"Found you!" Grim Shadow intervened. "You freed some of the dangerous being and devices we confisicated. More troubles from you that I must fix- wait... You knocked down the fellow three!?"

"I'm taking my body back." Ghost Shadow confronted Grim Shadow. "So fuck off!"

The robot then attacked with full force, emitting Chaos energy to overwhelm the unified army all at once. This started burning the members, especially weaker ones without much resistance of. Habaki's healing has however, already bestowed through Rindou and the Tai-Aztiluth, actually kept the damage off.

"Chaos Control!" Grim Shadow blasted the area off in an attempt to kill and/or K. the unified army.

"Holy shit! Chaos here!" Sonic reacted by taking his Chaos Emerald.

The Chaos burst is warded off, saving the army. He went Spin Dash to Grim Shadow, knocking the robot off. And then again to kick it out of the castle.

"Sonic! Are you sure you can last?" Knuckles called.

"How many rings do you have left?" Tails called.

The super-hedgehog picked up Blue Star, and off. "I'm fine! The Speed Force suspends the state, so I can keep it indefinitely! I'm afraid you'll need a lot of rings though."

He jumped out, and rides to Grim Shadow, who rebounded and flew at high speed. Thankfully, the Extreme Gear make it much easier to keep up, especially helped by the Chaos power making him faster.

"HAAAHHH!" Sonic did a Gravity Dive, clashing with the robot.

"Everyone! Get your stuffs!" Rindou yelled.

"Can we ride narrowly through?" Knuckles staging the Red Rock, his board.

"UGH..." Chip almost vomited.

"How dare you!" Sonic crashed the robot.

Grim Shadow bursted, whacking Sonic off. He lands at speed, and jumped off from the same ground the unified army sneaked few days ago.

"Take this!" Sonic rushed to the robot, countering its burst.

Grim Shadow viciously responded without speaking, burning Sonic with Chaos force. Sonic, being Super Sonic right now, went head-to-head, and Spin Dashes from his board and bounced like a classic video game of breaking bricks, capping off by a Gravity Dive.

"I'm... filled with... Argh!" Chip jerked out.

"What's happening!?" Robotnik panicked.

"The Dark Gaia..." Chip's voice suddenly echoed. "I've become..."

"Holy crap!" Sukuna is baffled. "Two problems in one! Which one should I worry?"

"Worry about Gaia. Yah cannot depower the Grim ones so easily." IDW!Bunnie called. "Ah know what to feel. Just... ah, nevermind, just watch out."

This response left the Apostasis/Apoptosis confused. "What?"

"You will be destroyed! We'll scrap you!" Sonic grinded off Grim Shadow, before returning to Blue Star.

Grim Shadow, still flying, used Chaos burst down to Sonic, but he evaded. This results in the ground being burnt and crashed.

"Fuck off!" Sonic pulled a Cycloop through the Gear - a combination of two tricks he know.

Grim Shadow is stunned, but Sonic threw Blue Star to crash the robot. He then Spin Dashes on the robot down the ground, before bursting up to take the board.

"Let's end this!" Sonic performed a Gravity Dive and simultaneously jumped to a Spin Dash. "DESTROYYYED!"

The Blue Blur in Super state crashed down to the robot, causing a large Chaos explosion. The fight was noticed by nearby Roboticized Masters, who were processing the remains of the victims outside the castle.

"What the fuck?"

The robots flew to the scene. Meanwhile, Chip grew in size, becoming a messy but clearly mobian-like creature similar in size to Sonic. His eyes changed to resemble each of that of Perfect Dark Gaia's own green ones. His wings became larger and more ornate, gaining iridescent colors and more grotesque, partially framed by tentacles resembling Dark Gaia's. And of course, the transformation is horrific, a nauseating sight. He's now vaguely resembling Mephiles's Shadow form or the Null, in shape but with wings.

"Crap! Disgusting!" Eggman threw up. "What's this!?"

"Urgh..." Sonic floated up, returning to the area.

"What the fuck!?" The Roboticized Masters found out.

Sonic simply blasted them away, and fortunately, the Masters cannot handle the sheer Chaos energy. The animal friends are left.

"Guys, I think I'm done with this. Let's continue-" Then Sonic stopped. "Huh?"

"Not... so... fast..." Grim Shadow got up, its visor cracked.

Cue a massive wave of corrupted Chaos energy - the same as a Phantom Ruby - trying to put Sonic down. The Avatar can hear that, so they went outside and protected Sonic with illusions.

"Oh, hey... Phantom Ruby?" Sonic squinted.

The Avatar nodded, and then hi-fives the Blue Blur.

"DIEEEEE!" Grim Shadow bursted to the brim, release pure corrupted Chaos onto the surroundings in an attempt to overpower and kill both. "CHAOS CONTROL!"

"I learned from Sally and Nicole that the Phantom Ruby is a stripped version of a Master Emerald from a lost world. It's what left of Master one, filled with corrupted Chaos energy, according to Sage." Sonic recalled. "Lunchtime does allow for discussions that're as revelatory as this."

Sage heard it, and is proud of this moment. But she has to tend the transformed Chip.

"Alright... Let's Chaos Control!" Sonic bumped with the Avatar.

Classic Sonic joined in. using his own Chaos Emerald to become Classic Super Sonic, burning through some rings in the process. He rides his Extreme Gear, the Blue Star II (which has higher speed but worse turning than the original used by Sonic), and then dropped to assist.

"Oh, little guy! Wanna go too?" Sonic called his past self.

"DIEEEEE!" Grim Shadow went full force, burning over the 200 metres of height.

"Uh oh. I feel the Chaos's heating this place..." Knuckles complained. "Holy crap!"

The Team Superstars looked down, and is greeted with radiative heating coming from the Chaos force. "Sonic! Rookie!"

"Chaos Control!" The three bursted, countering the Chaos burst from the Grim Shadow.

The robot struggled to maintain throughput, but there's the follow Spin Dashes from all three, alternating each of that and more Chaos Control.

"Ugh..." Tangle woke up. "Where... am... I..."

"Uhhh..." Whisper woke up. "It's... warm?"

"Chaos Control!" The three volleys down with Spin Dash.

"Urgh...!" Grim Shadow took the full force, but continued to tank and burst.

The three responded by speeding up the Spin Dashes, aided by the Speed Force which modern Sonic now shares with.

"Oh my god... They're exerting!" Merlina is shocked.

"Ugh..." Chip is fuzzy after the transformation.

"The burst's kicking us on the back!" Sonic realized. "Change directions!"

The three went into all directions to burst on all side and Spin Dash. Grim Shadow is seriously damaged, and stuck in the ground. Realizing the latter, Sukuna finally got an idea.

"Alright! Apoptosis's Destrucivity!" Yes, that's his Extreme Gear.

"Huh? Apostasis? Apoptosis?" Boom!Sonic finally realized something's strange. "Why are we and even the author are misspelling this?"

Boom!Sonic got ringed in his ears, causing him brief agony.

The word 'apoptosis' also suddenly gave the hedgehog and co. the location.

"What? Somebody said the true word!" Enerjak gets suspicious.

Sukuna rides down, taking some of the heat from the Chaps bursts. He aimed at the ground.

"Malignant Tumor Apoptosis!"/"Malignant Tumor Apostasis!" *gunshots*

The ground contacted with the Taikyoku, spreading the Aztiluth to Grim Shadow, who's standing in the ground. This messed up with the Chaos bursts, causing the robot to shake. The Spin Dashes now got to deal more damage.

"Nononononononononono-" Grim Shadow is struck down by the three.

"Boost! Boost time!" Sonic leapt alongside his two fellows, ready to finish off the robot.

And dash they go, blitzing to robot to the ground, creating an even bigger explosion, which reached even to the first floor's pillars.

"Holy shit!" Silver gasped.

Smoke rises up. The blast cleared out, and the three floated up and returned. This time, no other Roboticized Masters or any mook noticed in time. On the crater resulted from the explosion, a bunch of burnt scraps remained. Grim Shadow is destroyed.

"Oh wow! You did it!" Team Sonic allies cheered.

"Thanks me. Please, for I helped you with..." Sukuna rides up and showed his guns.

The three and the Apoptosis returned with their Extreme Gears back, and back to normal. The Avatar saw Classic Sonic tired - the latter has burned off a bunch of rings.

"Now... good..." Sonic then looked out, and he saw this grotesque form of Chip. "Chip!?"

"Sonic... I'm fused with... the Dark Gaia." Chip revealed why he's become this ugly mobian-noid.

Indeed, Chip has features of Dark Gaia in his larger, uglier body, which shook Sonic off.

"What are you now, Mr. Light Gaia?" Tokoyo/Theresia sighed.

"Dark Gaia can break a world apart. Light Gaia can reconstruct it back together. Well, over and over and over again..." Eggman recalled. "You see, since the beginning of time. Y'know, the time of awakening."

"Shattered World Crisis." Archie!Bunnie and Boom!Sticks in unison.

"Where are we?" Tangle brought Whisper up.

"Tangle! Whisper!" Sally and Nicole, through a single Gemerl copy, hugged the two. "You're back at waking world!"

"Sally... Nicole... everyone..." Whisper sobs. "Thank you...!"

"Awww, finally!" Amy responded.

"Urgh..." The remaining variants also woke up.

"Crap! That's my variants!" Ghost Shadow realized. "They're back! I can feel it!"

"Ahhh, so good to get back. I'm... Zombot again." Tangle looked at her hand. "You all rescued both of us."

"Corrupted Zombot..." Whisper remembered something. "That's it! They fed us with Metal Virus enhanced with Sigma Virus..."

"Sigma Virus alone already enhanced, now serving as miniature Unity Engines!" Nicole warned both.

Soon enough, the three variants came to the scene, and ambushed the girls four.

"Dah!" Tangle whacked Savage with her tail. "What the!?"

"You! What are you doing!?" Jones then suddenly realized. "No... no... you..."

"Huh? Tangle! Whisper!" Sonic finally noticed. "Oh no! Team Shadow!"

Agent Phantom went on and looked down. He's offended by the sight.

"Our grim friend!" Shad lashed out. "What have you done to him!?"

"Simple. We destroyed it because honestly, it deserves that." Sukuna scoffed. "He masterminded two bunnies' wrongful brawl! Now eat this!"

Sukuna unleashed his chains onto Shad before he could move. The cyborg just freed himself out by Spin Dash, but is knocked by Surge.

"Ugh! Another enemy!" Surge blurted at the variant, much to his chargin.

"You arrogant escapist!" Shad attacked Surge, forcing her and Kit to take the fight.

"We don't have the Paradox Prism!" Eggman complained. "What do we do!?"

A shapeshifter in form of Reinhard is in the shadows, wielding a modified Zapotron. Meanwhile, Jones and Savage both attack Tangle and Whisper and the robo-Gemerl, Shad go against the Starline duo, and the three are enraged.

"No!" Whisper using Green Hover mode to keep Savage at bay. "Tangle, watch out!"

Jones tried to cut the tail, but Tangle, with her athletism, evaded the drowned pirate, before whacking him off.

"Let me try it out..." Chip suggested, and then focused on Shad.

"I may be wet by you, but you are mere weather bullshit!" Shad tries to kill Kit.

"LEAVE HIM ALONE!" Surge bursted, trying to electrocute Agent Phantom.

Then Shad is blasted by Chip, using the Dark Gaia bbeam of energy. This once again defeated the Black Chaos, knocking him unconscious.

"Holy shit! It's... a fusion of light and dark! The ultimate Gaia!" Jones finally noticed.

"Oh really?" Chip ruthlessly turned back.

The two evil variants tried to escape, but got blasted just before they can Chaos Control.

"Black Chaos. The Wild. Deep Doom. Done." Chip phews.

"You're so powerful." Vector gasped. "Two primodial creatures now fused into one specimen! Unbelievable!"

"Finally! Got an use to this zapper!" Reinhard's impostor arrived, wielding a modified Zapotron with a mini-prism of rainbow attached in the gun. They imitated the real Mephistopheles's voice. "Stand aside! The man's coming!"

The impostor, like a genuine Deus ex Machina, zapped the three variants alongside Ghost Shadow, dumping them together in air. A ray of Prismatic energy blasted the variants, and cue the white blinding light.

"Shura!?" Rindou averted her vision.

The flash subdued, and a Shadow lies down on the floor.

"I knew it! This was really useful, after all!" The imposter let out an almost-childish laugh, dropping Reinhard's voice.

"Huh?" Rindou is confused.

"What?" Ootake/Machina is baffled. "Who are you really?"

"Look!" Boom!Sonic pointed it out.

Prime!Shadow, unconscious but very much alive.

"SHADOW!" Prime!Rouge hugged her own Shadow. "I've missed you!"

"The Shadow protocol is no more." The impostor spoke with that one voice, then laughed with Reinhard's voice.

"OMG! He's back!" The Shatter guys came to get Prime!Shadow.

Nine then looked at the impostor, holding the modded Zapotron. The New Yoke Tails gave them a thumb-up.

"Good. We've saved a life." Chip, still haven't decided the name of this form yet. "Thank you, stranger. May I ask you where are you from?"

"We did it! We caught the variants and got the Prime World's Shadow back!" The Gemerl copy celebrated.

The impostor simply looked on the robot, much to the duos' weird out. Then they shot the robot, destroying it.

"Hey! Not fair!" Tangle objected.

All the cheering and celebration stopped, and the unified army looks at the impostor awkwardly.

"Why did you blast the hijacked 'Gemerl' off?" Tokoyo/Theresia questioned the impostor.

"I would've joked about this, but I have no choice!" The impostor replied. "This robot is dangerous!"

"Why?" Whisper didn't buy it. "The friends completely hacked that robot. It helped us with the combat."

"This robot is designed for combat? Well, you know what?" The impostor called. "That robot would be hijacked by the corrupted Dreamweaver!"

The unified gasped in shock.

"Ariem the Dreamweaver, you may ask?" The impostor revealed. "She's finally been corrupted. I know this because I was one of the captives for Nightmare Rose, freed by others a while ago!"

"Ariem... No..." Sonic is horrified. "What have..."

"Because the ritual was prevented in the long run, Team Shatter had to improvise."
