Diarrhea. Specifically the diarrhea brought about from eating a meal containing large amounts of curry. Thus: The Curry Fury.
3 stages of The Curry Fury:
1) The Curry Worry - meal has been consumed, digestion is in process and you start to plan your escape.
2) The Cury Hurry - digestion is in its final stages, you stand, you run, you panic.
3) The Cury Flurry - at last! the evil, combustible waste is expelled at never-before-seen fiery velocity... hopefully into the intended, flushable container
The Fury wears a modified space suit. It is designed to resist extreme temperatures. His flamethrower, unlike other flamethrowers, uses rocket fuel. He has a rocket pack that allows him to fly.
The Fury is this ex-cosmonaut who is equipped with a flamethrower. His body was severely burned in space, possibly be reentry, and thus his body is incapable of having any senses.
