Dr. J. Kintobor

Robotnik has another heroic self named Mayor Kintobor. In an experiment gone awry, he exposed an atoll to Chaos Emerald radiation, mistakedly believing the island to be uninhabited; the resultant effects mutated the Freedom Fighters of this universe into Godzilla-like monsters. The Mayor's appearance is the same as Eggman's, except the color of his outfit is reversed to be primarily white, with red stripes.
