The Atomic Sub

The Atomic Sub is an undersea adventurer from Big Bang Comics, an anthology series built as a loving homage to Golden and Silver Age superhero storytelling. Operating beneath the waves, the character embodies the classic pulp-era aquatic hero archetype alongside a roster of retro-styled champions.

Surfacing from the depths of Image Comics' love letter to classic superhero storytelling, The Atomic Sub made their debut in Big Bang Comics #3 in 1994 — a Copper/Modern Age creation steeped in the spirit of comics' golden traditions. A recurring presence across Big Bang Comics and Big Bang Adventures for over three decades, this undersea adventurer shares the page with a remarkable roster that includes Ultiman, The Knight Watchman, The Beacon, and The Blitz — the kind of heroic company that signals a richly imagined shared universe. With 21 catalog appearances spanning 1994 to 2025, The Atomic Sub is a testament to Big Bang's enduring charm as a publisher's heartfelt tribute to the archetypal heroes that built the medium — well worth a dive for any fan who loves comics that celebrate comics.
