Genbu

Genbu was a tortoise demon who worked under Hoshiyomi to recover the Naginata of Kenkon. He tricked Kagome by creating puppets identical Kagome's friends, Ayumi, Eri, and Yuka. Genbu and the other ninjas were killed by Miroku's kazaana. When he first appeared, he called himself Genbu of the darkness.

Appearance
Genbu has green skin, is bald, and pupiless yellow eyes. Like most demons, he has elf-like ears. Before his transformation, he wears a black shinobi shozoku, usually without the mask. After his transformation, the only change he takes is that he has a giant turtle shell replaces his clothes. He also appears to be the tallest and more muscular of the demon ninjas.

Abilities

 * Enhanced Strength: Genbu is a lot stronger than the other ninjas. He had lifted and thrown several boulders twice his size down a hill in a failed attempt to crush Akitoki.
 * Enhanced Speed: Genbu moves so quickly that he appears as a shadow while he's running.
 * Demon Ninja Doppleganger Technique: Using their enhanced speed, the ninjas can create shadow-like dopplegangers of themselves. They used it once on Sango, Miroku, and Inuyasha.
 * Shuriken: Genbu used one once to prevent Inuyasha from escaping.
 * Demon Ninja Darkness Puppets: Genbu created illusions of Kagome's friends to try to trick them into handing over the Ken blade. Genbu himself created the illusions, while Suzaku, Byakko, and Seiryu indirectly controlled the puppets' dialogue.
 * Transformation: During his fight with Inuyasha, Genbu had grown a giant tortoise shell around his body, and was able to withdraw in it.
 * Demon Ninja Spinning Demon Shell: Genbu withdraws in his shell and begins spinning rapidly to crush his opponents. He did this while fighting Inuyasha.
 * Crushing: Genbu used his massive body structure to try and crush Inuyasha against a cliff wall. 160px-Genbu_rocas.jpg

Personality
Genbu seems to be easily irritated, as he got frustrated with Suzaku on a couple of occassions for playing around and distracting his concentration.

Quotes

 * "Demon ninja darkness puppets: the puppets won't be affected by the aura, and they'll be able to steal the blade."

 * "It's your fault for making me lose my concentration!"
