In the last instalment, the Rangers used the power of the 4 Legendary Cosmo Spheres to disrupt the barrier around the Dark Nebula. They then launched their attack on Planet Black, splitting up to infiltrate the palace. Tarrant's group discovered the fate of Earth's Power Rangers, Yuri ended up left for dead at the hands of the empowered Dark Soul and Mila's group faced down the Victorious Generals Coiloga, Tricerodo and Katseayor, who fused into a new being, identifying as Aporioshi.
As Mila's group looked on, even Cha-ChaMari seemed shocked. "Aporioshi? He was my father's greatest friend and most devoted follower. How did he come from the three Victorious Generals?", she thought to herself.
In the room itself, the 4 Rangers looked on in shock at the sight. "That's impossible.", Proton exclaimed. "I fought and destroyed you before. How are you alive?"
"It's true that the attack with your sword left me critically wounded.", Aporioshi answered him. "However, my growth implant preserved my essence, although it was damaged as well. I was only able to be restored as three aspects of my personalities. Katseayor, my warrior's spirit, Tricerodo, my ability to emphasise and cunning, and Coiloga, my ruthlessness and lust for power."
"So all this time our three greates opponents… were really one split into three.", Myron commented.
As if on cue, Slash, Barry and Jiro ran into the room, launching their attacks on Aporioshi. However, he turned around and grabbed all three of them with his claw arm. "I see your friends have seen fit to join us.", he commented as he threw them aside. "Unfortunately, my splinters have allowed me to improve my body significantly." He launched his ball at the Rangers, knocking them back. "And now you shall witness my secret power. Thanks to the three aspects of my self, I have attained an Ultimate Growth Implant!" His legs began to glow as his body expanded, taking down a significant portion of the building through his growth. "Witness the Herculean Power I possess!"
"I see he's just as theatrical as the rest of them.", Mila noted. "Shall we?"
"But how?", Cobras asked. "It's impossible without Yuri or the Commander."
"Not quite.", Jiro said. "I still have the All Zords Sphere. We can control the Lion Zord without him."
"Then what're we waiting for?", Slash asked. "Let's do it."
Everyone prepared their Zords except for Cobras and Jiro, who instead ran off, deciding to look for something else.
Down in the lower levels, Tarrant's group also saw this. "Looks like we're needed.", Drago said as he saw the giant Aporioshi.
"I'll stay behind.", Winda insisted. "All these people need some help reacclimatising to being awake."
"Well don't be too long.", Tarrant told her. "We need all the help we can get. Especially Yuri, wherever he is." He, along with Drago and Scales, proceeded to summon their Zords and fly into the battle.
Gingaku witnessed the Rangers incoming. "Launch everything we have.", he demanded. "Aporioshi needs all the help he can get."
"Already on it.", Cerebron nodded, pressing buttons on a console.
The Rangers found themselves under fire from giant Commanagas, Giant Neo-Bullroids and Gearoids. "These guys won't be trouble.", Drago said as he crashed his Dragon Zord into three of their targets, destroying them. "Now, let's combine."
"Alright.", Barry and Myron responded. The three combined with Barry taking his place as the right arm, while Myron became the left arm. Proton meanwhile transformed the Fire Voyager into its Megazord mode.
The two Megazords landed, standing back to back. "Let's take out these guys together.", Proton said to the others.
"We can do that.", Drago replied as he moved towards three giant Commanagas, who he swiftly beat his way through. A Neo-Bullroid fired on Proton, who slashed it into submission quickly and then moved onto a Gearoid.
The Lion Zord then combined with Yellow as the right arm, Black as the left arm, Green as the right leg and Gold as the left leg. They soon found themselves under fire from several enemies. "It's not easy without Yuri.", Mila noted.
"We have to try anyway.", Slash insisted. The Megazord moved forward, shrugging off the hits from the enemy before facing two Commanagas and a Gearoid. It cut down its opponents just as the Fire Voyager continued to make progress on its opponents.
Proton then received a message from Cha-ChaMari, who was piloting the Gearoid. "I just thought you should know we have your bird friend. He's waiting in Daddy's throne room for you."
"Corvin.", Proton said to himself. "But how?"
"That's for me to know and you to find out.", Gingaku's hooded figure appeared. "But the truth may not be what you want to hear." He then turned to Dark Soul, who was waiting with a Neo-Bullroid. "Your friend the Red Ranger is still alive. Find him and destroy him."
"It will be done.", Dark Soul said as he stood up and departed.
As the Cosmo Megazord continued to beat back his opponents, Proton prepared his final attack. "Burning Transmission Strike!"
The blast hit Cha-ChaMari's Gearoid, causing it to catch fire. "I'll be waiting near the throne room.", she said as she teleported out.
The Dragon Star Megazord them used an energised punch to take out a few of its opponents, blowing them all up. It then came under fire from a Gearoid and it's partner. "There's too many of them.", Drago stated. "We need to keep pushing."
He then received a message from Winda. "I've found Yuri. Or rather, the Legend Rangers did. One of them used her jumping skills to stop him from falling to his doom. He's currently unconscious from his injuries and it is unknown when he will wake up."
"I hope it's soon.", Mila replied as the Rangers came under fire once more. "We could use the help here."
As the army charged once more at the Rangers, the Megazords unleashed their final attacks on them, wiping out the army in an instant. "Where's that Aporioshi?", Proton asked. "I'd like to settle thing with him."
As if on cue, Aporioshi landed on the ground, towering over the three Megazords. "You're all like ants compared to me.", he announced. "I let that army soften you up so I could crush you here and now."
"So those robots were a diversion.", Drago commented. "I should've realised."
Aporioshi used his ball and chain to attack the three Megazords, causing them to spark. "Now behold more of my power." He fired a beam from his chest, that was only stopped by the Cosmo Megazord using the Defend-24 Cosmo Sphere. But even that didn't fully negate it, as the three were still blown apart by the force of the hit.
"We need more power.", Proton said.
As if on cue, the Shooting Star Megazord appeared, as the twelve Zords combined into one. "Let's end this now.", Proton said as he activated the Zodiac Megazord's final attack, launching all the Cosmo Spheres at the enemy.
However, Aporioshi only absorbed that energy. "That won't help you.", he boasted. He then fired another beam, that knocked the two Megazords back, the Shooting Star falling down dead.
On the ground, Yuri, now demorphed, regained consciousness. He saw a blonde woman sitting nearby. "It's ok.", she assured him, with a very soft voice. "You're safe now. I broke your fall."
"Thanks.", Yuri said. "And you are?"
"Zoey. Zoey Reeves. I'm one of the various Power Rangers that have protected Earth over the years. I woke up a few minutes ago and got told by an android named Winda to look for others. I saw you falling to this level and decided to save you."
"Falling? I was dropped.", Yuri stated. Then he had a realisation. "Dark Soul. He's still out there. I need to…"
"You don't need to do anything.", Winda insisted as she approached with the Ninja Steel Rangers. "For now, you should rest up for a while longer. These Legendary Rangers can handle themselves until I find a way to send them home."
"Winda, am I glad to see you.", Yuri said as he went over to his teammate and hugged her. "Where are the others? And while they're here, what're these Legendary Rangers doing here?"
"To answer your first question, they're occupied fighting one of Gingaku's strongest warriors. All except Jiro and Cobras, who're currently fighting the Detainers on the top floor to clear a path to the main antechamber. As for these Rangers, from what I've gathered, they were taken here and kept in stasis so that Gingaku could drain the energies from the Morphin' Grid itself. For what, I'm not sure."
"Too bad you won't get to find out.", Dark Soul said, bursting into the room. "Did you really think you could hide yourself from me in here?", he asked. "I know every inch of this Palace inside and out."
"Who's this creep?", the White Ninja Ranger asked.
"He's the Dark Soul I was telling you about.", Yuri said. "We used to be friends, but that's no longer the case." He stood up to fight, but quickly staggered.
"Yuri, you're still hurt.", Zoey insisted. "I'll handle this creep for you. Transport!" She pressed the bracelet on her wrist. However, nothing happened.
"You fool, your teleporter signals are blocked inside this place.", Dark Soul said as he knocked her aside with his sword. "You can't stop me from getting to Yuri."
"She doesn't need to.", Yuri said. "Injury or no injury, I can still face you." He pulled out his Big Bang Sphere and pressed the button on top. "Big Bang Energy, Unleash!" He inserted it into his Morpher, pressing the top again and spinning the dial. After the Morphing was complete, he ran forward with his Cosmo Saber to fight his opponent, barely holding him back. "I'm still not giving up on you.", Yuri told Dark Soul.
"Then you're a fool.", Dark Soul replied as he blasted Yuri back with his new powers. He ran forward and struck with his sword, Yuri barely dodging the hits, before ascending up the nearby stairs. "The friend you knew is long gone. And he's never coming back."
Yuri kicked his opponent away and ran up the stairs, with Dark Soul in hot pursuit.
Outside, Aporioshi continued beating down the Zodiac Megazord while the Shooting Star lay in ruins. "Let's try something else.", Proton suggested. "He's anticipating everything we've thrown at his splinters."
"He won't see this coming then.", Drago replied. As the Zodiac Megazord split apart, the Cosmo and Dragon Star Megazords reformed into the Cosmo Dragon Megazord, which had the Balance Zord taking the place usually occupied by the Wolf Zord.
"A new form won't help you.", Aporioshi fired another beam at his enemies.
"Wanna bet?", Drago replied. The Cosmo Dragon Megazord walked through the smoke, unaffected by the shot.
Elsewhere, Jiro and Cobras had dealt with a group of Detainers. "We've got the easy part out of the way.", Jiro said. A pair of Commanagas appeared and then began firing missiles at them. "Now comes the hard part."
"I can handle these two.", Cobras said as he pulled out his Void Sphere. "You go help the others."
"Don't have to tell me twice.", Jiro said as he ran off.
Cobras then inserted his Void Sphere into his Morpher, transforming into his powered up mode with a declaration of "Dark Energy, Unleash!" Now transformed into Void Mode, he inserted his Black Hole Sphere onto his Cosmo Scythe. "Let's see how you like this. Black Hole Glaive!" He slashed at the two Commanagas, defeating them handily. "And now, onto the rest.", he said as he ran off.
Outside, Aporioshi prepared another attack. "Take this.", he declared, firing his beam once more.
"That won't help you.", Drago said as he opened and closed the head on his cane. "Cosmic Dragon Master Blast!"
The two beams ended up clashing in mid air. "What's the matter, Rangers? Not enough juice?", Aporioshi mocked. Eventually, the two beams ended up shorting each other out, knocking Aporioshi back momentarily. When he looked back, the Rangers were gone. "I'd better get moving.", he said as he walked off.
In Gingaku's antechamber, Cha-ChaMari gave a report of the scene to her father. "The Rangers seem to have fled at the first opportunity. Without their leader, they're powerless against Aporioshi."
"Speaking of whom," Gingaku responded "where is he?"
"I'm right here.", Aporioshi's voice announced as an image of him appeared on a screen. "I'm going to tap directly into the planet's core for more power. The Rangers won't be able to survive my next attack."
"No, my friend.", Gingaku begged. "Don't do this. If you absorb too much energy and then end up losing, you could be totally destroyed. You'd be gone again, this time for good."
"Lord Orbis, I am aware of the risks of what I am undertaking.", Aporioshi's voice echoed once more. "Let it be known, if I fail here, that it has been an honour to be your servant in both my full and splintered forms."
"You're more than just a servant to me.", Gingaku stated. "You're my friend." He signed off the screen, clearly saddened by Aporioshi's undertaking.
Elsewhere, Yuri continued his battle with Dark Soul. A battle he was on the losing end of. "Is that all you've got?", Yuri asked. "I've had colds worse than this."
"You want me to go all out?", Dark Soul asked. "Very well. I'm shrouding my self in the darkness of the night." He surrounded himself with his dark aura, transforming once more into Yamashi. "Let's see what this additional power can do." He summoned up Metaro's bow-staff and aimed at his opponent. "Say goodbye." He fired arrows at his opponent.
Arrows that were quickly blocked by the arriving Super Ninja Steel Rangers. "Get to safety.", Yellow suggested. "We'll handle this guy."
"You don't have to tell me twice.", Yuri said, pulling out his Lion-01 Sphere and using it to summon his cockpit, flying off.
"Don't think you can keep me from him for long.", Yamashi growled. "I'll just defeat you and then find him." He summoned up Cha-ChaMari's club and then charged at them. The Rangers however blocked with their swords and began fighting him off using their Element Power Stars' various attacks. He buffeted all of the hits, before seeing Lion Fire Red and Super Ninja Gold running towards him and attacking with their respective final attacks, which pushed him back further. "I'll admit. I gave you less credit than I thought you'd earned. You're just as powerful as him."
"Well we've been beating creeps like you for years.", Gold commented. "Time to finish this."
The 6 Rangers prepped their respective firearms, the regular Rangers' Ninja Blasters and Gold's Rockstorm Guitar and aimed them at Yamashi. "Ninja/Rockstorm Blast!" The 6 beams hit Yamashi, knocking him out of the building. "Show's over. Ninjas win!"
Elsewhere, the Rangers that had been in the Megazords regrouped near the crashed Shooting Star. "How's it doing?", Myron asked his brother.
"Not good.", Heath replied. "Without the Big Bang or Orion-13 Spheres, I cant make any major repairs."
"You have them.", Yuri said as he and Jiro both showed up, the former handing Orion-13 to Heath. "What's the rest of the situation like?"
"Not good.", Mila answered him. "We barely made it out of anything and Aporioshi disappeared to who knows where."
"Myron's scanner indicates that he's in the planet's core.", Barry said. "I'm not sure what he'd be doing there."
"Nonetheless, we should make sure he never comes out of there.", Drago said. Then he noticed a particular absence. "Where's Cobras?"
"He's still on the upper levels.", Jiro answered. "Fending off the enemies up there so we have a clear path to Gingaku."
"I'd bette help him.", Scales decided. "He might miss one." He summoned his Zord and took off.
"That just leaves the 9 of us to take on Aporioshi.", Tarrant noted.
"That's all we need.", Yuri told him. I have a plan."
In the planet's core, Aporioshi saw the Shooting Star heading towards him. "A single ship? You think this will stop me?" He was then hit with a blast."
"No, but it will distract you.", Yuri said from within the Astral Leo Megazord. He fired again, knocking Aporioshi away from the core.
"Not enough energy… absorbed.", Aporioshi said. "But it's enough." He was then hit by the Fire Voyager, who knocked him through the planet's crust, back to the city.
Aporioshi now found himself facing three Megazords, all in their default formations. "It's time to end this, Aporioshi!", Proton stated.
"At the hands of three that can become one, I might add.", Drago added, trying to invoke irony.
"Let's hit 'im with all we've got.", Yuri said as he had Astral Leo fire more shots at the enemy.
"You won't take me down, even with Astral Leo's power.", Aporioshi declared as he blocked the shots then threw his ball at the Megazords, which was blocked by the Fire Voyager.
"Time for some extra power.", Yuri said, inserting his Big Bang Sphere. "Summon Shooting Star Ship!"
The Shooting Star Megazord formed once more, joining the others. It fired at Aporioshi, injuring him. "Let's channel our powers at this guy.", Astral Leo suggested.
"Burning Transmission Strike!"
"Dragonic Break!"
"Astral Projection Break!"
The three blasts were absorbed by Aporioshi, who felt weakened by the energy. "It's too much.", he said, before laughing. "Just kidding." He then fired the three beams back at their senders, knocking the Megazords back.
"We're losing badly.", Astral Leo stated.
"Don't you think we know that?", Yuri said with frustration. "We need to get back in there."
The Shooting Star then began a wrestling match with Aporioshi, being knocked back. "Let's see if the brainwashing gas Tricerodo used on your friend works on robots." He blasted the Shooting Star with said gas, which caused it to go berserk and attack the other Megazords.
"He's out of control.", Heath called out as he was buffeted from inside the Megazord. "Do something."
"On it.", Yuri said as he shot at the Shooting Star, disrupting it long enough for the other two to hold it down. "We need to target that nozzle."
"No problem!", Astral Leo stated, firing on the part of Aporioshi composed of Tricerodo's weapon and shattering it. The Shooting Star returned to normal and blasted the enemy with the heat from its thrusters.
"Now to finish this.", Yuri said. "Big Bang Strike!" He pressed the button and spun the wheel. The Shooting Star launched its astral Cosmo Sphere at Aporioshi, damaging him significantly.
"How is this happening?", Aporioshi asked. "I should have the advantage of strength."
"I've been through this with Coiloga.", Yuri answered him. "We have the advantage of friends on our side. While you're all out here alone."
"And that will be your downfall, just like Coiloga.", Proton stated.
"Let's go Astral Leo, everyone.", Yuri said, as the four Megazords launched their beams at Aporioshi, damaging him significantly. "Now then, let's use the Big Bang Cannon!" The Astral Leo Megazord detached the Leo Zord, returning to being the Cosmo Megazord. It then swapped arms with the Dragon Star Megazord and stood behind the newly transformed Big Bang cannon with the Fire Voyager. All twelve Rangers were teleported into the cockpit. Yuri grabbed onto the rifle. "Everyone, grant me your powers." Everyone nodded as the lights emerged from all of them, channelling into the rifle.
"Ultimate Galaxy Blast!", the Rangers all declared.
"This won't be the end.", Aporioshi said, generating another beam to attack with.
12 beams came from the cannon, to be met with the Aporioshi's beam. But this time, the Rangers won out, destroying their opponent completely.
"This Space is ours.", the Rnagers all declared. All except one.
"Not quite.", Proton said. "There's still some unfinished business." He took off in the Fire Voyager, flying upwards.
"Proton… Kyle, wait!", Yuri called out, as Drago could only look down in shame.
In his antechamber, Gingaku could only look on at the sight of Aporioshi's destruction on the screen. "Father?", Cha-ChaMari said in an attempt to break the silence.
"Leave me.", was all he could say. "Now!" Cha-ChaMari pulled out of the room, deciding to escape his wrath. "No more games, Kyle.", he said, now that he was alone. "We're going to finish this now."
Elsewhere on the floor, Cobras took down another Commanaga. "I think that's about all of them.", he said as he demorphed, unaware that another was rising up behind him, ready for the kill.
A moment that never arrived, since said Commanaga was shot down by an arriving Scales, much to Cobras' surprise. "What would you do without me?", Scales asked his partner.
"I'd probably still be lost in space.", Cobras answered him. "Nice to know you're still here for me though."
The tender reunion was short-lived as Proton came running up to them. "Where is it?"
"What?", the two asked.
"The throne room.", Proton stressed. "I have to get there now."
"Hold up." Proton turned around to see Yuri, accompanied by the rest of the Rangers, including Winda, fresh from having returned the Legendary Rangers to their home planets. "What's so important that you have to get to the throne room?"
"They've got him.", Proton said. "Orbis has Corvin in the throne room. I have to get him back."
Everyone but Yuri was confused by this. "Who's Corvin?", Slash asked. "You're not making much sense."
"Corvin is an old friend of Proton's.", Yuri clarified. "He's the one who left the map to find him."
"In that case." Winda did a scan of the building's remaining structure. "You're in luck. The throne room was one of the few parts of the structure that wasn't demolished by Aporioshi's growth. It's down the corridor, third door on the left."
Proton hesitated for a moment, before speaking. "Well, what're we waiting for? Let's go."
And so the Rangers made their way to the throne room. Proton, Cobras, Myron and Yuri entered the room, but the door closed and wouldn't open before anyone else could go through. "What's going on?", Scales said as he banged on the door. "Let us in."
"Oh I don't think you'll be going in there." Everyone turned around to see Cha-ChaMari, accompanied by a Neo-Bullroid and a group of Detainers. "In fact, you're going to fall here while the biggest threats to Daddy's Power fall in there."
"Then… Proton's friend… it's a trap!", Drago exclaimed.
"And you fell for it.", Cha-ChaMari mocked.
Inside the room, the 4 Rangers realised they weren't being followed. "The door seems to be sealed.", Myron said. "We can't get out and they can't get in."
"Maybe Proton's Burning Calibur could cut through the door.", Yuri suggested.
But before that conversation could continue, they were interrupted by Proton himself. "Corvin!", he called out as he saw his friend knelt on the floor and went over to embrace him. "I can't believe I found you."
"Yes.", Corvin said. "I'm glad you managed to find me again after all this time, Kyle."
Proton immediately stopped his embrace, realising something was off. Namely that Corvin never knew him as Kyle Jennings. "How do you know my name?", he asked.
"There's nothing I don't know about you, Fire Knight." Corvin then stabbed Proton in the chest, sending him lunging backwards. Corvin then began laughing evilly, as he was surrounded by the same dark aura that Dark Soul had earlier surrounded himself with. When it cleared Corvin was gone and in his place stood…
"Gingaku!", Cobras said disdainfully.
"Yes.", Gingaku cackled. "You walked right into my trap. Today will be the end of the Power Rangers. And in particular, the Fire Knight."
