Insane Cultists are enemies found in EarthBound. They are first encountered by Ness in their Happy Happy Village. As members of the Happy Happyist cult, they wear blue robes and cover their faces with blue stockings; the only clothing they wear that is not blue are their black shoes and tie, and their white gloves and ball at the end of the stocking. Insane Cultists also carry around a paintbrush and bucket full of blue paint, which they use in their paint attack.
In the Japanese version of EarthBound, Mother 2, Insane Cultists did not have the ball on the back of their hat, but had the letters "HH" embroided in the base of their hat. Nintendo changed this in the English release, due to the risk of similarities with the KKK.
Ness has to fight at least four Insane Cultists during the course of EarthBound; after Ness receives the Franklin Badge from the imprisoned Paula, he exits the cabin and Pokey Minch makes him fight two Insane Cultists and a Spiteful Crow. Later, two Insane Cultists have to be talked to and promptly fought to pass through the praying Happy Happyists to reach Carpainter.
In battle, their only means of offense is utilizing a paint-based attack, and the only other move they can use is calling for the help of another Insane Cultist to join the battle. Fights with an Insane Cultist can be annoying sometimes, if the Cultist keeps calling for help, you will end up being overwhelmed. After the Happy Happyist cult is disbanded due to their leader coming to his senses after being influenced by the Mani Mani statue, they can no longer be fought, and most of them disappear.
