81

Android 81 should have never existed in the first place. Doctor Gero's original intention was to construct Androids 21, 17, 18, and 16 after the Red Ribbon army collapsed. However, Towa and Mira, Time Travelling Demons, would not have it so. Towa used her power to compell Gero to construct another Android, 81. 81 had a short life outside her pod after being awoken by Gero. It wasn't long after 17 and 18 left the lab did 81 get taken to Conton by a Time Patroller to face the Supreme Kai of Time who, after much deliberation, decided to make 81 an honorary Time Patroller. Her mission was to fix the timeline she came from, causing her to do battle with 17 and 18, Cell, and even Mira himself. With the help of Trunks and the Supreme Kai of Time, she was able to fix the timeline before it got too out of hand. When she returned to Conton City, she elected to become a full fledged Time Patroller, helping save time from evil such as Towa and Mira. She is currently on an extended "vacation" to Earth due to...complications in Conton.
Android 81 is effectively an anti-hero. She does her jobs for the Supreme Kai of Time as they come but is rather brutal with her opponents, effectively beating them to a pulp and coming close to killing at points. She's sarcastic, a bit rude, and very blunt with both critisism and compliments (although complimetns from her are more or less non-existent). However, her personality is not without the major flaw of overconfidence. Although capable in fights, she still likes to take on more than she can and usually pays the price for it. But as she says "What doesn't kill you, you can always kill later".
