LOL, I remember this one. I made it as kind of a joke thread after seeing an old anime movie called Memories. One of the shorts in it called Stink Bomb was really over the top with the male lead's stench as the guy was completely clueless that he was killing everyone near him. He swallowed a pill that was actually part of a new nuke being made and it made him into a walking bio-weapon that could kill anything within five miles of him.
All I know is that taijutsu users are screwed here. :P
