Watching the fandom evolve over the seasons was a trip, and the tropes that stuck around tell you everything about what we were collectively craving. The big one for me is 'Paladins as a Family,' but specifically the messy, found-family-during-a-crisis version, not the perfect one. You see a ton of fics where Lance is the emotional glue, Hunk is the heart, Pidge is the chaotic tech genius, and they're all trying to keep Keith from self-destructing while Shiro plays space dad. It’s the hurt/comfort that really sells it—someone getting captured, injured, or having a breakdown, and the others scrambling to put them back together.
Another massive category is the AUs that transplant the team into completely different settings. Coffee shop AUs are perennial, but I’ve seen some brilliant ones set in fantasy realms or even as a band on tour. The core dynamic remains, so you get to see Keith’s brooding intensity as a guitarist and Lance’s showmanship as a frontman. It’s a testament to how strong the character archetypes are that they work anywhere.
And, okay, I have to mention the shipping. Klance and Sheith dominated the discourse, obviously, but what I find more interesting now are the deep dives into less-central pairs. Fics exploring the quiet understanding between Shiro and Curtis post-canon, or the hilarious rivalry-turned-friendship between Lance and Keith that doesn’t necessarily turn romantic. The tropes around them—rivals to lovers, enemies to allies, established relationship fluff—they’re tools to explore different facets of the characters we already know, which is really the whole point of the exercise for a lot of readers.
