Undyne

Undyne is passionate about everything that she does. She acts quickly on her ideas and is steadfast in her beliefs. Though she wants to defeat the Frisk, she also tries to be fair and offers an explanation of how Green soul works. Asgore taught her the value of pacifism, which is why Undyne sees the Frisk as "a wimpy loser with a big heart." When the Frisk first encounters her, she fights to further Asgore's plan of collecting seven human SOULs but, if the protagonist shows mercy, Undyne just as quickly defends them from Asgore.

She loves to help others and mentors Shyren and Papyrus in various skills. Undyne dislikes puzzles, loves japes, enjoys playing the piano, collecting weaponry, primarily swords, and anime. The latter she shares with her romantic interest, Alphys. Since Alphys told Undyne that anime is actually human history, Undyne regards human history as exciting and cool.

Alphys and Undyne love one another. Undyne first met Alphys in the Garbage Dump while searching for swords. She listened to Alphys's theories for hours on where the Garbage Dump's abyss led. The two became close friends soon after, with Alphys introducing her to anime at some point, although Alphys told her that they were history biopics about humans. They hang out often, and Alphys uses the seagrass throughout Waterfall to make a special frosty treat for Undyne. Alphys and Undyne also worked together to create some of the puzzles in Waterfall. At some point Undyne fell in love with Alphys due to her confidence in what she liked and her work, but didn't know how to express this.

Undyne thinks of Papyrus as a close friend. She is impressed by his persistence, but is concerned about his well-being and secretly does not want him to join the Royal Guard because she believes he is too kind to even fight. As a result, she teaches him how to cook in hopes for him to defer from joining. Undyne sometimes enjoys messing with Papyrus, but she often forgets that he usually takes things literally.

Undyne used to give piano lessons to Shyren, but one day she stopped coming – presumably after her sister fell down.

Undyne see Frisk as a friend. Nothing much beside they did hang out togger befor her house burn down.
