Undyne

**Undyne** is the captain of the Royal Guard and Alphys's girlfriend. She lives in Waterfall, neighboring Napstablook.

## Appearance

Undyne is a tall fish monster with blue scales, flowing, spiky red hair pulled back into a tight ponytail, blue head fins with red detail, a yellow eye, and a thinner but muscular build. notably muscular in her arms.

Undyne is usually seen wearing a ripped black top with a broken red heart on the chest, black leggings, torch red latex boots, and torch red fingerless gloves. She also wears a black eyepatch over where her left eye would be, gold earrings on her head fins, matte red lipstick, and mascara on her lower eyelashes.

## Personality

Undyne is nearly as merciless as Asgore. She can also be derisive and condescending, especially towards her right-hand man Papyrus, often mocking and belittling him, sometimes doing the same to Sans. Despite this, she seems to enjoy sparring against him, and was impressed when he managed to win against her, rewarding him with the belt medallion he currently wears on his belt. Undyne also can be quite vulgar. She may be a bit impatient, as she once burnt herself on something Papyrus was cooking, while it was still grilling.

Despite her abrasiveness, she is shown to be very loving to her girlfriend, Alphys. She also seems to eventually grow a soft spot for Frisk. She also feels sorrow if she has to kill Papyrus, shown in a hypothetical betrayal route encounter.

## Relationships

### Alphys

Alphys and Undyne are currently dating. They are really close and genuinely love each other and are often seen hanging out and going on dates. They also tend to give each other gifts; Alphys gave Undyne her clothing and Undyne gave Alphys the spiral glasses she wears.

### Papyrus

Undyne and Papyrus are always seen butting heads, since the latter always tries to challenge her. Undyne beats him every time and reminds him of his place. However, he manages to best her once. This leads her to reward him with a WWE wrestling belt medallion.

In the hypothetical betrayal route, when he had defended Frisk from her, Undyne ends up killing him. However, she is in tears and clenching her teeth, showing remorse for killing him, or is at least very upset. This implies she cares for him, and hates "having" to kill him, perhaps meaning they may be friends.

However, in the closure route, she is seen looking ahead, seeming to be processing something, whilst Papyrus motions towards presumably Frisk with his hand, likely trying to get her to contemplate befriending Frisk. This may imply she may be willing to hear him out sometimes. Despite this, she is often seem making fun of him and laughing at him, sometimes even insulting him.
