Sonic the Hedgehog (character)
Shadow the Hedgehog: Shadow is a cloned hedgehog with super speed like Sonic's. He is actually immortal due to scientific experimentation, but he has the appearance of a 15 year old hedgehog. He is also known as Project Shadow and "The Ultimate Life Form". He is often mistaken for Sonic, although they have some differences between them. Shadow has red and black quills and they are more spiky then Sonic's (resembling Sonic's super form). Shadow was created by Dr Gerald Robotnik (Dr Eggman's grandfather), for the intent of creating peace on earth, on the Space Colony ARK. His creation, however, was enabled by the blood of Black Doom, the leader of an alien race called the Black Arms. His goals were different than Dr Gerald, as he wanted Shadow to collect the Chaos Emeralds for him so the Black Arms could rule Earth. After his creation, Shadow spent some time with Maria (Gerald's granddaughter and Shadow's first friend) who taught him about humanity, true friendship and how to be kind to others. But the G.U.N. (Guardian Units of Nations) thought he would be a threat to humanity. As a result, they eliminated everything related to the project, including the staff and Maria, who was in the process of saving Shadow. He was sent from the ARK in an escape capsule, but was captured by G.U.N. and was kept frozen (like Fry from Futurama) at their base at Prison Island. The death of Maria made Dr Gerald go mad, altering Shadow's memory while he was still frozen to manipulate him into trying to destroy Earth. With help from Sonic and his friends, he was able to regain his memory and his purpose to save the earth, and stopped Dr Gerald's plan to crash the ARK into the planet. This led to Shadow falling from space and getting amnesia, only remembering Maria's death. He went to find his memory, which lead to him defeating Black Doom and the Black Arms. He has made a commitment to live his life without the burden of his past. He took an offer from the present Commander of G.U.N. to work with them as an agent, but he still works on his own terms. Shadow has unique abilities to use the Chaos Emeralds in ways Sonic and friends have never shown to be able to. One of these is Chaos Control, the ability to warp and manipulate Time and Space with a Chaos Emerald's power. Shadow's first appearance was in 'Sonic Adventure 2'.
