What Common Themes Appear In Ava And Alex Fanfiction Relationship Arcs?

Honestly, the Ava/Alex dynamic seems to shift completely depending on which fandom you're coming from. If you're talking about something like 'The Umbrella Academy' where those names could fit a few characters, it's usually the intense, rivalry-to-reluctant-partners arc that dominates. The Five and Diego stuff gets rewritten with those names constantly. But I've spent more time in the 'Detroit: Become Human' sphere, and there, Ava and Alex are almost always androids—exploring consciousness, the right to exist, that kind of thing. The most popular threads I see are the 'human adopts/android protects' trope or the 'two androids discovering emotion together' slow burn. The latter gets really philosophical, sometimes losing the plot for pages of internal monologue about what it means to feel. It can be a bit much, but when it's grounded in a good heist or survival plot, it shines. What surprises me is how rarely I see them cast as outright villains. Even in darker AUs, they're usually tragic figures or anti-heroes, not pure evil. Maybe the names just sound too approachable. I'd love to find a truly terrifying Ava or Alex story, but the tags never really go there.

The 'enemies with benefits' setup is basically a pressure cooker where the characters' relationship has to explode eventually. You've got the surface-level animosity, but it's built on a foundation of mutual respect or obsession that neither wants to admit to. The forced proximity trope is almost mandatory—they're stuck together as partners on a high-stakes project, or they're rival heirs forced to share an office. The 'one bed' scenario in a hotel during a business trip is a classic catalyst. What keeps me hooked is the internal conflict. The tropes around 'faking it till you make it' and secret pining work overtime here. They'll have this unspoken rule to never kiss on the mouth, or to never stay the night, and watching those rules shatter one by one is the whole point. The power dynamics are constantly in flux, which is way more interesting than a straightforward office romance. I think the most effective versions use the 'benefits' as a form of reconnaissance. They're trying to find each other's weakness, to get a tactical upper hand, but end up discovering vulnerabilities they never anticipated. The betrayal trope looms large, because you're just waiting for the moment one of them uses a pillow-talk secret as ammunition. The real emotional payoff comes not when they stop being enemies, but when they choose to become allies, protecting each other's flank against a common external threat.

When I think about Ava and Alex fics, the emotional tension always seems to hinge on forced proximity—like they’re stuck sharing an apartment after a bad breakup, or stuck on a road trip. That physical closeness makes every glance or accidental touch feel loaded. I’ve read a few where Alex is secretly in love with Ava while she’s dating his brother, and the tension isn’t in big declarations, it’s in him fixing her favorite coffee exactly right and her noticing but not saying anything. The best ones make you feel that ache of something being so close but completely out of reach. Sometimes I think writers rely too much on miscommunication tropes for them, though. An entire 50k-word story where the main conflict is Ava overhearing half a sentence and storming off. It can work, but after a while it just makes me want to shake the characters. I prefer when the tension comes from internal conflicts they can’t articulate—Alex struggling with guilt over a past betrayal, Ava battling her own pride. That feels more real than just not talking. The really memorable Ava/Alex dynamic I read recently was a post-apocalyptic AU where they were the last two people in a city, and the tension was this quiet, desperate need for human connection warring with the fear of losing the only person left. Every conversation was about survival, but every subtext was about loneliness. That kind of setting strips everything back to the emotional core, and you get to see what’s really between them when the world isn’t watching.

One thing I’ve noticed about Ava/Alex fic is how often writers fill in the gaps the original material left blank. On screen, they’re buddies, but in fanfic, you get to see the private moments—staying up too late working a case, the inside jokes that no one else gets, that sort of quiet understanding that builds over years. It’s less about romance for me and more about stretching that platonic bond until it’s practically glowing with shared history. A lot of the best fics I’ve read don’t even have them getting together. Instead, they’ll be stuck in a safe house for a week, or one of them gets injured, and you see all the care and frustration that comes with really knowing someone. It’s a masterclass in showing, not telling, a deep friendship. The tension comes from how well they know each other’s weak spots, not from will-they-won’t-they.

I’ve come across some really touching 'Supergirl' fanfics that dive deep into Alex and Kelly’s relationship, focusing on healing and support. One story had Kelly helping Alex navigate her PTSD after losing her father, blending tender moments with raw vulnerability. The fic explored how Kelly’s background as a therapist gave her the tools to guide Alex through her grief, but it also showed Alex’s strength in leaning on Kelly without losing her independence. Another fic centered on their shared experiences as women in high-stakes careers, balancing their personal struggles with their roles as protectors. The way these stories highlight their mutual respect and emotional intimacy makes them stand out. I especially loved how one writer portrayed their quiet evenings together, where they’d talk about their day or just sit in comfortable silence, showing that healing doesn’t always need grand gestures.

For the Ava and Alex pairing, the landscape's always shifting, but a few stories have stuck with me. 'Static Interference' over on AO3 does this incredible thing where Ava is a radio operator in a remote Alaskan outpost and Alex is the pilot who keeps her supplied. It's a slow burn, but the tension builds through these incredibly detailed transmissions. The author nails the isolation and the growing dependence. Another one, 'Catalyst Protocol', takes a sci-fi angle—they're rival scientists on a Mars mission. The conflict feels real, not just manufactured drama. Honestly, I keep a tab open for that one to check for updates. I'd also recommend sorting by bookmarks on AO3 and filtering for completed works. There's a hidden gem, 'The Things We Leave Unsaid', that's technically a coffee shop AU but it's less about coffee and more about Alex dealing with anxiety and Ava being the relentlessly patient regular who quietly rearranges the sugar packets to spell out messages. It's quieter than most, but the emotional payoff wrecked me. The fandom can get obsessed with high-stakes AUs, but sometimes the domestic ones hit harder. I'm still thinking about the last chapter.

I was searching for this exact thing a while back because I read everything in the 'Ava & Alex' tag on Ao3 and wanted more. Honestly, your best bet is to go straight to Archive of Our Own and use their filtering system. Tag 'Ava & Alex' (or whatever the specific pairing tag is, sometimes it's character/ship names) and then add the 'Crossover' tag. You can also filter by fandom and just browse the crossover section of whatever other universe you're interested in, looking for 'Ava & Alex' characters tagged. I've found some really weird but fun ones crossing over with 'The Magnus Archives' and even 'The Locked Tomb' series, which shouldn't work but somehow does. Some writers will tag the relationship but not necessarily list it as a primary fandom if the crossover element is light, so you gotta dig a bit. I remember one where Ava and Alex were mysteriously transported to the world of 'The Witcher' and had to navigate that. It was more of a fusion than a strict crossover, but the character voices were spot-on. Don't overlook tumblr blogs dedicated to the pairing either; sometimes they recc lesser-known crossovers from smaller fic archives or even google docs links. Word of warning though: the quality varies wildly. A lot of crossover fics lean heavily on one fandom's rules and kind of force the other characters in, so Ava and Alex can feel out of place. I usually check the comments and kudos count to see if it's worth my time. Happy hunting! It's a bit of a scavenger hunt but finding a good one is so satisfying.

The fanfiction subreddit for whatever fandom Ava and Alex are from is a surprisingly good crossover hub. I'm active on the one for 'The Brightest Star' and people are always tossing out 'what if' scenarios with characters from other media. You'll find threads dedicated specifically to crossover pairings, often with links to stories on AO3. The search function on Reddit isn't great, so I usually just post a question like 'Looking for Ava/Alex crossovers with 'Cyber Nexus'—anyone know some?' and within an hour someone will drop a few links. Also, don't sleep on Tumblr tags. It's chaotic, but if you search the ship tag combined with 'crossover' or 'fusion', you'll stumble upon reblogs of fic snippets and full story links. The key there is following the right blogs; some creators focus almost exclusively on crossover AUs. I found this wild Ava/Alex meets 'Shadowrun' fusion that way, and it's been my obsession for a week.

One thing I’ve noticed in a ton of 'Ben 10' fanfic is how they handle Ben and Gwen being cousins. So many authors get stuck on that initial 'ick' factor and just circle it forever, like the whole story is just them angsting about whether it’s morally wrong. I mean, I get it, it's a huge elephant in the room, but after a while it just gets repetitive. The better stories, in my opinion, move past that pretty quick and dig into what would actually cause friction between them as a couple. For example, Gwen’s whole personality is built on being super organized, academically driven, and a little bit of a control freak. Ben is the opposite—impulsive, hero-first-think-later, and kind of a slob. So a conflict I see done well is when Gwen gets frustrated because Ben promises to study for a test or help with a project, but then he runs off to fight a Forever Knight or something. It’s not just about the missed date; it’s about her feeling like she’s never his priority over being a hero. That’s a real, grounded issue. Another good one is the power imbalance. Ben has the Omnitrix, he’s literally the most powerful being on Earth sometimes. Gwen has her magic, which is powerful too, but it’s studied and earned. I’ve read fics where she feels overshadowed, or where Ben assumes he has to protect her and she resents that, thinking he doesn’t respect her capabilities. That dynamic can lead to some heated arguments about trust and equality, which feels way more substantial than just ‘oh no we’re related’. Sometimes the conflict is external, like how Grandpa Max or their parents would react. But honestly, I skip those fics most of the time because they tend to be super melodramatic. I prefer the internal, character-driven stuff. Like, Ben’s fear of losing control as an alien and hurting her accidentally, or Gwen’s anxiety about their relationship changing the team dynamic and ruining their ability to work together. That stuff keeps me reading.

Oh, this depends so much on what you're looking for. The big umbrella sites like Archive of Our Own and FanFiction.net obviously have the sheer volume, especially for popular pairings. But 'best' is subjective—are you after fluffy one-shots or epic novel-length AUs? AO3's tagging system is a lifesaver for narrowing down exactly the kind of Ava/Alex dynamic you want, whether it's enemies-to-lovers or established relationship fluff. I sometimes find the real gems on smaller, fandom-specific forums or even Tumblr threads, though. Those writers often have a more focused, intense take on the characters because they're writing for a tight-knit community. The downside is discovery can be a pain. Honestly, don't sleep on Wattpad either, even if the search function is a nightmare. Some of the most surprisingly poignant Ava/Alex stories I've stumbled on were there, buried under a mountain of less-polished work. It feels more like sifting through a friend's personal rec list than a formal archive.
