Kamira

Kamina was a knight in Haido's army. She could transform herself into a bat-like humanoid. In her human form, she displayed the ability to create something akin to a genjutsu to trap Kankuro, although it was broken off when he countered using Karasu. In her bat form, she could exude a thick cloud from her mouth, the effect of which seemed to purely be a smokescreen, as there seemed to be no lasting effects. Also, whilst in her bat form, she was extremely agile in the air. She fought Kankuro at the Land of Wind beach. She later did battle with Shikamaru Nara, who had trapped her with a multitude of exploding tags. Playfully teasing the Leaf ninja, she fell into his trap as she flew right into the clutches of Kankuro's Kuroari, and was sliced to pieces inside it, killing her instantly.

Trivia

 * Kamina's bat-like transformation, along with Fugai's werewolf-like transformation and Ranke's Frankenstein-like one, could be perceived as parodies of three classic monster movies, namely Ranke as Frankenstein, Kamina as Dracula and Fugai as the Wolfman.
 * When Kamina's genjutsu was broken, she turned into a swarm of bats. According to legends, Dracula could turn into a bat.
