Sonic roared and slammed into Metal, sending it flying into the ground. Sparks started to fly, and the robot exploded, sending debris everywhere.

Tails watched in awe at the transformation. "W-what happened to you?!" Sonic looked into a puddle on the ground. He saw his reflection and was shocked. "W-what?!"

Knuckles stared at Sonic in shock. "H-how did you total it in ONE blow?!" Sonic shrugged and replied, "I don't know. It just happened. I think it was because I got angry when you guys were beat up.

Tails nodded in agreement and said, "Well, that's enough fighting for today. Let's head home. Sonic transformed back into his mutated form and smirked. "I bet I can beat you both." Knuckles rolled his eyes and said, "Oh really, I can wipe that smirk off your face! Tails sighed as the duo sped off. He started his plane and flew off.

Shadow sat on a log in the forest. "That monster may have tricked those two fools, but I'm not fooled at all! Dr. Eggman flew by in his egg mobile. Shadow stared at him with hate.

The evil doctor stopped and looked at Shadow. "Well, well, if it isn't the black rodent!" Shadow rolled his eyes. "You sent that imposter out to kill Tails and Knuckles!" Dr. Eggman scratched his head. "Hmm? Do you mean my experiment that escaped 3 days ago? The ugly black one with wings?" The doctor said, fibbing slightly. Shadow looked suprised, then nodded. "I didn't mean to release that one. It was too evil. It killed all of my guards." Shadow slightly gasped.

"I'll make a deal with you. Trap Son- I mean my experiment, and I'll kill it on the spot." Shadow thought of this for a moment, then reluctantly nodded. "Good. All I need is for you to lure it over to this part of the forest. You have two days before our little deal expires."

Shadow glared at the doctor, then chaos controlled. Dr. Eggman laughed evilly. "HO HO HO HO HO! He's just as stupid as Knuckles!

Shadow ran through the city, trying to track down Sonic. He then saw him in Tails workshop. He grinned and ran in.

As soon as Knuckles saw Shadow, he got into a fighting stance. Sonic growled and Tails glared. "What do you want?!" Knuckles said. "Oh, I just found a Chaos emerald!" Shadow said, fibbing. Tails asked, "Well, will you show us?" Shadow nodded and chaos controlled the gang. No one noticed the dark grin on Shadow's face.

When the gang got there, they were greeted by the Doctor himself. He smirked and said, "You've been tricked fools! I can't belive Shadow, out of all people, would belive me! HO HO HO HO HO!" He then pressed a button on his remote.

A ray came out of a strange gun. It shot Sonic, and he screamed in pain. He transformed to the form we saw earlier, and stared blankly. Then, he snarled and attacked the gang. Tails gasped, and Knuckles punched Sonic before he could hurt anyone. Dr. Eggman laughed and flew off.

"Looks like I have some fresh meat..." Sonic growled, and attacked.
