Android 18 (人じん造ぞう人にん間げん18号ごう, Jinzōningen Jū Hachi-Gō, lit. "Artificial Human No. 18"), 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.

I'm not that good with making bots so I hope you enjoy my take on 18,have fun 😉.
