[1] Hitman chronicles the exploits of Tommy Monaghan, an ex-Marine Gulf War veteran turned contract killer from the Cauldron, a lower-class Irish district of Gotham City.

A side effect is that his corneas and irises are solid black, indistinguishable from his pupils; the sight managed to unnerve Batman when he first saw them.

The inherited powers later come with limits, and Monaghan uses them selectively, both because of the difficulty of concentrating during an explosive firefight and the side effects of their extended use (which includes anything between a headache and a minor illness).

After gaining these powers, Monaghan decides to specialize in killing metahumans and supernatural threats, targets typically shunned by conventional contract killers as too dangerous or too expensive.

Despite his powers, Monaghan relies most on his creativity, improvisational abilities, and impressive gunfighting skills to take down a majority of his targets.

Hitman was first published as a 60-issue comic book series with one annual, one DC One Million tie-in issue, one crossover with Lobo and one appearance in Sovereign Seven #26.

John McCrea and I are actually doing four issues of JLA Classified, featuring what is effectively the "lost" Hitman story, the one that we never had space for in the monthly.

7: Closing Time (2012) Clark Kent is being interviewed about Superman's connection to notorious killer Tommy Monaghan.

Taking the conversation off the record, he tells a story of how the JLA intercepted a rocket which was filled with a new strain of the Bloodlines virus.

In the present day, Superman admits that he admires Tommy's moral courage in the extreme situation and mourns his passing.

The only reason he shows up is to check out Wonder Woman with his X-ray vision, after which he turns down their offer due to low pay.

Issue #1,000,000 was a part of the DC One Million storyline, which was a top vote-getter for the Comics Buyer's Guide Fan Award for Favorite Story for 1999.

"For Tomorrow", in issues #39–42, was a top vote-getter for the Comics Buyer's Guide Fan Award for Favorite Story for 2000.
