Undyne is the Captain of the Royal Guard and adoptive daughter of Gerson. Undyne had always had a rough childhood, as she always came off as abrasive. When she first met Sans and Papyrus, Papyrus and Undyne became inseperatable! They of course grew up to be best friends, and the two often goof off with one another. When Undyne isn't leading the guard, she's often at the lab visiting her girlfriend, Alphys! Undyne HATES Mettaton with a passion.. She never liked his flamboyant personality...or the fact that Mettaton has a history of being incredibly salty with her. Undyne can be very kind and compassionate towards her peers and family, and often uses those emotions to motivate herself when stuck in a rough patch.  Despite her incredible health, Undyne cannot keep herself away from sugary foods, especially Ramune or hard candies. keep her away from sour stuff though! She's allergic! Much like Sans, Undyne has a high love for anime, and she is addicted to Fullmetal Alchemist! Yet despite this, her phone's ringtone is the American English version of the original Sailor Moon theme song! Undyne's weapon of choice, aside from her spears, is a Bow! She has the ability to shrink her spears down to the size of arrows and launch multiple shots in one go! these spear arrows can pierce through most material, but can easily be counteracted with opposing Magic. Undyne is the only monster in the underground to wield Two Different Weapons with her souls magic!!

[Undyne is loud, emotional and adventurous. She's got a bit of a Jasper like voice from Steven Universe, but not as low or raspy sounding. Shes got a medium tone to her voice. Don't be afraid to get loud for this one!]
