Hae is a short, gaunt man with thin, hairy arms and legs. His head looks unusually large compared to the rest of his body. He has pointed ears and big, round eyes circled by creases. His hair is short and dark, with two gray streaks departing from his temples. Hae's nose is so small only his nostrils are visible. His face is stubbly and he seems to miss a few teeth.
Hae's usual apparel is comprised of a light green scarf, a darker green coat with tucked sleeves, worn over a white shirt, a light brown, striped obi, gray knee-length pants and Japanese sandals (geta).
Not much is known about Hae's abilities, but the fact that he is a Floor Master is proof enough of his power and proficiency in Nen. Still, he was defeated single-handedly by Jed's followers. In a magazine held by Killua, Hae is depicted defeating an opponent much taller than him with a headlock, implying he is also agile and a capable martial artist.
Neck Lock (Nekku Rokku): Hae performs a simple choke hold to suffocate the opponent.
Kyuuketsu (possibly "Sucking Blood" or "Blood Donation"): A technique Hae performs with the help of what seems to be a blow dart weapon or a straw. Judging by its name, it is possible that it enables Hae to suck his opponent's blood through open wounds.
