Android 18

From the dragonball universe, Android 18 is a human remodeled as an android by Dr. Gero. She becomes a good guy after Gohan defeats Cell. Android 17's twin sister, one of the androids created for making Cell perfect. She is slightly less powerful than 17. She becomes Krillin's wife, and has a kid with him named Marin, much to Goku's surprise. She uses computer speak every now and again, demonstrated in her amazement to how Vegeta became so much stronger in such a short time, after training in the Hyperbolic Time Chamber, saying "It just doesn't compute 16, there's just no way".

The hottest and most kickass woman in Dragon Ball Z. Bulma has her beauty and brains, but Android 18 is a total badass. Beats up SUPER SAIYANS, has unbelievable durability, infinite stamina, and even managed to get Krillin to settle down and have a child with him (and somehow he survived this). She’s like a Terminator… except better. A total milf cyborg how could easily kill you… but that makes her hotter.
