Rip in the Universe (次元に亀裂!!ブウがキレちゃった!?, Jigen ni Kiretsu!! Bū ga Kirechatta!?) is the seventeenth episode of the Fusion Saga and the two hundred seventieth overall episode in the original dubbed and the uncut Dragon Ball Z series. The episode first aired on July 12, 1995. Its original American air date was November 11, 2002.
The episode starts off with Super Buu fighting Super Vegito. Super Buu fires a Super Kamehameha, but Super Vegito deflects it back at his face. Super Buu is greatly outclassed by Super Vegito and tries his Dangerous Liquid Bomb technique, but to no avail. Super Vegito then mocks him. Angry at not being able to keep up with Super Vegito, Super Buu gets really angry and tries to break through the dimensional walls.
Dende says that this could cause the universe to collapse, and has a flashback of when Super Buu ripped a hole through the Hyperbolic Time Chamber. Vegito tries to attack but Super Buu places an energy barrier around himself. When Vegito starts to get pushed back, he begins to Power Up and proceeds to break through the shield before uppercutting Buu into the ocean below, stopping the attack. After Super Buu resurfaces, Vegito taunts the humiliated yet quiet Super Buu.
"It's not much fun being hunted down, is it Majin Buu? Being hunted just the way you hunted down our friends. DOES IT HURT?!?!"
- While Super Buu digs deep into his well of power, Dende tells Mr. Satan that this is what Buu did in the Hyperbolic Time Chamber. He knew this because he saw Buu escaping the Hyperbolic Time Chamber at Kami's Lookout.
- Yamcha wears his Turtle School uniform again in this episode.
- While fighting Olibu and Gorilla, in one scene the Turtle School badge is not on Yamcha's clothes but in the very next scene, the Turtle School badge appears.
- During the fight with Olibu and Gorilla, Yamcha is seen without a halo.
- This is the first time that Super Buu refers to himself as "Super Buu".
- This is the first time that Super Buu fires steam from his head when he is angry.
- Due to transnational differences, when Vegito was under water, in the original, he stated he didn't feel a thing from those blasts. In the dub, he stated Buu's aim was lousy since he can't sense Vegito's location.
