Prologue: Possessed

Sonic lay on the ground in the dirty cage that Eggman had created. He would've left, but the cage was suspended over water, only being held up by a metal chain. How did he get here? Eggman had miraculously defeated him. With who's help, you ask? No one, he defeated him with just a trick. A trick that involved fake capturing Amy; when he got out of this cage he was going to have to teach Eggman a serious lesson.

The thing was…how was he going to get out of there? The water was below him and he couldn't jump 80 feet in head. This seemed like the best trap Eggman had made since…Well, since never! Good thing that Eggman forgot his cell phone (the phone that Amy had made him get when they started dating).

"Sonic, you there," Tails sounded concerned, but Sonic wasn't worried; besides, he was able to get out of something like that no problem; or so he thought…

"Yeah; though I'm a little banged up. Listen, it was a trap. Amy was never captured. I wouldn't be surprised if she's at her house right now cleaning or baking. I want you and Knuckles to get out of here as fast as you can." Sonic said, not wanting his friends caught in a similar trap.

"But, Sonic," Tails started to protest, but Sonic cut across him.

"Tails, I'll be fine. Trust me; I'll get out of here somehow." Sonic reassured him, smiling even though Tails couldn't see it.

"Okay, but be careful. I don't think we can handle a depressed Amy if you get yourself seriously hurt." Tails warned, hanging up.

"Don't worry, bud, I'll be fine." Sonic promised, positioning himself so his back is against the back cage wall. Truthfully, he didn't know what was going to happen. Will he be okay? Well, Sonic didn't care. He had full confidence that he was going to be fine. But only if he knew what were coming next.

Eggman walked into the area, a platform unfolding in front of him with each step he took. "Ah, Sonic, finally I get the pleasure of capturing you."

"What do you want now, Eggman?" Sonic asked snidely, grinning. "You need me to destroy some of your robots?"

"No, but I do need you to do something for me." Eggman answered, walking around Sonic's cage. "I need you to break open this box for me. None of my robots can do it and I have full confidence that you can."

"Sure Eggman." Sonic agreed, taking the metal box. "Though, I bet you have to open it to activate the trap, right?"

Eggman smiled widely, saying, "Nope, holding it will do just fine." And with that, he pulled out a joystick-button. With an evil smile, he pushed it.

Sonic dropped the box as a very dark blue, nearly black, aura came out of it. He backed up as it came straight for him. He jumped, but it caught his leg. The aura started encasing him from the leg up. Sonic could feel the slightly-familiar power flow through his limbs, entering his main body. It took him a few minutes but he remembered why this felt familiar; this was the power of Dark Sonic; the power of rage, fake chaos emeralds and pure negative energy. He yelled out, trying to resist the power, but he couldn't. In mere minutes, it had devoured him completely.

Dark Sonic turned his head towards Eggman, but he didn't destroy the cage. Everyone knows that Dark Sonic is of the good alignment, but takes pleasure of destroying things and hurting others. But this wasn't just merely Dark Sonic; this was an entity that Eggman had basically created. He was a servant of Eggman; he would serve no other, no matter whom he had to harm.

Eggman laughed, "Yes, it was a complete success! Sonic," Eggman stated calmly. "I want you to go back to your little "group". Tell them that you need some rest and need to eat. They'll take care of you. But you must be in your regular form again. No matter what happens, you don't attack them and bring them back here until I say. Got it?"

Dark Sonic nodded. "Yes, finally I'll be able to get rid of the other-" Eggman stopped in midsentence, looking at Dark Sonic. Dark Sonic fell to his knees then collapsed onto the floor of the cage, becoming regular Sonic again. "Hmm…I guess he needs some more power to sustain him. No matter, I was planning to put Sonic in a pod anyways, so I can give him a fake memory." And with that, he walked out of the room, having two guard robots destroying the chain and then taking the cage with them as they followed their master.

Sonic woke up to find himself collapsed outside of Eggman's base. How did he get there again? Oh yeah, he had defeated every single robot that Eggman had created. He hadn't saved Amy, because she wasn't there to begin with, and had escaped the cage that Eggman had put him in.

Sonic frowned at the memory. That memory…It doesn't seem real. Sonic furrowed his brow, trying to figure out the mystery of why the memory didn't seem real. Tails was in it, so was Knuckles, just like before. All of Eggman's robots that he never had seen before until now were there as well. But it didn't seem right. It was strange.

Sonic shook off the feeling that the memory was a fake and stood up. He wobbled a bit, noticing the multiple cuts and bruises. But…How did he get those scratches and the bruises? He didn't remember feeling any pain while he was defeating the robots. Maybe that was because he was so busy concentrating on destroying them that he wouldn't feel any injury that might have been inflicted on him.

He shrugged and started walking; only to be stopped by Tails and Knuckles. "I'm sorry I didn't leave like you asked me but I got worried! You were taking so long to get out! It's been 4 hours since we last saw you enter the base!"

"4 hours," now the memory definitely seemed like a fake one! "Are you sure? I'm pretty sure that it was only an hour or so!"

Tails and Knuckles turned to stare at each other, confusion on their faces. "Sonic, what are you talking about?" Knuckles asked.

"Huh. I'm pretty sure it was an hour. Maybe I'm wrong." Sonic shrugged his shoulders and started walking away; not voicing his concerns about the possibility of fake memories being implanted in his head.

Before he could go much further, though, he collapsed onto his hands and knees. Using his right hand, he clutched his side as he felt a wave of dizziness and pain wash over him like a wave washing over the shore of a beach. Flashes of the first time he turned into Dark Sonic appeared before his eyes. He sucked in his breath; he tended to try not to think of that time in order to prevent any other Dark transformation incidents like that one.

Tails and Knuckles ran over to him. Sonic, by now, was on the ground, passed out from the great strain that had been put on his body for the past 4 hours. Tails and Knuckles lifted him up and put his right arm on Tails' shoulder and the left arm on Knuckles' shoulder. They didn't know what had happened to Sonic, but it didn't seem like anything good.
