He is the prince of all the sayins.  He is one of the strongest of all sayins.  His rival is Goku who he has been trying to kill for as long as he could.  He also can fuse with Goku and they become Vegeto, and fused together like that they were poweerful enough to beat majin buu.  His Father was obviouly the King of all Sayins.  He has a son that is named trunks that is very powerful in his own way.   He blew himself up to try to kill majin buu and was nearly sucsseful.  As evil as he sounds he is good at heart sometimes.  He sacrifices himself to try to save the world. He says he doesn't care about the world but he does.  He was turned evil under the power of bobedy (The evil green midget with a weird voice.)  He tried to fight it as much as he could but could hold back.
