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 secret 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, another application shows Chōji rapidly growing his hair out to wrap around his body in a manner similar to Jiraiya's Needle Jizō technique instead of using kunai, resulting in far more spikes than the previous version, less time to prepare for the technique due to near instantly producing the spikes instead of wrapping them around the body, as well as a superior defense for the user.
