Me: let's do this

Appearance

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, orange-red gloves with gold trim, blue briefs with a golden belt, and knee-high, orange-red 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.

The first and only appearance of Papyrus's "JOGBOY" outfit

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.
