@Kayriel He had a lot more personality going for him, he's a dick sure, but he'd actually help too. And not always for material gains, he'd also work for favors. And if the interests aligned he'd work for free(since it would help him too). He also worked for his powers, his levels, his ability to use 3 and special words came from training and constant experimentation. He saved 2 of the 4 heroes from being used in a plot, has managed to use his own name to stop a war. Anyway, his personality doesn't turn him into an an unreasonable and self-serving brat as one would expect, which is why he is a "cheeky" bastard, not an "insolent" one.
A much more human personality than what he has here.
