Banna is the sister of Goku, Raditz, and Gamma. She is the only woman to become a Super Saiyan. She can transform into a Super Saiyan 4 and she can sense a person's power level without a scouter. She has a power level of 300,000 and her brother, Goku, is suprised with her power. Raditz thinks she is to spoiled because everyone in her family, exept Raditz, is a hero so what I'm trying to say is she is a hero. She cares deeply for her nephews and lives on Earth on a house not too far from Goku's. Goten loves his aunt so much and he never wants to leave when he goes to her house. She has a son named Kahan and he can go Super Saiyan
