Which Anime Has An Undertale Crossover Episode?

If you’re asking about studio-made crossovers, nada. But 'Undertale’s' DNA is all over anime aesthetics. Think 'Madoka Magica’s' subverted expectations or 'One Piece’s' found family themes. Even 'My Hero Academia’s' Sans-esque meme face owes something to Undertale’s cultural seepage. For actual crossovers, you’d need to dive into fan comics—like that 'Undertale' x 'Demon Slayer' AU where Flowey is a demon. Wild stuff!

Zero official episodes, but the fandom’s made up for it. Ever stumble upon 'Undertale' x 'Death Note' theories? Sans as a Shinigami fits weirdly well. Or the 'Undertale' characters redesigned in 'Dragon Ball’s' art style? It’s not canon, but it’s the next best thing. Sometimes, fan love outshines the real deal.

You know, I've been digging through anime and game crossovers for ages, and this one's a tricky find! While there isn't an official anime episode that directly crosses over with 'Undertale,' the game's influence pops up in fan works and references. For instance, 'Hetalia: Axis Powers' had a meme-worthy moment where fans edited Sans into a scene, but that's purely fan-driven. The closest you might get is 'Deltarune''s Toby Fox collaborating with 'Anime Expo' for a short musical animation—but it's not a full episode. Honestly, 'Undertale''s charm is so unique that it thrives in its own universe, though I'd kill to see an anime studio take a crack at it!

That said, indie crossovers are everywhere if you look hard enough. Some doujin circles have mashed up 'Undertale' with shows like 'Nichijou' or 'JoJo’s Bizarre Adventure' in comics or AMVs. If you're craving that vibe, hunting down fan animations on YouTube or Nico Nico might scratch the itch. 'Undertale' fans are creative beasts—they’ve built entire AUs that feel like alternate anime arcs.

I wish there was a straight answer, but nope—no anime episode officially crosses over with 'Undertale.' The game’s too indie for that. But! Toby Fox’s music made it into 'Smash Bros.,' and 'Deltarune Chapter 2’s' release had anime-style promo art. Fanworks are where it’s at: check out 'Undertale' x 'Ghibli' AU art or the 'Papyrus in One Piece' edits. The community’s creativity is the real crossover.
