Yeah, I don't know what it is, but it looks out of place. Maybe because KOTOR hasn't really gotten any world-building, so the Republic Trooper is kind of a fish-out-of-water with no one to interact with. He feels like he'd be more at home in the HALO line than Star Wars. Or like when I was a kid and a random GI-Joe figure would make an appearance in my Star Wars scene. Or like a speed metal song in a classic rock playlist...yeah, there are guitars and drums in both, but they don't really fit together.
I've never bought him, but also I never wanted him. Overally he feels like a foreign knock-off of Commander Cody (you nailed it, Nicklab), but one that looks far more derpy than Cody. Like he hastily spraypainted his older bother's motocross gear to cosplay as Commander Cody. And his minigun looks so underdetailed that it could have come from a McDonald's toy.
Eh, if he wins I guess that's cool for those that wanted him, but I still don't think I'd buy him. He just doesn't really fit with my collection.
