He thinks of himself as the strongest in the entire universe or at least his ego thinks that.He was beaten by goku ,well supposedly him but it seem to me he was beaten by his son.Then again thats my opinion and he is the prince of vegeta who marries bulma.He then has a son (later a daughter)named trunks who he cares for ,but doesnt show it until he is about to sacrafice himself to kill buu.What can I really say he has a lot of pride.He is capable of becoming ss and ss4 he skip 2 and 3 (cheater) and his technigues are Galaxy Cannon,Final Flash,and Big Bang Attack.
