Android 18 (人造人間１８号 Jinzōningen Jū Hachi-Gō), originally named
Lazuli (ラズリ Razuri)[4] when she was an ordinary
human, is the older twin sister of
Android 17 and
Dr. Gero's eighteenth
android creation, designed to serve Gero's vendetta against
Goku. While her interests do not initially deviate from this expectation, her curiosity to activate
Android 16, in spite of Gero's orders not to do so, leads Android 17 to take it upon himself to rebel and murder Gero. Eventually, Android 18 becomes a member of the
Z Fighters, as well as the wife of
Krillin and the mother of their daughter
Marron.
