Seaquant is a man of average height and build. He wears a light brown jacket with fur covering the shoulders and chest. He has spiky brown hair, which is kept up with a white head band.
When Seaquant came in contact with Gon, Kurapika, and Leorio he acted in a cordial manner. He has a blunt opinion on his employers the Zoldyck Family and their staff are in his opinion too uncanny for words.
Three years before the beginning of the series, Seaquant and about 100 of his henchmen[note 1] came to attack Kukuroo Mountain, but they were annihilated by Canary, a 10-year-old trainee attendant of the Zoldyck Family. Greatly shocked, he begged to become a servant of the Zoldycks. He is now good friends with Zebro, the old gatekeeper of the Zoldyck Family.
