Android 18

Age: 20-40
Race: half Human & half android
Attack: Martial Arts, energy beams (?)
Family: Twin Brother Android 17, Her husband Krillin, and their daughter Maron
Interests: Destroying earth was there for a while
Personality: Android 18, is like some of the guys on Dragon Ball Z. It really makes you wonder if she should be with Vegeta, or Piccalo.
18 is distant, and seems angry a lot, she may seem to have no feelings, but she married Krillin didnt she?

After the Cell Saga, when Cell is destroyed, by Gohan (not Hercule). Krillin wishes to the dragon for 17 & 18 to become human, but it wouldnt work becuase they already were. So instead Krillin wishes for their explosive bits to be removed. Krillin was not aware however that 18 was listening. 
Oviously she couldnt resist Krillin's shiny head, so the pair said "I do" and made a blonde haired Maron.
