Where Can I Find Arrow Fanfic With Crossover Superhero Plots?

I think the absolute top of the list has to be a crossover with the first 'The Flash' show that ran alongside 'Arrow' for years. CW's Flash, I mean. You can tell the writers had fun with it; there are dozens of episodes crossing over, and it spawned thousands of fic spin-offs. The ones where Barry vibrates Oliver into a wall to save him, or where Oliver is grouchy about magic and super-speed messing up his city, are classics. That dynamic of tech vs. powers, darkness vs. light, is basically built-in. For a deeper cut, some of the Batman crossovers on AO3 are surprisingly effective, especially when they lean into the street-level detective angle. I read this one where Batman shows up in Star City to investigate a drug shipment, and he and Oliver spend half the fic posturing at each other on rooftops before grudgingly teaming up. It tapped into the whole "two broody vigilantes, but one is way more traumatized" thing that fans love. That's a really common niche, but when done well, it feels like it could be an actual comic arc. A weird one I've got soft spot for: short fics crossing over with the Netflix 'Daredevil' series. It shouldn't work—different tones, different networks—but the Catholic guilt and no-kill rule of Matt Murdock clashing with Oliver's more lethal early-season methods creates amazing tension. I remember a fic where Foggy Nelson ends up defending one of Oliver's old victims in court, and Matt has to figure out who the Hood really is. That kind of legal drama mixed with vigilantism is pure catnip for a specific reader.

AO3's my usual haunt for that kind of thing. The tagging system is a lifesaver—you can filter for 'Crossover' and then add 'Peter Parker & Other Superheroes' or whatever dynamic you're craving. I've found some wild, fun stuff blending Spidey with the 'Daredevil' Netflix vibe, or even hopping over to Gotham. Sometimes the best finds are in the 'Marvel Cinematic Universe' fandom tag rather than a specific 'Spider-Man' one, because writers will just tag all the characters featured. Honestly, Tumblr's a mess for actual reading, but it's weirdly good for discovery. Writers will promo their multichapter crossovers there with moodboards, and you can follow a trail of reblogs to the actual story posted on AO3 or FanFiction.net. The latter site has a ton of older material, like pre-MCU crossovers with the 'X-Men' movies or even the Raimi trilogy meeting other heroes. The search function is clunky, but the sheer volume means there's gold if you're patient. Don't sleep on niche forums or dedicated Discord servers either, especially for specific pairings like Spider-Man/Iron Man team-ups. The rec lists there are curated by superfans who've already sifted through the mediocre stuff. My to-read list is mostly from those kinds of places, stuff I'd never have stumbled on with a basic tag search.

Finding Arrow fanfiction feels oddly tricky these days, since the show ended. I mainly stick to Archive of Our Own—the tagging system is unbeatable. You can filter by characters like Oliver/Felicity or Diggle & Oliver bromance fics, and sort by kudos or hits to see what's trending. There's still a steady stream of post-canon fix-its and 'what if Oliver lived' AUs that pull decent engagement. Sometimes I'll check FanFiction.net out of nostalgia, but the activity has definitely slowed. The 'Arrow' category there still has a deep back catalog of stories from the show's peak, though. Tumblr tags can surface some hidden shorter pieces or drabbles, especially for rare pairs, but it's more of a scatter-shot approach.

It depends on what you mean by 'best,' honestly. Are you looking for classic post-season-two Oliver and Felicity stuff, or the darker 'what if' scenarios that twist the show's premise? Most people will point you to Archive of Our Own first, and I get why—the tagging system is phenomenal. You can filter for completed works over 100k words, which weeds out a lot of the abandoned WIPs that plague other sites. But I have a soft spot for some older, dedicated LiveJournal communities. The quality there feels different; writers took their time with world-building, and the feedback was more substantive. A lot of those stories got migrated to AO3 eventually, tagged with things like 'Arrow Season 2 AU' or 'Slade Wilson Redemption.' Those are my personal favorites—they explore the moral grey areas the show sometimes glossed over. Don't sleep on FanFiction.net either, even though its search is a nightmare. The sheer volume means there are hidden masterpieces buried under piles of... less masterful work. I found a fantastic multi-chapter where Oliver is trapped in the League of Assassins and Nyssa al Ghul is the central POV character, and it's only got like twelve reviews. You have to dig, but the gems are there. My current bookmark is a crossover with 'The Blacklist' on AO3, where Oliver Queen and Raymond Reddington have to negotiate a truce between their... respective circles of influence. It shouldn't work, but the author nails the voices. That's the kind of thing I'm always hunting for—the storyline that makes you see the characters in a whole new light.

Been crawling around looking for that exact combo lately! My obsession started after reading a surprisingly tender Batman-meets-Cyborg fic on Archive of Our Own, which then sent me down a rabbit hole. The thing is, you'll rarely find a tag that perfectly says 'cyborg x robin superhero crossover'—you gotta get creative. On AO3, I start by filtering for fandom tags like 'Teen Titans (Comics)', 'DCU (Comics)', and maybe even 'Marvel' if I'm in a crossover mood. Then I'll add relationship tags for 'Victor Stone/Cyborg & Damian Wayne' or 'Victor Stone & Dick Grayson' and sort by kudos. A lot of times, the best crossovers are hiding in plain sight as team-ups that slowly build the dynamic. Don't sleep on fanfiction.net either, even if it's older. The search function is clunky, but browsing the 'Teen Titans' and 'Batman' categories can unearth some gems from like 2012 where authors mashed up heroes more freely. Just be ready for some, uh, vintage early-2010s prose. Sometimes those old fics have the most bonkers, enthusiastic crossover plots where Cyborg ends up in Gotham or Robin gets zapped into a totally different universe. Honestly, Tumblr is a wildcard but useful. If you find a writer who draws or gifsets of Cyborg and any Robin interacting, check their blog. They often link to their own fics or reblog others'. It's a more scattershot approach, but I've found some fantastic, niche one-shots that way that never got big on the major archives.

Crossover fics with Red Hood are honestly a bit scattered, depending on which superhero you want to pair him with. I mostly see him with the Batfam, obviously, but if you're looking for Marvel crossovers, try searching for 'Red Hood & Wolverine' or 'Red Hood & Deadpool' on Archive of Our Own—the tags are pretty robust there. Tumblr sometimes has hidden threads where writers link to their Google Docs, which can be hit or miss but occasionally turns up something brilliant. There's also a specific trope where he gets dumped into the Young Justice cartoon universe, which is surprisingly popular. I'm less certain about DC crossovers with smaller indie heroes, but checking the main fanfiction.net categories for 'Red Hood' and then filtering by 'Crossover' will give you a huge, if unorganized, list. Don't forget to sort by kudos or favorites; quality varies wildly. Honestly, my luck has been better with dedicated Discord servers for specific pairings. Someone will just drop a link to a 200k word epic where Jason somehow ends up mentoring the Runaways, and you lose your entire weekend.

If you're hunting for that specific Olicity arrowverse content, AO3 is basically your only realistic option these days. The tagging system there is so precise you can filter for 'Oliver Queen/Felicity Smoak,' then add things like 'Post-Season 3' or 'Canon Divergence' to get exactly the right flavor. I tend to sort by kudos or bookmarks to find the community-vetted highlights. Finding the 'best' is subjective, obviously. Some of the most kudo'd works are epic slow-burns that rebuild the whole show, while others are these perfect little missing moment one-shots that slot right into an episode. My personal favorites are the ones that explore Felicity's tech skills as more than a plot device, giving her real agency. The '5 times' and '10 times' trope fics are also a solid entry point if you want quick reads that nail their dynamic. Honestly, the quality on AO3 can be shockingly high—better prose than some published novels I've read. But you have to wade through a lot to find it. I'd avoid the 'Complete Works' filter initially and look at works-in-progress with consistent update schedules; sometimes the hottest ongoing fics haven't accumulated the stats yet but are absolutely brilliant. FanFiction.net still has an archive, but it's a ghost town for new content and the search is terrible. Tumblr has snippets and headcanons, but for full, polished narratives, AO3 is the hub. I'd start with authors like 'somewheressword' or 'tdgal1'—their back catalogs are deep and they really understand both characters.

Arrow? Like Green Arrow? Honestly, I'd skip the show-based fics entirely if you're just starting. Most of it is heavy Felicity or Olicity stuff from years ago, and the quality is super inconsistent. I'd point anyone to the comics-inspired fics on AO3. Look for works tagged with 'Oliver Queen/Black Canary (DCU)'—that's the classic Dinah Lance pairing from the comics, not the TV show's version. There's a fantastic, old-school author named 'sapphicschina' who writes these tight, character-driven one-shots that feel like lost issues. Another great one is 'kingmakers' which is a sprawling, modern-day mob AU that somehow gets Oliver's voice perfectly—that charming, haunted bravado. You can also filter for 'Oliver Queen & Roy Harper' if you want some classic mentor-protege found family stuff, less romance-focused. Just avoid the 'Arrowverse' crossover tag at first; it gets overwhelmingly big.

Finding crossover stories with solid original twists for the Turtles is actually a bit of a deep dive. The standard fare on AO3 or FF.net is packed with 'Turtle Power meets Avengers' stuff, which is fun but rarely does anything new. What worked for me was getting a lot more specific with the tags. I skip the big crossover fandom tags and search for 'alternate universe' plus 'canon divergence' attached to 'TMNT'. That tends to filter out the straightforward team-ups. The real gold is in stories that drop the Turtles into a world with a completely different rule set and force them to adapt. I found a fantastic one where the 2012 series turtles ended up in the post-apocalyptic world of 'The Last of Us', with Donnie trying to understand Cordyceps while Leo and Raph argued over the morality of survival in that setting. The twist was that the fungus didn't affect them because they're mutants, which created this fascinating dynamic where they were both feared and needed. Smaller, more character-focused fanfic communities on Discord servers dedicated to specific iterations of the Turtles, like the IDW comics or the 2003 cartoon, often host writers who are deep into lore and more likely to experiment with plot. That's where I stumbled on a 'TMNT/Persona 5' crossover that was less about the Phantom Thieves and more about the Turtles navigating the Metaverse as a reflection of their own hidden struggles, which was a twist I'd never seen before.

AO3's the most reliable hub for that specific mix, but navigating it takes some finesse. You can't just filter for 'Marvel's Agents of S.H.I.E.L.D.' and 'crossover' and expect magic. The trick is searching by character. Plug in 'Phil Coulson' or 'Daisy Johnson' as a character tag, then use the 'Crossovers' filter. That's where you'll find them woven into 'The Avengers', obviously, but also the good unexpected stuff like 'Daredevil' or 'The Flash'. The tag 'Post-Season 4' is a goldmine for dimension-hopping plots that naturally lead to crossovers. Don't sleep on niche forums either. There's a dedicated corner on FanFiction.net under the 'Marvel' TV section that's surprisingly active with older, completed crossover epics. The search function is clunky, so I lurk in community threads where people rec fics. Someone there once linked this wild, completed story where the team gets stranded in the 'Supernatural' universe and has to deal with angels and demons instead of Hydra. The characterization was shaky in parts, but the premise alone kept me reading for twenty chapters. Honestly, your best finds might come from Tumblr. Bloggers who are deep into both 'AoS' and, say, 'Young Justice' will often have curated tag pages or recc lists. It's more scattergun than AO3, but you stumble on art and snippets that lead to WIPs not fully tagged yet. The algorithm's useless; it's about following the right people. I found a brilliant FitzSimmons-in-Gotham fic that way that hadn't even hit the front page of AO3 yet.
