Archive of Our Own is the first place I check. The tagging system is pretty robust, so you can filter for that specific pairing and then sort by kudos or bookmarks. The character tags are usually 'Underfell Sans (Undertale)' and 'Underfell Frisk (Undertale)'.
I will say, the Underfell AU doesn't have as massive a fic output as, say, the main Undertale 'verse or even other AUs like Underswap. That means the really polished, high-kudos stories are a smaller pool. 'Bone Appetit' used to be a popular one that played with the whole chef dynamic, but I think the author orphaned it. Searching by 'Underfell' and then looking through the Sans/Frisk tag is your best method.
Sometimes you'll find gems cross-posted from Tumblr or FanFiction.net, but AO3 tends to have the most concentrated quality for this niche.
The other thing is, top-rated can mean different things. A dark, violent slow-burn might have fewer kudos than a fluffier piece, even if the writing is technically better. So I'd recommend reading a few of the highest-kudosed ones, then maybe checking bookmarks of authors you like to dig deeper.

Man, finding great Sans fanart is like digging for gold—there's a ton out there, but the real gems take some effort! I usually start with platforms like DeviantArt or ArtStation, where artists pour their hearts into detailed pieces. Tumblr’s also a hidden treasure trove if you know the right tags (try #sansundertale or #undertale fanart).
For curated stuff, Pixiv’s Japanese artists offer unique styles, though navigating it can be tricky without an account. Don’t skip Twitter/X either; many artists post WIPs or commissions there. My personal hack? Follow fanart retweet accounts like @UndertaleArt—they aggregate the best stuff so you don’t miss out.

Man, finding great 'Undertale' fanart is like stumbling into a treasure trove! DeviantArt was my first love for Sans and Papyrus content—some artists there put insane detail into their skeletal duo interpretations. I once spent hours scrolling through tags like #undertaleau or #sansfight, discovering styles from minimalist ink sketches to hyper-realistic digital paintings. Tumblr’s another goldmine if you curate your follows right; reblog chains often lead to hidden gems.
For something more niche, check out artists on Pixiv (though the interface can be tricky). Japanese creators often add unique twists, like kimono-clad Sans or chibi Papyrus with exaggerated expressions. Patreon’s good for exclusive pieces, but I’d recommend following artists on Twitter/X first to preview their work. Seeing how they animate Papyrus’s scarf or Sans’s glowing eye in motion? Chills every time.

Underfell Sans and Underfell Frisk have this fascinating dynamic that's way darker than their original counterparts. Sans in this AU is way more aggressive and sarcastic, almost like he's constantly on the edge. Frisk, on the other hand, is still the determined human, but in Underfell, they're often portrayed as more hardened or even ruthless. Their interactions are full of tension—Sans doesn't trust them at all, and Frisk has to navigate his hostility while trying to survive the brutal version of the Underground. It's like a cat-and-mouse game where both are predators in their own way.
What really stands out is how their relationship flips the script. In the original, Sans is the laid-back guy who eventually becomes a friend or even a protector. Here? He's more like a looming threat, testing Frisk's resolve at every turn. Some fan works even show moments where Frisk earns a grudging respect from him, but it's never easy. The Underfell AU really amps up the 'kill or be killed' vibe, and their relationship embodies that perfectly. Makes you wonder how much trust can even exist in a world that cruel.

The 'Undertale' fandom has some of the most creative fanart I've ever seen, especially when it comes to AUs like Nightmare Sans and Dream Sans. For high-quality pieces, I usually start browsing on DeviantArt—there's a treasure trove of artists who specialize in darker, more intricate designs for Nightmare Sans, while Dream Sans often gets softer, ethereal treatments. Tumblr’s also a goldmine if you dig deep enough; tags like '#dream sans' or '#nightmare sans au' pull up hidden gems from indie artists who don’t always get mainstream attention.
Another spot I swear by is Pinterest. It’s like a rabbit hole of interconnected art boards—once you find one piece, the algorithm keeps suggesting more. Twitter (or X) has a vibrant community too, especially during AU-themed art weeks. Just follow hashtags like '#undertaleau' or '#dreemurrfamily', and you’ll stumble upon threads where artists drop WIPs or full pieces. For something more curated, check out artists like Zarla or Sour-Appled on Tumblr—they’ve defined a lot of the AU’s visual lore. Honestly, half the fun is losing hours to retweets and reblogs, discovering artists who put wild spins on these skeletons.

The dynamic between Underfell Sans and Underfell Frisk is just dripping with tension, and that's exactly why fans love shipping them. Underfell's darker, edgier universe turns their interactions into this delicious push-and-pull of aggression and grudging camaraderie. Sans is more openly hostile, while Frisk is either fighting back or trying to navigate his sharp edges—it’s a recipe for fanfic gold.
Plus, the AU’s aesthetic amps up the appeal. The red-and-black color schemes, the rougher dialogue, even the way Sans’ smirk feels more dangerous—it all adds layers to their relationship. Fans latch onto that contrast, imagining scenarios where their clashes soften into something deeper. Maybe it’s the appeal of ‘enemies to lovers,’ or just the thrill of exploring a grittier version of their bond. Either way, it’s hard to resist.

Underfell Sans is this snarky, battle-hardened skeleton who's seen way too much bloodshed to trust anyone, while Underfell Frisk is a ruthless survivor with a 'kill or be killed' mentality. Their dynamic is like a twisted game of cat and mouse—Sans constantly tests Frisk's limits, throwing sarcastic jabs and traps their way, but Frisk just smirks and plays along, relishing the challenge. It's not your typical hero-villain clash; both are morally gray, but Sans has this weird, almost grudging respect for Frisk's tenacity. He might call them a 'dirty brother killer' one minute, then begrudgingly admit they're the only one who could possibly 'clean up this mess' the next. Meanwhile, Frisk sees Sans as this unpredictable wild card—annoying but too powerful to ignore. The tension is electric because neither backs down, and their exchanges are laced with this eerie mix of hostility and reluctant camaraderie.
What fascinates me is how their personalities mirror each other's flaws. Sans' cynicism clashes with Frisk's pragmatism, but both are products of Underfell's brutal world. Sans hides behind humor and detachment; Frisk wears cruelty like armor. When they interact, it's less about good vs. evil and more about two broken people circling each other, waiting to see who cracks first. The fandom loves to explore this—whether through fanfics where they begrudgingly team up or animations where their fights are downright theatrical. It's the kind of rivalry that makes you root for both, even when they're at each other's throats.

Underfell Sans is such a fascinating twist on the classic character—way more aggressive and sarcastic than his original counterpart. In this AU, he’s constantly testing Underfell Frisk, throwing sharp quips and brutal challenges their way. Their interactions feel like a high-stakes game of cat and mouse, with Sans sizing up Frisk’s every move. He’s not just messing around; there’s a real edge to his humor, like he’s waiting for Frisk to slip up so he can pounce. The dynamic is tense, almost like a twisted mentorship where Sans alternates between mocking and genuinely trying to scare Frisk off. It’s way darker than the original game, and that’s what makes it so gripping.
What really stands out is how Sans’s dialogue shifts depending on Frisk’s actions. If they’re violent, he’s even more ruthless, almost like he’s disappointed but not surprised. If they’re merciful, he still doesn’t fully trust them, but there’s this weird grudging respect. The way he toys with them in battle—dragging out the fight just to see how they react—is classic Underfell. It’s less about goofy puns and more about psychological mind games. Honestly, it’s some of the most intense character writing in any 'Undertale' AU.

Finding great Core Frisk fanart is like hunting for hidden treasure—you know it's out there, but sometimes you gotta dig! My go-to spots are DeviantArt and ArtStation; both platforms have artists who pour their souls into detailed, emotionally charged pieces. I stumbled upon this one artist who reimagined Core Frisk in a cyberpunk aesthetic, and it blew my mind. Tumblr’s also a goldmine if you search the right tags—just be prepared to fall into a rabbit hole of AU interpretations.
For something more curated, check out Pinterest boards dedicated to 'Undertale' fanart. Some creators link back to their Twitter or Patreon, where they post exclusive WIPs. And don’t overlook niche Discord servers—they often share hidden gems you won’t find elsewhere. The key is patience and following artists who resonate with your vibe. Half the fun is the journey!
