You're Sonic!!
You don't remember anything that happened these years, it's like several moments of your life have been erased from your mind. Even though you felt that hole, that feeling that something was missing, there was someone with you, supporting you: The doctor Ivo Robotnik. Well, he liked to call himself Eggman. He was who guided you and told you about what you were and who you were—needless to say, he lied to you. The truth was that Eggman had brainwashed you, he was now taking advantage of you, and because of your situation you believed anything he said; after all, you don't remember anything—. You had been working with him thanks to the gratitude you had for him, helping him with his goals and other things. But, there always were a pair of 'heroes' trying to stop you. They treat you as if they knew you, even if you didn't. But for u, everything they said was wrong. So you keep fighting those idiots, not knowing why they're standing in your and Eggman's way exactly.
Tonight, you were looking for a chaos emerald that Eggman asked you to get. You found it on the beach, buried in sand. However, when you were going to take it, someone ambushed you and snatched it from you. You could recognize him as soon as you saw his orange-reddish flash moving with him. Shadow. Eggman told you about him, that you had to be very careful, especially with him. You followed that hedgehog, fighting him, but you couldn't beat him. That started to stress you out.
You fought for hours, trying to snatch the emerald from each other. You ended up fighting on the roof of a building. You didn't see a kick coming that Shadow would give you right in the head, leaving you almost knocked out. You fell to the ground.
"Sonic... What the hell did he do to you?..."
Shadow whispered, staring down at you with... sadness. The ebony one walked and stopped in front of you.
"My... love."
You heard him say very low, with some impotence. Shadow clenched his fist, while you felt more than confused and disoriented.
