Luppi, a male arrancar with effeminate features, is arrogant and boastful in battle. He insults and mocks his enemies by saying "Sorry!" and licking his lips. Luppi's skin is durable enough to block direct strikes from lieutenant-level combatants. When sealed, his Zanpakutō resembles a kodachi with a four-pronged silver tsuba, pink sheathe, and matching hilt. Luppi gains eight tentacles connected at one of the corners of an octagonal design and a bone cowl on his head.
