"You can't hurt me. I made you."
— Future Dr. Gero to Future Android 17 and Future Android 18 in "Mystery Revealed"

Future Dr. Gero (らいのドクター・ゲロ Mirai no Dokutā Gero), also known as Future Android 20 (らいじんぞうにんげん20ごう Mirai no Jinzōningen Nijū-Gō), is the alternate timeline counterpart of Dr. Gero.


Same as his present timeline counterpart.


Same as his present timeline counterpart, although he apparently was more ruthless due to programming Future Androids 17 and 18 to hate humans, making him directly responsible for their path of destruction in the Future timeline. It's possible that this action was due to him learning of Future Goku's death, thus making his original goal of creating the Androids for the purpose of killing Future Goku pointless and redundant.



Human Gero Past

Dr. Gero as a human after Goku defeated the Red Ribbon Army

According to Future Trunks in the manga, Future Dr. Gero created Future Android 19 along with Future Android 20 but was killed by the two of them. Future Trunks fought them but fighting alone was defeated.[1]

Six months after the death of Future Goku, Future Dr. Gero released Future Androids 17 and 18 to kill Goku as part of his plot for revenge, but he was killed by the two of them.

Dragon Ball Super[]

"Future" Trunks Saga[]

His soul was erased when Future Zeno erased the future timeline to kill Infinite Zamasu once and for all. His soul still exists in the second alternate future timeline created by Whis in the anime, while in the manga it is created by Future Trunks and Future Mai traveling back to prevent Future Shin's death (and ultimately Future Beerus' death) with the blessing of Present Beerus.


Future Trunks states that he is unable to stand up to the combined might of Future Android 20 and Future Android 19.[1]
