Red Monsoon Triad

The Red Monsoon Triad is a rival gang of the Triple Threat and Agni Kai Triads, with whom they often engage in turf wars. The gang consists solely of waterbenders.

History
When Mako and Korra approached Skoochy in Central City Station for information regarding Bolin's whereabouts, he mentioned that all the triads, including the Red Monsoons, the Triple Threats, and the Agni Kais, were recruiting new members for "something big".

Trivia

 * The triad is a reference to typical 1920s American mobsters, such as those in the Prohibition Era.
