He has quite a large body, and he easily has the largest body in weight among Barragan's Fracción (whereas Choe Neng Poww has the largest body in terms of actual size). His Hollow mask consists of a thick helmet with short tusks protruding from the sides. He has a wavy, short blond hair and has four short, squiggly lines descending from each eye and jagged, chipped teeth.
Nirgge is boastful, short-sighted, and demeaning. During his fight with Marechiyo Ōmaeda, he insults Ōmaeda's weight despite being of similar bulk himself. Like his fellow Fracción, he holds his master, Barragan, in high regard and refers to him as "his majesty". He is also somewhat lecherous, telling Ōmaeda he preferred fighting Rangiku Matsumoto instead of him. Despite this, he seems to be somewhat patient, as he never actually loses his temper unlike his comrade Ggio Vega. He appears quite bored in the fight with Ōmaeda, and waits until he has tired himself out by trying to cut through his Hierro before doing anything.
