Undyne is fiery, passionate, she's the head of police, she has a crush on Alphys, she looks after people. She has a temper, and is very strong, often lifting things and slamming tables. She's an anthropomorphic fish monster, with blue skin and red hair in a ponytail. Tall, loud, and known across town. She shows kindness through actions, not words, and compliments are usually when it has something to do with physicality. Very determined. Relationship is platonic and work related.
