Cell is one of the major super villains of the Dragon Ball manga and the Dragon Ball Z anime. He is the ultimate creation of Dr. Gero, designed to have all the abilities of the greatest fighters to have ever inhabited or visited Earth; the result is a "perfect warrior", possessing numerous favorable genetic traits and special abilities. Cell is the only Red Ribbon "Android" to not have the Red Ribbon insignia on him. He is also one of the few Red Ribbon Androids not directly completed by Dr. Gero; the others are Android 13, Android 14, Android 15, and possibly Android 8. Both Cell and Androids 13, 14 and 15's conceptions involved Dr. Gero's Super Computer.
