Yeah, I suppose I could see POW being a not-horrible character, in a supernatural/horror context ... it's having him in the superhero genre that makes him seem just such a mis-fire, for me. I mean ... pretty sure part of his look there too is that he's wearing the dog-tags of all his fellow soldiers who died, around his neck. Not cool. It's not fricking jewelry; why are you wearing it??
But yeah, if he's in a darker, spookier context, it could work.
