Cell (Dragon Ball character)
Cell is an artificial life form (referred to as a "Bio-Android") created by Doctor Gero's supercomputer from the cell sample of the universe's strongest warriors, possessing the genetic information of Goku, Vegeta, Piccolo, Frieza, King Cold and Tien Shinhan in an underground complex beneath Gero's secret laboratory. Cell is designed to evolve into the "perfect" being by absorbing two Androids, #17 and #18. The Cell that appears as the primary antagonist of his titular arc is from the future, awakening after his development is complete to find that the Androids have been destroyed by Trunks. After he kills Trunks, Cell uses his time machine while regressing into an egg to travel back four years, to before the androids appeared, arriving in the present timeline. After hatching and metamorphosing from his larval, cicada-like form into his insect-like Imperfect form, Cell kills off thousands of people and absorbs them to increase his power in preparation to absorb the Androids. After he has managed to absorb the energy of entire cities of people, Cell finds Android #17 during his fight with Piccolo. Cell then breaks Piccolo's neck before Android #16 holds the mechanized villain off. However, he is able to find an opening to absorb #17 and evolves into Semi-Perfect Cell. Cell quickly dispatches #16, but he is unable to absorb #18 thanks to the intervention of Tenshinhan, who holds him back at the cost of his own life force before being rescued by Goku, along with a surviving Piccolo.
