Which Platforms Host Popular Lucario X Mewtwo Crossover Fanfiction?

Lurking in fanfiction communities for years has shown me that truly niche crossover pairings like Lucario and Mewtwo tend to congregate in very specific corners, because mainstream platforms can sometimes bury them under more common ships. For a crossover this specific, you're generally looking at a couple of key hubs. Archive of Our Own is probably the most reliable centralized source. Its tagging system is a godsend for this. You can filter for the 'Pokémon' fandom, then combine character tags for 'Lucario' and 'Mewtwo,' and further narrow it to the 'Crossover' category or the specific fandom you want them crossed with, like 'Super Smash Bros.' or something entirely unrelated. The depth of tags means stories exploring their dynamic as rivals, allies, or something more speculative are all findable with patience.

Another classic spot is FanFiction.net, especially in its Pokémon section. The sheer volume there means older stories for this pairing might be archived. The search function is less precise, so you’d need to sift through Lucario-centric stories and see if Mewtwo appears as a major character, or vice versa. It often involves more manual digging, but some real foundational fics for unusual pairings can be found in those older archives. Smaller, dedicated Pokémon fanfiction forums or sites like Serebii's forums used to host a lot of that content, though activity has shifted over time.

The nature of the pairing itself shapes where it thrives. Stories that lean heavily into the lore of both characters—exploring aura versus psychic power, their roles as unique creations, or their encounters in games like 'Super Smash Bros.'—might pop up on niche writing communities that focus on philosophical or battle-heavy narratives. Meanwhile, more character-driven or relationship-focused interpretations might flourish on Tumblr or Twitter through threaded stories, though those are harder to archive and search systematically. Your discovery really depends on whether you’re hunting for epic crossover battles or a quieter, more introspective character study. I usually start with AO3's tag filters and work outward from there, and sometimes the trail leads you to an author's personal site or a forgotten forum thread that feels like striking gold.
