Gallagher has brown hair, the front grown out long enough to cover his eyes slightly, and the back grown out to his neck. He has light stubble, and orange eyes. He wears a black suit with a white, unbuttoned vest over it. The crest of the Bloodhound Family is on the inside of the vest. He wears a red-pink tie. His sleeves are rolled up, revealing scars on his arm. His past is a mystery to most everyone. He takes his job of mixing drinks seriously.
