Gazelleman is one of the Gifters in the Beasts Pirates.

Gazelleman is a tall, muscular man with wide shoulders, a large chest, a thick neck, and a square jaw. He wears a skin tight dark shirt with a light colored stylized "G" with the letter's leg resembling a "z", with light colored long sleeves with a dark line through them. He also wears light colored gloves, a Gifter's cape and cowl, and fishnet stockings over his gazelle like legs.

Like many other people, he has a distinct laugh: "Hohohoho".
