#18 is the twin sister of #17. She is quite pretty and loves fashion. She has exactly the same destruction capabilities as her brother, and is just as cruel and deadly. Her objectives are exactly the same as #17, to wipe out the entire human race and conquer the planet. However, #18 life is completely changed when Cell arrives. Cell, dominating the Z fighters in everyway imaginable, is also looking for #18. Luckily, Krillin risks his life and saves #18 from Cell. Eventually, Krillin falls in love with #18 and Krillin doesn't want her to suffer anymore. As a result, Krillin uses the power of the Shenlong to remove the self-destruction bomb inside #18, hence transforming #18 more of a human being than a robot. #18 is deeply touched by Krillin's gesture and the power of love and her own humanity has made her to erase her evil personality, and becomes a part of the Z team. Krillin and #18 are later married, and they have a daughter called Marron.
