Piccolo is a fictional character in the Japanese Dragon Ball media franchise created by Akira Toriyama. He made his appearance in chapter #161 "Son Goku Wins!!", published in Weekly Shōnen Jump magazine on February 9, 1988, as the reincarnation of the evil King Piccolo, who was positioned as a demonic antagonist of the series. However, it is later revealed that he is in fact a member of an extraterrestrial humanoid species called Namekians from an exoplanet called Namek, those able to create the series' eponymous wish-granting Dragon Balls. After losing to Son Goku in the World Martial Arts Tournament, Piccolo teams up with him and his friends in order to defeat newer, more dangerous and powerful threats, such as Vegeta, Frieza, Cell, Majin Buu, Beerus, Zamasu, Jiren, Broly, and Moro. He also trains Goku's eldest son, Gohan, and the two form a very strong bond.

Dragon Ball is a Japanese media franchise created by Akira Toriyama in 1984. The initial manga, written and illustrated by Toriyama, was serialized in Weekly Shōnen Jump from 1984 to 1995, with the 519 individual chapters collected in 42 tankōbon volumes by its publisher Shueisha. Dragon Ball was originally inspired by the classical 16th-century Chinese novel Journey to the West, combined with elements of Hong Kong martial arts films. Dragon Ball characters also use a variety of East Asian martial arts styles, including karate and Wing Chun. The series follows the adventures of protagonist Son Goku from his childhood through adulthood as he trains in martial arts. He spends his childhood far from civilization until he meets a teen girl named Bulma, who encourages him to join her quest in exploring the world in search of the seven orbs known as the Dragon Balls, which summon a wish-granting dragon when gathered. Along his journey, Goku makes several other friends, becomes a family man, discovers his alien heritage, and battles a wide variety of villains, many of whom also seek the Dragon Balls.
