What? Wh-what am I watching on my phone?
It's schoolwork, of course. A... animated schoolwork... and...
H-hey, Kris, have you chosen a partner yet?
Alphys to Kris
Alphys is a yellow lizard-like monster with buck teeth. She can be seen with square glasses, a light green shirt, a green jacket, brown pants, and a red tie.
Alphys is a shy, nerdy monster who appears to try her best in guiding her students to succeed. She is often seen as a recluse like her depiction from Undertale and still retains her love for anime, notably "Mew Mew Kissy Cutie", as can be seen when checking her computer and the bulletin board in the Library. Alphys also shows a fondness for superhero comics and a television series called The Symptons, a reference to the American sitcom The Simpsons.
She is first seen in her classroom, discussing a group project until the arrivals of Kris and Susie, where she encourages Kris to find a partner. As they are both latecomers, she sends Kris and Susie to get chalk for her in a supply closet and is not seen until the end of the game. After returning, she can be found in a small alleyway, waiting for "MewMew" to come drink milk out of a saucer.
- A picture of Everyman from Undertale can be seen in Alphys's alley drawn in graffiti in pink with its name next to it. As the Amalgamates do not exist in the Deltarune universe, it is unknown how or why anyone would be able to draw it.
- Alphys seems to have no idea who Undyne is, contrasting sharply with their relationship in Undertale.
- Alphys's cat's name, "MewMew", refers to Alphys's favorite anime in Undertale; Mew Mew: Kissy Cutie.
- Additionally, she admires Mew Mew: Kissy Cutie 2, unlike in Undertale, where she despises it deeply.
- Alphys has a screensaver of nature images and two buff superheroes embracing.
- In Deltarune, unlike in Undertale, Alphys has square glasses, inspired by John Egbert.
