FaithMcKoy: Sure! I don't mind doing PM's! I'm not very good at providing ideas, but I'm down for that!

Shadow's fist connected with Sonic's head, resulting in an explosion as both fell to the ground. Tikal gasped as she teleported herself and Knuckles out of the proximity of the blast.

The Ultimate Lifeform stood above Sonic, the hedgehog being knocked into the ground as blood pooled onto the ground. A vicious smirk spread across the corrupt hedgehog's muzzle as he stared into the sky above them. His head ached as he spat blood beside himself.

"Give me my powers back, faker." He said in an oddly calm manner, hands balling into fists.

"Give me my fucking powers back."

Sonic laughed weakly, looking at Shadow mockingly. "I'll use them better than you ever did." He said slowly, choking out more of the red fluid. "After all... I still beat you when you had this." After saying that, Sonic teleported a few feet away from him, rising to his feet. He spat on the ground, getting into a fighting position.

"Fight me if you want it so badly," Sonic said teasingly, summoning his sword. "And I'll kill you in minutes,"

Shadow growled, glaring at him. Knuckles walked over beside him. "I'll fight him too."

"I recommend you don't, echidna... unless you want to see some history."

"What...?" Before anything else could happen, Shadow charged towards Sonic in a burst of speed, jumping over the hedgehog and kicking him in the back of the head. He then kicked him upwards before leaping up and ax-kicking him back down to the floor. Sonic landed on his feet, grabbing Shadow's leg and pulling him down, slamming him into the ground.

Knuckles ran over before punching him in the face, uppercutting him as Shadow recovered. He spin dashed into Sonic, sending him into a large boulder nearby, creating a crater inside of it.

Tikal watched this in silence before looking towards Sonic. He slowly broke out of the rock, growling. Several cuts were visible on his torso due to the shards of rock digging into him from the impact. "Hah... what the hell did you even come to me for anyways, Faker?" Sonic said, ignoring the pain that came from his body.

"I..." Shadow trailed off, narrowing his eyes.

"Why am I the villain in all of this? I'm simply avenging a friend... my brother..."

"..." Shadow was quiet, clenching his fists. He looked down to the floor in silence, contemplating.

A grin formed on Sonic's muzzle as he steadily walked towards Tikal and Knuckles before pointing a clawed finger at Tikal. "You know this, wretch. Why don't you explain this?"

Knuckles growled, punching Sonic in rage. "WHAT THE HELL ARE YOU TALKING ABOUT?!" He roared as Sonic fell to the floor. A gash was on his forehead as blood gushed out of the wound.

He responded with a demonic laugh.

Suddenly, Knuckles recoiled in pain as he yelled, falling to the floor as he grasped his head in agony. Images flashed back and forth in his vision, each worse than the other.

"What did you do to him?!" Tikal said in fear, staring at the corrupt hedgehog.

"Oh, just a little history lesson..." He replied with a grin. "I figured he wanted to find out what really killed off the Echidnas."

Angel Island, Time Unknown

Tikal laid on the ground, weak. She looked up silently as several echidnas dropped dead, covered in their own blood. Their eyes were rolled back, pupilless.

She saw 3 echidnas run-up to a hedgehog, daggers in hand as they prepared to strike him. The hedgehog's tail elongated, impaling all three as they gasped, one still trying to stab the hedgehog as he choked blood.

Tikal's eyes widened as she struggled to get up, blood pooling beneath her. She got onto her feet, looking up at the podium that the hedgehog was on. She gasped when she saw Chao approaching it. "N-no..." The echidna said, seeing them continue to march towards the killer.

This wasn't a normal hedgehog; it had a set of dragon-like wings sprouting out of it's back, along with two white horns behind its ears. It kneeled down to look at the creatures in front of it in silence, ignoring the bodies laying around.

The Master Emerald glowed, a blue substance escaping the jewel as it transformed and took shape. Chaos steadily formed out of the liquid, looking at the hedgehog. It dashed towards it at incredible speeds, and it dodged as Chaos stopped, the Chaos in its arms as it turned around, glaring at the creature.

"Stop!" Tikal weakly shouted, running towards both of them.

Chaos looked towards Tikal, looking at the wounds she had received from the bloody fight beforehand. Its hands glowed an ominous green, healing them.

"I thought I killed all of you..." The hedgehog growled, looking at her. It was a male, if the appearance didn't give it away already...

Tikal trembled as she stared at the monster. "W-why did you do this?!" She said in anger. "Why did you kill so many people?!" The echidna shouted.

"One of you is going to kill me. I'm simply preventing that from happening..." The creature snarled, claws unsheathing from his hands. "Die."

Chaos suddenly hit the hedgehog, a yelp escaping him as he fell to the ground. The deity stood in front of Tikal, the sky a dark orange as fire raged along the island, burning vegetation and destroying the remains of the village nearby.

It set the Chao in a pool of water, it's gaze still fixed on the monster before them.

He rose to his feet, snarling as he drew a massive black sword. It glowed brightly, dark energies surrounding it as it transformed into a dark red blade.

"...Who are you?" Tikal said, backing away as Chaos kept it's glare, getting into a fighting position as it surrounded itself in Chaos Energy.

A grin formed on the hedgehog's muzzle. "I am Raxaga, and you aren't going to live to see what I am going to do to this world. Humans took everything that mattered to me, and now... I'll finally get my revenge."

Chaos leaped towards Raxaga, punching the hedgehog in the face before grabbing him, throwing the monster into the ground. He recovered, quickly swiping its brain. Chaos screeched, disintegrating into a puddle and retreating back to the Master Emerald. A beam of energy shot into Tikal as she backed away from the hedgehog.

Raxaga walked towards her with a twisted grin. "Finally... Stay still and I'll make this as painless as possible." He growled, lifting up his sword.

The echidna was about to give up and let herself die, but just as the demon was about to end her life she held out a hand. A spear of light energy lodged itself into Raxaga's chest, and an ear-piercing roar made itself known as he was knocked into a flaming tree. It fell onto him, both engulfed in flames. He leaped out, burned and slowly regenerating as he turned around and retreated, flying off.

End Flashback

Knuckles opened his eyes, groaning. He sat up tiredly, looking around. He saw Shadow beside him, unconscious. "...What the hell...?" He said aloud, confused. They were in a room, yet Sonic and Tikal were nowhere to be seen.

He saw a familiar emblem on the wall.

"Shit!" He shouted in realization as he saw Shadow slowly wake up. "Where are we?"

"We're in Eggman's base!" He said, getting the Ultimate Lifeform's attention.

"Why the hell would he want us? We aren't restrained." Shadow replied, slightly confused.

"I don't know..."

The door to the room opened, and the person who came in was none other than Eggman himself.

Knuckles glared at him. "What do you want?!"

"You should be thanking me," Eggman said rather annoyed, looking at the two. "If I didn't come in any sooner both of you would be dead."

Knuckles looked at him skeptically, but recalled the events before he was knocked out. It did make sense...

"Why did you save us?" Shadow said to the doctor, still suspicious.

"I need your help."

"Why would we want to help you after you murdered Tails?" Shadow said venomously, glaring at him. "If I wasn't helping him I would let Sonic kill you."

Eggman swallowed thickly; he didn't have a lot of room. "It was an... accident. I didn't mean to kill him." The doctor replied. "I meant to kill Sonic. It's not my fault the brat-"

Shadow ran over to him in an instant, holding him by his neck.

"Listen, Doctor. You might think this is a fucking game, but I am just as willing to kill you as Faker. I can relate to him, so explain yourself without tarnishing a dead person's name."

He reluctantly let go, jumping back as he kept his glare on the doctor. Knuckles was quiet, contemplating silently about the flashback...

"I... I didn't mean to kill Tails. He was the one who jumped in the way." Eggman said, rubbing his neck.

"So, you want us to protect you yet you're the one who damn near started all of this?" Shadow asked.

"Y...yes... If you can keep me safe than maybe I can come up with something to turn... Sonic back to normal." Eggman stammered.

Knuckles suddenly came back to attention. "Guys..."

Shadow looked towards the echidna. "What?"

He didn't want to talk about the occurrence... not until he learned more. But Knuckles had to at least say something.

"I think Sonic has always been this way."

Shadow actually showed interest. "What do you mean?"

"I mean..." Knuckles paused. "...I had a flashback when I came into contact with Sonic."

"What was it?!" Shadow demanded, growing more impatient.

"It was Angel Island... There was this demon. It was... killing off my kind." Knuckles clenched his fists after saying that, looking down at the floor. He refused to believe it. He couldn't have... it wasn't possible...

"What did this "demon" look like?" Shadow asked silently.

"..."

"It looked like Sonic."
