Kragoom

Traguam was one of the Great Old Ones. He destroyed planets by having sex with them. All the inhabitants on the planet he was mating with became mind controlled and offered no resistance. As a Clockwork, Iris Wildthyme was immune to the effect.

Wayne Bland II, who had switched himself into Panda's body, sacrificed himself by switching minds with Traguam. Iris went back to Trull and switched Panda's and Traguam's mind. Traguam, now in Wayne's body, was kept in the planet's insane asylum. (AUDIO: The Iris Wildthyme Appreciation Society)
