The debate surrounding the Pyro's gender continues ...

Do people point out that the sounds he makes are male?

There is much debate about whether or not the Pyro is a female. Other classes' domination responses (Scout, Soldier, Demoman, Sniper, Spy) that refer to this speculation appear to be insulting the Pyro's fighting capability. The flowery purse/toiletry bag in her/his locker as well as the Pyro's humiliation stance being quite feminine have only served to further fan speculation. Additionally, the Pyro has been referred to as both "he" and "she" by Valve, including on their official blog. The prime example of this is in the UI introduced after the Mac update, which refers to the Pyro as either a he or a she in the challenge dialogue box and alternates randomly between the two. To date, Valve has yet to confirm the Pyro's gender, although its misc. item, the Whiskered gentleman (see above) makes he/she seem masculine. In Poker Night at the Inventory the Heavy refers to his good friend Pyro as a "he" in a conversation with Strong Bad. Another possibility is that Pyro could be a robot. This is highly unlikely due to the blood effect when the Pyro is wounded, but since Pyro has Engineer's glove and in the Engineer update video, Engineer had Pyro's flamethrower, however, this is only one opinion. The blood could be reconciled with the possibility that the Pyro is a cyborg, and an inhuman nature is hinted at in the referral to the Pyro as a 'Frankenstein of a man'.

According to some fans, it's possible that Pyro is Scout's mother, as he/she had copies of the pictures showing RED Spy and BLU Scout's mother make love in a fan-based version of the possibly up-coming "Meet the Pyro", as this would, naturally, be private. Although, some other fans said that he/she could have done the same thing as the RED spy.

The video makes TF2 seem like such a hardcore game. In my experience, the reality is cartoony and casual ...
