Too Much Power? (あぶない３倍界王拳！ Abunai San-Bai Kaiōken!, lit. "The Dangerous 3-Fold World King Fist!") is the two hundred thirtieth chapter of the Dragon Ball manga. The chapter's anime counterpart is the conclusion of the episode "Goku vs. Vegeta" and the beginning of the episode "Saiyan Sized Secret".
Goku thinks about the risks of Kaiō-Ken x3 on his body, and Vegeta yells at him to come on. As Vegeta goes on about how he is number one among the Saiyans, Goku thinks that he’d just lose anyway if he doesn’t use it. Yajirobe thinks he should run away, but then Vegeta perks up, noticing Kakarrot is now powering up. “Body, hold together!! Kaiō-Ken times three!!!!!” Far away on his little planet, Kaiō begins worrying about him using more than x2, and can’t believe the situation. All of the “civilians” are at Kame House now, and Bulma is checking on the battle with Raditz’s scouter. It’s going off like crazy; 17,000… 19,000… 21,000… And then it blows up! Now Goku is the one doing all the crazy weather stuff, and Vegeta freaks out. Goku flies over toward Vegeta and punches him in the face, sending him flying. Then Goku zooms down below the falling Vegeta, and flies straight up to attack him, but Vegeta catches himself and prepares for the attack.
Goku makes a sharp turn right in front of Vegeta, and so Vegeta frantically tries to turn and throw a blast at him. But Goku zooms out of the way and then kicks Vegeta straight through a rock formation. Vegeta busts out of the rubble, screaming like a madman, and then Goku flies at him. Vegeta frantically tries to punch him, but Goku easily avoids it by jumping over him. Then Goku flies back at Vegeta from behind, and knees him in the back, sending Vegeta into the air. But Vegeta comes down and charges at Goku, but Goku ducks it and punches him hard in the gut. Vegeta bends over, coughing up blood, and Goku powers down from Kaiō-Ken. Vegeta can’t believe Kakarrot’s surpassed his battle power, and Goku thinks Vegeta’s a really tough guy. Yajirobe thinks Goku might just win this.
