Without going into extensive details, Adventure Comics has a long history which includes runs of Supergirl, members of the JSA, Superboy and the Legion of Superheroes, The Spectre, and Dial H for Hero! This unlikely team of heroes (the 2nd iteration), fights crime as any good hero does, and sometimes things get a bit crazy, like when Grockk (son of the devil) shows up and decides to take over the Earth! It’s up to Vicki Grant (Puma/Sulphur) and Christopher King (Enlarger Man/Brimstone) to stop him!
These new stories were written by Marv Wolfman (who’s no stranger to the macabre having written the Tomb of Dracula!). Wolfman is one of those writers who can tackle any genre, and he’s proved it over the decades continuously. The art is by none other than Silver Age stalwart, Don Heck (co-created Sunfire, Hawkeye, Black Widow, etc.)! The letters are by John Costanza. The cover is by the always awesome George Pérez!
