Android 18

Android 18 (人造人間１８号, Jinzōningen Jū Hachi-Gō), Lazuli (ラズリ, Razuri) when she was an ordinary human, is the 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, 18's curiosity to activate Android 16, in spite of Gero's orders not to do so, leads Android 17 to take it upon himself to murder Gero. Eventually, Android 18 became an ally of the Z Fighters, as well as the wife of Krillin and the mother of their daughter Marron.

She has been voiced by Meredith McCoy and Colleen Clinkenbeard.

P Team/B Team storyline
Getting bored, she decided to travel the Multi-Universe and then she found out that Dr. Gero and some of his androids are still around, so she's decided to find them and destroy them. Along the way, she finds Scorpion and his allies under attack, so 18 saves them and then joins them.

She later helped the P Team in the fight with Galactus, during which she finally killed Dr Gero.

The Multi-Universal War of Destiny
18 joins her team, M.O.D.A.B, the B Team, and the P team in this adventure to fight Discord. She also helps her friends against the Maverick Sigma.

She first shows up during Sektor's attack on the Scorpion Squad which was stopped by Crypto. She does what she can to help the squad and her friends. She and the squad later meet Jack Noir and he and 18 fought. She beat Jack Noir easy but he hit with Roboenza, making her go beserk. 18 nearly kills her friends but Hiscord, Cassandra, and Lizbeth's efforts remedy that.
