Artists included Kano, Leonard Kirk, Patrick Gleason and Dale Eaglesham.
The series' focus was the "H-Dial" that DC had first introduced in "Dial H for Hero" in House of Mystery in the 1960s.
There was a subplot involving Robby Reed (the main character from the original Dial H for Hero) that ran through most issues and led to the series' final storyline as he tries to find the H-Device.
After his powers kick in, Matt Allen agrees to help Robby Reed after Andrea is captured by the serial killer.
The series ends with the H-Device being sent back in time by Robby Reed where it is found by the Neanderthal from issue #11.
