa, who dubs it SHINOMURA.

• On August 9th, the second atomic bomb is dropped, this time on Nagasaki.

• An atomic bomb test takes place on Lagos Island, mutating the remaining Godzillasaurus into GODZILLA II and the three Dorats into KING GHIDORAH II. Godzilla fights Ghidorah II, but the saurian is driven off the island and Ghidorah II awaits commands from its masters in the future.

• Some Muans stumble upon a Japanese A-403 submarine as it dives close to their undersea kingdom, but upon boarding it they discover that the captain and its crew are gone. While investigating, they discover blueprints for a new submarine called the Gotengo that Captain Jinguji is constructing. After they take the A-403 and the blueprints back to show the Empress of Mu, she realizes that the Gotengo will have the ability to dive down deep enough to reach their kingdom. Seeing how destructive humanity has become over the years, the Empress doesn't want humans coming anywhere near her kingdom, so she orders an army of submarines like the A-403 built, but with their advanced weaponry.

• The United Nations is formed thanks to the efforts of U.S. President Franklin Roosevelt.

1946-1950

• Shinomura attacks an American ship near a South Seas island and later attacks a nuclear power plant in Novosibirsk, Russia in 1946. The Monarch Organization is formed in secret that same year for the sole purpose of studying and destroying Shinomura. Dr. Daisuke Serizawa is added to the team after encountering it once again when it fed on the nuclear energy inside the American ship. Through those years, he begins researching oxygen for a means to stop the monster.

• In 1947, Shinomura attacks Busselton in Western Australia. Godzilla II senses this creature and sees it as a threat, so he begins to track it. In 1949, Godzilla II battles Shinomura in Rotorua, New Zealand, and on the Island of Yap in 1950.

• In 1950, an ancient creature called the SILVER HYDRA is discovered roaming around inside the mine in Blind Rock, Wyoming. The miners who run across it are turned into silver statues by the creature, causing the entire mine to be shut down. With the creature left undisturbed, it goes back into the depths of the mine to hibernate.

1954

• When Godzilla II tracks Shinomura to the Bikini Atoll, he picks up the scent of his brother; the Godzillasaurus that was teleported there in 1944. Believing Shinomura would be a threat to his brother, Godzilla II battles and kills it. The Castle Bravo Test occurs in the Bikini Atoll as an attempt to kill Godzilla II, but it ends up creating GODZILLA I from the Godzillasaurus. Both Godzillas swim away into the ocean. Godzilla II heads for parts unknown while Godzilla I, angered by his mutation and humans in general, attacks a Japanese fishing vessel called the Daigo Fukuryū Maru. With both creatures presumed to be dead, Serizawa returns to Japan.

• Months later, Godzilla I causes numerous other shipwrecks, which causes an expedition team to be sent to Odo Island, which was near all the ship disasters, to figure out what is going on. A storm strikes the night of the team's stay. During the storm, Godzilla I destroys most of the village and the expedition's helicopter, but the team blames the destruction on the storm when morning comes. While going through the village, they discover radioactivity is all over and the expedition leader, Dr. Yamane, discovers a trilobite among the wreckage of a radioactive well. Godzilla I is soon spotted by villagers manning the watch towers, causing the team and the entire village to head for the hills to see the beast for themselves. When he rises up over the hills, he makes his presence known by roaring ferociously at the villagers and expedition team alike before returning to the ocean. The Japanese government tries to kill him with depth charges that they release around the area and he is believed to be dead. Meanwhile, Dr. Daisuke Serizawa shows his fiancé Emiko Yamane his completed experiment that he would have used on Shinomura; the Oxygen Destroyer. Fearing the destruction it would cause if it was ever used as a weapon against humans, Dr. Serizawa makes Emiko promise to never speak of it to anyone. Days later, a mysterious radioactive slab is discovered in Tokyo by Dr. Yoshiwara. Yoshiwara manages to translate the stab, discovering that the text explains that it will bring an "Age of Monsters" unless it is buried. He tries to inform his bosses that the stone must be returned to the ground, but they don't listen. The stone slab not only awakens Godzilla I from his undersea slumber, but also the monsters SORAN, INAGOS, and KAMERUS, attracting all of them to Tokyo. SORAN breaks free from its underground cavern in Utah and causes destruction throughout the United States as it flies toward the slab. When Soran arrives in New York City, it is killed by the Air Force, who use anti-matter missiles that are developed by scientists in Monarch. INAGOS hatches from an enormous egg in the Australian Outback and leads an army of man-sized locusts to Tokyo. The Australian military quickly takes care of Inagos and its swarm by blasting the insects out of the sky and dropping napalm bombs on to them. KAMERUS emerges from an icy glacier in the Arctic, but it is killed after an encounter with Godzilla II on its way to Tokyo. Godzilla I arrives in Tokyo and starts destroying the city in his search for the radioactive slab. The military is unable to stop him no matter what they do. Not even a barrier of power lines filled with 300,000 volts of electricity holds the monster back, and it enters the heart of Tokyo. Fortunately, foremen Burton Helzer, with the help of Dr. Yoshiwara, manages to fly the slab out to sea. Dr. Yoshiwara is killed trying to protect his wife and daughter from Godzilla I. Following the slab, Godzilla dives into Tokyo Bay after it and Tokyo is left a smoldering ghost town with many lives lost. Seeing the amount of destruction caused by the monster, Emiko breaks her promise and tells Hideto Ogata, the man she really loves, about the Oxygen Destroyer and how it can be used against Godzilla I. He and Emiko go to Serizawa's house to convince him to use it, but a slight struggle ensues between Ogata and Serizawa over the device which ends with Ogata receiving a head wound. After seeing the amount of death and destruction Godzilla I has caused, Dr. Serizawa agrees to use the Oxygen Destroyer on Godzilla. Serizawa gives his son Ishiro to the couple and burns all of his notes on the invention. Ogata and Serizawa dive down into Tokyo Bay where Godzilla is sleeping next to the stone slab. Ogata is pulled up to the surface while Serizawa activates his invention, but before the doctor can be pulled up, he cuts his oxygen tube and rope so he can die alongside Godzilla in order to prevent the Oxygen Destroyer from ever being created again. Godzilla's is destroyed with only his bones remaining. Soon after, the slab is destroyed by depth bombs and a salvage operation to retrieve the bones of Godzilla begins, with the bones being transported to a base in Tokyo for further study. The Japanese government announces that their military has destroyed Godzilla, but don't mention the Oxygen Destroyer in an attempt to sound strong after their recent defeat in WWII.

1955

• Godzilla II is spotted on Iwato Island fighting ANGUIRUS by Shoichi Tsukioka and Koji Kobayashi, two airplane fishing scouts. The two titans' battle causes them both to fall off one of the island's cliffs and into the ocean. They briefly go their separate ways until Godzilla appears in Osaka. The military attempts to lead him back to sea using flares, but this plan fails when a group of escaped convicts cause an enormous fire in an oil refinery that draws Godzilla back into the city. The flares used to lead Godzilla away draw Anguirus on to land and the two kaiju resume their battle with most of Osaka destroyed in the skirmish. Godzilla finishes the fight by ripping out Anguirus' throat with his teeth and leaves the ankylosaur in a comatose state as he returns to the ocean. Anguirus is transported to a research facility in Hokkaido in order to be studied. Weeks later, Godzilla is discovered on a floating glacier out at sea. The JSDF immediately send fighter jets to bomb the walls of the glacier in order to trap the monster inside it. Godzilla is soon buried in the avalanche of ice, forcing him into suspended animation.

• A group of five university students go to the Japanese Alps for skiing, but two of them ski further ahead of the other three. A blizzard occurs and when the students call up their two friends in the cabin below, they hear something killing them. The next day, a rescue party heads to the cabin and the students discover evidence that leans to the conclusion that their friends were killed by a large creature. Unable to search for longer than the rest of that day, the three students are forced to return to Tokyo until spring. Two of the students, Takeshi Iijima and Machiko Takeno, return when the snow has thawed with Dr. Tanaka and his expedition. Tanaka is searching for a previously unknown bipedal primate, which Ōba, an animal broker, learns about from one of his cronies. Thinking about all the money such a creature could bring him, he and his men follow the expedition so that they can capture the creature. Later that night, the SNOWMAN comes across Tanaka's campsite and Takeshi chases after it. After losing the creature, he starts returning to camp, but he accidentally comes across Ōba and his men. Not wanting Takeshi to announce their presence to the others, the cronies beat him up and throw him into a ravine where he is discovered by Chika, a member of a race of mountain-dwelling people. Upon returning with him, she is beaten by the village chief and Takeshi is tied up, gagged, and left for the vultures to eat on the side of a cliff. The Snowman, who is worshiped by the mountain people as a deity, comes across Takeshi, pulls him up, and frees him before going on its way. When Chika comes across Ōba and his men, she mistakes them for being associated with Takeshi. Using that to their advantage, they trick her into telling them where the Snowman lives. Ōba and his men soon find its cave and its child, which they kidnap for use as bait to capture the adult Snowman. Once they capture it, the villagers, informed by Chika about what she told the group of cronies, try to stop them. As the cronies fight off the villagers, the juvenile Snowman manages to escape its bonds as the men drive off. The child starts freeing its father, but when Ōba and his men discover this, they pull over and try to stop it. In the end, the juvenile Snowman is killed, enraging its father. Ōba and his men are killed by the adult Snowman before it returns to the village, destroying it out of grief and anger for its loss. Later, the Snowman comes across the expedition team's camp and kidnaps Machiko. It takes her to its lair with Tanaka and his expedition close on its heels. When they reach the beast's lair, they follow it further inside until they reach a pit of boiling sulfur. Chika comes to Machiko's rescue by attacking the Snowman with her knife, allowing Takeshi to shoot it. The Snowman falls into the sulfur pit, taking Chika with it.

• Nuclear testing awakens Meganulas from their hibernation inside of a mine in Kitamatsu. The creatures begin slowly flooding the mine in order to make it suitable to their aquatic needs and lifestyle. Even though miners are disappearing due to the insects hunger, it is believed that one of the missing miners, Goro, is the killer. That is soon proven wrong when one of the Meganulons arrives in Kitamatsu and begins causing havoc. The police manage to chase it back to the mine, but it kills some of them along the way. The JSDF is quickly dispatched to the area and one of the miners, Shigeru Kamura, goes into the mine with some soldiers to kill the beasts. When bullets fail to stop the insects, Shigeru manages to kill one of them by riding a mine cart into it, but in the process he becomes separated from the men and is knocked unconscious. When Shigeru comes to, he realizes he's in the Meganulon's lair and witnesses RODAN I hatching from the enormous egg residing there. The baby Rodan begins eating the Meganulons until none remain before flying out of the mine. The pteranodon began flying all over the globe, destroying fighter jets who dare oppose it. Eventually, it returns to Japan and begins attacking Tokyo just as RODAN II appears. With the JSDF's attack on them unsuccessful, they begin a search for the monsters which ends when they manage to find the Rodans and their nest at Mt. Aso. A plan to make the volcano erupt is put into action and the military fires every bomb and missile they have at the mountain, causing an eruption that drowns both Rodans in molten lava; neither creature unable to live without the other. Unknown to the military, the Rodans' egg still remains intact.

1957

• From the dark side of the Moon, a race of aliens called the Mysterians prepare their attack on Earth. Ever since a nuclear war rendered their home planet of Mysteriod uninhabitable, as well as the Strontium-90 mutating and contaminating themselves, the Mysterians needed a new home other than their Mothership to live on. Deciding to attack Japan, they set up a base underground the Mt. Fuji area, but they are discovered by scientist Ryoichi Shirasishi. He researches the aliens, but his findings aren't believed by Dr. Tanjiro Adachi. The Mysterians launch an attack on a village near Mt. Fuji with their robot MOGUERA. Another village is attacked, but this time Moguera is destroyed when a bridge it's walking on is blown up underneath its feet, sending it falling to the ground below where it breaks apart. Deciding to make themselves known, the Mysterians raise their dome base from under the ground and summon Japan's leading scientist to request a peace treaty. All they want is a three-kilometer strip of land and the right to marry Earth women. When the scientists of the world discover that the Mysterians have already kidnapped their selected Earth women to mate with, the United Nations declare war on the invaders. The JSDF attacks the Mysterians' dome, but they are easily stopped by the dome's extremely powerful laser. This causes the nations of the world to work together in constructing the ALPHA and BETA-Class Aerial Battleships. Once the ships' are completed, another attack is launched on the dome, but it's as much of a failure as the first one, with the ALPHA being destroyed. As humanity works together to construct the Markalite Cannons in order to reflect the dome's energy beam back at it, the Mysterians increase their demands to ten-kilometers of land. When Ryoichi discovers the Mysterians want to rule the Earth, he regrets his decision to join them and begins attacking them from inside their base, helping Joji Atsumi rescue his girlfriend and the other trapped women. While this goes on, the BETA and the Markalite Cannons begin assaulting the base. The attack soon turns out to be successful, despite the Mysterians causing a powerful flood that knocks out one of the Markalite Cannons. They release another Moguera, but it tunnels up underneath one of the Markalite Cannons and is crushed underneath the weapon. As Ryoichi destroys the last of their technology, the Mysterians flee in their saucers. The base is destroyed, as are many of the fleeing saucers, but some manage to return to the Mothership. They flee the Solar System and never return. The remains of both Mogueras are salvaged by the JSDF for reverse-engineering.

• Operation Plumbbob, a series of nuclear tests, occurs in the Nevada desert. SASORI (a giant scorpion), THORNY DEVIL (a giant thorny dragon), and the GIANT ARMADILLO are created from the Rainier shot; the first fully contained underground nuclear test. Not wanting the creatures to escape, Monarch has the creatures contained in an underground cavern in Area 51 for their scientists to study the effects of radioactivity on living creatures.
