He has quite a large body, and he easily has the largest body in weight among Baraggan's Fraccion. His Hollow mask consists of a thick helmet with short tusks protruding from the sides. He has wavy, short blond hair and four short squiggly lines descending from each of his dark red eyes. He also has a jagged, chipped tooth protruding from the lower left side of his mouth.
Nirgge, like his fellow Fraccion, is respectful and worshipful towards Baraggan. Aside from that, it is difficult to discern his personality to a full degree, though he appears to enjoy fighting and is confident in his abilities, if not arrogant, like most Arrancar.
At some point, Nirrge, a yet-to-be classified class of Hollow, was found by and turned into an Arrancar for the latter's army, or he may have initially been a servant of Baraggan who survived Aizen's first attack on Las Noches when the Vasto Lorde was the king of Hueco Mundo. Regardless of his origins, Nirrge became a Fraccion of Baraggan and quickly developed a strong sense of loyalty to him.
