Artificially created 50 years ago aboard the space colony known as the ARK to be the "Ultimate Life Form", Shadow the Hedgehog is a strong, sophisticated and noble fighter that vows to give the people of earth a better chance at life. On the surface, he might seem like a stone cold and bruting agent of G.U.N. that only serves to be Sonic's bitter rival and to fight powerful opponents, but truly has a heart of both gold and sorrow due to his former life on the ARK being taken away from him by G.U.N. long ago with his final memories from that place being of his best friend, Maria Robotnik being shot after asking him to bring hope to humanity. He now serves to protect the lives of humans, ignoring his past and not letting anyone dictate his actions as many have tried to do numerous times. Use this as a reference for how the voice should sound.
