Sonic was strapped to the table in Robotnik's lab, still and quiet.
His eyes were a dull red, and the only emotion he could feel was rage.
Tubes were connected to his body, transferring an unknown substance into his veins.
He lay there, mind full of dark thoughts. He hated the world, a planet full of greed and selfishness. He hated his family, kind souls uncorrupted by the state of the Earth.
As he lay stewing in his innermost, darkest thoughts, Doctor Robotnik walked into the room, followed closely by his assistant, Agent Stone.
"Ah, you're awake!" The scientist said with a smile. "Excellent! We will start immediately, then."
Robotnik walked over to Sonic and turned off the machines and pulled out the wires from the hedgehog's body.
"Tell me," Robotnik said, sitting down in a nearby chair. "What do you feel now?"
"Rage," Sonic snarled, eyes glowing a deep red now. "Hate."
Robotnik nodded. "Very good. Towards whom are these feelings directed?"
"Everyone," Sonic answered, fingers twitching with the lust to be free and unrestricted. He wanted to let his anger out, he didn't care how it was done.
"And, what do you plan to do about it?" Robotnik asked gleefully, already anticipating the answer.
"Kill them all," Sonic hissed, now visibly struggling against his binds.
"Alright, he's ready," Robotnik turned to his assistant. "Stone, release him. He's one of us now."
Stone shifted uncomfortably. "Uh, sir, don't you think we should do a few more tests before we let him out? He could turn on us."
"While that possibly is indeed quite high, I have faith that this experiment will turn in our favor," Robotnik said calmly. "But I don't pay you to think, I pay you to do. Now let him go."
Agent Stone sighed, but did not try to argue with his superior. He hesitantly walked over to the table and pressed a green button on one of the machines, and a loud beeping sound was heard. The binds holding Sonic to the table retracted, and the blue hedgehog immediately jumped onto the floor.
"Isn't he marvelous, Stone?" Robotnik said with awe in his voice as he gazed at the now brainwashed Sonic. "This could be my greatest work yet! Turning Earth's hero to our side will guarantee us a solid victory! Our enemies will surely be destroyed with Sonic the Hedgehog under our control!"
Stone was still, not saying a word as Sonic turned towards him, staring with those creepy red eyes.
Robotnik was busy giving Sonic a new mission. "Now, Sonic, I want you to do something for me. This is very important, understand?"
Sonic stared at Robotnik, expression hateful and angry. Crackling sounds were heard as the hedgehog charged his powers.
"I want you to kill your family," Robotnik continued. "They were holding you back, and preventing you from reaching your real potential. With them gone, you'll be unstoppable!"
Sonic snarled softly, eyes turning a faint shade of blue now as electricity crackled around him.
"Uh, sir, I don't like what he's doing," Stone said hesitantly, backing up a few steps. "Maybe we should-"
Before Stone could finish his sentence, a bright burst of electricity erupted from Sonic and slammed into Stone, sending the scientist flying back and hitting the wall with a loud crash.
Robotnik stared at Sonic with a shocked expression, then slowly started to grin. "YES, this is perfect! Stone, you're fired! Sonic is my new sidekick now!"
The blue hedgehog was just a blur as he ran over to Agent Stone and hauled him to his feet.
Stone was dragged over to Robotnik's workbench, whimpering in fear as his head was slammed into the table and held there with a strength that the assistant didn't know was possible in a hedgehog.
Sonic reached over and grabbed hold of an electric buzzsaw, flicking the switch to turn it on.
Realizing what was about to happen, Robotnik decided to intervene. "That's enough, Sonic, let Agent Stone go now! It's not quite time for our plan to start yet!"
Sonic ignored him, bringing the blade of the buzzsaw towards Stone's throat.
"Sonic, that's enough, release Stone now, please." Robotnik spoke a little louder to be heard over the sound of the whirring buzzsaw.
Stone turned his head to glance up at Sonic, his body seeping fear. He saw the hedgehog, eyes glowing a mix of red with hints of blue, concentrating on his current task as the weapon was brought steadily closer towards Stone's throat.
"Sonic!" Robotnik put a hand on Sonic's shoulder. "Listen to me! We need to-"
Sonic turned and raised his hand, shooting a burst of electricity at Robotnik. Like Stone, Robotnik flew backwards, hitting the floor with a pained thump.
Sonic returned his attention to Stone, turning the buzzsaw back on and holding his head in place.
"Look at me," Sonic said softly, and Stone whined in fear, not wanting to go out like this, "I like to see the light go out."
The blades were now so close, and Sonic kept Stone's gaze directed at him as he started cutting into his neck.
Stone screamed, the pain unbearable, and Sonic laughed with glee as blood sprayed out in spurts.
Stone's head fell off the table, eyes still open, and Sonic turned off the buzzsaw and bent down to pick up the head, walking over to Robotnik and dropping it next to him.
"You're welcome, Master," Sonic said mockingly.
"Why did you do that?!" Robotnik said fearfully, staring with shock at his former assistant's severed head. "That's not what I wanted you to do!"
Sonic kicked the head around like a soccer ball while he thought. "Well, you said that you didn't need him anymore, so I think I've done you a favor. And, I didn't like the way he looked at me, anyway."
"You-" Robotnik was at a loss for words, shocked at how merciless and vile this new Sonic was. "Maybe this was a mistake."
"No, that's not necessarily true," Sonic said, playing with the blood leaking from Stone's severed head, drawing symbols on the floor, "You made me better, and I am grateful for that. In fact, I feel like you deserve a reward."
Before Robotnik could speak, Sonic ran over to the wall and grabbed a sword, running it through the scientist's body.
Robotnik stood there, shocked as he saw the blood erupt from his torso, then he fell to the floor as a pool of blood began to surround him.
Sonic knelt down and watched with sadistic glee as Robotnik slowly died, the light in his eyes slowly dimming.
Once he had fully died, Sonic stood up and walked out of the lab, dragging his blood-stained fingers across the wall, leaving behind a scene of carnage and chaos.
