The True Colors of the Masked Man (仮面男の正体は!?, Kamen Otoko no Shotai ha!? lit "The Masked Man's True Identity?!") is the ninth episode of the Fortuneteller Baba Saga and the seventy-sixth episode in the Dragon Ball series. The episode first aired on August 26, 1987.
Grandpa Gohan repeatedly slams Goku against the floor, as his friends watch on painfully, wondering why his own Grandfather would put him through so much pain. Bulma demands that Master Roshi help his student, but the latter refuses, saying that Goku's grandfather has a purpose behind his actions and was never a reckless man. Meanwhile, Emperor Pilaf is trying out his new power suit, while Shu and Mai spy from a satellite on Goku, learning from the battle with his Grandpa, that his tail is his weakness, something they plan to exploit. It turns out, Pilaf has the final Dragon Ball and has jammed the Dragon Radar using a Dragon Radar-proof box.
Eventually, Goku's tail rips off. Gohan surrenders and reveals his face to Goku, who runs towards him, embracing him and breaking down in tears, as his friends look on happily. Bulma retells her adventures with Goku. Gohan chooses to stay dead and vanishes after a farewell. Fortuneteller Baba reveals the exact location of the last Dragon Ball, as promised. It is being transported in a red car.
- Goku's tail is cut off for the second time. It is later grown back in "Goku vs. Sky Dragon".
- Not counting when Goku was just a baby, this is the only time in the entire anime or manga where Goku, either as a kid or an adult, broke down in tears.
