Vegeta before firing the Earth Splitting Galick Gun

"Saiyan Sized Secret" (いまだくう!すべてをけた さいおうわざ Ima da Gokū! Subete o Kaketa Saigo no Ōwaza, lit. "Now, Goku! A Final Technique with Everything on the Line") is the 25th episode of the Vegeta Saga in the uncut Dragon Ball Z series. This episode first aired in Japan on December 20, 1989. Its original American airdate was August 4, 2005.



Goku after taking his gi off

Risking his life, Goku charges up the Kaio-ken to a triple. The incredible power generated overloads the scouter that Bulma took from Raditz's body and begins to worry King Kai. With newfound strength, Goku ferociously attacks Vegeta. Unable to counter the onslaught, Vegeta is quickly overwhelmed.

At Kame House, Fortuneteller Baba works hard to conjure up an image on her crystal ball. Although they have no way of telling how well the battle is going for Goku, everyone is excited that Goku's energy is so high, but Master Roshi fears that Goku is pushing himself beyond his limits.

Saiyan Sized Secret - Kyoufu

Vegeta is ferociously struck by Goku

Vegeta is viciously pummelled by Goku and grows furious that his own Saiyan blood has been drawn by a lower-class warrior, while Goku's body begins to have trouble enduring the strain imposed by the Kaioken x3, and he realizes he has to defeat Vegeta quickly. Fueled with anger, Vegeta decides to destroy Goku, along with the rest of the planet, by unleashing the Earth Splitting Galick Gun. Goku counters with a Kaio-ken x3 powered Kamehameha, and when he decides it is not enough, raises himself to a Kaio-ken x4. Unable to keep the Kamehameha back any longer, Vegeta is struck point-blank by the beam and rocketed into the sky, leaving Goku exhausted from the surge of energy.


Vegeta completes his transformation into a Great Ape

Yajirobe, who had been watching the entire battle in hiding, comes forward to congratulate Goku. A simple pat on the back turns out to be more than Goku can handle, and he screams in pain. Upon hearing from Goku that Vegeta is still alive and will return soon, Yajirobe again retreats into hiding.

Vegeta only barely manages to free himself from the Kamehameha, his battle armor now damaged. Now outraged Vegeta, decides to transform, but fails to find the moon and realizes that someone (Piccolo) must have destroyed it to stop him from transforming. Vegeta returns to Goku and reveals another way to transform via Blutz Waves, reflected from the moon, and how they cause a reaction in the Saiyans. When thrown into the sky, the Blutz Waves are activated, allowing Saiyans to transform. It all seems to confuse Goku, until Vegeta creates a small, artificial moon with his own energy. With his tail gone, Goku is unaffected, but as Vegeta stares at it, he transforms into a Great Ape.

Major Events[]

  • Goku increases his Kaio-ken to times three despite the risk it could cause on his body.
  • Vegeta attempts to destroy Earth with his Galick Gun technique but Goku is able to push it back using the Kaio-ken x4 Kamehameha.
  • Vegeta uses the Power Ball in order to transform him into a Great Ape.


  • Goku vs. Vegeta






Differences from the manga[]

  • Bulma using the Scouter at Kame House and the others voicing their concern on the battle between Goku and Vegeta is exclusive to the anime.
  • In the anime there is an additional scene where Goku using the Kaioken X3 continues to overwhelm Vegeta that was not present in the manga.


  • It is not clear what would have happened to Vegeta had he won the beam struggle against Goku. Vegeta said the planet would be destroyed, but as a Saiyan, he cannot breathe in space, and his Attack Ball was in a distant city.
  • Vegeta's trigger for his subsequent rage differs between languages. The Japanese version has him angry for Goku, "low-level trash", making him bleed his "noble blood" whereas the English dubs, even the uncut Funimation dub, has him angry in general at Goku surpassing him in brute strength without directly mentioning the bleeding. The former is rectified in the English dub of Dragon Ball Z Kai.
