Felix X Oswald Novels & Stories

I just revisited a few fics where Oswald's in control and Felix is trying to charm his way out of a situation, and honestly, it flips their canon dynamic on its head in such a satisfying way. Canon Felix always felt like he held all the cards, but when Oswald's the one with leverage—like in those fics where he catches Felix snooping or Felix needs a favor—you see this desperate, performative side of Felix that's way more vulnerable. He's not just a smooth talker; he's scrambling, and Oswald gets to be the sharp observer cutting through the act.

What I really dig is how the best writers use their mutual obsession with wealth and status as a twisted love language. It's never 'I love you'; it's 'I know exactly which antique you'd fake for insurance' or 'I noticed you upgraded your cufflinks.' The power struggle becomes this endless, intimate game where every gift is a threat and every compliment is a dig. That tension is way more electric than any straightforward romance could be.

Finding those fics can be a real adventure! Honestly, I'd head straight to Archive of Our Own and filter by the Felix/Ferdinand von Aegir & Oswald tag. The volume there is just unmatched, and the tagging system lets you zero in on anything specific you're craving, whether it's enemies-to-lovers or post-canon fix-its. Sometimes I get overwhelmed by the sheer number, so I sort by kudos to find the real crowd-pleasers first.

A lot of the really classic, longer works from the fandom's peak activity are still up on FanFiction.net, though the tagging isn't as precise. You have to dig a bit more manually, which has its own charm—I've stumbled on some absolute gems I'd never have found otherwise by just scrolling through the 'Fire Emblem: Three Houses' section. The prose in some of those older ones feels different, more formal maybe, but I've got a real soft spot for them.

Don't sleep on Tumblr either. A lot of writers will post shorter snippets, headcanons, or even link to their AO3 works directly from their blogs. The interaction feels more immediate, and you can sometimes find WIPs or ideas that haven't made it to the big archives yet. I just really love that sense of a living, breathing community sharing little bits of the ship every day.

I spent a weird amount of last year deep in the 'Gotham' tag on AO3, specifically for Felix and Oswald, and the tropes are... distinct. A huge one is the 'villainous power couple' angle, but it’s rarely just about ruling the city. There’s so much focus on Oswald tending to Felix’s injuries after a fight, bandaging his hands while Felix tries to play it off like it’s nothing. It’s this quiet, domestic intimacy layered over their mutual ambition.

Another staple is the 'arranged partnership that becomes real'. A lot of fics start with Oswald hiring Felix purely for his skills, a transaction, but then they get stuck in a safe house together or have to flee the GCPD, and forced proximity does its thing. The tension comes from Felix realizing he’s loyal to Oswald the man, not just the paycheck.

You also see a fair bit of role reversal where Felix is the one with a moral crisis—maybe he has to protect someone innocent and Oswald doesn’t get it—creating a rift that forces them to renegotiate their relationship. It’s less about redemption and more about finding a new equilibrium within their gray-area lives.

My personal favorite is the rare fics that dig into Felix’s past, his time with the circus, and have Oswald be fascinated by that history, seeing the performer’s discipline in his current lethal precision.
