Binolt

Despite being a Blacklist Hunter, Binolt is also a high-class criminal, wanted for committing numerous acts of murder without any apparent concrete justification. He is apparently a hardened cannibal, who loves to rip apart and eat his victims. His preferred 'prey' are young women aged between 20 and 25 years (22 being the most sought after prey).

Appearance
Binolt has short, spiky hair and a bony face set with bulging eyes and serrated teeth, giving him a typically ferocious appearance of a criminal.

Background
Binolt is a shy and lonely character, who hates other humans as a result of a traumatic event from his childhood, when he came across a woman's purse that had fallen on the ground in a back alley. Wishing only to do a good deed without asking for a reward, he attempted to return it to the woman, only for her and her boyfriend to assume HE was the one who stole it simply because of his appearance of a typical street brat--scruffy and dressed in rags. They promptly beat him up and left him lying broken on the alley ground. From that moment on, Binolt began to hate other humans, which most likely led to his becoming a mass murderer.

Greed Island arc
Binolt first appears stalking Gon, Killua and Biscuit shortly after the latter offers to take the boys under her wing. He waits for Biscuit to break from the group (in actuality, Biscuit lured him out) and attacks her, cutting her hair only to learn of her true age and power when he uses his ability. He promptly challenges Biscuit to a bare-handed match, only to be easily overpowered by the more experienced hunter.

Biscuit offers Binolt a deal, if he helps train Gon and Killua by dodging their attacks for two weeks, she'll let him go, with the stipulation that if he loses before the time limit, she will kill him. Binolt agrees, confident in his ability to defeat the younger Hunters, only for Gon and Killua's natural talent to soon allow them to overtake him.

By the end of the two weeks, Binolt realizes he's reached his limit and surrenders, asking them to finish him off. Instead, Gon thanks him for his aid in training them, touching the serial killer. Binolt asks Biscuit to let him go so that he can turn himself in to the Hunters Association Authorities. Biscuit agrees and Binolt leaves, presumably to turn himself in and atone for his crimes.

Nen Ability
By cutting hair with his favorite scissors and eating it Binolt can learn of any sort of physique-related information about his opponent. It is with this ability that he realizes Buscuit's true age. 比諾透
