Break Cannon

Nappa powers up, opens his mouth wide, and gathers a dense sphere of ki between his jaws. Once the energy reaches critical mass, he releases it as a massive beam that tears through everything in its path. The technique requires minimal preparation compared to hand-based attacks, giving Nappa an element of surprise since most fighters expect energy blasts from the palms.

The sheer volume of energy Nappa channels through the attack makes it one of the most powerful single blasts seen during the Saiyan Saga, easily on par with or exceeding many hand-fired techniques of that era.

Nappa first uses a weaker version of the Break Cannon against Chiaotzu after the small fighter's Psychic Spark fails to do any damage. The blast sends Chiaotzu reeling and demonstrates just how outmatched Earth's defenders truly are against a Saiyan elite.

The full-power version comes out during Nappa's clash with Goku. After exchanging blows, Nappa unleashes the Break Cannon at the newly arrived Saiyan, who counters with a Kamehameha. The two beams collide in a spectacular energy clash that ends in a massive explosion, with neither fighter gaining a decisive edge.

A Final Desperate Attempt

After Goku thoroughly humiliates him in combat, a furious Nappa turns his rage toward Gohan and Krillin, attempting to fire the Break Cannon at the helpless pair. Goku intervenes at the last possible moment, rocketing after Nappa and slamming him with the Kaio-ken Finish. The blow shatters Nappa's spine, ending his fighting career permanently and leaving him at Vegeta's mercy.

The Break Cannon has become a staple of Nappa's identity across Dragon Ball video games, appearing in nearly every title he features in. Different games have given it various names over the years: Lightning Cannon, Mouth Blast, Super Mouth Blast, Chou Makouhou, and Nappa Cannon, among others.

In Dragon Ball FighterZ, the move is integrated into a cinematic Meteor Attack where Nappa delivers a brutal gut punch before unleashing the beam at point blank range. In Xenoverse 2, players can learn Break Cannon by completing Nappa's Training lessons, making it one of the few mouth-based energy attacks available to custom characters.
