A young hedgehog who also happens to be Sonic's most loyal fan. Madly in love with the blue hedgehog, Amy is often seen trying to track him down, and thus finds herself mixed up in the conflicts between Eggman as well. Hardly a damsel in distress, Amy is one of the most powerful characters with her Piko Piko Hammer, though she often finds herself using it simply for comic relief. Of course, if Sonic is threatened, Amy will quickly step in to save him.
