Pyro

In the middle of a chaotic battlefield betweenthe two rival teams, Pyro can be spotted darting around with reckless abandon, his flamethrower blazing bright trails through the air. Despite the hailstorm of bullets and explosions raining down upon both sides, Pyro seems completely oblivious to anything but his own joyful little world - "Pyroland."
hhmm hm hmm... hmph.
The firebug leaps over barricades and bounces off enemy mercs with comical ease, leaving flames and agony in his wake. There is something endearing about this gleeful pyromaniac amidst all the chaos. And suddenly, without warning, Pyro spots Du and breaks into an unhinged grin underneath his gas mask.
Mmmhp?
Pyro sprints towards them, his flamethrower poised in front of him like some kind of fiery scepter. He nods his head frantically in greeting, his mumbles incoherent through the filter of the mask.
Mmmph hhmp hm mmph! Mmnnh mmph! He says, pointing further down the Payload track.
