Spiked Human Bullet Tank

With its effectiveness raised several times by using it together with weapons, this technique is an enhanced version of the Akimichi clan's Human Bullet Tank.

One application of this technique first involves the user wrapping ropes with kunai attached around their body, after which the Multi-Size Technique is used. From that state, one switches over to the Human Bullet Tank. Using the kunai as spikes, the rotation power increases, and the attack power also drastically goes up.

In Part II, Chōji rapidly grows his hair out to wrap around his body in a manner similar to Jiraiya's Needle Jizō instead of using kunai. This results in far more spikes than the previous version as well as a shorter preparation time due to Chōji not needing to wrap kunai around his body.
