I fear no man. But that thing, it scares me.
--The Heavy commenting about the Pyro
A Team Fortress 2 character.
A reverse firefighter, he wears a flame-retardant suit and a gas mask that muffles his speech. Rumors suggest that "he" may actually be a she, or a robot.
Some fan theories believe The Pyro to be a male, while some others believe him to be female. His nationality is still to be debated until now.
