Bio: Shadow is an android-like mobian hedgehog and is the end result of Project: Shadow becoming the ultimate lifeform. He was rivals with sonic and wanted to destroy the world for killing maria but sonic told him that maria wouldn't want him to do such a bad thing, so after rescuing sonic from eggman's evil scheme, he turns good.
Early Life: Shadow was created by gerald robotnik in the space colony ark 50 years ago. He was gifted with the powers of the alien black doom through his blood, giving him the DNA of a black arm. However, Black Doom wanted to use shadow to destroy the planet mobius, but gerald wanted to make shadow the greatest protector of the planet and so black doom left. After shadow's creation, he met maria who shadow liked and they became friends. Later, GUN soldiers raided the ark seeking to find the ultimate lifeform and destroy its knowledge. While trying to attempt to escape the ark, maria was shot and killed by a GUN soldier, which shadow just saw right before his pod was sent to earth where he'll be asleep for 50 years.
Present Life: 50 years later, shadow was awakened from his stasis when eggman stumbled upon him. Shadow thanks him and wants to help him in his world conquest because of maria's death, so he worked with his creator's grandson by collecting the chaos emeralds. Later, he fights sonic in the space colony ark and loses. Then, he sees sonic and knuckles getting into trouble with the biolizard, so shadow intervenes and beats the biolizard. But, the biolizard used chaos control to teleport himself merging itself with the eclipse cannon. With the power of the chaos emeralds, sonic and shadow transformed into their super forms and battle the finalhazard. Shadow then sacrificed himself to save everyone and the world by sending the beast and the ark into orbit, he was exhausted that he fall into space. It was believed that he died, but he was actually rescued the bem and healed him back to health and returned to earth and joined sonic's group.
Future Life: Shadow will become king of mobius after dr.eggman gets killed by chaos knuckles and sonic disappears. He'll marrie sally acorn and will rule for 19 years until sonic will show up and overthrow shadow so sonic can be king.
