Jirobo (次郎坊 Jirōbō) is the physically strongest member of the Sound Four and the weakest overall, according to the other members of the Sound Four. His fighting style consists mostly of basic physical strikes supplemented with the ability to use his chakra to hold the earth solid. His physical strength is unbelievable, which is demonstrated when he holds up a mountain-sized Choji Akimichi when in Level 2 cursed seal form. He tears boulder-sized chunks of dirt out of the ground to throw, creates barriers by tearing up massive sheets of rock, and can drain chakra with his Chakra Absorption Technique. He dislikes it when Tayuya uses foul language or when she calls him "fat", and he always criticizes her when she does. Despite this, he proceeded to call Choji fat near-constantly during their battle. When in Level 2 cursed seal form, his skin becomes red, his mohawk becomes a mane down his back, his eyes turn black, and he gains ten times his normal strength. It is mentioned various time in the anime that he is almost always enormously hungry, and he can get the same energy from absorbing opponents' chakra that one would get from food, as well as vice versa. He was killed by Choji Akimichi during the Sasuke Retrieval arc with a fatal punch to the chest.
