Android #17 (人造人間17号 ,Jinzōningen Jū Nana Gō, Artificial Human #17) is a human forcefully turned into a cyborg by Gero along with his sister, #18. The two are released by Gero as a last resort, but they turn on their creator and quickly kill him instead. They begin to travel in order to find and kill Goku, coming into contact with the Z Fighters several times. In Future Trunks' timeline, he is a mass murderer who is later killed by Trunks. #17 returns one last time in Dragon Ball GT, when he fuses with a new #17 created by Doctors Gero and Myu in order to become the Super Android #17, who is finally defeated by Goku and #18.
