Water Balloon Technique

Gengetsu creates a puddle of water mixed with oil beneath his feet, which he uses to produce bubbles that float up into the air. On his command, the bubbles launch themselves toward Gengetsu's enemy with such speed and force, they can cause great blunt-force trauma upon bursting.

Trivia

 * In Naruto Mobile, Gengetsu demonstrated the ability to create bubbles not only from a special puddle, but also from his own body.
