This is a secret jutsu passed down in the Akimichi clan that expands the user's stomach. This jutsu increases the user's body size by using up the user's food energy, converting calories into chakra. Akimichi clan members tend to eat fattening foods and have large physiques in order to support this technique.

After the user swallows a great amount of water to make themselves into a human-sized ball, they tuck their limbs inside their clothes and use chakra to propel themselves into a powerful roll. This is an excellent technique to use against Water Release users as it not only nullifies their attack but also turns it against them.

Name: Butterfly Bullet Bombing (蝶弾爆撃, Chōdan Bakugeki; English "Butterfly Bombing", Viz "Butterfly Bomb")
Type: B-rank, Offensive, Short range (0-5m)[1]
Users: Akimichi clan
Debut (Anime): Naruto Episode 114
Debut (Manga): Chapter 114

This technique is used in combination with the red Akimichi food pill (also known as the chilli pill), which burns away all of a ninja's excess fat and converts it into chakra. Because the members of the Akimichi clan tend to be overweight to support their jutsu, this pill can give them 100 times their normal chakra level. However, anyone who eats it will die unless given medical attention as described in the Nara clan's medicine book soon after. To perform the jutsu, the clan member simply channels all their chakra into one hand and punches the enemy, releasing the chakra on contact. The subsequent impact not only produces a sizable crater, but is almost guaranteed to kill the one on the receiving end.

Users: Akimichi Clan
Debut (Anime): Naruto Episode 114
Debut (Manga): Chapter 189

Like the standard Multi-Size Technique, this jutsu expands the body, but expands parts of the body as opposed to just the stomach. Skilled clan members can alter the size of their body to a large scale with little trouble. Those with lesser skills can use the Three Colored Pills to do the same. With the larger body parts, the user's strength increases proportionally. In Part II, Choji has mastered this technique to the extent that he can use it almost instantly.

Name: Spiked Human Bullet Tank (肉弾針戦車, Nikudan Hari Sensha; Viz "Spiky Human Juggernaut", English TV "Spiky Human Boulder")

This jutsu is basically the same as the Human Bullet Tank, but Choji wraps himself in kunai tied to strings to make it more damaging. The kunai also make him move faster since Choji has more traction than in his normal ball form. A variation of this jutsu is to use one's hair to wrap around the user's body if it is long enough as shown during the battle against Kakuzu and Hidan.
