"The Strongest Warrior in All of History is Gokū's Brother!" (史上最強の戦士は悟空の兄だった！, Shijō Saikyō no Senshi wa Gokū no Ani Datta!; FUNimation "Reunions") is the second episode of the Dragon Ball Z anime.
Gokū and Gohan arrive at Muten Rōshi's island to meet Bulma, Kuririn, Muten Rōshi, and Umigame. Quickly the others notice the difference between Gohan's behavior and that of Gokū as a child. Gokū informs his friends that Chi Chi refuses to allow Gohan to fight, instead he studies constantly. The same mysterious alien arrives at the island and reveals himself: he is a Saiyan warrior named Raditz, and he is Gokū's older brother. He also reveals that Gokū's real Saiyan name is Kakarotto. Gokū learns that he was sent to destroy all life on Earth, but his memory loss from a terrible fall as a child prevented this outcome. Raditz came to Earth to get Gokū to join him and the other two remaining Saiyans, and he won't accept a refusal.
- In the FUNImation dub of the anime series, a plot hole is introduced when Raditz claims that the planet Vegeta was destroyed by a meteor "three years" prior to the start of the Dragon Ball Z anime series, as opposed to being destroyed far earlier in the timeline. This is not present in the original Japanese version.
