For decades, super-hero comics have masterfully crafted unforgettable cliffhangers. Picking just 10 of the most remarkable and influential ones is a daunting task, but by focusing on the titans of the industry, Marvel and DC Comics, we can highlight moments that not only kept fans eagerly returning but also shaped the worlds of comics, TV, and film.
1. Crushed Under Pressure
The Amazing Spider-Man #38, 1966 #31-33, 1966
The Comics Code Authority, a strict censorship body, was one of the super-heroes' greatest foes, often opposing cliffhangers because villains weren't punished within the same issue. Marvel's Spider-Man boldly defied this rule, letting villains escape to fight another day. Even in victory, Spider-Man faced nail-biting endings. One standout story (ranked as the second most beloved Spider-Man tale decades after its release) concludes with a jaw-dropper: Aunt May lies in the hospital, suffering from radiation poisoning caused by a blood transfusion from Peter. Desperate to save her, Spider-Man battles Dr. Octopus for the antidote. After defeating his foe, the lab collapses, burying Spider-Man under heavy debris. As water rises, the serum remains tantalizingly out of reach. (The next issue reveals his dramatic escape and last-second rescue.)
2. The Arrival of Galactus
Concerned that the super-hero craze might fade, Marvel's Stan Lee and artist Jack Kirby, co-creators of The Fantastic Four, introduced an unparalleled antagonist: Galactus, a towering, godlike entity who sustains himself by devouring planetary energy. The story's first cliffhanger delivers a chilling proclamation—Earth's impending doom. This pivotal moment revolutionized comic storytelling, inspiring countless tales where the villain is unveiled on the final page of the first issue, only to be thwarted over subsequent installments. Yet, few villains have ever matched Galactus's sheer menace.
3. "Brace Yourself... for My FINAL VENGEANCE!"
While not as groundbreaking, this remains one of my all-time favorite cliffhangers. The issue concludes with the grotesque Red Skull wielding the Cosmic Cube to swap identities with Captain America. Unaware of the switch, Sharon, Captain America's love interest, seeks protection from the imposter, believing him to be the hero. Meanwhile, the real Captain America is left with the Red Skull's terrifying appearance and the grim realization that his girlfriend now sees him as a monster. His concern isn't just for himself: "What will become of her," he wonders, "and all of HUMANITY... while the world's MOST DANGEROUS THREAT walks among us... as CAPTAIN AMERICA?!!" This concept later inspired films like Face/Off, but the comic executed it masterfully.
4. "You’re Actually a Junkie?"
The Comics Code Authority had strictly prohibited drug-related themes in comics. When Marvel tackled an anti-drug storyline in Spider-Man at the request of the U.S. Department of Health, Education and Welfare, it was denied the Code's approval. (This tale is explored in detail here.) Eventually, the rule was softened. However, the concept of a drug-using super-hero was unimaginable—until Speedy, Green Arrow's protégé and sidekick, revealed his addiction to his mentor. Speedy's confession stunned both Green Arrow and readers alike. As a respected Teen Titans member, his struggle with addiction was groundbreaking. Writer Denny O'Neill, who crafted impactful stories around Speedy's journey, later brought similar depth to Marvel's Iron Man, addressing alcoholism without downplaying its severity.
5. "Now It’s MY Time to Shine!"
Uncanny X-Men, 1979
A classic cliffhanger traps the hero in a dire situation, leaving readers eager to discover how they’ll escape. But some cliffhangers captivate for entirely different reasons. One of Marvel's most iconic moments occurred when the Hellfire Club ambushed the X-Men, crushing Wolverine under a building and defeating the rest of the team. Just as all hope seemed lost, Wolverine emerged from the sewers, battered but unbroken. "Alright, punks—you’ve had your fun!" he snarls. "Now it’s MY turn!" What followed? Readers had to grab the next issue to see how Wolverine dealt with his foes—and who could resist such a thrilling setup? This moment propelled X-Men to become America's best-selling comic, with Wolverine crowned as Marvel's most beloved character, the ultimate hero when stakes are high. This cliffhanger inspired countless imitations in comics and TV, including a memorable scene in Buffy where Giles stands as the last hope against Willow.
6. The Universe’s Final Hour
DC Comics revitalized their universe (and boosted sales) with Crisis on Infinite Earths, a series where a wave of anti-matter annihilated multiple parallel universes. Originally planned for 12 issues, the fourth issue ended with the universe seemingly obliterated, leaving readers with the cryptic line: "To be continued --?" Naturally, the universe was restored, rebuilt from the ashes. (This version endured until 2011, when another reboot refreshed the world—and sales once again soared.)
7. "I Executed It 35 Minutes Ago."
Alan Moore's Watchmen is often hailed as the pinnacle of super-hero comics, celebrated for its intellectual depth and even featured in university courses. Its antagonist, Ozymandias, a former super-hero, wielded not physical strength but unparalleled intelligence. In a chilling Antarctic showdown, he revealed his plan to teleport an "alien being" into Manhattan, annihilating half the city. When Nite Owl questioned the timing, Ozymandias delivered a jaw-dropping response: "Do you seriously think I'd explain my MASTERSTROKE if there remained the slightest chance of you affecting its OUTCOME? I did it thirty-five minutes ago." The next issue confirmed the devastation, cementing Watchmen as a groundbreaking departure from traditional super-hero tales.
8. "Could He Still Be Alive?"
DC Comics faced uncertainty with Jason Todd, the second Robin. Unpopular since replacing Dick Grayson, his fate was decided by readers in a bold move. Writers prepared two outcomes: one where he survived a bomb explosion and another where he perished. The readers voted for his death. Years later, Jason Todd returned to life, as super-heroes often do, thwarting the readers' grim decision. Meanwhile, Law & Order adopted a similar approach, letting viewers decide the fate of a villain, who was spared—proving perhaps that Batman fans are more ruthless.
9. Clark Kent’s Big Reveal
A cornerstone of the Superman mythos is the secrecy of his dual identity—even from Lois Lane, the woman he loves. Decades later, with Lois engaged to Clark, she remained oblivious to his super-hero alter ego. In a shocking twist, Clark finally disclosed the truth on the final page of a comic, leaving readers to ponder, "How will she react?" Surprisingly, Lois was thrilled to discover her fiancé was Superman. While fans took longer to process the revelation, it proved that even after decades, Superman could still deliver fresh surprises.
10. The Mask Comes Off
With Marvel's iconic heroes presumed dead, the Thunderbolts emerged as a new team, billed as "all-new heroes" and "the next Avengers." Their debut issue ended with a jaw-dropping twist: their leader, Citizen V, revealed himself as Baron Zemo, a notorious Nazi villain from Captain America. His teammates were unmasked as members of the Masters of Evil, longtime adversaries of the Avengers. Their scheme? Gain the world’s trust and then seize control. This twist is hailed as one of comics' greatest. While the original heroes eventually returned and Zemo was defeated, some of his cohorts found they preferred being heroes and switched sides.

Special thanks to commenter Kendall for catching the mistake in the Master Planner Saga issue numbers! While #38 was impressive, it doesn’t quite measure up to #33.
