Artificial Human #17, known as Android 17 in English adaptations, is a fictional character introduced in the Dragon Ball manga by Akira Toriyama. He also appears in Dragon Ball Z, Dragon Ball GT, and Dragon Ball Super.
Originally a human, he was transformed into a cyborg by Dr. Gero, just like his twin sister.
In Future Trunks' timeline, #17 is a mass murderer.
He is killed when Cell self-destructs but is later revived along with others who were killed by Cell. With the second wish, Kuririn removes the explosive device from #17. The last time we see him in Dragon Ball Z is in the woods, donating energy for Goku's Genki-Dama. His survival through the Kid Buu saga highlights his good nature, as Vegeta wished for only good people to be revived when the Earth was restored after being destroyed by Kid Buu.
In Dragon Ball Super, #17 returns as part of the Universe 7 team and ultimately sacrifices himself to hold back Jiren.
