Mo

is a member 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 teammates, 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. He appears to be very flexible.

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".
