Jabra is a dark-skinned man, with a Fu Manchu moustache, a pointed goatee, and long hair braided in a thick queue, that somewhat resembles a scorpion's tail. He also has a scar running vertically down his left eye. When in his half-wolf state, Jabra has an unusually large tail and snout. Jabra has the kanji for "wolf" tattooed on the front of his shoulder.
He had small pointed sunglasses on his forehead, small hoop earrings, and a black tie over his bare chest. He wore a black tangzhuang, that's white down the middle and always open, but somehow always covers his tattoo when in human form. He also wore a red sash around his waist over black pants and shoes. He basically resembles a typical Chinese Kung fu martial artist, commonly found in various pop culture and media.
In the Volume 44 SBS, it was revealed that when he was a child, Jabra already had his scar and resembled a typical martial arts student.
The Inu Inu no Mi, Model: Wolf is a Carnivorous Zoan-type Devil Fruit that allows its user to transform into a wolf hybrid and a full wolf at will. "Inu" is Japanese for "dog", and wolves are in the same family as dogs. In the Viz Manga, it is called the Mutt-Mutt Fruit Wolf Model. It was eaten by Jabra.
