I've always been fascinated by how fans try to put a graceful (or gloriously messy) bow on apocalypses — theories about how the calamity ends are some of the most creative pieces of headcanon out there. People love filling in the blanks when creators leave endings ambiguous or bleak, and those theories range from bittersweet survival to cosmic resets. Broadly, they cluster into a few fun categories: cyclical rebirths, clever technical reversals, moral or emotional reckonings, negotiated truces, and meta-level reveals that make the apocalypse itself a story device. I’ll walk through the ones I see most often and the fandom examples that inspire them.
Cyclical rebirth is a huge favorite. Fans of 'Dark Souls' have long argued that the Age of Fire and Age of Dark are part of a loop — the calamity ‘ends’ when someone either links the fire or lets it fade, but the world keeps spinning in new permutations. Similarly, readers of 'The
Wheel of Time' speculate about patterns and the Turning of the Wheel as an inherent reset: the Last Battle is tragic but the Pattern rewrites itself. Another take on rebirth is the “nature reclaims” theory, very common in 'Fallout'-type spaces: human civilization falls, then centuries later survivors reinterpret ruins as myth and rebuild differently. That ending is melancholy but hopeful — the calamity ends not in a supernatural finale, but in slow adaptation.
Then there are the technical or “hack it” theories where some lost tech or hidden cure undoes the apocalypse. In fans’ discussions around 'The Last of Us', there’s the hopeful-but-controversial idea that a cure might be finally synthesized, or that some radical surgical/tech intervention reverses the infection’s worst effects. For sci-fi works, the simulated-universe or time-loop theory pops up: the world resets because someone reboots the simulation, or a lone time traveler fixes one pivotal choice. People apply this to everything from dystopian novels to anime — think of how discussions of 'Neon Genesis Evangelion' or 'Steins;Gate' revolve around rewrites of reality as an “ending” that undoes the calamity, for better or worse.
More emotional resolutions also get a ton of love. Fans propose that the apocalypse resolves when a central character sacrifices themselves, making peace with an ancient power, or convincing the monstrous Other to coexist. In 'Attack on Titan' discussions, for instance, a big faction of fans hoped (and theorized) that reconciliation or mutual understanding could avert eternal ruin rather than a curt defeat. Then there’s the negotiated peace theory — the monsters or gods are reasoned with, imprisoned bargains are renegotiated, or humanity pays a price to seal the wound. And my favorite wildcard is the meta-theory: the calamity ends because the story ends. Fans joke that the author pulls a switch — a deus ex machina, an unreliable narrator exposed, or a reveal that the whole apocalypse was a test or plaything of higher beings. It feels cheeky, but it’s oddly satisfying to imagine fiction closing its own loop.
I love how these theories reflect what people want from an ending: closure, rebirth, justice, or complexity. Some fans cling to hopeful fixes, others prefer ambiguous cycles, and many enjoy the tragic beauty of an unresolved world. No matter which camp you’re in, the variety of ideas — from tech saviors and
time loops to bargains with gods and slow human renewal — shows how alive fandom creativity is. Personally, I’m always drawn to the bittersweet rebuilds: give me broken cities, stubborn survivors, and the first small shoots of green pushing through concrete — that’s a calamity ending that feels earned to me.
