It was supposed to be just a simple sketch to figure out how to make these guys a tad more realistic. Or at least more detailed. It turned silly. He's mad due to the color of his clothes. Green is so not his color.
He probably gets to keep his service pistol. Pit gets to have decidedly unusual weaponry, after all.
Well not in the BIBLEverse. They don't want to contaminate other worlds with better technology so they have to stick with lower tech like swords and shields. They can use guns in parts of Hell and higher tech worlds, I believe. You'll have to ask Maia or Gitte about that one. I don't think it's in their wikia.
