Animal Man was a comic book ongoing series published by DC Comics and starring the superhero Animal Man. The series is best known for the run by writer Grant Morrison from issue #1 to #26 with penciller Chas Truog who stayed on the series until #32. Almost all of the series" writers and artists were part of the British Invasion of comics. Animal Man was innovative in its advocacy for its use of themes including social consciousness (with a focus on animal rights), metaphysics, deconstruction of the superhero genre and comic book form, postmodernism, eccentric plot twists, explorations of cosmic spirituality and mysticism, the determination of apparent free will by a higher power, and manipulation of reality including quantum physics, unified field theory, time travel and metafictional technique. The series is well-known for its frequently psychedelic and "off the wall" content.
