Enigma was published by Vertigo in 1993.

Enigma is a thought-provoking post-modern tale of self-discovery and sexual identity told against the backdrop of improbable super-heroes and villains. Michael Smith lives a meaningless life of routine and boredom. But when Enigma, his favorite childhood comic book hero, inexplicably comes to life, Smith finds himself on an obsessive crusade to uncover the secret behind his improbable existence. Teaming with Enigma's comic creator, Smith encounters an insanity-inducing psychopath, a brain-eating serial killer, and a suicide-inciting clown posse as his quest uncovers hidden truths about both his idol and himself.
