It was after-school hours on a Monday when it first happened. Sonic was racing through town, as usual, unaware of the fact that someone was waiting for him.

Shaun, a.k.a. Shadow, picked up his cell phone in answer to the ringing tones. From the rooftop of the corporate building, his eyes never left his target below.

"Yo. 'Fast and Furious' at your disposal," Shadow answered.

"I need you to rub someone out for me." a metallic voice on the other end replied. "The dame has already been delivered, so expect her when you return to your apartment."

"So, what'd I gotta do?" Shadow asked.

"You should see a blue-haired teenager running through town. Catch him and destroy him!" was the reply.

"Done," Shadow hissed, leaping from the building. He wasn't scared about landing; He did this all the time.

He landed right in front of the speeding teenager he was supposed to eliminate, and delivered a stable kick to the youth's head.

Sonic flew backwards due to the sudden change in kinetic energy direction. His head started throbbing heavily, as well as his sight was temporarily gone. What hit him?

"Too easy." a voice slyly smirked as Sonic tried to remember which way was up. Something tugged at him. Something about the voice.

Sonic finally found his sight just as a hand roughly grabbed the back of his shirt, jerking him to his feet. "I thought this would be harder." a voice whispered, with a sly smile more evident in his voice than his face. Sonic started seeing blurred shapes, including the shape of a young man, roughly his age, with really black hair and reddish-brown eyes. "I actually thought you'd be a challenge!" the voice mocked.

"Then think again!"

Sonic collided with the ground once again as something slammed into his attacker. He tried getting to his feet, but instead only got as far as lifting his body barely an inch from the ground. He was so tired, and his head hurt so much!

A few winks of sleep wouldn't hurt.

Knuckles punched the attacker across the face, leaving behind four bleeding gashes on the young man's cheek. However, now that the attacker had plenty of time to prepare for Knuckles' next punch, he also attacked. Tails watched in awe as the black-haired man pulled off ten, maybe fifteen punches on Knuckles before he even had time to blink! Knuckles, however, was used to this; Tails couldn't remember how many times Sonic and Knuckles would spar with each other to similar results!

Even so, sirens were heard in the distance. The black-haired young man suddenly stopped, giving Knuckles one last time to connect.

Sonic woke up in his room at the Anderson household. Looking around the best he could without moving, he noticed Tails, Knuckles (who had an ice pack on his face), Cody, Carl, and Mrs. Anderson were all there, waiting for him to revive.

"What happened?" he whispered, barely able to speak.

"As far as I can tell," Tails started to explain, "There's some sort of dark look-a-like of you here on Earth, as I have learned this planet is called. I don't know why he attacked, but he definitely did, but I was nearby enough to call Knuckles and the police, so you're safe now. That guy was as fast as you, Sonic!"

"Nah," Sonic laughed to himself, "He was a smidge too slow. By the way, Knux, what's with the ice pack?"

Cody answered before Knuckles could even open his mouth; "He got a black eye!"

Both Sonic and Knuckles lived by a hit code. One hit during a spar equaled one point. Usually, Sonic was several up on Knuckles, but the rare occasion would allow Knuckles to somehow have a higher score than Sonic at the end of the round. The black eye meant there was another party in the mix, and Sonic and Knuckles were allies by default.

This guy was going down.
