Wind Release: Drilling Air Bullet

Shukaku takes a deep breath, distending his stomach, and punches himself in the gut, shooting large balls of compressed air and chakra at an opponent. As expected from a tailed beast, this attack is very dangerous as even the large Gamabunta was in danger from the attack. The power of this attack was more than enough to level an entire forest, as well as smash through several mountains and hills at the edge of the landscape.

Trivia

 * Shukaku is the only tailed beast known to use an actual jutsu as it's form of projectile. All other tailed beasts instead gather raw chakra to form Menacing Balls.
