Jirōbō

Being the tallest member of Sound Four, Jirōbō was a large and imposing young man, towering over the rest of his teammates. He had fair-skin and narrowed, slanted orange eyes, usually depicted with a stern look on his face. Jirōbō had three tufts of orange hair on his head: a mohawk of sorts that ran down the middle and two similar styled tufts of hair at the side. His attire was a beige-coloured, sleeveless tunic with the symbol of the Sound Four on the hem and a pair of black, ¾ length pants that stopped just below his knees. He wore black arm-warmers, and a necklace that comprised of red circular pieces separating long, metallic pieces. He also wore traditional black shinobi sandals with mid-calf leg warmers covered by bandages, and a purple rope-like belt tied in an inverted bow around his waist. After being reincarnated, he looked like he did while alive with the exception the grey sclerae common in all the other ninja Kabuto Yakushi brought back.

In the anime, the Sound Four were originally prisoners of Orochimaru, forced to fight other prisoners to the death in battle royales. By surviving their respective matches, they proved themselves to be the strongest of Orochimaru's prisoners and as such were made his bodyguards. The Sound Four were at some point forced to accept Kimimaro as their leader, who easily defeated them all in battle and, because of his Shikotsumyaku abilities, was slated to be Orochimaru's next host body. Under Kimimaro their group was known as the Sound Five (音隠れの忍五人衆, Otogakure no Shinobi Gonin Shū, literally meaning: Hidden Sound Shinobi Five People). In the anime, the Sound Five assisted Orochimaru with assassinating the Fourth Kazekage and killing Shiore's team during the Chūnin Exams in Konohagakure. Kimimaro fell terminally ill after this, forcing him to withdraw from the group; he became ill at some unspecified time in the manga.
