About this Issue

Detective Comics #225 (November 1955) introduced J'onn J'onzz — the Martian Manhunter — to the DC Universe, making it one of the most consequential single issues of the entire pre-Silver Age era. The character went on to become a founding member of the Justice League of America, standing alongside Superman and Batman as one of the seven originals, and has remained a fixture of the DC roster across every subsequent decade. The issue also occupies a genuinely contested place in comics-history debate: because it predates the debut of Barry Allen's Flash in Showcase #4 by nearly a full year, some historians argue it has as strong a claim as any comic to marking the start of the Silver Age, even though the mainstream consensus still awards that distinction to Showcase #4. Beyond chronology, the debut story fused 1950s science-fiction sensibility — the lonely alien stranded on an unfamiliar world — with the superhero genre in a way that felt fresh inside the pages of what was still primarily a Batman anthology, quietly planting the seed for DC's sci-fi renaissance.

In "If I Were Batman," a scientist’s accidental teleportation of a Martian to Earth sets off a unique journey when the alien, stranded after the scientist’s death, takes up a new identity as a police detective. Written by Joe Samachson and Jack Miller, with art by Joe Certa and inks by Joe Certa, this 1955 tale explores what it means to step into another’s shoes—literally and figuratively. The cover by Win Mortimer captures the mystery and intrigue of a Martian in a world not his own.

History

The debut story, 'The Strange Experiment of Dr. Erdel,' was written by science-fiction author Joseph Samachson and illustrated by Joe Certa, with the issue edited by Jack Schiff (though Whitney Ellsworth held the credited masthead role). Samachson was primarily a science-fiction writer by trade, which explains why the six-page story reads more as a mood-driven SF vignette than a superhero origin — Certa's art depicted J'onzz as notably more alien and sinister-looking than the softer appearance the character would settle into across subsequent installments. One persistent bibliographic dispute is worth noting: Rich Morrissey attributed the script to Jack Miller rather than Samachson, a claim disputed by other researchers; DC's own official credit in the 2007 Showcase Presents reprint collection assigns the writing to Samachson, which stands as the current canonical attribution.

Trivia · 8 facts

  • First appearance and origin of J'onn J'onzz (the Martian Manhunter), introduced in the back-up story 'The Strange Experiment of Dr. Erdel' — a title that also serves as the story's own name in some reprints.
  • Written by Joseph Samachson, illustrated by Joe Certa; actual editor was Jack Schiff (Whitney Ellsworth held the credited editorial role on the indicia).
  • The issue went on sale September 27, 1955, with a cover date of November 1955, published by National Comics Publications (the corporate name then used by DC Comics).
  • The debut story established J'onzz's core premise: accidentally teleported to Earth by scientist Dr. Mark Erdel's 'robot brain' machine, stranded when Erdel dies of shock, and forced to adopt the human alias John Jones as a police detective in the fictional Middletown, USA.
  • Also establishes J'onzz's foundational weakness — fire can sap his powers and threaten his life — a vulnerability that has persisted across nearly all continuities.
  • The Martian Manhunter's visual design was noticeably more angular and alien-looking in this debut issue; his appearance grew more humanoid and familiar in the issues that followed.
  • This issue marks the start of the Martian Manhunter as a recurring Detective Comics back-up feature, which ran continuously until Detective Comics #326 (1964) — nearly nine years — without the character ever earning a cover appearance on the title.
  • The origin story has been reprinted extensively, including: Secret Origins #1 (1961), World's Finest Comics #175 (1968) and #226 (1974), DC Silver Age Classics: Detective Comics #225 (1992), Millennium Edition: Detective Comics #225 (2001), Showcase Presents: Martian Manhunter Vol. 1 (2007), and Detective Comics: 80 Years of Batman Deluxe Edition (2019).
