Promethea is a comic book series created by Alan Moore and J.H. Williams III with Mick Gray, published by America's Best Comics/Wildstorm. Serialized in 32 issues on an irregular schedule from 1999 to 2005, the series explores Moore's ideas about art and magic, combining elements of superhero action, metaphysical theorizing, and psychedelic hallucination, all focused on the adventures of Promethea, a metafictional character that possesses magical power over the real world.
