Pyro

Pyro is one of the two protagonists of Gone With the Blastwave and a Flamer of the Red Army. He was a member of West's Squad from Issue #18 to #33 when his kill count gains him his own squad.

Personality
Pyro seems to be the comedic flair of the two protagonists, constantly suggesting terribly structured plans, which often end up failing.

Pyro also has a clear obsession with fire, in Issue #9 he is entranced by the sunset which looks to him like the "world burning". He has a similar moment in Issue #55 while watching an airstrike. He later dreams about demonic creatures burning the world, which he describes as "good" (Issue #58).

Pyro also seems to have suicidal tendencies, in Issue #5, Sniper sarcastically suggests a plan to kill the Yellows that would require his own sacrifice, Pyro states as an observation that the plan probably wouldn't work because it wouldn't kill all of them, showing that he wasn't worried with the fact that he would die. In Issue #23 Pyro says he was considering the "Blue's way out", as shown in Issue #14, the "Blue's way out" was suicide.

Skills
He has some leadership skills (in a minimal level). He also has a flame thrower, even though only ever see him use it as a light source. We know that he has one because of the canisters containing flammable gas on his back, in Issue #44 he searches a fallen Yellow flamer stating that he's "been dry for months" hinting that his own gas has run out, explaining why he has never used his flame thrower. This especially impressive given that he was without a rifle till Issue #21, this is less impressive given that he accidentally shoots a squad mate in the same issue.

Disclaimer: Contrary to popular belief, he isn't a demolition expert, in Issue #25, a Red soldier jumps out of a crowd and says: "I'm the only demolitions expert!", a lot of people thought this was Pyro because the symbols on their helmets are alike, but this isn't the case considering that this soldier doesn't have the "gas canisters" on his back that Pyro has. In Issue #28 this same soldier is seen with no gas canisters and the similar symbol, considering that it is closer and clearer you can see that the demolitions expert's symbol (a diamond shape with an explosion in the centre, representing demolition) is different from Pyro's symbol (a diamond shape with a triangle like shape in the centre, representing fire).

Behind the Scenes
It was recently confirmed by Morr (creator of the comic) that Pyro's real name is Ramirez (changed from Rodriguez). It was also confirmed that Pyro forgot his own name.
