Caca

Caca is a charlatan who cons poses as a divine force. He appears throughout many RPG games in the Scrimmy Bingus franchise. 
Caca claims that he was possessed by a divine spirit called the Congus, who then imbued him with power over nature. In order to manifest this fake power, Caca uses Wongus, the Scrimmy Bingus franchise's version of Wicca. Caca has set up an apartment meant to fit the aesthetic of a psychic's shop, and he uses a variety of light and sound rigs hidden throughout the apartment to create displays and shows that make it appear that he does indeed possess a divine spirit. Caca also claims that Congus has made a dire prediction that the earth will be destroyed unless he is "fed" souls, which is apparently done by sacrificing one's life savings and all one's possessions to Caca. 
Because of the high quality of smoke and mirrors that Caca is in possession of, he has amassed a very large following of cultists called Caca Fans. These fans have been given evidence to Caca's lies on several occasions, with thorough investigations being done by police forces into his apartment that unveiled his deceptions. Despite this, many of the Caca Fans believe that if they continue to have faith in Caca and if they keep pretending that Congus is real, Congus will actually come into existence and Caca will actually be possessed. Their reasoning is that since many other deities exist throughout the universe, one is to reason that new ones can also be created with enough willpower.
