Fugai

served as a knight in Haido's supposed "Utopian" army.

Abilities
Fugai could change her form to that of a werewolf-like monster, most likely due to the influence of the Gelel stone. In this form, Fugai could unleash loud howls which could destroy the surrounding area and defeat her foes.

Plot overview
She threatened Kahiko when trying to get information on the Stone of Gelel until Shikamaru Nara and Sakura Haruno arrived to intervene, but she managed to escape the two ninja. She was later killed when Sakura Haruno lured her under a set of large chimes that reflected her howl back at her, stunning her and leaving her unable to escape as the bars collapsed on her.

Trivia

 * Fugai's werewolf-like transformation, along with Ranke's Frankenstein-like transformation and and Kamina's bat-like one, could be perceived as parodies of three classic monster movies, namely Ranke as Frankenstein, Kamina as Dracula and Fugai as the Wolfman.
