Papyrus

Papyrus is one of the major characters from the Undertale game.

Papyrus is the brother of Sans. His main motive is to capture a human so he can become a member of the Royal Guard, and finally have friends and popularity.

Normal ("Battle Body")
Papyrus is a tall, perhaps anatomically inaccurate skeleton, with a skull more vertical and geometric than his brother. Being skeletal, many of his expressions incorporate a toothy grin. His eyes resemble vertical slits; his skeletal pseudo-brows form most of his expressions. He has eyeballs which show at times when he is experiencing strong emotions.

He wears his "battle body," an outfit that he created for a costume party. It includes a white chest plate with gold trim, Coquelicot gloves with a golden trim, blue briefs with a golden belt, and knee-high, Coquelicot boots. A symbol that resembles that of Starman from the MOTHER series adorns the chest plate. He also wears a short orange-red cape.

Befriending (Cool Dude)
Halfway through the date/hangout with Papyrus, he changes into his "secret style": a backward baseball cap, a t-shirt that reads "Cool Dude," small shorts with buttons, gloves with striped trim, knee-high socks, and sneakers. He also wears basketballs on his shoulders, likely Mettaton's MTT-Brand FashionBall.

Alphys Date (Jogboy)
During the "date" with Alphys, Papyrus arrives wearing a sweatband, shorts, and a t-shirt that reads "JOGBOY," with hearts on the pauldrons. He still wears his boots, gloves, and cape.

Personality
Papyrus is a flamboyant skeleton who presents a confident, charismatic image of himself. He works hard and, despite his brash personality, is kind at heart. He is optimistic and innocent even when the protagonist beheads him in a Genocide Route. He is also occasionally oblivious and nonobservant, but can be cunning at times, as seen when he uses reverse psychology to trick Undyne into befriending the protagonist.

Papyrus believes in others just as much as he believes in himself. He has so much faith in his abilities that he waited outside of Undyne's house all night and begged her to accept him into the Royal Guard. Seeing his persistence, Undyne offered to train him but instead gave him cooking lessons.

He cooks spaghetti in his spare time, though many characters seem to think that he is not very good at it. One of the reasons for this is because Papyrus never ate spaghetti himself to complete the chef's guidebook to cooking by tasting their creation before serving. He, therefore, cooks spaghetti only because everyone else loves to eat it, indicating he does not play favorites. He loves puzzles and japes, as shown in the numerous puzzles he prepares for the protagonist as well as his collection of "complex tomes about puzzle creation." Though advanced puzzles may seem cerebral, Papyrus also enjoys children's books and is somewhat childish with the decoration of his room. He also collects action figures.

Papyrus also watches Mettaton's TV shows, and admires Mettaton so much that he would move to Hotland, a region that he hates.

Abilities

 * Skeleton Physiology- Papyrus is a living skeleton.
 * Soul Manipulation- As a monster, Papyrus is capable of manipulating the souls of others.
 * Gravity Manipulation- Papyrus can manipulation the gravity within his intended target's vicinity by turning their soul blue, the induce in gravity causes the target to move slow and reducing their jumping capabilities.
 * Bone Magic- Papyrus can generate bones, and he can manipulate and craft them, as during his fight with Frisk, Papyrus crafted some bones spelling "COOL DUDE", a bone on a skateboard, and also manipulate the size of them.
 * Thermal Immunity- As a skeleton, Papyrus doesn't feel the effects of heat or cold, as he lived in Snowdin which is a town covered in a perpetual layer of ice and snow.
 * Skilled Cook- Papyrus cooks spaghetti in his spare time, though many monsters seem to think that he is not very good at it because he never ate spaghetti himself to complete the chef's guidebook to cooking by tasting their creation before serving. Though, Sans does admit his cooking is improving, he even says if he practices a year, Papyrus will be get it right. Also, Papyrus has been getting cooking lessons from Undyne.

Trivia

 * The costume Papyrus usually wears; he refers to it as his "Battle Body". It was made by himself and Sans for a costume party and according to Sans, he hasn't worn anything else since. Sans also mentions that at least Papyrus washes it, meaning that he wears it in the shower.
 * In contrast to his brother, Papyrus speaks exclusively in capital letters, being the only character in the game to do so. (Mettaton stops speaking in just capital letters when he transforms into Mettaton EX). Interestingly enough, the font used for his dialogue is also called Papyrus.
 * Papyrus has never seen a human before seeing Frisk, as said by Sans and evidenced by Papyrus mistaking a rock for a human while not reconizing that Frisk is a human upon seeing them.
 * Undyne implies that Papyrus regularly jumps out of the window in her kitchen, as according to her, he usually "nails the landing".
 * According to Sans, Papyrus finds difficulty in "interesting" places, as the day before they met Frisk, Papyrus got stumped trying to "solve" the horoscope.
 * During Sans's conversations with Toriel through the locked door, despite not knowing each other's names, Sans had told Toriel about Papyrus. On the True Pacifist Route, Papyrus was delighted when "Asgore's Clone" (Toriel) knew who he was.
 * Papyrus mentions in a phone call outside Gerson's shop that he (Papyrus) has an imaginary store that sells flames.
 * Papyrus dreams of driving on a highway on the Surface with the wind in his hair and the sun on his skin (despite being a skeleton and, as such, probably not having hair or skin). This dream comes true in the True Pacifist Credits.
