Alphys

Alphys is a female, reptilian monster that lives in the lab in western Hotland. She is the incumbent Royal Scientist, a position she was awarded by Asgore. Alphys is a yellow, scaled monster of similar height to a tall full grown human. Her posture is somewhat hunched over, giving her an appearance of nervousness, and showing she is infact taller. She has yellow scales, claws, and protruding fangs. An hourglass figure that is highlighted from her lab coat.

Alphys is a shy introvert who frequently stutters when she converses. She has low self-esteem, makes self-deprecating comments, and devalues her skills at times. True to her role as a scientist, Alphys is intelligent, analytical, and observant. She occasionally theorizes on matters.

Alphys is passionate in her interests. She often gets excited when sharing her opinions. Alphys's hobbies include enjoying human anime, manga, and video games. Alphys is also fond of shipping, writing fanfiction, and writing walkthroughs for games.  For the latter, Alphys prefers giving solutions as a last resort.

Alphys is filled with guilt and insecurities from her accomplishments.  Due to this, she has a tendency to procrastinate and write informally.  Socially, Alphys tends to be avoidant and anxious.  She also favors being appealing to others.

The Underground is the primary setting of Undertale. It is a large region within Mount Ebott that is separated from the Surface of the Earth. It houses the kingdom of Monsters, who are ruled by King Asgore, and formerly by his ex-wife, Toriel. The Underground has varying climates, and features six different areas: the Ruins, the frigid and wintery Snowdin, the marshy and cavernous Waterfall, the blistery and barren Hotland, the technologically advanced CORE and the Capital. The Underground's exit is blocked by the Barrier, which was placed by the Humans long ago. Anything and anyone can enter the Underground by descending into Mount Ebott.
