"Knuckles!"

The loud call of his name has startled the Guardian of the Master Emerald right out of his sleep. Groggily, he sat up and blinked his eyes rapidly in the attempt to focus them, as he noticed that it was already late morning, and that somehow; a familiar white hedgehog currently floating towards him.

"... Silver?" he questioned drowsily, shaking off the sleepy state he was in. "What are you doing here? Didn't you go back to the future already…?"

"I have bad news! And I need your help!" replied the white hedgehog - panting - as he landed on the altar of Angel Island. "Do you-"

"Hang on, hang on; I'm not awake yet..." grumbled the red echidna as he stood up, taking in a few deep breaths while stretching his muscles. "... Tell me your story again, from the start."

"Well, after I've returned to my future after the time-eater incident," Silver began. "I saw that my world had been replaced by Eggmanland!"

"Wait; Eggmanland?" the new piece of information had completely snapped Knuckles awake. "How?"

"I don't know the details specifically, but Sonic was somehow defeated." replied the white hedgehog. "The Tails from that future had left me a message asking me to save them in Sunset Heights, tomorrow!"

"Sunset Heights, huh…?" Knuckles mumbled, lightly scratching his head. "... I don't really know specific places - you do know I don't live down there, right?"

Silver sighed - that was what he was afraid of.

In a sudden instant, both mobians found themselves being harshly pummelled onto the ground, and their bodies to become very, very wet.

Recovering from the shock, Knuckles pushed himself up from the ground, while his eyes widened at the recognition of exactly what had attacked them: Liquid, blue, and a weird, humanoid form creature.

It was Chaos!

What in the world was it doing here? It shouldn't be here!

"Look out!" shouted the red echidna, as he pushed the white hedgehog - who was attempting to get back on his feet - aside from another attack from the creature.

"What is that, Knuckles?" Silver inquired loudly as he stabilised himself, floating in the air using his psychokinesis.

"I'll explain later - aim for the brain!" ordered Knuckles, as he dived for a hit.

Since Chaos was being hostile - they had no choice but to take it down first; before it could do any harm. The creature had predicted the guardian's movements, and quickly dodged to the side; successfully avoiding the punch.

In retaliation, Chaos extended his arms, and attempted to grab a hold of the echidna.

However, Silver saw it. With quick, trained reactions of being a psychokinetic, the white hedgehog stopped the monster's liquid arms in mid-swing; and a bright, cyan glow surrounded the creature, holding it firmly in place.

"Now, Knuckles!"

The call to action was answered instantly, and Knuckles swung his right fist with all his strength, directly aimed the head of Chaos. It would take down the creature in a flash.

Except; it disappeared.

Knuckles blinked in confusion, as Silver stared; both mobians unsure of the current situation, or what exactly happened that caused Chaos to vanish.

"Where did it go?" asked the white hedgehog, as he frantically looked around in search of the liquid monster.

"I don't know; but let us leave before it comes back." Knuckles suggested, also wary of his surroundings due to the surprise attack moments before.

"But, we both don't know where exactly Sunset Heights is located!" reminded the psychokinetic hedgehog.

"Then, let's go find someone that could help us." he added before Silver could attempt to pull all of his own spines out of his head.

"Right!" Silver exclaimed optimistically.

Knuckles began to walk to the edge of the floating island, fully expecting the white hedgehog to follow him.

"Wait!" Silver stopped him before he could jump off the ledge. "Where are we going?"

"You said that Sonic will be defeated, right?" Knuckles responded with a question. "Whatever that did it must be really strong - so; we're going to find the Chaotix - they pack quite a punch."

And the red echidna led the white hedgehog to Green Hill after they jumped off of the floating island; with Knuckles gliding in the air, and Silver flying - thanks to his psychokinesis abilities.

The destination in mind was the Chaotix Detective Agency, and it was located specifically in Green Hill Town. It had taken quite some time to find their bearings due to Angel Island's constantly unknown position around Mobius.

Eventually, they did arrive at the location; it was a small building in the central areas of the bustling town.

They walked in.

"Welcome to Chaotix Detective Agency!" three voices shouted all at once, as Knuckles and Silver walked through the entrance.

And right after, a certain purple chameleon had immediately facepalmed - while, at the same time, avoiding being poked by the horn on his own head.

"Vector, why do you make us do this…?" groaned Espio, loudly, as he walked to a corner of the room to sulk.

He looked as if he wanted to just disappear for a moment.

"Why; to welcome new customers, of course!" replied Vector, cheerfully, as he turned to face the visitors. But, when he realised that the visitors weren't customers, his mood did indeed waver slightly. "Knuckles? Silver? What are you doing here?"

"Vector said there will only be discounts for new customers!" Charmy chimed in, pointing up an index finger.

"Quiet, Charmy!" hushed the crocodile; while at the same time, Espio finally felt brave enough of his recent humiliation, and turned to face the two visitors.

Knuckles sighed while he folded his arms - he really didn't want to deal with the Chaotix's antics right after waking up. Meanwhile, Silver the Hedgehog had taken a step forward, ready to share his story.

"Let me explain-" began the white hedgehog. "-Sonic's going to be defeated sometime tomorrow. We need all the help we can get in Sunset Heights Square!"

"You look tired, Silver." stated Espio, noticing the other's fatigue from their posture and movements. "Did you just come from the future?"

"Yes, that's right." the white hedgehog answered with a nod.

"If you wanna rest, we have a spare bunk that you can use." offered Vector, as he lightly scratched his head with one hand, while the other waved around to emphasise his speech.

"Breaking news alert!"

The sudden spoken words from the news station on the running television set - placed on top of a shelf - had caught the attention of everyone in the Chaotix Detective Agency.

"Doctor Eggman's forces are currently attacking City. There is a huge threat posed, and the authorities are suggesting that all citizens stay indoors until the situation is dealt with. Currently, Sonic the Hedgehog is resisting the attacks."

Wait…

"What date is it?" asked Silver frantically, as he looked for a calendar, or at least something that could tell him what he needed to know.

"February 5th!" Charmy provided the information.

Silver felt a sense of dread, followed by impending doom. No - it couldn't be; he was very sure that he definitely keyed in February 4th on his device!

Something had gone wrong…

"I don't know how, but somehow, I've been brought to the wrong date!" stated Silver, as his eyes looked more serious than ever. "We have to get there immediately!"

Espio's brows - if he had any - furrowed.

"I believe Charmy and I can follow you there first, since we have the speed." suggested the charmeleon, causing the white hedgehog to focus his attention on him.

"I'm going to need you guys to bring me there - I have no idea where Sunset Heights is." stated Silver honestly, as Espio began to lead them out of the establishment.

"Vector and I will try to catch up as fast as we can." added Knuckles.

And moments later, the Chaotix Detective Agency was closed.

Shadow the Hedgehog made his way to City as quickly as he could - at the speed of sound - with his skates bursting out flames through its thrusters; the scorching heat leaving a mark in the ground wherever he went.

In their haste, and their requirements for their mission to stop Eggman, Team Dark has decided to send Shadow - with his speed - to resist Eggman's attack in City; while Omega - due to circumstances - was sent to Sand Hill, in order to investigate Doctor Eggman's new identified base - huge, towering pyramids that somehow suddenly appeared several hours prior.

Concurrently, Rouge the Bat had stayed behind in G.U.N. Headquarters in order to supervise the operations; as she was good at planning, and partly because the other two could get to places quicker than she could - especially Shadow.

Time was a luxury that they didn't have in this emergency.

"Report in, Omega." Rouge instructed over their wrist communicators, as the black hedgehog continued his race from the G.U.N. Headquarters in Metropolis to City.

Omega should have reached his destination already - it was nearly three to four minutes since they've set off.

"Commencing extermination on Eggman robots." came a response from a robotic voice that Rouge and Shadow were quite familiar with.

"Extermination?" the female bat exclaimed incredulously. "You're supposed to be on recon! Stealth!"

"Concern not necessary. Eggman robots are being eliminated."

"I knew this was a bad idea..." commented Shadow regarding their robot teammate, as he closed in to City; his skates still running at full power. "And this doesn't look good, Rouge."

"What's the situation over there, Shadow?" asked the bat as she pulled up Shadow's coordinates on the radar.

"Parts of City are burning down." reported the black hedgehog as he chose the shortest route he could remember to City's centre: Sunset Heights.

"What?" Rouge couldn't believe it. Eggman had never managed to destroy a place that quickly before. This was a first - just what exactly is going on?

"Robots are being exterminated." came another report from E-123. "New enemy type detected. Data unavailable - could not identify."

"Is it a new type of robot?" inquired Rouge as she typed down the new information received. "No matter, just take it down, and hack into the doctor's computers."

"Subject is biological." came the reply. "Taking down target now."

Shadow frowned as he approached the vicinity of Sunset Heights.

Biological? Eggman had never dealt with anything living before - that was more of the scientist's grandfather, Gerald Robotnik's field of expertise. Just what was the fat man planning this time? Was this new biological weapon the reason of his long hiatus?

"It's not a robot?" questioned Rouge with some shock apparent in her voice. "Do not kill them, Omega!"

"Error: Position coordinates lost." Omega's robotic voice spoke through the intercom. "Current location unknown."

"Omega? Omega!" Rouge called. "Respond!"

There came no response.

While in his rush, Shadow had heard screams from people he passed by. The contents screamed by the civilians made him slightly confused.

"It's Shadow the Hedgehog! Run!"

What exactly was going on? People were afraid of him? It had took him quite some effort to clear his name the last time a similar situation had happened!

In this part of City, the black hedgehog could see even more instances of burning structures.

He huffed - right now, that was not the priority on his list. Shadow swiftly closed in on the source of explosions, and screaming that he could see and hear. He was very close to engaging the enemy forces; as he realised the place he was in was near the square, in Park Avenue.

"I can't get through to Omega, Shadow." reported Rouge with a sigh. She sounded stressed. "How's your situation?"

"I'm engaging enemy forces now." replied Shadow with his deep voice, as he jumped up a great height in the air and looked in the direction of the enemy swarm, ready to attack the Eggman robots.

It was time to take out the trash.

Rolling into a ball after aiming at the enemy, Shadow the Hedgehog spun his body rapidly, causing the momentum produced to propel himself forward; launching himself at the target enemy robot like a fired cannonball.

And the robot was instantly taken down - with a hole through its constructed metal body. Within the blink of an eye, most of the Egg Pawns in the vicinity had fallen to the moves of one Shadow the Hedgehog.

Landing once more on the ground, Shadow frowned, and his brows furrowed. He moved his eyes around, scanning the area as more Eggman robots approached. Why did he feel like something was still amiss?

"Error: Probe to parietal lobe detected." spoke Omega once more through the communicator. "Perception lost."

"Omega?" Rouge tried again, pushing up the robot's transmitter volume on the control panel. "Respond, Omega!"

"He can't hear us." Shadow deduced as he took down the remaining Eggman robots in the area. "Something's very wrong, Rouge."

"Unidentified system intrusion. Potential internal damage detected. Emergency shutdown initiated." reported E-123.

"He's down, Shadow." Rouge sighed loudly. "How's things for you?"

"All enemies down." Shadow replied as he landed on the ground after taking down the final enemy.

THUNK! - the sound of heavy, dense steel hitting the ground.

"Except me, Shadow the Hedgehog."

The named hedgehog's eyes widened, and he spun around after hearing the deep, ominous voice that loomed behind him.

He was greeted with the sight of a floating, black-furred, masked mobian with a head of long, white, flowing mane. The mobian was clearly male, and a purplish-red jewel was embedded in his chest. It was glowed a vicious, deep red.

He also saw Omega beneath him; broken, with sparks coming out of his damaged systems.

"Who are you?" asked Shadow with rage; he didn't particularly like the sight of his destroyed robot companion.

The unknown enemy took a breath before speaking.

"I am… Infinite…!"

The reply to Shadow's question came, together along with a burst of bright, red light that blinded the hedgehog's vision. Blinking in the effort to fight off the light pollution, he opened his eyes the first chance he got, and he noticed that his surroundings had changed:

Shadow the Hedgehog was no longer in City.
