Tails of Future Not-Quite-Past (孫悟空の過去！！ Son Gokū no Kako!!, lit. "Son Goku's Past!!") is the one hundred ninety-seventh chapter of the Dragon Ball manga. The chapter's anime counterpart is the second half of the episode "Reunions".
The alien is surprised to learn that "Kakarot" doesn't recognize him, and asks if he forgot his mission. Goku doesn't understand, and denies being Kakarot. The alien asks if Goku ever suffered a blow to the head that may have resulted in memory loss. Goku hazily recalls and confirms the event. Master Roshi tells of a conversation he had with Son Gohan, where the latter mentioned taking in a violent and aggressive child, who, after falling down a ravine, became good-natured, and calm. Goku realizes the child was himself.
Realizing Goku has forgotten everything, the alien reveals that he is Goku's older brother, Raditz, that they were born on Planet Vegeta, and are both members of the warrior race, the Saiyans. Raditz further claims that Goku was sent here as a child to wipe out all life on the planet with the help of the moon, so that the Saiyans could resell it to a new species. Master Roshi, Bulma, and Krillin all realize what he means, but Goku doesn't know of his Great Ape transformation.
Raditz becomes angry after noticing Goku's missing tail, and accuses him of trying to blend in with the humans he was supposed to kill. Confused, Goku denies his Saiyan heritage, and tells Raditz to leave. Raditz explains that there are only four Saiyans left alive after a meteor collided with their home planet, and asks Goku to join them to assist in conquering a difficult planet. Goku refuses. Raditz notices Gohan's tail, and realizes he's Goku's son. Raditz forcefully abducts Gohan, and demands 100 corpses be lined up on the beach of Kame House by the next day, or else he will kill Goku's son.
