Sistine is half Saiyan, half Gelboian. She was born at planet Gelbo and was raised by her mother along with her grandparents. Around the age of 16 her mother finally revealed to her why she didn't have a father. A few years ago, a team of Saiyans had attacked the village killing hundreds. Her mother was raped but she was also from the few that survived. At one point she realised she was pregnant and she decided to keep the baby. That baby was Sistine. After Sistine learned the truth, she set a path of training to find and fight the Saiyans. She quickly grew more and more stronger, she had Saiyan blood running through her veins after all. She left her planet at the age of 17 and with a spaceship set course to find Planet Vegeta, where the Saiyans lived. After a half year journey going from planet to planet, she run into a time patroller going by the name Knishi. He was on a mission to correct a time distortion and after certain events happened, she helped him. After listening to her story, he informed her that planet Vegeta was destroyed long ago. Sistine lost her purpose and had nothing to do from now on. After getting the permission of the Supreme Kai of Time, Knishi took Sistine with him back to Conton city. There she became a proud time patroller who would protect time from any evil doers. After she witnessed the events of history with her own eyes, she started having more respect for the Saiyans. She wasn't proud for her father but for the Saiyans that were alive at that point of time. Goku, Vegeta, Gohan and the rest where really admirable people in her eyes. So her hatred of the Saiyans vanished over time and she burried her desire for revenge. With a lot of training she unlocked the powers of many Super Saiyan forms and continues to grow even stronger by time.
