Androids 17

Android 17 is one of the bosses in Dragon Ball Z: Kakarot.

Cell Saga
Android 17 is the result of cybernetic modification of the human boy Lapis. He was an orphan and, along with his twin sister (who would later become Android 18), would make a game of stealing from and extorting others for money, though they never harmed the innocent. Because the pair were outlaws with no friends or family, Dr. Gero felt they were the perfect subjects for his modifications.

Android 17 has the appearance of a teenage boy with long black hair. He is very powerful and possesses a limitless supply of energy, but his rebellious nature forced Dr. Gero to shut him down. Android 17 is playful and somewhat childish, viewing the mission to kill Goku as a game best enjoyed at a leisurely pace. After being revived by the Dragon Balls following the Cell Games, Android 17 traveled the world. On his travels, he fought a group of poachers on an island of monsters and afterward befriended the ranger there. He eventually married her after becoming a ranger himself.
