Shadow was struck with amnesia, and attempted to destroy the Earth, believing it was Maria's request. However, after recovering much of his memory, Shadow ended up assisting Sonic in saving the Earth from the Biolizard. Shadow's somewhat rough past has made him very bitter and cold in current years, and due to this, he is capable of joining the cause of good or evil. He always ends up doing what is right in the end, however, and has grown a friendly rivalry with Sonic and Silver.
