A creation of Dr. Gero's, he was assembled using the DNA from the best fighters in the universe. The project was taking too long, and he abandoned the project. However, Dr. Gero's computer remained working, even after his death. Cell was completed a few years after Mirai Trunks had destroyed #17 and #18 in his time, which Cell needed to absorb to become "perfect." Seeing there was no solution to this problem in his time, Cell murdered Trunks and traveled back to when the androids still existed. Cell eventually finds what he's looking for, and goes perfect. He holds a game where he challenges anyone in the world to fight him, or else the Earth would be destroyed. Cell is killed by Gohan with a one-handed Kame Hame Ha.

andriod 16 is supposed to be the weakest of the andriods when really he is the strongest of them all his mission is to destroy goku but before for he can he runs into cell telling andriod 17 he is the strongest and that 17 would be much less than a match makes andriod 17 mad.16# never reaches goku becuase dies trying to kill perfect cell that is pretty much everything about cell
andriod 17 was one of may fav fighters.the reason he died or sacraficed was so that cell would become perfect cell.he could of avoided this mess if he did not have such a big ego thing going on if he would of fought smart he might of won but instead his anger took over and cell absorbs him also he should of learned when he was about to get absorbed and piccolo saved him to bad.
Created for one sole purpose, #17's mission is to destroy Goku. Constructed from a human base, #17 is not completely mechanical. Initially under the control of Dr. Gero, he breaks free and kills him. Even with his creator destroyed, #17's internal programming still gives him the urge to search for Goku and destroy him. This objective is soon put behind him when he is forced to run for his life from Cell. An adept fighter, #17 makes a reappearance in GT as a villain.
Back when Goku had obliterated the Red Ribbon Army, a solitary scientist named Dr. Gero worked hard to create warriors capable of defeating this powerful boy. He toils for decades, but his work finally comes to fruition three years after the defeat of Furiza. Fearing death, he has his mind implanted in one of his androids shells, and becomes #20. Dr. Gero is responsible for the creation of Cell and all the other androids bearing the Red Ribbon logo, and like his servant #19, he can absorb energy from attacks and physical contact.
