How Cute.Cell's basic design was thought up by Dr. Gero as the ultimate artificial human while Gero was in a good mood due to successfully completing Android 19. Cell's original, larval form floats in Dr. Gero's secret basement laboratory. In the present timeline, the Present Cell is killed by Future Trunks and Krillin when they discover the basement (which included some blueprints). In Future Trunks' timeline, Future Cell is alive, searching for the Androids, when Future Trunks returns from the present timeline, but gets killed by Future Trunks' Heat Dome Attack. In another alternate timeline, Cell grows to full-size, cracks out of the machine, turns from a larva into its imperfect form, kills Future Trunks in order to steal his Time Machine, reverts to his larval form, and travels back to the present timeline in order to absorb Android 17 and Android 18.
