[4] Tom and Mary Bierbaum, who previously worked with Giffen on Legion of Super-Heroes, scripted the series over his plots and pencils for its run.

[4] After learning that sales on the series were "plummeting", Giffen approached DC and asked them to cancel The Heckler and leave #6 as the final issue.

[4] Stuart "Stu" Moseley, co-owner of "EATS", a skid row diner in the ghetto section of Delta City, fights the injustices and slightly goofy criminal element as The Heckler, armed only with his sarcastic wit and a brightly colored costume.

When wearing his costume, however, he seems to become a completely different person, endlessly confident and insanely daring with a talent for trickery and a smart-mouthed sense of humor that he uses to irritate, annoy and insult his foes until they usually pretty much defeat themselves in a style highly reminiscent of cartoon character Bugs Bunny (who Keith Giffen admits was a major influence on the creation of the Heckler[4]).

A leather jacket-clad overweight and middle-aged greaser who provides Stu with information on underworld activities and is regularly visited by the denizens of Delta City, including generals and monsignors, for advice on a vast variety of subjects.

McDougal bemoans the changing face of Delta City and mourns the loss of "42 Varieties", a donut shop which was demolished to make room for a McDonald's.

The Minx - A beautiful gun-toting loner in dark glasses and a mohawk who has a teenage daughter named Axi.

She hunts criminals in Delta City for the reward money, but there is a distinct personal motivation involved as they all tend to be men she previously dated.

A crusader for edgy and cynical art who despises mass-appeal media, he was to be the villain of the uncompleted seventh issue.

Delta City also appeared in Giffen's Doom Patrol series, where it is damaged by alternate reality versions of the team.

The Heckler makes a minor appearance in JLA: Welcome to the Working Week alongside Plastic Man and Ambush Bug.

In issue 12 of Book of Fate, Heckler makes a cameo in a bar called Warriors where he and some other lesser known heroes are talking about their crime fighting memories.
