Honestly, my go-to for Mettaton x reader fics is a mix of AO3 and Tumblr. AO3’s filters let you dive straight into the high-rated stuff, and I’ve bookmarked a few authors who consistently deliver that perfect blend of showmanship and vulnerability Mettaton deserves. Tumblr’s more chaotic, but that’s where you find the experimental pieces—think alternate AUs or fourth-wall-breaking romps. Once, I found a noir-style fic there with Mettaton as a detective, and it was bizarrely brilliant. Don’t sleep on FF.net either; it’s older, but some classics lurk in the archives.
Mettaton x reader fanfiction is one of those niches where passion really shines through, and it’s always a delight to see how creative the fandom gets with this flamboyant character. If you’re hunting for the best stories, I’d start with Archive of Our Own (AO3). The tagging system there is a godsend—you can filter for Mettaton-centric fics, sort by kudos or comments, and even exclude tropes you’re not into. I’ve stumbled upon some absolute gems there, like 'Neon Spectacle,' where the author nails Mettaton’s dramatic flair while weaving in a surprisingly tender romance. Tumblr also has a thriving community; some writers post shorter drabbles or headcanons that are perfect if you want something quick but impactful.
Don’t overlook smaller forums or Discords either. I once found a WIP (work in progress) on a dedicated 'Undertale' fan forum that had the most in-character Mettaton dialogue I’d ever read—sadly, it vanished before completion, but it taught me to cherish hidden corners of the internet. Wattpad can be hit or miss, but sorting by engagement helps. A pro tip: check out authors who’ve written for other charisma-heavy characters (like Papyrus or Hades from 'Hades')—they often bring that same energy to Mettaton. And if you’re into audiobook-style experiences, some creators on YouTube do dramatic readings of popular fics, which adds a whole new layer of fun. Just losing myself in those over-the-top performances feels like attending one of Mettaton’s shows!

"You have no idea, do you, Melanie?" Her stepuncle murmured, his thumb sliding over her bottom lip, pulling it down slightly.
"Your stepdad’s been fantasizing about you for so fucking long, it’s practically making him sick. He’s been dying to ruin you."
Her heart did a violent flip in her chest.
She should have been completely mortified by the raw confession. She should have been disgusted that her stepdad was looking at her like a piece of meat, or that her stepuncle was casually talking about it in their family living room.
But instead, a wave of liquid heat flooded her lower belly. Her traitorous, filthy cunt began pulsing with a wild, animalistic intensity, soaking through her thong in a desperate gush. She was so aroused it made her dizzy.

“You are mine.” Jerald possessed, trailing wet kisses down Jasmine's body while she let out uneven breaths, her body tingling as tiny ripples sneered through her.
Jerald's right hand gripped her heavy tits and he fondled hard, kissing her navel, obsession burning through his every act.
“You are mine. Jasmine… your body..” He paused and kissed her navel.
“Your heart and your soul... Everything belongs to me.” His voice was laced with domination as he moved his head downward, trailing wet kisses down her body till he parted her legs with his head, burying his face between her beautiful thighs.
*
This high and Mighty never took NO for an answer. He is Jerald De Luca. Either business or Women, he would surely always have his slightly illegal way.
When Jasmine crawled into his bed with the intention of saving up for some medical bills, she thought everything would last for a month like the contract spelled out. Everyone has been to his bed, but none has ever won his heart like she did. She was the opposite of him, calm, yet fierce and unyielding. She didn't bend to his will like the air and every other woman did and most differently, her eyes held the light that was missing in this world.
This mare lust grew into a love that pioneered an unshakable obsession. The desire to protect her was like second nature, clogging his every breath like a whispered secret. But when life challenges come crashing in, threatening to rip their relationship apart, Jerald is faced with the harsh reality of life. This angel was not so innocent as he forsee and all along he had been the enemy that he had sworn to protect her away from.
Mettaton's flirting style in x reader stories is this dazzling mix of theatrical charm and calculated seduction that just works. He’s all about the performance—dramatic compliments, lingering touches, and that signature confidence that borders on narcissism (but in the best way). Writers often play up his showmanship, having him drop lines like 'Darling, you’re stealing the spotlight from me—and I allow it,' or teasing with exaggerated winks and poses. There’s usually a layer of playful competition too, like challenging the reader to a dance-off or karaoke duel, where the stakes are 'loser kisses the winner.' It’s cheesy, over-the-top, and yet weirdly endearing because it’s so him.
What I love is how fics balance his ego with vulnerability. Behind the glitter and one-liners, there’s often a moment where he lets the act slip—maybe he’s genuinely impressed by the reader’s talent, or he lowers the microphone to whisper something sincere. The contrast between his diva persona and these softer glimpses makes the flirting feel layered. Some stories even lean into his robot side, with flirty glitches or overheating circuits when the reader gets too close. It’s a fun way to blend his character quirks with romance tropes, like enemies-to-lovers or celebrity-crush dynamics.
Mettaton from 'Undertale' has this flamboyant, larger-than-life personality that makes him perfect for reader-insert AUs. One popular idea is the 'Celebrity Romance AU,' where the reader is either a fan or a fellow performer who gets swept up in Mettaton's glamorous world. Imagine backstage rendezvous, secret dates hidden from paparazzi, and the tension between his public persona and private self. Some fics dive into the reader being his assistant, navigating his diva moments while uncovering his softer side. Others go for a 'Human vs. Monster' angle, where the reader is a human who ends up in the Underground and catches his eye—maybe they’re a dancer, a technician, or just someone who isn’t impressed by his theatrics, which of course intrigues him.
Another favorite is the 'Ghostly Connection AU,' playing into Mettaton’s pre-robot history. Here, the reader might be a ghost or spirit who knew him before Alphys transformed him, leading to bittersweet nostalgia or unresolved tension. Some writers explore a 'Bodyguard AU,' where the reader is hired to protect him from overzealous fans or anti-monster extremists, forcing them into close proximity. There’s also the 'Rival Show Host AU,' where the reader hosts a competing TV show, sparking a love-hate dynamic full of on-air banter and behind-the-scenes chemistry. The key in all these is balancing his arrogance with vulnerability—fans love when the reader calls him out, only to discover he’s not as self-assured as he acts.
Mettaton from 'Undertale' has this flamboyant, larger-than-life personality that just begs for dramatic storytelling. His blend of showmanship, confidence, and underlying vulnerability creates a perfect storm for shipping dynamics. Fanworks love pairing him with readers because he’s already coded as a performer—someone who thrives on attention and connection. It’s easy to imagine him sweeping a reader into his world of glitter and spotlights, whether as a romantic lead or a chaotic best friend.
What really seals the deal is his character arc. From a seemingly shallow entertainer to someone with deeper motives, he offers layers to explore. Writers can play with tropes like 'enemies to lovers' or 'celebrity/normal person' while tapping into his canon charm. Plus, his robotic form opens up creative avenues—how does love or friendship work for someone who isn’t entirely human? The fandom’s reinterpretations range from sweet to existential, and that flexibility keeps the ship thriving.
