Where Can I Find Mordecai X Margaret Crossover Fanfiction With Unique Plots?

Been trawling the 'Regular Show' tags on AO3 for ages, and the Mordecai x Margaret fics that actually stick with me are the ones that feel like they could be lost episodes—not just romantic fluff. 'Analog Signals' by cartunes is my absolute top rec. It’s a slow-burn post-graduation AU where they reunite at a failing record store, and the author nails the awkward, unresolved tension that the show left us with. The dialogue has that specific blend of melancholy and dumb humor the show did so well. What sets it apart is how it treats Mordecai's self-sabotage not as a joke, but as a genuine character flaw he has to work through, while Margaret's ambition isn't softened. They feel like real adults, not just cartoon characters. The supporting cast pops in perfectly, too—Rigby’s cameo had me cackling. It’s less about grand declarations and more about two people figuring out if their wavelengths still match after everything. The ending is bittersweet but hopeful in a way that just fits.

Man, that's a deep cut! I used to be so into 'Regular Show' fanfic back in the day. Margaret and Mordecai's whole 'will they, won't they' was practically engineered for fanfiction. I remember a really memorable one called 'Coffee Shop AU' where they're both baristas after graduating from college—it flipped the dynamic completely, making Margaret the slightly jaded manager and Mordecai the new, overly earnest hire. The author nailed their awkward, hyper-verbal banter. Another classic in my book is 'The One Where Benson Actually Helps,' which is exactly what it sounds like. It's a fix-it fic set after the Season 5 finale, where Benson sits them both down for a brutally honest talk. It's less about romance and more about the painful clarity of adulthood, which hit harder than I expected. The writing felt true to the show's bittersweet vibes. For a complete shift in tone, there was a wild crossover with 'Gravity Falls' where they both end up in the Mystery Shack. Sounds ridiculous, but it somehow worked because both shows share that weird, surreal heart. Mordecai's neuroses played off Dipper's perfectly.

Searching for that specific crossover can feel like looking for a needle in a haystack, but a haystack worth searching, you know? I’ve never actually seen a full-blown Randy x Theresa story, probably because 'Randy' is a bit ambiguous—are we talking 'Trailer Park Boys' Randy, or maybe Randy from 'South Park'? I’m assuming Theresa from something like 'Maze Runner'? The mismatch in fandoms itself is a huge barrier. What I’ve had some success with is using the filter systems on Archive of Our Own. You’d have to tag both source canons separately and then just... scroll forever, hoping someone had the same bizarrely wonderful idea. I once spent a whole afternoon looking for a crossover between 'The Expanse' and a cooking show, so I feel the pain. For truly unique plots, you might have more luck commissioning a writer you admire on a site like Fiverr or through a fandom Discord, honestly. That pairing is niche enough that waiting for it to appear organically could take years.

The relationship's evolution in fanfiction hinges on a tension between the original text's restraint and the fandom's desire to fill that space with something messier and more explicit. In 'Regular Show', their dynamic is defined by missed connections, workplace propriety, and unresolved subtext—which is catnip for writers. I've seen it go in two major directions. One path leans into a realistic, slow-burn office romance, dealing with the logistics of dating your boss's daughter while Muscle Man makes inappropriate jokes in the background. It's full of awkward coffee breaks and stolen glances that feel true to the show's vibe. Another, more popular route is pure, high-stakes fantasy. These stories often pull them out of the park entirely, throwing them into supernatural AUs or intense crossovers where the usual social constraints don't apply. I remember one 'Bioshock' fusion where Mordecai was a Big Daddy and Margaret a Splicer—it was bizarrely effective at externalizing their communication issues. The evolution there is less about getting together and more about surviving a shared trauma, which forces a kind of intimacy the show could never show. Whether it's angst or fluff, the core drive is always about granting them the agency their cartoon selves lacked.

It's funny, I feel like I've read fifty different versions of their dynamic. The most common thread has to be 'what if they were both a little less repressed?' Canon gave us all that simmering tension in the office, but so many writers just can't resist pulling the trigger. You'll see a lot of stories that start from a small canon divergence—maybe Margaret stays late to finish a report, or Mordecai finally snaps and asks her out for a coffee that isn't just about work. The early stages are almost always awkward, with both of them tripping over their own professionalism. It's a slow dismantling of their workplace personas. Where it gets really popular, though, is in the 'established relationship' fics that skip right to the domesticity. People love imagining them navigating a shared apartment, with Mordecai being impossibly neat and Margaret secretly leaving her mugs everywhere. The conflict shifts from 'will they or won't they' to 'how do these two very particular people build a life together?' The appeal is less about the chase and more about the quiet compatibility underneath all the stiffness. A whole other branch leans into the angst potential. What if someone from Mordecai's past showed up? What if Margaret got a better job offer elsewhere? Those fics explore the inherent instability in their bond, the fear that the other person might just be too… much. It's less fluffy, but it feels grounded in the characters' core anxieties.

That pairing definitely seems to have found its home on Archive of Our Own. The tagging system makes it so easy to find specific ships, and there's a huge volume of 'Regular Show' fic there. I've spent more time than I care to admit scrolling through the Mordo/Margaret tag. Tumblr used to be a bigger hub for it, but these days it feels like most of the multi-chapter stuff and detailed one-shots migrate over to AO3 for permanence. You'll still find snippets, headcanons, and shorter drabbles on Tumblr, especially in the 'regularshow' tag, but for the actual stories, AO3 is the main archive. I haven't seen a concentrated amount for them on FanFiction.net in years; the 'Cartoons' section there feels pretty quiet for this fandom now.

honestly, it's a wasteland of repetition. You get the same five 'Ekko saves Jinx from the undercity' or 'time-travel fix-it' plots on repeat. My breakthrough came when I stopped using the standard tag filters. On Ao3, I sorted by 'Kudos' but then went to page 15 or 20—that's where the buried, weird stuff lives. I found one where Jinx was a ghost only Ekko could see, haunting the Firelights' base, and another that was a cosmic horror AU where the Hextech crystal was an eldritch entity warping reality around them. It felt less like a romance and more like a psychological thriller. For truly unique plots, you have to get creative with the crossovers. Instead of just searching 'Arcane', look for fandoms with similar tonal DNA. I had luck searching 'Arcane' and 'Dishonored' together—someone wrote a Corvo-attuned Jinx and an Outsider-touched Ekko in a steampunk Dunwall, and the dynamic was all about parallel paths of power and madness. The real gold is in the comment sections of those rare fics, too. Authors sometimes drop recommendations for similar vibe stories, which is how I found a 'Control' crossover where they were both Bureau agents dealing with altered items. The platform hopping is exhausting but worth it.

One theme I've seen a lot is Margaret's lingering trauma from her divorce and her struggle with trust. Writers love putting her in situations where she has to rely on Mordecai, and her fear of being hurt again clashes with his awkward but genuine attempts to be dependable. It's not just about 'will they or won't they'; it's about whether she can let herself be vulnerable with someone who fumbles so much. Another angle is focusing on Mordecai's intense, almost paralyzing anxiety about not being good enough for her—not smart enough, smooth enough, or successful enough compared to her ex. Stories where he overhears someone implying Margaret settled for him, or where he botches a planned romantic gesture, can spiral into some real painful introspection. It works because his insecurity is so rooted in his character. I've also read a few where the angst comes from external judgment, like Rigby or Benson making an offhand comment that Mordecai misinterprets as serious criticism of the relationship. The conflict feels very true to the show's dynamic, where humor masks real feelings.

Sometimes I wonder if everyone else is reading the same stories I am. Most recs you get for Mordecai and Margaret fixate on post-series 'will they won't they' fluff, which is fine, but misses their whole dynamic. They're both emotionally constipated control freaks, one a disillusioned ex-spy, the other a hyper-competent widow who buried her own needs. The real meat isn't in cute dates; it's in the brutal, quiet work of two people who have to unlearn every defense mechanism to be vulnerable. A story that absolutely gutted me is 'Consequence of Habit' on AO3. It's not tagged as heavy angst, but it should be. It deals with Margaret inheriting a family estate full of her late husband's things and Mordecai being hired to appraise the art. The conflict isn't external. It's in the excruciatingly polite conversations over tea where Margaret can't admit she needs help packing away a life, and Mordecai can't admit he's jealous of a ghost. The author uses physical objects—a chipped vase, a ledger book, the way a painting is hung—to show the emotional stalemate. It's painfully slow, and the climax isn't a confession, it's Margaret silently crying in a closet full of old coats while Mordecai waits outside the door, knowing he can't fix it, only witness it. That story understood that for these two, love looks less like grand romance and more like showing up to hold the baggage, even when you're terrible at it. I come back to it when other fics feel too shiny.

I completely get the hunt for those specific crossover fics pairing Mabel Pines with Wendy Corduroy from 'Gravity Falls'—it's a niche but fun dynamic to explore. You'll have the best luck on dedicated fanfiction archives. Archive of Our Own is my top recommendation; its tagging system is incredibly detailed. Searching for the relationship tag 'Mabel Pines/Wendy Corduroy' and then filtering by the 'Crossover' category or adding additional fandom tags usually surfaces some interesting blends. Crossposting happens often, so checking both AO3 and FanFiction.net is a solid move, though AO3's filters make the process smoother. To spark some inspiration, think about the worlds that would mesh well with their vibes. I've seen crossovers where they get thrown into the summer-camp chaos of 'Camp Camp', or where the weirdness of Gravity Falls intersects with the mysteries of 'Steven Universe' or 'Star vs. The Forces of Evil'. These settings let Mabel's boundless optimism and Wendy's laid-back cool play off new characters and magical rules. The 'Supernatural' tag can also lead you to fics where they team up for monster-hunting adventures, which creates a great contrast between Wendy's practical survival skills and Mabel's glitter-fueled problem-solving. Don't overlook Tumblr or Twitter either, sometimes writers will share snippets or concepts there with specific tags like '#mabwendy' or '#gravity falls fanfic'. Following artists who draw the pair can also lead you to writers they collaborate with. Finding these stories often involves a bit of digging, but stumbling upon a fic where Mabel ropes Wendy into a quest in a totally different universe makes the search totally worthwhile. I love it when a story manages to keep Wendy's dry humor intact while Mabel makes friends with, say, aliens from another franchise.
