Android 13
Android 13 (人造人間13号 Jinzōningen Jū San-Gō, lit. "Artificial Human No. 13") is Dr. Gero's thirteenth Android creation. He is designed to continue Gero's vendetta against Goku, who overthrew the Red Ribbon Army as a child.
While the main timeline version of him was destroyed by Gero, this parallel world Android 13 makes his debut as the main antagonist in the film Dragon Ball Z: Super Android 13!.
