"A Hot, Unbounded Battle! Gokū versus Vegeta" (限界を超えた熱い戦い！悟空対ベジータ, Genkai o Koeta Atsui Tatakai! Gokū Tai Bejīta; FUNimation "Goku vs. Vegeta") is the thirtieth episode of the Dragon Ball Z anime.
Gokū instructs Kuririn and Gohan to leave the battlefield, because he doesn't want them to get hurt. With no one in their way, Gokū and Vegeta begin their fight for the fate of the Earth. Even with Gokū using his Kaiōken technique, Vegeta is still more powerful. Gokū has no choice but to try a Kaiōken x2, but even with this increase in power, he still can't overpower Vegeta. His only choice is to try a Kaiōken x3, but the incredible surge in power could destroy his body.
