Risking his own life, Goku charges up to a triple-Kaio-Ken. The sheer power generated overloads Bulma's Scouter and draws a warning from Kaio-sama. With newfound strength, Goku ferociously attacks Vegeta! Unable to counter the onslaught, Vegeta is quickly overwhelmed.

     At the Kame House, Uranai 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 the Turtle Hermit fears that Goku is pushing himself beyond his limits.

     Vegeta continues to take punishment from Goku, and grows furious that his own royal blood has been drawn by a lower class fighter. Goku's body begins to have trouble enduring the strain imposed by the triple-Kaio-Ken, and he realizes he has to settle things quickly. Seething with anger, Vegeta decides to destroy Goku, along with the rest of the planet, by unleashing his Gyalick Ho energy attack! Goku counters with a triple-Kaio-Ken-powered Kamehame Ha, and when he decides it isn't enough, raises himself to a quadruple-Kaio-Ken!

     Vegeta is blown away by the power of Goku's blast. Yajirobe, who had been watching the proceedings in hiding, comes forward to congratulate Goku. However, a simple pat on the back turns out to be more than an over-exerted Goku can handle, and he buckles in pain. Upon hearing from Goku that the Saiyan survived the attack, Yajirobe again retreats into hiding.

     Freeing himself from the crest of the Kamehame Ha, an outraged Vegeta decides to transform himself. After failing to find the moon, he returns to the scene of battle with another means to realize his transformation! Vegeta lectures Goku on the physics of Brutz waves, reflected from the moon, and how they cause a reaction in the tails of Saiyans. When their radiation reaches a level of 170 million zeno, it allows them to transform. It all seems to go over Goku's head, until Vegeta creates a small, artificial moon with his own energy. Without a tail, Goku is unaffected, but as Vegeta stares at it, he completes a terrible transformation into a giant weremonkey!
