"Fire a Ki Wave powerful enough to warp time and space from your mouth and blow your enemy away."
Both Super Buu and Gotenks use this technique to create a dimensional portal and escape from inside the Hyperbolic Time Chamber after Piccolo blew up the entrance. Super Buu (w/ Gohan absorbed) later uses the Vice Shout as a last resort against Super Saiyan Vegito. Super Buu claims it possesses enough power to destroy the whole universe and uses the Voice Shout to create an energy shield to protect himself, but Super Vegito powers up and, with some effort, punches through the shield, preventing the attack.
- Weak Vice Shout - A far weaker emulation of the vice shout utilized by Super Saiyan Gotenks and Piccolo in a failed attempt to collapse the dimensional walls.
Video Game Appearances
Super Buu uses it in a cutscene in Dragon Ball Z: Buu's Fury. The technique was named Vice Shout in the Budokai Tenkaichi series, where it is one of the Blast 1 techniques used by Super Buu and Super Saiyan 3 Gotenks to momentarily paralyze their opponent. In Dragon Ball: Raging Blast 2, Super Buu uses it as his signature skill.
In the story of Dragon Ball Z: Shin Budokai, Gohan compares Janemba's ability to create portals in time and space to Super Buu and Gotenks' Vice Shout technique.
In Dragon Ball: Xenoverse, it is called Dimension Cannon and is Super Buu's Evasive Skill, though it lacks the ability to create portals and functions more like a weaker version of a Mouth Energy Wave. This skill can also be obtained by the Future Warrior as a reward in Parallel Quest 41: "Frieza's Nightmare Returns!".
- Kami uses a similar attack in the Garlic Jr. Saga to break down a thick wall of what appeared to be glass.
- A similar technique is utilized by Kid Buu shortly after his formation, causing the skies to instantly grow dark, shake the planet, and shatter various light fixtures, with the environment turning back to normal only after ceasing screaming so he can blow up Earth with a Vanishing Beam. This technique was later named Angry Shout in Dragon Ball: Xenoverse.
