About this Issue

House of Mystery #156 marks the debut of 'Dial H for Hero,' one of DC's most inventive Silver Age concepts: a teenager who dials H-E-R-O on a mysterious alien device to transform into a random superhero each time he uses it. The concept was durable enough to be revived three more times across decades, spawning new series in the 1980s, 2003, and 2012. The issue also represents a major editorial shift for the title, as the new feature displaced the Martian Manhunter from the headline slot he had held since issue #143, demoting J'onn J'onzz to backup status for the remainder of the run through issue #173. Together, the two co-features — Robby Reed's whimsical shape-shifting heroics and J'onn J'onzz's grim battle against the monsters of the Idol Head of Diabolu — encapsulate the range of Silver Age DC storytelling in a single pamphlet.

"Dial H for Hero" introduces teen genius Robby Reed and his extraordinary discovery: a mysterious dial that lets him transform into different superheroes by dialing "H-E-R-O." With art by Jim Mooney and lettering by Stan Starkman, this 1966 House of Mystery #156 delivers a fresh take on the superhero trope, as Robby takes on the Thunderbolt Gang—only to see their leader, Mr. Thunder, slip away. The cover by Jim Mooney captures the moment’s electric tension, setting the stage for what’s to come.

History

The issue carries a cover date of January 1966 and was published on November 18, 1965, under editor Jack Schiff. Writer Dave Wood scripted both the lead 'Dial H for Hero' story (14 pages) and the Martian Manhunter backup, with Jim Mooney providing pencils and the cover illustration. The 'Dial H for Hero' title itself is an explicit nod to the 1954 Alfred Hitchcock film 'Dial M for Murder,' a playful pop-cultural wink typical of the era. The entire original run of 18 Robby Reed stories through issue #173 was later collected in DC's black-and-white Showcase Presents: Dial H for Hero (April 2010).

  • First appearance of Robby's supporting cast: grandfather 'Gramps' Reed and housekeeper Miss Millie.
  • First appearance of villain Mr. Thunder (Erick Bolton), leader of the criminal Thunderbolt Gang; his real name is not revealed until issue #168.
  • In this debut story, Robby transforms into three hero identities for the first time: Giantboy, Cometeer, and the Mole.
