What Are Common Tropes In Runaway Hiccup AO3 Fanfiction Pairings?

Been scrolling through a lot of Steve/Garrett content lately, mostly on AO3, and a few patterns definitely jump out. A major one is the whole "Mob Boss AU" setup, where Garrett's mysterious, powerful background gets turned into a full-on criminal empire, and Steve's the principled cop or detective who gets tangled up with him. It plays on that tension between their canonical moral codes. There's also a surprising amount of Regency-era or historical AUs? Like, they'll be lords or rival gentlemen in some drawing-room drama, which honestly works better than I expected because of the inherent class and mannerism differences. And you can't escape the coffee shop or bookstore AU either—Garrett's the aloof, intellectual owner and Steve's the regular who slowly chips away at his reserve. One trope I see a lot but am kinda tired of is the amnesia plot. Steve gets hurt, forgets who Garrett is, and Garrett has to win him back all over again. It can be angsty, sure, but it's done so often it needs a really fresh take to stand out now. Honestly, the most interesting fics for me are the ones that subvert the expected dynamic, like making Steve the more worldly one and Garrett the socially awkward genius relying on him.

Popular fanfiction tropes for Hiccup and Jack? Man, they've got this wild underdog crossover energy that's impossible to ignore. The go-to setup is almost always 'Hiccup finds the frozen island after Toothless gets injured, and Jack Frost is the only one who can guide him through the magical blizzards.' It leans into Hiccup's tinkering brain meeting Jack's chaotic, ancient-but-childlike magic. You see a ton of 'sharing a dragon' stories—where Toothless becomes Jack's unofficial steed for ice-dancing in the clouds, which is just pure fun. Another huge one is the 'mutual outsider' trope. Both of them are misfits in their own worlds: Hiccup the scrawny Viking, Jack the forgotten Guardian. Fics love to have them bond over feeling invisible, but with a twist where Jack's invisibility is literal. There's this recurring beat where Hiccup is the first person in centuries to truly see him, and it's played for maximum emotional impact. It's less about romance immediately and more about this profound, soul-deep recognition that often spirals into something else. The 'Berk gets a winter spirit' scenario is everywhere, too. Jack causes harmless chaos in the village—ice sculptures, perpetual snowflakes—and Hiccup has to smooth things over with Stoick while secretly enjoying the mischief. It builds this 'us against the world' dynamic that's super appealing. Honestly, I get why these tropes are so sticky; they take the core loneliness of both characters and give them a mirror to see themselves in, which is a recipe for compelling stories, even the less polished ones.

Really depends on the kind of fic you're reading, but I'd say there's a couple of things that come up a lot. A huge one is the inherent absurdity of the setting getting twisted into something oddly serious—like, 'Epithet' is so silly at its core, but so many fics take a character's dumb epithet and make it a source of angst or trauma. The 'Prisoner 434' thing is a massive beacon for that. Then you've got the ensemble cast dynamic. Fics love throwing characters from different factions together in improbable domestic situations. Giovanni and his gang just hanging out with the museum kids, or Sylvie being forced into group therapy with Mera, that sort of thing. It's all about exploring the weird found-family potential. Crossovers with 'Anime Campaign' stuff show up a lot too, since that's the root material. People will pull in characters from there who never made it into the animated series, which can be fun if you know the lore. The downside is some fics assume you know everything and can get confusing. Also, a surprising number of fics lean into the 'food fight' aesthetic literally—like, entire stories structured around cooking competitions or cafe AUs, which feels appropriate given how many problems in the show are solved with or involve food. It's a specific vibe.

I love diving into 'Wings of Fire' fanfiction, and one of the most popular tropes is the 'Dragonets of Destiny Reimagined' theme. Fans love rewriting the original story with new twists, like what if one of the dragonets had a completely different power or backstory. Another big one is 'Alternate Universe' settings, where the characters are placed in modern times or even in space. The 'Enemies to Lovers' trope is huge too, especially with characters like Peril and Clay. And let's not forget the 'Missing Scenes' trope, where fans fill in gaps from the books, like what really happened during the War of SandWing Succession. These tropes keep the fandom alive and creative.

I've noticed Miu and Kokichi fanfics lean heavily into enemies-to-lovers, but with a very specific flavor. It's less 'we hate each other' and more 'we are two feral gremlins locked in a battle of wits and outrageous inventions'. The trope of 'mutual destruction as a form of flirting' is huge here—they're constantly trying to one-up or out-scheme each other, and the sexual tension is just off the charts because of it. You also see a lot of 'genius inventor x chaotic mastermind' dynamics. Fics often explore Kokichi stealing or 'borrowing' Miu's tech to cause mayhem, which forces them into these intense, close-quarters confrontations. A niche angle I adore is when writers flip the script and have Miu be the one to see through Kokichi's lies, not with empathy, but with cold, mechanical logic. She'll build a lie detector or analyze his speech patterns, and his usual tricks just... don't work on her. That creates a fascinating power shift. A lot of stories also use the 'hurt/comfort' trope, but it's never soft. It's more like 'I'm the only one allowed to break you' kind of vibe. They'll be vicious, but if an outside threat hurts the other, they become a united, terrifying front. It's possessive and messy and perfectly them. Maybe I've read too many, but I'm starting to think the real common thread is intelligence portrayed as a form of aggression. Their romance is basically a very loud, very horny debate.

Hiccup and Astrid's dragons getting together often mirrors the human romance, but I've always preferred when their bond develops independently from their riders' story. Toothless and Hookfang's dynamic has more potential than just following a pre-existing template from the main series. The 'enemies to co-conspirators' trope hits different with them—like, the story where Hookfang's natural aggression and Toothless's strategic thinking clash before they have to team up during a volcanic eruption that traps both their riders. It's not about friendship so much as pragmatic alliance evolving into mutual respect. A niche trope I love is when writers explore the sheer physicality of their relationship, the weight and size difference making simple interactions complicated. One fic described Toothless carefully maneuvering around Hookfang's spiky hide during a shared nap, all tiny movements and shifting scales. It grounds the fantastical in something tactile. Less successful are the attempts to directly parallel human romantic gestures; dragons aren't people, their affection shows through shared flight patterns or bringing each other bits of interesting prey, not flowers. The 'found family' angle with them protecting a clutch of stolen eggs or a wounded wild dragonling also works surprisingly well. It sidesteps the need for a traditional romantic plot and taps into their protective instincts, giving Snotlout and Hiccup hilarious side-roles as confused but supportive bystanders. That's the kind of thing I bookmark for rereading when I want something comforting but not overly saccharine.

Honestly, the whole 'enemies to lovers' framework is everywhere in Drarry fics, but it's the specific subversions that get me. Yeah, we've got the classic potion's accident forced proximity or post-war Ministry coworkers, but I'm a sucker for fics where the dynamic flips entirely—Malfoy as the reluctant war hero stuck with Harry's celebrity, or Harry seeking him out because he's the only one who gets the nightmares. There's a layer of shared trauma that a lot of authors mine really well, moving past schoolyard rivalry into something heavier. That said, I'm tired of the 'Pureblood Etiquette' trope where Draco teaches Harry about wizarding high society. Feels like a weird flex sometimes. I prefer when their connection is built on mutual, grumpy understanding, not Draco suddenly being a font of aristocratic wisdom. The best ones make their conversations feel like a careful disarmament.

I've always been drawn to 'How to Train Your Dragon' fanfics that explore Hiccup and Toothless’ bond through found-family dynamics. Many stories depict Toothless as more than a companion—he becomes Hiccup’s anchor, a sibling figure who fills the void left by Berk’s expectations. Some fics dive into alternate universes where Hiccup, estranged from his Viking roots, builds a new family with Toothless and other outcasts. These narratives often mirror real-world struggles of belonging, weaving themes of acceptance and unconditional love. One standout fic had Hiccup and Toothless founding a sanctuary for misunderstood dragons, symbolizing their shared journey from isolation to creating a home. The emotional depth in these stories resonates deeply, especially when authors highlight Toothless’ instincts to protect Hiccup, not just as a rider but as family. Another angle I adore is crossover fics where Hiccup and Toothless’ bond transcends worlds. In one story, they land in 'Avatar: The Last Airbender', bonding with Aang over shared experiences of being different. The found-family theme expands as they integrate into Team Avatar, with Toothless forming a playful rivalry with Momo. These crossovers often emphasize how their bond adapts to new environments, proving family isn’t bound by blood or even species. The best fics balance action with quiet moments, like Toothless curling around Hiccup during storms, echoing the comfort of a hearth.

Royai fanfiction tends to gravitate toward a few reliable tropes that really play into their specific dynamic. The 'Forced Proximity' setup is huge—stranded on a mission, sharing a safehouse, that kind of thing. It creates this pressure cooker for all their unresolved tension. You also see a ton of 'Post-Promised Day' fics exploring the aftermath, how they rebuild Ishval together while navigating their new, complicated relationship without the military chain of command as a barrier. Then there's the classic 'Undercover as a Married Couple,' which is just pure gold for the fandom. Watching two of the most competent, stoic people in Amestris pretend to be domestic is endlessly funny and revealing. 'Hurt/Comfort' is almost a given, given their history, but it's often Riza patching Roy up, with the roles rarely reversed, which says a lot about her character's endurance. A trope I find particularly resonant is the 'Unspoken Understanding.' Fics rarely have them confessing feelings in a standard way; it's all in the gestures—a shared glance over a map, her preparing his coffee exactly right, him finally securing her a desk job. The romance is in the service, which fits them perfectly. The tropes work because they amplify what's already in canon: duty, sacrifice, and a bond forged in fire and ink.

Ah, the 'How to Train Your Dragon' crossover rabbit hole! It's always a joy to see where people take Astrid and Hiccup. A big one is plopping them into the 'Avatar: The Last Airbender' world, especially as members of the Water Tribe. Their innate bond with dragons and the Sky Bison parallels is too good to pass up—imagine Hiccup tinkering with Water Tribe mechanics and Astrid becoming a fierce warrior under Master Pakku. It lets them keep their core identities while navigating a completely different elemental conflict. Another persistent favorite is crossing them into the 'Harry Potter' universe. Hiccup as a Ravenclaw or even a Hufflepuff with a shocking affinity for magical creatures makes so much sense, and Astrid as a no-nonsense Gryffindor who's initially skeptical of magic but becomes its most determined practitioner. Stories often have them as students or, more interestingly, as adults who bring Toothless into a wizarding world utterly unprepared for a Night Fury. The clash of cultures is the real draw for me. Some of the most creative ones I've stumbled upon are crossovers with 'Game of Thrones.' Berk's rough, Viking-esque society fits right into Westeros, but Hiccup's pacifist-leaning ingenuity and dragons completely upend the political and military landscape. These stories often focus on them as leaders of a new house, trying to survive the game while staying true to their belief that dragons aren't just weapons. It's a high-stakes scenario that tests their relationship in fascinating ways. For something a bit lighter, I've seen them integrated into the 'Percy Jackson' world as demigods or legacies. Hiccup as a son of Hephaestus is almost too obvious, but it works brilliantly for his inventor side. Astrid as a daughter of Ares or Athena sparks great internal conflict—honoring her warrior spirit but learning there's more to strength than just battle. The modern setting forces them to adapt in hilarious and touching ways, with Toothless causing chaos at Camp Half-Blood.
