Wait, but aren't the Gaesatae modeled on Psycho? That'd seem a good indicator.
Malrubius' thing says he's from Alabama, and we Southern boys are often good in a scrap (or so that persistent Civil War myth goes).
Now, if you went by the little pictures by people's names (are those avatars? whatever), then its a tossup between Khelvan and Urnamma, I suppose.

Brackets are a good idea though. You could put 'em out in March, let people fill 'em out, and then...well, it fizzles out from there, I guess.
