I'm pretty sure I used this guy in a Final Fantasy some time. Or maybe it was Lufia.
Point is, he looks a helluva lot like he belongs in a fantasy JRPG. and I mean, he is in a JRPG, but Pokemon isn't really fantasy. more technology than anything else.
anyways, he's got that nice blue/orange color scheme, but not much to identify him as a Fighting-type gym leader. Other than the fact he's the leader of a gym on an island to the southwest, which seems to be where Gamefreak puts all their Fighting dudes.
His pose and frame suggest he's athletic, and with that freaking name I'd obviously guess he's a fighter, but the design alone really doesn't communicate that at all. some knuckle wraps, or a martial arts belt, something like that would be good. I dunno, he just seems more attached to making sure everything in his life is blue and orange than looking like he trains beefy muscle Pokemon to punch things.
