Shadow the Hedgehog

Shadow the Hedgehog is also known as the Ultimate Life Form.

His theme

He looks like Sonic the Hedgehog and is as fast as him and he was his enemy for a time. Sometimes the two fight but they are not hated enemies. They're more like Goku and Vegeta fighting to prove who is ultimate.

When Shadow has a Chaos Emerald he is able to a power known "Chaos Control" which can teleport himself, others, or even attacks to anyway he chooses.

He was once a member of the Anime Empire and he fought in the Toon/Anime war. Now he fights to destroy Galvatron.
