Zarbon's True Power (ザーボンの秘めた力 Zābon no Himeta Chikara, lit. "Zarbon's Hidden Power") is the two hundred sixty-third chapter of the Dragon Ball manga.
Vegeta thinks Zarbon’s threat is hilarious, and Zarbon decides to explain his true power before Vegeta dies. Zarbon says that it’s a difficult transformation to bring out his true power. He prefers this beautiful form, which is why he can’t stand transforming. “But, I’ll choose transforming over death…” Vegeta laughs at the idea of him transforming like the Saiyans do. Zarbon says he has no need to transform into something large like those Saiyan monkeys do--it’s just his power that grows. Vegeta wants to see this. And then bam, Zarbon suddenly bulks up into an ugly, toad-faced gator-monster and rushes at Vegeta, grabbing his head, and gives Vegeta a nasty headbutt. He tosses Vegeta into the air, but Vegeta catches himself and dives back down towards Zarbon.
Zarbon flies up towards him, and they meet up, Zarbon’s fist to Vegeta’s face. Zarbon then kicks Vegeta off into the distance, and Vegeta just barely catches himself, running out of breath now. Zarbon tells Vegeta he can’t hide his surprise that he’s of a transforming race. Zarbon says things have now turned, and decides to tell him something good before he dies. “Freeza is also of a transforming race!” Vegeta freaks out and Zarbon says someone who can’t even beat him is certainly no match for Freeza, as he fires a huge ki blast at Vegeta. Vegeta just barely dodges it, but Zarbon grabs hold of him from behind. Zarbon then zooms straight down, and sends Vegeta crashing headfirst into the ground. Zarbon doubts Vegeta had survived that; and even if he did, he’d probably drown. He changes back to his normal form again and decides to report back to FrIeza about this. After Zarbon flies off, Vegeta slowly resurfaces and tries to pull himself back on land, vowing to get even stronger...
