I used Popeye for the longest time (while working on Sweethaven Village) and then I swtiched to Spelunky Guy. Right now, I'm using the Baron, but that's because I'm building a world for my kids and it seems appropriate to use royalty.
Templar, because I'm usually a warrior and it's the only decent armor that's not from another series (like Halo or Gears of War.) Also it looks great in chainmail (without the headpiece.)
I never even played the game before, I just like how the skin looks. :3
I play ALOT of gears of war
