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.
Gazelleman is somewhat cheerful, especially when he brags about his speed. He has no remorse when kidnapping a child.
Gazelleman ate a Gazelle SMILE (ガゼルのSMILE,Gazeru no Sumairu?), which grants him the ability to transform his legs into that of a gazelle, enabling him to run at a great speed. He claims that he can go 200 kilometers in an hour. He appears to be lacking in stamina as he was wheezing with exhaustion after delivering Tama to Holdem.
Bikyaku Mawashigeri (美脚まわしげり,Bikyaku Mawashigeri?, literally meaning "Beautiful Leg Spin Kick"): Gazelleman first lifts his legs in the air and then spins to kick an opponent. It was first used in an attempt to kick Luffy but it was blocked by his arm.

Gazelleman and Batman were tasked with hunting down thieves when they came across Monkey D. Luffy, Roronoa Zoro, Tsuru, Kikunojo, and Tama at Okobore Town. While Batman shot arrows at Tsuru and the others after hearing Tsuru speak ill of Shogun Orochi, Gazelleman kidnapped Tama. He then reported to Holdem that he had captured the girl who tamed their baboon, and Holdem ordered Gazelleman to bring Tama to him. Gazelleman later brought Tama to Holdem as instructed, but he was extremely exhausted after the run.

Prior to the Fire Festival, Gazelleman joined Holdem in confronting the Okobore Town citizens concerning the Paradise Farm thefts. Sometime later, Gazelleman was tamed by Tama. During the Fire Festival, Gazelleman, Speed, and Daifugo went to Onigashima with Tama on Speed's ship. After arriving, the three distributed Tama's dangos to the other Gifters.
Gazelleman referred to himself as "Idaten" (韋駄天,"Idaten"?), the Japanese name for Skanda and a term used for fast runners.
