Summary
Alphys has been in town for some time now, but not made a whole lot of friends. She has not even developed a good relationship with her student and neighbour who lives next door and seems to hate her.
Susie has had a hard time of everything and Hometown is looking like more of the same. She starts making friends for real though, and things seem like they might change. But there is still so much she can't let anyone find out about her.
A particularly rainy day and a leaky roof leads these two into each other's lives more than they had seen coming. But now that Alphys knows what she knows she can't exactly back out, can she?

Summary
Alphys had been working in the royal labs for almost a month now, and it was a dream come true. But then, one day, she gets promoted from Regular-Intern to Doctor-Gaster’s-Personal-Intern. You know, the sinister, terrifying Royal Scientist, that nobody really knows anything about and what he does in his lab most of the time.
She was terrified.

Bookmark Notes:
"Once she recovered enough to look presentable, she straightened her posture as best as she could and knocked on the door.
Immediately, it slowly creaked open, to reveal… a skeleton who was definitely not Dr. Gaster."
also
"It would have been a fairly basic lab setup, if it weren't for the fact that it was the basic lab setup for various fields of science all mashed into a single room. And-- was that Sans? Leaning against a table in the corner? How did he even get in here--"

The Trans-Underground Alphys-Carrying, Match-Making Road Trip by Taliax
Fandoms: Undertale (Video Game)
02 Mar 2021
Tags
Summary
From her secret security camera, Alphys gets too invested in Sans's relationship with the voice behind the door. This wouldn't be a problem if Mettaton didn't decide to take her ship into his own hands.
Trying to catch up with a battery-powered robot is hard work, but telling the truth is even harder.

Summary
It's Alphys's freshman year at Ebbott University, and she is ready for it. There's so much to look forward to -- rooming with her best friend Mettaton, getting to focus in on her passion for robotics and engineering, living on campus for the first time...
She was not prepared for a gorgeous fish lady to come crashing into her life, or for her friend count to more than double.
It was going to be an interesting year.

Summary
"Despite having been the royal scientist for quite some time, Alphys never really felt like the title held any weight. Sure, the king came to the lab from time to time, forcing her to frantically clean up the cups of noodle and boxes of anime she found in the dump when she heard news of his arrival. Sure he gave her tasks from time to time, but they were meaningless. Checks on the Core—it wasn’t like she was the one doing physical maintenance, just checks and programming for self-repairing functions to work. She never even went inside the Core. Not after what happened to…well, never mind."
An Undertale prequel that looks in-depth into the events of the True Lab

Summary
‘The human was a smudgy reflection of what Undyne was led to believe a ‘human’ was. The more she observed their unmoving body, the more the human resolved themselves into a pattern of inky-darkness, a cowardly, pathetic reflection of her preconceptions.
It was over. Hours of panic, hopelessness, crazed desperation… All vanquished in an instant. Her duty fulfilled…’
Undyne the Undying manages to defeat the human, but at what cost?

Summary
Alphys splayed her fingers as far as they could go, but the next piano key was always just out of reach. Her claws stumbled across the wrong notes, slipping in the water dripping from her eyes.
This was stupid. She was so, so stupid.
(Alphys attempts to play the song that Undyne wrote for her, since Undyne is no longer able to.)
