3 months after sonic hero's ended metal sonic's attack on the world eggman again went into hiding from sonic and his friends. sonic is well relaxed he hasn't done much work in weeks eggman hasn't even shown up yet with some new robot and Amy's gone with cream and cheese to the beach for the week so not much is going on. little did he know someone is watching him from the shadows waiting for its chance to tear him apart. Sonic noticed something move in a near bye bush so he went to see what it was. sonic reached into the bush and he pulled out a small cat with a weird scar on its eye sonic looked closer at the scar he could make out what looked like a claw mark.
