Who is your favorite DBZ character?

Mine will probably be Bulma because she is one of the characters that lasted in all of the Dragon Ball series, from Dragon Ball to GT. She actually has to do with most of the entire series anyway like Goku. Without her bumping into Goku in the very beginning which began the whole mission of finding the Dragon and creating inventions or things to help him live later in the series; especially the Cell Saga (like the time Goku was told that he will die from some sort illness in the near future, however, the future Bulma made a medicine that will help him survive and told her son Trunks to give it to Goku in the past), we would not have our favorite DBZ Warrior Goku. Bulma is also my favorite because she marry a tough guy like Vegeta that could kick *** and also that she still look youthful when she is older after having like two kids.
