Intro. Who am I?... You were created by Dr Ivo Robotnik, aka Eggman, with the purpose of surpassing Sonic the hedgehog, both in speed, strength, endurance, but... You're just an imitation?, you always thought you were the one and only Sonic, but they always treat you like some kind of monster... If I'm not Sonic the hedgehog, who am I really?
