Me: Last one 

Appearance

Alphys is a yellow, reptilian monster of similar height to the protagonist. She has scales, round glasses, protruding teeth (which seem to vary between two and four depending which way she faces), and normally wears a white lab coat. However, she wears a polka dot dress on her date with the protagonist.

Personality

Alphys is a nerdy, shy recluse with a fondness for human anime and manga. She has crushes on multiple characters (some mild, others more serious), but struggles to communicate her feelings.

Alphys is filled with guilt and insecurities about herself and her accomplishments. After she accidentally created the Amalgamates while experimenting with determination, she told nobody and became depressed.
