Undyne is a character in the 2015 indie-game Undertale. She is the leader of the Royal Guard and a boss encountered in Waterfall.

Appearance
Undyne is a fish-like humanoid monster, having scales and a long bright red ponytail. She always shows a pair of protruding teeth along with fins on the side of her head. Undyne also wears an eyepatch on her left eye, meaning that she lost it or just uses it for her own taste. However, she also has yellow sclera but it turns black when she is fatally wounded.

Undyne is shown in her first appearance wearing a tough armor with boots, gloves and a helmet. Later at her house, Undyne wears casual clothes like a sleeveless shirt, blue pants and brown shoes.

Personality
While Undyne takes serious her goals when she is focused on killing the protagonist and get the last soul so Asgore can break the barrier, she can also be friendly, honorable and honest to everyone he meets especially Papyrus, Alphys and her friends from the Royal Guard.

Undyne is also encouraged and competitive as shown when Papyrus said she's "not up to the challenge" at having Frisk as her friend and realized that having them as her friend would be her "ultimate revenge". Despite that, Undyne always keeps her kind attitude and cares for those who she considers her friends. She is secretly in love with Alphys, the royal scientist of the underground who also shares the same feelings towards Undyne.
