Jūgo

Jūgo is a very tall, fit young man who has spiky orange hair, red-orange eyes, and a usually calm disposition. However, when affected by his murderous side, his skin turns dark, his irides become a pale yellow colour while his sclerae turn black, and he grows various weapons and appendages to suit his battle combat situation, as well as having a deranged look. Jūgo has a bracket-shaped symbol on his left palm. As a child, he wore a yellow shirt with blue shorts. When Jūgo was first introduced, he wore a pale blue shirt and pale green shorts. Later when Tamaki tried to find him some clothes, he wore black pants, a purple curtain he wore as a cape (Tamaki not able to find a shirt big enough for him), and brown sandals. After Taka had allied with Akatsuki, Jūgo was shown wearing an Akatsuki robe. Years later while working for Orochimaru, he developed noticeably more muscle and a stronger jawline. He also dons his hair in an up-do while keeping the sides short. Attire-wise he wears a ragged, dark-coloured cloak.

An outcast, Jūgo's random rage from his clan's power made him a danger to anyone around him, as they stood little chance of survival should he lose his temper. At one point, he became so angry that he destroyed a village and killed all of its inhabitants. This has caused others to label him as the "Scales", where anything could tip the balance. Cursing his existence, he took to secluding himself in caves, hoping to bring no one any harm. This lasted until he met Kimimaro, who was himself the last remnant of the Kaguya clan. Following Kimimaro, Jūgo allowed himself to be one of Orochimaru's test subjects in the hopes that he could be cured of his fits of rage.< However, amazed by Jūgo's ability to absorb natural energy to undergo various drastic physical alterations at the cost of mental state, Orochimaru's attempts to discover the origin of his clan's ability to use such power led him to the Ryūchi Cave, where he learned to use Senjutsu. Unable to enter Sage Mode, Orochimaru instead devised the cursed seals by combining his Senjutsu chakra and the mutative enzymes he isolated from Jūgo's blood. As Orochimaru was nearing time to swap vessels, Kimimaro took it upon himself to recover Sasuke Uchiha. Prior to leaving, Jūgo was visited by Kimimaro who explained the situation to him. Despite Jūgo's concerns for Kimimaro's health, he assured him that Sasuke is his legacy while thanking Jūgo for their friendship.
