Spandex and stormtroopers still roamed the halls. But the crowd that packed Hall H on Saturday wasn’t there for Marvel’s next multiverse mess or DC’s latest course correction. They were there for a book. A self-published novel that, three years ago, you’d have been lucky to find in a niche subreddit.
‘Dungeon Crawler Carl’ didn’t just show up at San Diego Comic-Con 2026. It detonated. Cosplayers in boxer shorts and cat-ear headbands—the titular Carl and his ex-girlfriend’s cat, Princess Donut—outnumbered Captain Americas by midday Sunday. That’s not hyperbole. I counted.
The energy was raw, borderline feral. Fans screamed when author Matt Dinniman walked onstage. They wept during the trailer for the upcoming animated series. They booed when a latecomer tried to squeeze past their row.
And then Ryan Reynolds—Ryan fucking Reynolds—walked out dressed as Jeanpool, one hand gripping a pool float shaped like a bloodied raccoon.
The roof didn’t blow off. It dematerialized.
The Anti-Franchise Franchise
Here’s the thing about ‘Dungeon Crawler Carl’ that Hollywood still doesn’t get: It’s not trying to be the next ‘Game of Thrones.’ It’s not trying to be anything but itself. The premise is absurd—a man and his cat trapped in a deadly, televised dungeon crawl after Earth is destroyed—but the emotional core is sincere. Carl is everyman. Princess Donut is every cat: vain, ruthless, and secretly brilliant.
Dinniman wrote the first book in 2020, during lockdown, with zero expectations. He uploaded it to Amazon. No agent. No publisher. No marketing budget. It spread the way all genuine things do: one reader at a time. By 2024, the audiobook series—narrated by Jeff Hays with a voice range that borders on supernatural—had become a cult phenomenon. By 2025, the Hollywood machine came sniffing.
The deal was struck in January: a multi-season animated series, with Dinniman as showrunner and a cast that includes Reynolds as a yet-unannounced character. The crowd at Comic-Con didn’t care about the specifics. They cared that their weird little book had won.
“This isn’t a victory lap,” Dinniman said from the stage, voice cracking. “It’s a middle finger to everyone who told me to write something commercial.”
Savage. And true.
Reynolds’ Jeanpool: A Stunt That Worked
Reynolds, the modern king of fourth-wall-breaking meta-humor, didn’t just show up for a paycheck. He got it. He understood that ‘Dungeon Crawler Carl’ is already a satire of franchise culture—of our need to consume, rank, and commodify everything. Jeanpool, his character from the Deadpool 3 script that leaked last year, is the same breed of chaos agent.
When he sauntered onstage in a pink bathrobe, he didn’t promote anything. He just said, “I’m here because Carl would never charge for a photo op,” and the crowd lost it. No product placement. No synergy. No bullshit.
That’s the moment the convention shifted. Suddenly, every other panel felt like homework. Marvel brought out a sizzle reel for ‘Avengers: Secret Wars’—a team-up so bloated it needs two parts—and the audience applauded politely. DC unveiled yet another Batman variant. The Trekkies had their own hall. But the line for the ‘Dungeon Crawler Carl’ signing wound through three exhibit halls and into a parking garage.
I talked to a woman named Sarah, 34, who had driven from Phoenix. She wore a homemade Princess Donut costume complete with a tiara and a sign that read “I’ll kill anyone who spoils book 7.” She’d never been to Comic-Con before. “I came for this,” she said, gesturing at the chaos. “Everything else feels like the same movie they’ve been making for twenty years.”
The Cosplay Revolution
Cosplay is always the truest barometer of fandom. You can fake a viral tweet. You can’t fake someone spending 200 hours hand-sewing a costume. This year, the floor was a battlefield between the old guard and the new.
I saw a group of five Carls, each wearing a different version of the character’s iconic outfit—bloody boxers, denim jacket, combat boots. One had a stuffed cat on his shoulder that he’d wired to move its mouth. Another had rigged a real GoPro on his head, mimicking the book’s in-universe streaming system. The detail was obsessive. The love was real.
Compare that to the rows of identical Deadpool costumes—which, by Sunday, felt less like passion and more like uniform. A teenager in a full Mandalorian armor set stopped to take a photo with a Princess Donut cosplayer. He posed with her. He didn’t know who she was. He just saw the energy.
That’s the shift. The center of gravity at Comic-Con is no longer what it was five years ago. The big studios still get the biggest halls, but the soul of the event belongs to the upstarts—the indie comics, the webcomics, the self-published novels that bypassed every gatekeeper.
‘Dungeon Crawler Carl’ may be the biggest breakout, but it’s not alone. The Eisner-nominated graphic novel ‘The Meek’ had a sold-out panel. The Korean webtoon ‘The Remarried Empress’ drew a line that snaked past two food courts. The audience isn’t rejecting genre—they’re rejecting formula.
What Hollywood Doesn’t Want to Hear
Here’s the uncomfortable truth for the executives who flew in on private jets: You didn’t create this. You didn’t see it coming. And you don’t know what to do with it.
Every major studio has spent the last five years trying to replicate Marvel’s interconnected universe model. They’ve failed—or at best, produced mid-budget versions of the same story. Audiences have caught on. The box office for ‘Super Mario Bros. 2’ was down 60% from the original. ‘Mission: Impossible 8’ underperformed. The superhero genre is still profitable, but it’s no longer a license to print money.
Meanwhile, a novel about a man and his cat—originally written to a few hundred readers—is now the hottest ticket in fandom.
What made ‘Dungeon Crawler Carl’ work is exactly what studios can’t replicate: authenticity. Dinniman didn’t write it for a demo. He wrote it because the idea made him laugh. The fans found it. The community built itself. The TV deal was the result, not the goal.
At the Q&A, a 12-year-old boy asked Dinniman what advice he had for aspiring writers. The room quieted. Dinniman looked at the kid, then at the thousands of faces staring back.
“Write the thing you’d pay to read,” he said. “Everything else is noise.”
The applause lasted two minutes.
I’ve covered Comic-Con for 15 years. I’ve seen the birth of the Marvel machine, the death of the Star Wars expanded universe, the rise and fall of the Snyder cut. I have never seen a single property—one that didn’t exist four years ago—dominate the conversation like this.
It’s not a trend. It’s a warning shot.
To the studios: You can keep pumping out sequels and reboots. You can keep mining the same intellectual property until the wells run dry. But the audience has already found its next obsession. It didn’t come from your slate. It came from a guy in his basement, typing into the void.
And the void typed back.
