In the last instalment of Power Rangers Cosmic Defenders, Yamashi embarked on his campaign to eliminate the last remnants of his old life, starting with his and Yuri's friend Pamela. While the Rangers fought hard to keep her out of harms way, Yamashi discovered her location as a result of a poorly timed call from Providence Base. What will the Rangers do now?

Copper Falls, Oregon.

Yuri's team were still looking over the Annihilation Gear, having deactivated it following the death of Dr. Cerebron. "Wow, this place is really intricate.", Yuri noted. "It's a shame we have to destroy it."

"I know, but it has to be done.", Myron responded. "We can't risk human curiosity resulting in this thing being switched back on. Even though we took all the juice out of this thing, there's nothing to stop a refuelling effort."

At that point, Cobras ran in. "Bad news, guys.", he reported. "Mila tells us that Yamashi has found Pamela and is closing in on her location with his army."

"We have to get going.", Barry urged. "We don't know how much time we have."

Myron hesitated, but then came to a decision. "Demolishing this place can wait. Stopping Yamashi comes first.", he called out.

"Okay then.", came Yuri's reply. "Let's move out."

Outside the structure, Tarrant and Scales were working to dispose of the Neo-Bullroids. "These guys were meant to replace me.", Tarrant said mockingly. "But they couldn't replace my superior intellect."

"Yes, 'superior'.", Scales said as he examined his specimen. "The repair system's still intact on this one."

He was interrupted in his reverie by the others running out. "There's a problem back in Corona City.", Barry yelled. "We need to go."

"Right.", Scales said in response, as he picked up something small. "Let's go."

Providence Base, Outside Corona City.

A soldier ran into the main control room, where Commander Goodman and Pamela were holed up. "Ma'am, we've got some bad news.", he reported. "Some scaly creature in white armour and a group of other sideshow freaks have shown up. And they called up a group of Gingaku's goons to attack the guards."

"It's him.", Pamela said. "I don't know how, but he found me here. I've doomed us all."

"Now now, let's not pin blame on anyone.", Goodman said in response. "If anything, it's my fault. I told the Rangers you were here, because I thought they'd managed to resolve things quickly. Evidently, I was wrong." She then turned to the soldier. "Keep trying to hold them off for now. If you fail, then simply get out of here as quickly as possible."

"Yes ma'am.", the soldier saluted as he left the room.

"What're we going to do?", Pamela asked.

"I'm going to set Providence Base to self-destruct.", Goodman answered as she began working the machinery. "Heath showed me how to when we were going over the base. We can make our escape while this creep enters the room and ends up with a face full of explosion."

Pamela thought about this for a moment, realising that her old friend would likely die. But then she reconsidered: her friend was long gone. Gingaku had seen to that. "Do it, Commander Goodman.", she urged. "Initiate the self-destruct."

Outside the structure, Dark Soul and his army were fighting the Resistance soldiers, when the 5 Rangers still in the areaappeared. "Hey, Dark Soul!", Mila called out. "You may have beaten us down before, but we're not out."

"This is the end.", Proton stated. "Right here, right n-!" He then collapsed, once more suffering the pains in his chest.

"You can't even finish your thoughts.", Dark Soul mocked. "How do you intend to finish my plans?"

"With our help." The 6 man away team jumping down to join the others. "Your ambitions end today, Dark Soul.", Yuri stated.

"So now I'm 'Dark Soul', eh?", Dark Soul asked. "I thought I was your friend Gregory."

"My friend died a long time ago.", Yuri stated. "You saw to that personally."

"But now we're going to avenge him.", Myron said, indicating the canister in his hand. "We took down Dr. Cerebron and now we're going to deal with you."

"Cerebron was a fool.", Dark Soul stated. "But I see you've managed to bring me his Dark-X. I'll just have to take it from you." He summoned up Darneko's claws and the mace used by the Cha-ChaMari clones, using them to call up their original wielders via the Anima Core. "Secure that canister."

"As you wish, sir.", Cha-ChaMari said, bowing her head. She charged at the Rangers, swinging her mace at them.

"I don't like following orders.", Darneko growled. "But you did bring me back to life, so I'll help you out." He then charged in, engaging Tarrant.

As Dark Soul left the scene, the other Rangers continued their battle with his ground forces. Mila delivered a few slashes to the baseball alien, while Yuri faced down the robot and the gear alien, knocking them back with his Cosmo Saber. "I'd better finish this quickly with the Penta Blaster.", he said, pulling out the Leo-77 Cosmo Sphere.

Cobras took out a few Detainers with his Cosmo Scythe. "I'd better power up too.", he noted as he pulled out his Void Sphere.

But before either could use their Cosmo Spheres, both were grabbed out of their hands by Kota, now back in his human form. "The boos man knew that you'd use those eventually.", he mocked the two. "So he had me standing by to make sure you didn't."

"Why you.", Cobras hissed as he ran towards the ninja. "Give them back."

However, Darneko appeared from a shadow, knocking Cobras back with a slash of his claws. "You're open.", he commented.

"Plus, you left this unguarded.", Cha-ChaMari noted as she grabbed the canister of Dark-X. This and your Cosmo Spheres will be useful for Master Dark Soul's ambitions."

"Let's get to the meeting place.", Kota said as the rest of the aliens gathered near him. "Our grunts can deal with you." Then the aliens all teleported out, leaving the Rangers to fight off the Detainers.

Inside the structure, Dark Soul made his way through the guards, easily beating them in combat.

And in the main control room, Commander Goodman was finished. "There. The Base will self-destruct in 3 minutes, less than half the time it takes to program the self-destruct. Now then Pamela, let's go."

"I don't think so." Both women turned to see Dark Soul entering the room. "Pamela will be leaving here with me, I'm afraid."

"Not while I'm here.", Goodman insisted. "You'll have to go through me to get to her?"

"You?", Dark Soul laughed as he pushed Goodman to one side. "What can an old woman like you hope to do against me?"

"I wouldn't call myself 'old'.", Goodman said as she stood up, putting her Change Bracelet on. "In fact, I prefer 'experienced'."

"Wait.", Pamela said with confusion. "What're you -?"

Goodman pressed a button on the bracelet, saying "Let's Fly!" A wireframe formed around her, onto which her Ranger suit was deposited. "I've faced tougher opponents than you since your parents were in college.", she stated. "I saw my home destroyed on my watch, and when Gingaku invaded, I swore that I wouldn't allow that to happen to anyone again."

"A touching story.", Dark Soul stated. "But it won't save you from me. I'm shrouding myself in the darkness of the night." He transformed into Yamashi and summoned the swords Gingaku had used in his final battle. "Let's dance, lady."

Goodman and Yamashi thus clashed. Goodman pulled out her Wing Saber and delivered a swing to Yamashi, who blocked with his own weapons. She then pulled out her AviAttacker and aimed it.

Freeze Attack!

The weapon froze Yamashi, partially, but he managed to break out of it. "Didn't like that, huh?", Goodman asked. "Let's see how you like this. Sky Enforcer!" She summoned her gauntlet-like weapon, leaping backwards to fire a shot in Burst Mode, before leaping forward to hit him head on in Break Mode.

Outside the Base, the Rangers finished dealing with the Detainers. "That's the last of them.", Slash commented.

"Indeed.", Winda responded. "Now, we should move on to helping out inside Providence Base."

But before any of them could approach the structure, Providence Base exploded, sending rubble flying over the area. The Rangers were caught in the shockwave, taking a few seconds to recover. "What happened?", Jiro asked. "Where did that explosion come from?"

"The Commander must've activated the base's self-destruct.", Myron answered him. "I found out about it when I was working with Spectrum. Heath must've shown her how to set it."

"She gave her life to stop Dark Soul.", Drago lamented. "Not a bad way to go out."

"Don't kill me off just yet.", Goodman's voice echoed. Everyone turned to the rubble, where they saw her climbing out of the rubble, her Ranger suit damaged. "The suit absorbed most of the blast. They always said it was highly resistant, but I never knew just how resistant it was."

"Good to see you're okay, Commander.", Yuri said to her. "But what about Pam? Where is she?"

Goodman shook her head. "I'm sorry Yuri, but Dark Soul turned into a monster. I was no match for him. He took her."

Yuri fumed. "That creep. If I knew how to find him, I'd tear him apart myself."

"I think I can help you with that.", Myron said as he brought out the Cosmo Sphere detector. "He took Leo-77 and the Void Sphere. If I just input the basic energy readings for one of them…" He pressed a series of buttons and was greeted by a ping from the machine. "Got it. It's at a quarry not far from here."

"And where Leo-77 is, Dark Soul is likely to be as well.", Cobras repeated.

"We should set off right away.", Drago stated. "Rangers, move out."

"Okay." The Rangers all set off at a fast pace, except for Myron who was stopped by Scales.

"I've got something I need your help with.", Scales said.

At the quarry, Dark Soul had revived the entirety of the Gingaku members faced by the Rangers, save for Gingaku himself and Cerebron. "All is prepared.", Dark Soul stated. "Soon, I will be the ultimate power in the universe."

"Why?", Pamela asked him, from her restraints. "Why go ahead with this madness? You're not like this, Greg."

"'Greg' is long gone.", Dark Soul yelled. "I am now Dark Soul. The Red Ranger said so himself."

"You see, I don't think that's entirely true.", Pamela stated. "Yuri may not have any memories of you, but I do." Dark Soul hesitated, surprised to hear that Yuri had lost his memories. "You could've killed me yourself, but you didn't. That proves there's some part of you that still cares for me."

"Can we shut her up?", Kota asked, as he transformed into Diskus. "She's getting annoying."

Dark Soul was snapped out of his thoughts. "You know nothing of me. My ascension is still at hand."

"Sorry to disappoint you." Everyone looked up to see the 12 Rangers standing above him on the cliff, all holding their Cosmo Spheres (Yuri was holding his Big Bang Sphere). "But we're about to put the kibosh on your ambitions.", Yuri continued.

"You're too late.", Dark Soul shouted. "Thanks to the Cosmo Spheres I stole from you, the energy extracted from those Legendary Rangers and these combatants, I will become the ultimate life form." Energy flowed from the canister into the two Cosmo Spheres, which were held in his hands. Everyone in the quarry, including Pamela, was dragged in by the energy, with only Diskus being able to pull out, albeit reverted to his humanoid form of Kota, who ran out of the scene. "I'm shrouding myself in the ultimate power!" In a flash of purple light, there was no one figure in the quarry. It resembled Yamashi, but now had an elaborate mask that covered his face and circled around his head, also possessing a pair of horns and a golden star in the centre. He also had a large ring on his back, resembling a snake eating its tail. When he spoke, it was with Dark Soul's voice, amplified and deepened dramatically. "Now, I am Daiyamsashi!"

"So, you've got a new look.", Mila commented. "It's not a good one on you."

"I remember Gingaku took on a similar visage.", Proton stated. "Right before we took him down."

"Alright.", Yuri said, pressing the top of his Big Bang Sphere, as the others slid their Cosmo Spheres into position. "It's Morphing Time!"

Myron, Jiro, Scales, Tarrant, Cobras, Mila, Winda, Slash and Barry inserted their Cosmo Spheres into their Morphers. "Cosmic Energy, Unleash!" They then pulled their triggers.

Drago inserted his Cosmo Sphere into his Dragon Staff. "Charge Up!" He slammed the staff on the ground.

Proton summoned his Galaxy Saber and inserted his Cosmo Sphere. "Set!" He then began charging it. "Rise!" He then pulled the sword out. "Change!"

Finally, Yuri inserted his Big Bang Sphere into his Morpher. "Big Bang Energy, Unleash!" He pressed the top and spun the wheel.

In an instant, all twelve Rangers were Morphed. "Pfft.", Daiyamashi stated, summoning Gingaku's swords. "This won't even be a challenge." He ran into battle, facing Jiro, Myron, Slash and Tarrant. He took a hit from Jiro's Cosmo Claw and then delivered a slash to all of them, knocking them away. He then fired a beam at Cobras, Winda, Drago and Scales, who dodged the explosion and fired at him with their weapons. He absorbed the shots and redirected them to the other Rangers, before facing Barry, Mila and Proton. He slashed them away as well.

"It's me you're after, Daiyamashi.", Yuri stated, before delivering a slash with his Cosmo Saber.

"Don't ignore us.", Slash said, brandishing his Cosmo Dagger and running towards Daiyamashi, locking blades briefly before slashing him.

"Yuri's problems are our problems.", Jiro called out as he leapt forward and delivered another hit with his Cosmo Claw, knocking Daiyamashi back to where Drago and Winda could get a clear shot.

"Yuri's helped a lot of people as a Ranger, including Winda here.", Drago stated.

"Including me, the 'defective android'.", Winda exclaimed.

"He helped bring me closer to the others.", Barry stated as he slashed at Daiyamashi with his Cosmonata, before delivering a few thrusts.

Daiyamashi then got hit with Tarrant's Axe. "Myron, over to you.", he called out as he threw the enemy over his head.

"Double Sting Break!" Myron hit Daiyamashi with his horn arm.

Cobras then placed his Serpent-06 Sphere on his Cosmo Scythe. "I'll want my Void Sphere back when I'm done with you.", he stated.

"You mean when WE'RE done with him.", Scales called out as he leapt in to the fray with his Cosmo Rifle. The two delivered simultaneous hits to Daiyamashi, causing him to be surrounded by flames.

"I'm in on this too.", Mila called out as she leapt in with her Cosmo Blade.

"Oh no you don't.", Daiyamashi used his swords to try and cut through Mila, only for her to disappear. "What?"

"Never underestimate a ninja.", Mila stated. "Especially one with a Double-25 Cosmo Sphere." She appeared behind Daiyamashi and began fighting him with their swords, a fight that Mila won with a well timed hit.

"You're going down.", Proton stated as he rapidly slashed at Daiyamashi with his Galaxy Saber, causing him to begin to explode. "Yuri, go for it."

Yuri leapt up, bringing his Saber down with him. "Leo Lion Slash!" He delivered a series of hits to Daiyamashi, knocking him back and causing him to spark.

However, the Dark-X in his body caused Daiyamashi to rapidly heal his wounds, much to everyone's shock. "That's not all I can do fools.", he growled, sending a pair of slashes towards the Rangers, surrounding them with smoke.

"Dark Soul's becomes really strong, maybe even stronger than Gingaku used to be.", Kota noted. "It'll be hard for the Rangers to get out of this."

The Rangers reeled from the blast on the ground. "He's strong.", Proton stated.

"I'm feeling a lot of pain.", Cobras added.

"But we have to keep going.", Proton stated. "It's the only way to defeat him."

"That's right.", Drago replied.

"Let's do it.", Scales added. "We're the last hope of stopping him."

Daiyamashi laughed. "Your full power is no match for me. I am as strong as Gingaku. No, I am stronger than Gingaku." He surrounded himself with energy, growing to a giant size that was much bigger than the norm. "Now, face my true power!"

"Let's go.", Yuri stated, reverting to his Red Ranger form. "It's now or never."

"And never ain't looking good as an option.", Jiro responded.

"Let's do this.", Proton stepped forward with the All Zords Sphere, which he inserted into his Galaxy Saber. "All Zords, combine!"

The twelve Cosmo Spheres came together using the Lion Zord and the Fire Voyager as a base. "Zodiac Megazord, ready!"

"Let's finish this.", Yuri said.

"Right here, right now.", Proton added.

"Arms ready!", Slash, Winda, Mila and Myron radioed.

"Legs ready!", Tarrant, Scales, Jiro and Cobras radioed.

"Upper body ready!", Drago and Barry radioed.

"All systems aren't go.", Yuri stated.

"That won't help you.", Daiyamashi's voice echoed. He surrounded himself with the Dark-X. "You're no match for my power." He summoned a ball of energy, firing it at the Zodiac, buffeting it.

"We're barely holding together.", Yuri panicked. "Return fire." He launched a beam of yellow energy back at Daiyamashi, with the two locking with each other, though Daiyamashi's was more powerful, eventually pushing the Zodiac back.

Everyone was buffeted from inside the Zodiac, but they pressed on. The Zodiac stood its ground as Daiyamashi continued his onslaught. Eventually, the Dark aura surrounding them cracked. "He's weakening.", Proton stated. "Nows our chance."

"Right.", Yuri replied as he led everyone else in pushing forward. As they did so, the stars themselves that had chosen the Rangers and given their lights to create the Cosmo Spheres glowed, channelling their powers into the Zodiac.

"What's this?", Slash asked.

"It looks good.", Mila replied.

"The stars are with us.", Cobras realised.

As they continued to glow, Daiyamashi was weakened further. "No, it can't be.", he stated, as the Megazord broke free of his blast.

"It's the Cosmo Spheres.", Yuri realised. "They can sense the plight we're in and are giving us their power."

"Let's use it.", Proton urged.

Everyone prepared the final attack. "This is it, people.", Myron stated. "The end of Gingaku's last member and by extension, their threat."

"Our Power is one with the stars themselves.", Yuri stated, as the symbols on their 12 Cosmo Spheres appeared behind them.

"Cosmic Energy Abreaction!" The Rangers fired their beams at Daiyamashi in the form of their Zords.

"This can't be.", Daiyamashi growled. "I'm the ultimate. I can't lose." He then exploded, restoring the sky to normal as the Megazord stood tall.

Pamela fell out and landed on the edge of the quarry, the Leo-77 and Void Spheres next to her.

On the ground, Daiyamashi lay down as the Rangers approached. The energy that Daiyamashi had absorbed from the Dark-X and Gingaku was released into the sky, dispersing throughout the universe, as he reverted to Yamashi. "The power's gone.", Myron noted. "The energy stolen from the Legendary Rangers has returned to the Morphing Grid, while the powers of those Gingaku goons is gone forever."

"What?" Kota had a realisation. He tried transforming back into Diskus, but realised he couldn't. He was now stuck in his human form.

"Well, what're you waiting for?", Yamashi asked Yuri. "Pull your trigger. Finish it."

"It's like, you said, Yamashi.", Yuri stated as he took his Big Bang Sphere out of his Morpher, powering down in the process. "You were my friend." Everyone else powered down as well. "And while I may not remember our time together, I'm going to try and help you remember our time together."

Everyone seemed touched by this choice, even Pamela from the sidelines. "Yuri.", she said quietly.

However, Proton ignored this moment, instead pushing through the others. "The Dark-X is mine.", he said in a monotone.

"I'm sorry?", Mila said with confusion.

"The Dark-X is mine.", Proton stressed as he pushed Yuri aside, approaching Yamashi and placing his hand on him.

"Proton, what're you doing?", Yuri asked. "Kyle, speak to me."

Dark-X flowed out of Yamashi, reverting him to his human self. "I have succeeded.", Proton, who was clearly not himself anymore said with an almost sadistic glee. "Contact has been made!" The other Rangers reacted with horror to this, as purple smoke surrounded the possessed Fire Knight.

As the smoke cleared, Proton was gone. In his place, there was demonic looking being, with an exposed brain on his head and chest, large demonic wings with red and black patterns on them, wearing a red overcoat. "Gingaku.", Winda recognised him from her trip to the past on Tempus.

"How nice of you to remember me.", he commented. "I've been reborn in the body of my old enemy." He then summoned up a ball of energy. "But in order to be the ultimate life form, I need to absorb your energy as well." He then launched the ball at the other Rangers.

"Oh no you don't.", Drago exclaimed as he moved to block the ball. "Don't worry about me.", he called to the others. "Just get out of here. Now!" He was then absorbed by the ball, which retreated into Gingaku's new body.

"He was delicious.", Gingaku commented. "And all of you are next."
