Hitman

The Hitman comic book series by Garth Ennis and John McCrea follows the story of Tommy Monaghan, a tough-as-nails contract killer from Gotham. Thanks to a genetic mutation, he has gained telepathic powers and X-ray vision. Instead of becoming a superhero, he decides to keep doing what he does best—taking out targets for hire, whether they are criminals, demons, or even supervillains.
