The Saiyans(サイヤ人Saiyajin) are the primary fictional humanoid extraterrestrial race in the Dragon Ball manga by Akira Toriyama. The Saiyans are a naturally aggressive warrior race who are, purportedly, the strongest warriors in the fictional Dragon Ball universe. Protagonist Son Goku (originally named Kakarot) is revealed to be a Saiyan upon the race's introduction. Most of the Saiyans were exterminated by galactic overlord Frieza after Goku was born. With only a few known survivors, they are functionally extinct.
