Arale Norimaki's secret weapon from the Dr. Slump crossover. This android girl takes a deep breath and screams her signature greeting "N'cha!" with enough force to level buildings. Powered by her battery, not ki.
The N'cha Cannon is one of the most unconventional attacks to appear in Dragon Ball, which makes sense given its origin in Akira Toriyama's earlier comedy series Dr. Slump. The technique is simple: Arale Norimaki, the robot girl built by Dr. Senbei Norimaki, takes a massive breath and then screams her favorite greeting at maximum volume. The word "N'cha!" is amplified by Arale's android body into a focused blast of destructive force that functions like a Mouth Energy Wave.
Unlike ki-based attacks, the N'cha Cannon draws on Arale's battery power rather than life energy. This means repeated use or using it when her battery is low can drain her completely and leave her immobile. The cannon also only works with greeting words, an oddly specific requirement that fits the absurdist logic of Dr. Slump perfectly.
Arale and the N'cha Cannon crossed into Dragon Ball territory during Goku's original adventure, when he visited Penguin Village and encountered the pint-sized robot. But the technique's most memorable Dragon Ball appearance came during Dragon Ball Super, when Arale showed up on Earth and caused chaos that even Vegeta could not handle. She demonstrated a powered-up version called the 100x N'cha Cannon that proved absurdly powerful.
The Dragon Ball Super episode featuring Arale played the crossover for comedy, leaning into the fact that Arale operates on Dr. Slump's gag manga logic rather than Dragon Ball's power scaling rules. She was effectively invulnerable and impossibly strong, not because of any training or transformation, but because she comes from a universe where comedy overrides physics. The N'cha Cannon was the perfect expression of that: a greeting powerful enough to challenge gods.

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....

Dragon Ball handed us a protagonist with no history and the internet named him John Dragon Ball. So we built him somebody to talk to....
Arale is not the only character who can perform the N'cha Cannon. Obotchaman, built by Dr. Mashirito using Arale's blueprints, possesses the same capability. He used the technique to defeat Dr. Mashirito in the "Who's the Strongest in the World?" tournament within the Dr. Slump series. In Dragon Ball Fusions, fusion characters Arale 18, Towale, and Towane can also use the technique, blending Arale's gag power with other characters' abilities.
The N'cha Cannon occupies a unique niche in Dragon Ball's technique library: it is simultaneously one of the silliest and one of the most powerful attacks ever shown, a reminder that Akira Toriyama never stopped being a comedy writer, even when crafting one of the most influential action franchises in history.

Yes. Arale and the N'cha Cannon crossed into Dragon Ball during Goku's original adventure when he visited Penguin Village, and the character returned in Dragon Ball Super. Akira Toriyama created both series, allowing his Dr. Slump cast to appear as official crossover guests within the Dragon Ball continuity.
