Appearance

Mokuren has long black hair that covers his left eye and wears a red headband on his forehead. He later had left eye replaced with Kodama.

Personality

Mokuren is a ruthless and psychopathic killer. He intensely loves to kill women, and even refuses to do so with men, however, he later makes a special exception for Recca, who humiliates him in their "fight". After being so easily defeated, Mokuren swore revenge against Recca, and eventually comes to hate all the Hokage by association.
He will do whatever it takes to ensure that he comes out the winner, which includes blatantly lying and limitless cheating. During his fight with Kaoru, he played on his opponents memories of how they got along as partners, tricking Kaoru into turning his back on Mokuren. During his first battle with Tokiya, he promised to let Kaoru go, if Tokiya dropped his sword, but instead played dumb as if he never made any such claim, and continued to mercilessly assault Tokiya.
After he was defeated by various members of Hokage, he felt that they all looked down on him as if he was less than they were and embarrassed him. Mokuren also believed that all people were selfish, and that no matter what they said, they were always out for themselves in the end.
He is described as being like Mikoto's male counterpart.

Sealed Lands Saga

SODOM Saga

Abilities

Mokuren's madogu is the Kodama, which allows him to control the growth of plants, and even to allow the control of them from inside one's body. However, by infusing the madogu itself into the body of Mokuren, he was able to gain a fuller, more extensive control of plants.

Human Faced Tree: When the Kodama madogu was implanted into Mokuren's body, he gained the ability to transform his entire body into a large tree. His main method of attack in this form was whipping the enemy around with his branches, which could be quickly regrown if they were severed, unless they were frozen.

Dekumai/Dance of the Wooden Puppets: Mokuren creates puppet soldiers out of wood, and has them attack his enemy. Like most of his wood creations, they can regenerate if cut in half, or if limbs are severed. Mokuren hides in the middle of these dolls while they attack, covering himself in wood to resemble the dolls as to stay out of sight from his enemy.

Mokuren also has the ability to modify plants to make them better suited for battle, such as the sundew plant that usually eats insects, but has been grown to giant sizes by Mokuren to eat humans. His left arm also was able to turn into an iron maiden like venus fly trap.
