Jugo appears to be calm and trusts Sasuke completely. He is very loyal towards Sasuke and fulfills his orders with no hesitation.
Jūgo is a tall, muscular young man who has spiky orange hair, red-orange eyes and a usually calm face. However, when affected by his murderous side, his skin turns dark, his irides becomes a pale yellow colour while his sclerae turns black, and he grows various weapons and appendages to suit his battle combat situation, as well as having a deranged look.
Jūgo is a very dangerous individual, enough to warrant the attention of other powerful ninja such as Orochimaru and Sasuke. He is able to understand and communicate with animals, such as birds, and is able to request them to help him accomplish tasks, such as acting as scouts or gathering information they have already witnessed.
