2. Tommy Monaghan
(Hitman, DC Comics)
For me, Tommy Monaghan is an all-time top ten favorite DC character.
He was funny, he had heart, he was written by Garth friggin’ Ennis. What’s not to love? Tommy was a Gulf War Veteran living in The Cauldron, the only neighborhood in Gotham so bad that not even Batman bothers to go there. He served out his days doing jobs as a hitman for whoever would foot the bill.
But on one occasion, he ran into an alien parasite named Glonth, who bit into his spine and drank from him like a silly straw. Afterward, Tommy woke up with superpowers. He had limited telepathy and x-ray vision. In his subsequent solo series, Tommy used the powers almost never. He mostly just shot people. He was pretty good at that.
Hitman the comic was a dark comic masterpiece. To be honest, you could eliminate the words “dark” and “comic” from that previous sentiment, and it would still be true.
