Iogon is a kaiju that appears in the 1992 PC game Ultra Special Tactics Squad Go! Subtitle: Bio Monster
Iogon was a biotechnological weapon created by the Kemur people 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 controlling it. Should that Kemur die, Iogon will die too. The existence of this does bring up some continuity issues though especially in 'The Forbidden Words' episode of Ultraman.
