Iogon is a kaiju that appears in the 1992 PC game Ultra Strategy, Mobilization of the Science Patrol!
Subtitle: Bio Monster
Iogon was a biotechnological weapon created by the Kemur Man after learning from the mistakes of their brother in Ultra Q. It can fly, release erasing energy rays that transport living organisms to a different dimension and shoot dissolving liquid from holes on it's body. However, Iogon is physically linked to the Kemur Man controlling it. Should that Kemur Man die, Iogon will die too. The existence of this does bring up some continuity issues though especially in 'The Forbidden Words' episode of Ultraman.
