The collective writings of CourierNew have word for word some of the best prose I've seen in fanfic, while carefully managing its tone to match that of the game while making it look effortless.

Synopsis Asgore and Toriel try to work out their past.
Main Character(s) Asgore, Toriel, Frisk

Recommendations

The emotional core of this story is intense and sincere, and you feel yourself get inside Asgore's head in particular, and the end feels cathartic

This story has an interesting theme surrounding reconciling old and new identities, and while I might not personally agree with its conclusions it explores it in a compelling manner.

Author(s) Outskirts of Nowhere
Word Count 40,000
Synopsis In spite of Flowey's pleas, another reset happens. But Flowey remembers what Frisk did for him, and struggles to stop them going down a dark path. The results are... unexpected.
Main Character(s) Flowey, Frisk, The Player, Gaster, Undyne, Sans
Other Tags Pacifist Ending, Attempted Genocide, Reality Breaking
Recommendations

This has a strong opening and a compelling exploration of Flowey. It gets weaker near the end as Ganon seems to Hijack it as it were, but I'm fond enough of the start to still recommend it.

Recommendations

To keep the quality high, the writer set themself some rules, like "no resets", "no apologia", "no Gaster" and "Sans never loses his chill". The result is excellent.

Name Spectrum
Author(s) 1nky
Word Count 271,000
Synopsis After the end of Frisk's journey, a mysterious man appears and takes Sans away. Papyrus, Frisk, and Undyne are left with the task of saving him... And making sure they don't end up dead themselves.
Main Character(s) Sans, Papyrus, Frisk, Undyne, Alphys, Gaster
Other Tags Gasterblaster AU, Post-Pacifist
Recommendations A story (in the author's words) about the power of friendship, teamwork, and body horror. Well-written, dark, and emotional, the story does an excellent job of exploring Sans' and Gaster's backstory creatively, as well as illuminating Sans' flaws.

Even though the story's main focus is on Sans and his past, everyone gets a chance to help in the 'present day' struggle - especially Undyne, who practically (and sometimes literally) carries the team.

Name Trust (PDF Version)
Author(s) KeetahSpacecat
Word Count 75,000
Synopsis Reports have been circulating around Snowdin of strange skeletal creature sightings. After two weeks of his trash being raided, Grillby decides to investigate. What he finds turns out to be a sign of something twisted going on in the Underground.
Main Character(s) Sans, Papyrus, Grillby, Royal Guard Dogs
Other Tags Pre-Game, Babyblaster AU, Gasterblaster AU, Recovery, Dad Grillby
Recommendations The pioneer Babyblaster AU / adoptive dad Grillby fic. A prequel of sorts to the main story of Undertale, focusing on the inhabitants of Snowdin.

The development of Grillby as a father, alongside the skeleton brothers slowly opening up to him is a joy to read. However, it is not for the faint of heart, as it deals with very heavy themes such as past abuse and trauma.

Name What Are Friends For
Author(s) IchikoWindGryphon
Word Count 140,000 (Ongoing)
Synopsis After Undyne finds out a secret Papyrus had been keeping from her, the traumatic past of the skeleton brothers comes to light.
Main Character(s) Papyrus, Undyne, Sans, Gaster, Grillby
Other Tags Gasterblaster AU
Recommendations Has an interesting spin on Gaster's past and the events of the monster-human war. As a warning, as events get closer to the present, things get quite dark.- Curry
Name To the Feral and the Broken
Author(s) TopazShadowwolf
Word Count 16,000 (Ongoing)
Synopsis A chance meeting between a lonely Boss Monster and a feral, fearful young man changes both their lives.
Main Character(s) Toriel, Sans, Papyrus
Other Tags Gasterblaster AU
Recommendations An interesting alternate timeline to the game, where the skeleton brothers couldn't deal with Gaster's abuse and ran away to grow up in the wild. Slow pace, but really good so far. - Curry
