Dragon Ball Z: Supersonic Warriors/Cell

Cell is the final creation of Dr. Gero, said to be the perfect artificial life form. He was given this name since he was created from the cells of the most skilled fighters on the planet - this includes the likes of Goku, Piccolo, Frieza, Krillin, Vegeta, and the list goes on. His story arc is the Cell Games Saga, in which Cell, bored with the little competition given to him by the Z Fighters, decides to threaten the planet with his idea of a tournament.
