Mo

is a shinobi from the Moyagakure, and part of the Moya Triad.

Background
While they do have some ninja skills, Mo and his team prefer doing peculiar things to attract women. Aniki once tried to seduce a woman, who didn't like it, and Kakashi Hatake saved her. This angered Aniki and his team-mates, making them want to kill Kakashi.

Abilities
He, like his team-mates, would use poison to secretly attack their enemies. Though he claims to be a ninja along with his comrades, he has almost no ninja skills.

Part I
While trying to exact revenge on Kakashi Hatake, their endeavours all fail comically.

Trivia

 * Although his real name is not given, when posing for the Moya Triad, he gave the katakana, which led him to be given the unofficial name "Mo".
