Dr Gero's perfect fighting weapon. Though increadibly weak in his first form, and not much better in his second, Cell's final form is one to be reckoned with. He is very powerful, and posesses all the techniques learned by the z warriors. He came to the present in Trunks's time machine a year before Trunks showed up, and hatched while the z warriors were fighting the androids. He was another ego guy, and because of it, died when he pushes Gohan's power to a level beyond any others. Gohan killed Cell with a giant kamehameha.
Cell Jrs: Not a whole lot on these guys. They were spawned when Cell wanted to push Gohan to his hidden power. They pounded mercilessly on the z fighters, but were easily destroyed by Gohan after he tunred Super Saiyan 2.
