The original line of Harrier titles were in the science fiction, adventure, and fantasy genres; as the company moved forward it focused more on alternative comics.

Harrier's alternative imprint, New Wave, featured a number of notable creators, including Eddie Campbell, Phil Elliott, Glenn Dakin, Paul Grist, Ed Hillyer, Rian Hughes, Trevs Phoenix, and Warren Pleece.

The success of Kevin Eastman and Peter Laird's Teenage Mutant Ninja Turtles led to a short-lived explosion of black-and-white independent comics in the United States in the mid-1980s.

That same year, Harrier published one issue of Lew Stringer's Brickman (a parody of Batman), which featured pages drawn by notable British creators Dave Gibbons, Mike Collins, Mark Farmer, and Kevin O'Neill, and an introduction written by Alan Moore.

1987 was Harrier's most active year, as it debuted the humor series !Gag!, Barbarienne (written by Lock), Eddie Campbell's Deadface, Grun, Nightbird, and Swiftsure vol.

That year Harrier also debuted its New Wave imprint — the first title published under it being Glenn Dakin and Steve Way's Paris the Man of Plaster, which ran for six issues.

The New Wave imprint featured Campbell,[8] as well as Glenn Dakin's work, in Paris, The Man Of Plaster (with Steve Way) and the anthology !Gag!.
