Cell
Cell is Dr. Gero's finest creation and the deadliest android of them all. Cell's biology contains DNA from many of the universe's mightiest fighters, including Goku, Vegeta, and Piccolo. As a result of Cell's composite DNA, his fighting skills surpass those of Earth's greatest warriors, and he is able to use their signature attacks as well. In other words, Cell is virtually invincible. In addition, Cell can use his tail to absorb the energy and powers of his opponents. When Cell first appears, he is in his most imperfect form, and his body resembles that of a giant lizard. However, after absorbing a few victims, Cell transforms into Cell Stage Two, and finally, into Perfect Cell. But don't let Perfect Cell's handsome face fool you. Every stage of Cell's metamorphosis is more dangerous than the last. When Cell finally achieves his perfect form, he challenges the warriors of the Earth to a great battle tournament he calls The Cell Game.
