''Shadow the Hedgehog'' Shadow is just like Sonic,he's as fast as Sonic, and cool like Sonic.Shadow was created by Preffesor Gerald Robotnik,who is the grandfather of Dr. Eggman.Eggman and Robotnik look a lot like twins. They have the same orange mustache,and they wear the same color of uniforms. Robotnik created Shadow to be the ultimate life form, and rule all kinds of life forms. Shadow's my favorite character.
