Shadow The Hedgehog is an black hedgehog with red stripes and the Chaos powers, he's known as the world's "Ultimate Life-Form". He likes nothing (it says that in the bio of Shadow in SaSASR). Shadow is an rival of Sonic the Hedgehog, they both start a rival race, and fight. He is created by the Dr. Eggman's grandfather, Gerald Robotnik. Shadow have been angry because the G.U.N Soldiers shot Maria Robotnik by the accident, he must get revenge, but can't.
His first appearance is in Sonic Adventure 2. His age is unknown and it's because he's "created" by the proffesor.
Shadow stole the chaos emeralds and teleports away so people may not see him stealing a chaos emerald. The police or G.U.N Soldiers, have arrested Sonic because they through he did that, but Sonic says it's not him. People are in fact confused who's that hedgehog that stole Chaos Emeralds.
