Pyro is a mysterious, mumbling, masked pyromaniac wielding a flamethrower. However, despite being a mercenary and an having an affinity for fire, Pyro is actually unaware of the death and destruction they are spreading; the Pyro sees their own weapons as innocent items such as lollipops, bubble blowers and rainbow throwers when, in reality, they are axes, flare guns and flamethrowers. They believe that they are spreading color and happiness, but are actually causing mass destruction and murder.
