Moya Triad

The Moya Triad or Moya Brothers are a trio of "ninja" (though they lack the skill of even the most feeble shinobi). The eldest brother named Aniki is the smartest, but that is not saying much. Aniki holds a grudge against Kakashi Hatake for coming to the aid of a girl he had been stalking. During episode 101, all try and fail horribly to get revenge, which consisted of hiccup poison in the food, ambush, and laughing darts. They each have a stylized haze cloud symbol on their headbands that almost resembles a question mark. They claim to come from.

Trivia
