I think Sableye is suppose to kinda like a goblin/troll.
Meh, it needs an evo.
I can understand goblin, but I've always seen it as more Impish or like a Brownie. From my understanding Troll's gotta be fairly big. (Then again, most of my troll "information" comes from a folk metal band's lyrics and image [Finntroll]).
"Oh hey, I'm one of the most popular Pokemon in DP, and at first glance, I'm not that great. But I'm actually one of the most broken Pokemon in OU, and now I've split the entire competitive battling community in two as to whether I should be Uber or not!"
This guy was just made to troll competitive battlers. I wouldn't be surprised if Sakurai himself had a hand in creating him.
