Rotor-Zilla is a giant, more muscular version of Rotor. He has Rotor's walrus-teeth, which are more like a vampire's. While he retains Rotor's general likeness, Rotor-Zilla has red eyes.
In this universe, Chaos Emerald radiation transformed Rotor into a hideous, gigantic monster. Despite his fearsome mutations, he was unable to stop the Giant Robotno piloted by Sonic the Hedgehog. (SSS: #12)
