Jack Staff

Jack Staff is a British superhero created by comic book writer/artist Paul Grist. He is billed as "Britain's Greatest Hero". It's known for being in the style of an anthology title and for its multi-linear plotlines. He first saw print in comics published by Paul Grist's Dancing Elephant Press, and is now published by Image Comics. Comics International began exclusive publication of a monthly four-page strip featuring the supporting character Ben Kulmer (the Claw); this started in #185 of the magazine and was set to run for twelve episodes. These strips have since been reprinted by Image Comics in a special.
