Sonic the Hedgehog (character)
Personality: Shadow is of Sonic's most pronounced rivals, but at the same time, is one of his friends. Originally an enemy, he is more like an antihero nowadays. Shadow's personality is very different from Sonic's, being very serious and somewhat cocky. He originally had an obsession for finding out the truth about his past, but now since he has found it, he is willing to live a normal life...as normal a life can be for Shadow, that is.He can also turn Super using the Emerald.
