King Peacock is a devoutly religious character. In fact, he is the most devoutly religious major character in the Top 10 comics. He belongs to the ancient and relatively obscure pre-Islamic Yazidi (or "Yezidi") religion. There is considerable confusion and ignorance among King Peacock's fellow police officers about King Peacock's religion. A number of them routinely refer to him as a "devil worshipper." He may contribute to that impression somewhat through his own incomplete or inaccurate references to his religion.
King Peacock was one of the stars of an ensemble cast of Neopolis police officers whose stories were chronicled in the colorful and critically-acclaimed Top 10 comics written by Alan Moore and published by America's Best Comics. The original stories were illustrated by Gene Ha and Zander Cannon. The original Top 10 series ran for 12 issues, and has since been followed up by two additional 5-issue limited series, a graphic novel and a few other stories set in the same universe.
Regardless of what King Peacock or his fellow police officers in the Neopolis Police Department's Tenth Precinct say about Yazidi religious beliefs, either because they are unknowledgeable, joking, intentionally disingenuous, or because author Alan Moore does not know any better, real-world Yazidis are not Satanists or devil worshippers.

King Peacock, as is typical of real-world Yazidis, is a sincerely religious and remarkably ethical, morally-upstanding person.
King Peacock also happens to be one of the most respected and most effective police officers in the 10th Precinct.
In addition to being a devout practitioner of his own faith, King Peacock also demonstrated a remarkable knowledge about other religions. This was evident when he explained to other police officers the nature of the ancient gods that they met during a homicide investigation. King Peacock was the only officer who knew that the "murder" of the Teutonic god Baldur at the hands of Lokk (Loki) was not something they really needed to worry about, because it is a symbolic story that the Teutonic gods repeat every day, with Baldur always coming back to life without permanent harm.
