Stardust is a super wizard. He has vast powers. So why is he such a jerk?

Because the universe is infinitely bigger and vaster and more complex than he can imagine. Being a wizard is all about controlling reality. Being a super wizard is all about controlling super reality or something. Ordinary humans get through their day by no understanding how insignificant they are in relation to the rest of the universe. Stardust knows that for all his powers he is still but a blip in existence. His ego has a problem with that.
