Rotor is a mobian walrus and was a key member of the Knothole Freedom Fighters, using his skills and knowledge of technology and mechanics to provide the Mobians with an edge against the former despot Dr. Ivo Robotnik and, since his demise, the forces of Dr. Eggman. Following Sonic the Hedgehog's return from outer space, Rotor limited his involvement with field operations and stuck to providing data and technological assistance.
