Shadow the Hedgehog

Shadow is an artificially processed transgenic hedgehog, created with Black Arms DNA by Professor Gerald Robotnik. He is known as the ultimate life form, also sharing Sonic's agility and speed. He has a strong sense of purpose and pursues his goals by any means necessary. Shadow prefers to work alone and distances himself from essentially everyone, with few exceptions. He has a very strong sense of protecting mankind due to his relationship with Maria Robotnik in the past. After recovering from amnesia, he has had a better understanding of living faithfully.
