Mettaton X Papyrus Novels & Stories

People get way too hung up on reading lists for this ship. Honestly, most of the big 'UnderSwap' or 'Undertale AU' fics featuring MTT/Pap stand on their own—trying to follow some fandom-mandated sequence just bogs you down. I jumped into a random 50k-word slow burn where Mettaton was a retired star running a cafe and Papyrus was his baffled, enthusiastic baker. Didn't need any preamble.

Your best shot is to hit the Mettaton/Papyrus tag on Archive of Our Own and sort by kudos or bookmarks. Filter out the crossovers and maybe exclude 'UnderFell' if that vibe isn't for you. The comments on the top two or three fics are usually where readers drop their 'if you liked this, read this next' gems. That's how I found the one where Papyrus tries to teach Mettaton how to cook spaghetti without burning down the studio.

Mettaton x Papyrus always felt like a niche-within-a-niche to me, but its staying power is real. People dig the aesthetic clash—glamour robot meets boneheaded sweetheart—but I think the real glue is the character voids they fill for each other. Mettaton craves an audience that genuinely adores him, not just his persona, and Papyrus is literally incapable of being anything but sincere. He'd love MTT's shows unironically. That dynamic lets writers explore performativity vs. authenticity without getting too heavy. It's also a sandbox for opposites-attract tropes that don't rely on traditional romance beats; you can write anything from domestic fluff where Papyrus tries to cook for a robot to high-stakes drama about souls and bodies.

A lot of its popularity seems to stem from the fandom's collective headcanon space, too. Since their in-game interactions are minimal, it's a total blank slate. Writers get to invent how they'd even meet post-pacifist run. Does Papyrus just show up at MTT's studio with a friendship form? Does Mettaton find him charmingly bizarre? That freedom is a huge draw. Plus, it attracts artists—the visual contrast is super fun to draw, which feeds back into the fic community. You see a cool comic of Mettaton trying to teach Papyrus to dance, and suddenly you're down a tag rabbit hole.

The whole Mettaton x Papyrus thing initially seemed weird to me, mostly because Mettaton spends most of the game actively trying to kill you, and Papyrus is... well, Papyrus. He's innocent, excitable, and genuinely wants to be friends. But I stumbled across this one fic called 'Underestimated Frequency' that kind of sold me on the potential. The author leaned into Papyrus's hidden depths—his loneliness, his desire for validation, his surprisingly sharp emotional intelligence when it comes to Undyne and Sans.

They wrote Mettaton post-pacifist route, grappling with his newfound freedom and the emptiness after achieving his dream of stardom. Papyrus becomes this grounding force, someone who sees the person behind the brand, and Mettaton in turn pushes Papyrus to see his own worth beyond just 'being nice.' It's less about romance right away and more about two characters who don't quite fit the molds their world expects, finding an unexpected connection. The dynamic isn't about smoothing over their differences, but letting those contrasts create friction and then understanding.

What makes it work is that it doesn't soften Papyrus's naivete or Mettaton's theatrical vanity; instead it lets those traits bounce off each other in ways that are sometimes funny, sometimes painfully awkward, and occasionally tender. It's a ship built on mutual fascination with the other's opposite energy.
