Cyborg Rotor

Cyborg Rotor is an alternate version of Rotor Walrus. In his zone, Robo-Robotnik attempted to defeat the Freedom Fighters by turning them into cyborgs. However, the enhanced abilities granted to them by the transformation allowed them to march on Robotropolis for a final confrontation with him. Sadly, Robo-Robotnik turned the tables by completely roboticizing himself and Cyborg Rotor, along with his teammates (apart from Cyborg Sonic), were killed or neutralized by the menace. (StH: #19)
