Kaitudan was a mutated dinosaur who menaced Japan.
Challenge of the GoBots cartoon
Kaitudan began life as cloned Pteranodon created from bones by Doctor Hyashi at UNECOM's Japanese base. However, it was mutated by her vengeful colleague Doctor Eiji Tsuburaya, becoming the violent Kaitudan and breaking out of the base. While Ichigar tussled with the Guardians Kaitudan made off for the mountains and menaced a scout troop before Leader-1 and Turbo arrived. Kaitudan attacked and chased the Guardians, only to be caught by Cy-Kill's Astrobeam. He was later used by the Renegades to attack Tokyo and caused considerable damage until Tsuburaya was able to gas it into unconsciousness. The beast was then returned to his Pteranodon form.
