Chōza Akimichi

is the father of Choji Akimichi and former teammate of Shikaku Nara and Inoichi Yamanaka, and together they were the previous Ino-Shika-Cho trio. The kanji on his chest armor means "food".

Personality
Choza is the head of the Akimichi clan and was part of the first "Ino-Shika-Cho Trio" alongside Shikaku Nara and Inoichi Yamanaka, his name being the Cho part of the group name. He is seemingly a gentle and caring man with great wisdom and understanding of the world, and has deep love for his son, Choji. Like the rest of his clan, he had a large appetite, and was prone to eat everything on an entire page on the menu.

Chunin Exam arc
He made his official appearance, during the Chunin Exam Festival, sitting alongside his former team-mates who were talking about the fact that Inoichi had a daughter, and how troublesome that is, according to Shikaku, while Choza was looking at the menu only to order everything on the page that he was looking at. When Shikamaru came to pick up his dad, Choza invited him to come and eat with them.

Invasion of Konoha arc
He made his next appearance during the end of the Konoha Invasion arc using the Super Multi-Size Technique, to trample some Sound Shinobi and later met up with Inoichi and Shikaku to reunite the original Ino-Shika-Cho Trio.

Invasion of Pain arc
He and Choji, along with a third, un-named member of the Akimichi clan and other re-enforcements are seen during the Pain's invasion, helping Kakashi by squashing the Asura path. During a failed attempt to defeat the Deva path with Kakashi and Choji, Choza is seemingly killed while protecting Choji from Shinra Tensei. Later it is discovered that Choza is still alive but needs to be brought to the hospital immediately, which causes Choji to cry in joy.

Abilities
Like his son and the rest of his clan, Choza used the special technique that allows him to change calories into chakra. As the leader of his clan, it is highly logical that he is skilled in all his clan's secret techniques. With this he has been seen using both the Super Multi-Size Technique, the Human Bullet Tank and the Partial Multi-Size Technique, which all revolved around the clan's special ability to increase the size of their various body parts.
