Bulma is the most important supporting protagonist in the entire series. She is Goku’s oldest friend and she frequently aids the Z fighters in a non-combative capacity. Her knack for getting kidnapped is a consistent plot point. She is arguably the smartest person in the DBZ universe, inventing both the Dragon Radar and the time machine that brings her son, Trunks, back to fix the past. She is the only female character who exists on her own merits outside of a relationship to a man.
