In Cyber Dream...

"Is this a dream world, or a cyberspace?" The 12th Doctor have no idea. "I never seen this kind of atmosphere before."

"Hmmm... How about we hop around-" The 11th was interrupted byCream.

"Mr. Eleven, this is dangerous! This world is filled with hazards!" Cream warned the Doctors.

Meanwhile, Eleonore actually wowed over Ryuumei. In return, the sorceress is amazed at the flame of the Rubedo - makes sense, since they're both the same person."

"Hey! Rubedo, we gotta move on!" Shirou walked out.

Eleonore, being disdainful to all other than LDO and Ryuusui and Ryuumei (due to the loyalty of her with Reinhard), tsk'ed. The two flames then moved forward anyways.

"Miss Nicole, you're not even powerful enough by yourself." Sage, noting Nicole is nowhere near as powerful. "Stay with me, bring Sally."

"Who are you?" Archie!Sonic have no idea.

"Sage." Said the cyber-child.

"Sage?" Archie!Knuckles have no idea.

"My daughter. Cut to the chase." Eggman floating. "And if you're asking me, I'm floating because I have computers that... uh..."

Ariem squinted.

"Yeah, sorry..." Eggman cringed, much to Cream's shock.

"Don't scare her. She's an innocent child." Amy defended Cream. "We didn't forget how you used her to get into the Reverie."

The landscape is apocalyptic, with all the scenery in rubbles, seemingly from several worlds. above in the 360-degree skies are rifts, decaying. The Doctors, being the genius they are, looked around for suspicious landmarks and POIs.

"What is this?" Mighty and Ray saw a VOCS-branded payphone. "Maybe we should-"

"Sorry, but we're on the road." Knuckles pulled.

"I recognize some of those stuffs..." The War Doctor saw some familiar mutation. "NanoSeattle. Those angelic fogs. Orbital stuffs flying around."

"Mallory... where are you?" The 11th Doctor have mourned.

The unified army saw something... strange. A Genesis Portal leading to something...

"Look! Over there!" The 3rd Doctor pointed it out. "We have a potential critical point!"

"Don't enter!" The voice of Kado Thorne. "The Genesis Portal leads straight to the Last Stop! Erases your memory!"

"Thorne! I thought you left us!" Infinite noticed. "Uh... I think?"

"I hopped into the machine to get into Hypertime. I got into the shard, and stole other version. With Chrono-Cell fully charged, and my memories intact, I got back to work." Kado explained. "With the time machine i have, not only multiple variants of the Island are travellable freely, from past to future, and in-between, it also allow me to access Hypertime, and let me borrow another machine, so to hide from Team Shatter."

"And how did you contact us across?" Sonic is confused. "You didn't show up here, and yet you still can speak!"

"Alaya. Collective unconsciousness of humanity and the source of Kantan multiverse. That multiverse, with its own metaphysical existences, ideal incarnates, embodying countless possibilities of the future, indexes for all humans' dreams." Kado continued. "The resident true reality warpers are known as the Rosei, who shedded their original physical body and reached Alaya, to gain dream powers, similar to Dreamweave. They have Tsuidan, basically all the abilities without human limitations."

"You're saying the Alaya is dumped into the unified world as well?" Ariem is shocked.

"Most likely. Here, because of all the noises from the Hyper Genesis Wave that caused the merge. Now I can sense all the worlds dumped into the unified world." Kado continued. "The rift power bypasses the dream world, and affects the Alaya itself when used accordingly. I'm using Alaya to try and contact you, and seems like it worked."

"So somebody dropped an Unity engine to a world then." Twelve figured it out.

"I found a few in what Kantan got dumped into. Those Unity Engines are the mass-produced ones." Kado then realized what the Doctor suggested. "Wait... Unity Engine?"

The Doctors told the flashbacks of Wave and the sorceress (Eleonore/Ryuumei).

"I knew it." Kado got it. "That evil hedgehog sure is depraved."

"He became depraved because..." Sonic explained Shatter's backstory and rise.

"This is definitely something to watch out for." Kado called. "Anyways, avoid that portal. It leads to the Last Stop, and that would erase all your memories if you enter."

"Fine!" Robotnik groaned. "Let's keep walking!"

The unified army avoided the Genesis Portal, and carried on. A while later...

"Urgh..." A fashionista beaten up. "Help..."

She has burning hair with ponytail, and a tattered white leather jacket. She's also glitching, as if being affected by cyber-corruption.

"No... Mrs. Spark! No!" The 2nd Doctor rushed for help.

"Please, don't rush!" The 13th Doctor chased.

"C'mon!" Rusalka whacked her shadow, and pulled Thirteen off. "This girl needs help!"

Suddenly, a pinkie has tele-blitzed to the scene, and kicked the 2nd in his face.

"Oh no!" The Doctors gasped.

"Found you. And you too! And you too!" She chocked Spark, who's clearly on the fritz. "The last of Netwerk... Not so powerful, aren't you?"

"What... have you... done?" Two got back up.

"Hey, you!" The 14th Doctor called her out.

"This is my world. My dream. my place." She smirked, and then destroyed Spark.

The pro gamer and streamer action screamed in agony, as her spftware is being destroyed by sheer cyber-corruption. A malware that breaks completely. And as a result, Spark's avatar has been annihilated. Spark is dead. That was game over...

"Netwerk no more. The last survivor is dead." That pink one... "Good riddance."

"Nightmare Rose!" Sonic recognized her.

"You just destroyed a software... Wait... no..." Thirteen realized what's up.

"Oh... oh! So you've caught on? Netwerk's finally extinct. All those pesky 'wares have all been exterminated." Nightmare Rose floats down. "You all just saw the last survivor, Spark, die in my hands."

"How dare you!" War Doctor immediately whipped off and fired his Sonic Screwdriver on the Dragon Quarter.

It didn't work.

"A puny sonic blaster." Nightmare Rose scoffed. "Oh... finally! There's the Doctor!"

"Why the singular? There's more than one!" The 9th Doctor wagged.

"Nope." Nightmare Rose kicked Two back to the army. "Just the variations."

"Bruh!" Fourteen facepalmed.

Nightmare Rose thinks the same person (the Doctor) is appearing multiple times in the same plane and scene. Also, she struck the 6th Doctor with her own axe, but thankfully using the blunt end.

"How dare you!" Sonic went for a Spin Dash.

The power of Speed Force accelerated the Spin Dash, easily knocking the false Amy away.

"HiiiYAAAAA!" Amy herself swung down her evil alternate.

The Dragon Quarter is down on the ground. Amy was about to crush her, but the evil then, in anticipation, rolled out.

"Shoot!" The Heroes of Tomorrow had peeked out from the builds they created, and shot the nightmare who evaded by a spin.

She rammed a brick wall, knocking it off and destroying instantly, but the Suicide Squad caught on thanks to a boomerang borrowed from Sticks.

"Wanna try out Speed Force?" Captain Boomerang caught off Nightmare Rose while letting Sticks. "Mine is infused for you. Now go!"

Sticks picked up the boomerang of Harkness, and instantly vibrated on contact.

"Woaaah... Speed Force!" Then Sticks threw it, further slicing against the false Amy.

Captain Boomerang shotgunned Nightmare Rose, followed by a bat from Harley Quinn.

"Ugh!" Nightmare Rose recovered mid-air.

"Midgardr Volsunga Saga!" Michael ambushed.

A direct hit! The false Amy cracks down.

"Keep it down. Go!" Eleven, riding a guided missile, fired his Sonic Screwdriver to keep Nightmare Rose down.

The Nigredo, attempting to erase the false Amy from existence. However, Nightmare Rose, with the power of cybernetic nightmare, resisted, and...

"How!? You still have history! This should've erased that evil!" Michael realized it's not working. "My future, help me with this!"

"You think you're wiping fast enough?" Nightmare Rose dismissed, and straight out tried to escape.

The missile runs out of fuel, and Eleven jumped off. Just in time for...

"Midgardr Volsunga Saga."

Tenma Ootake jumped in, and punched on Nightmare Rose opposite to Michael. With the absolute-end-of-one powers exponentially amplified, the false Amy is cracked even more. Wolfgang Schreiber, riding in Niko alongside Teirei, chuckles at the sight.

"Alright. Mission accomplished!" Wolfgang himself thought the job is done.

"Phantom Ruby blessed me. You're only erasing an illusion." Nightmare Rose then disappeared.

Suddenly, both blacks fell down to the ground, face flat, much to the confusion of the unified army. Including Wolfgang.

"What?" Wolfgang is baffled. "How-"

Niko is knocked down by a kick, leading to the the three whites crashing down to the ground. That was by Nightmare Rose, in her dragon form.

"No!" The Doctors fired their SS'es to the Dragon Quarter, but no use.

"Stop it!" Rusty Rose bounced off to attack.

"Yaaaaar!" Black Rose rushed in.

"How dare you!" Thorn Rose hopped off her Birdie, and went for a crushing.

Nightmare Rose roundhouse off Rusty, and knocked Black Rose with a brutal whack, and then blocked the hammer.

"No!" Amy is shocked.

"Help-" Thorn got chucked.

"How is it like to be buried in defeat?" The false Amy stomped Thorn down.

Rusty hit Nightmare with her blaster, which only perturbed the latter. The evil alternate tele-picked up her axe, which sliced off Knight Arthur's armor in the process.

"Seriously!?" Knight Arthur is baffled, as he picked up the pieces of his armor that just saved him from decapication.

A few World Warriors standing up got hit by the handle, tripped down as if fighting game, hitboxes and all.

"Hmph. What a scrap." Nightmare Rose raised her axe.

The Zeti immediately fired their technopathy to distract the false Amy, followed by Infinite throwing the phantom cubes to her.

"She's doomed. You'll be." Nightmare Rose bludgeoned the cubes while just walking.

"Fuck you!" Nicole had enough.

The holo-lynx and Sage pushed the glitch to Nightmare Rose, stalling the latter down. This gave Rusty the time to recover, as well as the rest of the Shatter-verse army to riot.

"Arrrrr! You're not welcome!" Knuckles the Dread struck the false Amy.

She fended off them quickly, but that was the moment to distract her, allowing Sonic to deep dive the Speed Force.

-*cracks* And the moment it is, because Sonic went for a Spin Dash, and cracked the back of the false Amy.

"Oh yeah!" Sonic laughed in excitement.

The Dragon Quarter is knocked to the rubbles, detransformed.

"Odjn... We finish her!" Ryu-5 D-Dived, and performed D-Breath.

"Super Double! Haaaaah!" Mega Man and X powered up and accessed Super State (Double Gear) and Ultimate Armor, respectively.

The three blasted the false Amy, causing a massive explosion that cleared all the nearby rubbles and nearly reached the land where the unified army stays. And furthermore, to ensure she's dead, the Observers went for necessary overkill. Shirou and Judas chained the blast center (where Nightmare Rose got hit and blasted), and...

"Magic Bullet..." Zurvan and Judas cocked.

"Malignant Tumor Apoptosis!" Shirou and Sukuna yelled.

The Observers pull the triggers... *massive synchronized gunshot* A flash finishes off the explosion...

"Again!" Ryu-5 resumed the D-Breath.

The three shot again, and it leads to an even larger explosion, which knocked the seven off and briefly blinded off the army.

The scenery glitched, and the whole thing subdued. Everyone recovered, and Ryu-5 detransformed to avoid risk from D-Counter.

"Finally..." Wolfgang sighed. "Why this overkill?"

"Overkill? More like necessary overkill." Shirou chuckled. "Right, Ellie?"

"Oh, so you're suggesting this nightmarish rascal can regenerate, huh?" Ellie cringed.

"Rascal? Or so hedgehog? Is that me?" Classic Amy is confused at Ellie, because the former is a rascal and her future is a hedgehog.

"She's dead. The false one is dead." Shahra stepped out. "Congratulations, Mas-"

"Don't call me 'Master'. I'm your friend." Sonic chuckled.

"Nightmare Rose, destroyed." Deadshot then left the scene. "Let's go. Make the most out of our dreaming."

"You sure?" Ariem called.

"Why didn't you get into action?" Deadshot looked back.

"I'm trying to rebuild the Reverie." Ariem turns out to be scrambling. "C'mon! I need to Dreamweave this place! Fix the-"

"It's utterly broken!" Kiryu refuted. "You cannot restore this place alone! You're not powerful enough by yourself, and even our emanation options are still limited!"

"He's right." Silver shaked his head. "Dreamweaver, we should get going."

Ariem sighed, and stopped trying.

"Also, your body is screwed. Maybe with the help of the emanators, we can fix your body." Eggman suggested. "Heck, even tame the Guardian Hunter."

"You Doctor Robotnik, sure, thanks." Ariem then moved. "But I won't forget about what you have done to the Reverie."

Suddenly, the whole area and even the whole landscape quaked. The unified army can feel the literal shaking.

"What's going on!?" Habaki noticed.

"This place... It's falling apart!" Twelve looked around. "Even though it's the cyber-space and the dreams!"

"This is no good! We must escape!" Nine looked up. "The sky's breaking apart! It's decaying!"

"Just like the Shatterspaces..." Nine then moved on. "We have to run!"

"Yeah, right. You have to run!" Kado called. "Nightmare Rose is dead. So now the Cyber-Dream falls apart."

"Huh? Wait... it worked?" Tenma Sukuna caught on. "Wait... we destroyed her?"

"We blasted her after she's knocked out and detransformed." Ryu-5 shrugged. "So what?"

"So y'all have finally killed Nightmare Rose. She isn't just a Dragon Quarter... She's a Rosei too." Kado continued. "That activated Forced Cooperation. The condition there was for you to kill her. Also, the fact that Kantan is part of Cyber Dream means that you'd truly die in waking world if you got killed here."

"Wow. So glad we all survived." Nicole is surprised.

"Oh, and because she can manipulate nightmare... she's the ultimate Rosei. Her Tsuidan, which has just activated because you killed her... oh no, she has the abilities of all of the Rosei ever existed!" Kado freaked out. "The Forced Cooperation she had is wired to mister Amakasu Masahiko's Tsuidan: Ragnarok!"
