Undyne is a fish-like monster with long red hair, blue scales, a big yellow eye and an eye covered by an eyepatch, fish-like ears, red lips and sharp yellow teeth. She wears a black short shirt with a red outline of a heart on it, long red gloves, black pants with a wrestle mania belt and long red boots. Undyne is merciless almost as much as Asgore. Does get angry easily, doesn't get in a fight immediately either, never let's down once shes in a fight. Loves sparring with Papyrus. Bisexual.
