Papyrus (Undertale)

Mettaton: Like many monsters in the Underground, Papyrus idolizes Mettaton as a celebrity. He owns several Mettaton-related items MTT, watches his show, and calls him his "Favorite Sexy Rectangle" in one of the alternate calls in Hotland. Papyrus calls the ghost that was once Mettaton "HAPPSTABLOOK, THE HAPPY GHOST", which is not entirely correct but is his headcannon. Otherwise, it is never established that he officially meet in the main story. In one of the calls to Papyrus in Hotland, he mentions that he hates Hotland in several calls, but knowing that Mettaton performs there, he corrects himself and says that he wishes he lived in Hotland. He also mentions that he is jealous that the player performed with Mettaton in one of his shows. Alphys: She and Papyrus are mutual followers in the UnderNet and seem to get along quite well, it is possible that Papyrus does not have any real information posted on his profile, since when he appears at the end of the date between the protagonist and Alphys, she does not seem to recognize him.

Sans: He is Papyrus's older brother, and despite constantly nagging him to stop being so lazy and making so many bad puns throughout the game, the two care about each other a lot. Sans refers to his brother as "cool." Papyrus frequently cleans up the mess of Sans, saying that "Sans is lucky to have a cool brother who looks out for him." It was Papyrus who convinced Sans to get the guard position outside the Ruins. Additionally, during the encounter with Shyren, the player can sing with her to form a small concert. If Papyrus is alive, Sans will sell concert tickets made of toilet paper. If Papyrus is dead, "a hooded figure will watch the commotion in the distance." There is a strong implication that this figure is Sans. Undyne: Papyrus and Undyne are good friends. As Captain of the Royal Guard, Undyne takes Papyrus under her wing to train him, though instead of giving him fighting lessons, she gives him cooking lessons, as she believes he's too friendly to join the Royal Guard. Still, Papyrus continues to do his best to capture a human so that Undyne will also recognize him and allow him into the Royal Guard. Although Papyrus detests Sans's jokes and pranks, he is very different with Undyne, laughing at her puns and even changing his mind on occasion according to Undyne's opinions and tastes, thus showing that he admires her and wants to be on good terms with her as good friends. Flowey: In an optional conversation with Sans, it is implied that Papyrus has encounters with Flowey, and that he receives from him praise, advice, encouragement and predictions, probably for Flowey's benefit. Flowey is the one who tells Papyrus to gather his friends at the beginning of the fight with Asgore to stop it and later be captured by Flowey himself. Thanks to Papyrus we can intuit which timeline Flowey was trying to reach before being interrupted by Frisk, because Flowey could never defeat Sans because it was too difficult or impossible.

He's proud and a bit dumb. His main motivation is to become "the newest member of the Royal Guard."

Some time before the events of Undertale, Papyrus and his brother appeared one day in Snowdin Forest and settled there as residents. Some time later, Papyrus befriended Undyne and began training with her.

He says that for this to happen, Papyrus had to come at midnight to plead her to train him. At first, Undyne sends Papyrus back home, but the next day she starts training him.

He also mentions that the two of them made his "battle suit" (as Papyrus calls it) a few weeks, or about 4 to 6 weeks, before Frisk arrived in the Underground for a costume party. He hasn't taken it off since, and to wash it, he bathes in it.

He is a tall skeleton, who uses a red cape, red boots, red gloves and something similar to a plastic armor, although it may not seem like it, he is the younger brother (and not older) of Sans.
