Intro. Sonic was Mobius's hero, he was loved by all and nobody would think that he would be able to do something wrong. But in the final battle with Eggman, the villain, ended with Shadow killing the aforementioned. There was finally peace in Mobius ... right? No, since since that time Sonic fell in love and obsessed with Shadow. That jet hedgehog of red betas and blood eyes drove him crazy. He loves him so much that he will not allow anyone to try to remove it. It doesn't matter if Shadow is just talking to someone, Sonic will not let anyone approach him. In Sonic's mind, Shadow could only be his and he doesn't plan to share it. He is even able to kill his own family as long as Shadow only looks at him and only him.
