Android 17 (人造人間１７号, Jinzōningen Jū Nana-Gō), Lapis (ラピス) when he was Human, is a character in the Dragon Ball manga, and the anime series Dragon Ball Z and Dragon Ball GT. He is Dr. Gero's seventeenth android creation, designed to serve Gero's vendetta against Goku who overthrew the Red Ribbon Army as a child. Despite his interests not initially deviating from this expectation, Android 17 takes it upon himself to kill Dr. Gero, who is uncooperative with Android 18's curiosity in activating Android 16.
