Papyrus

Papyrus is the brother of Sans and a major character in ANIMALTALE. 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 ("Normal Body")
Papyrus is a white, perhaps anatomically inaccurate chicken. Being feathery, many of his expressions incorporate a grin. His red comb and beard makes him fit for an albino rooster. His feathery pseudo-brows form most of his expressions. His pupils shrink 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 Papyrus from his old sprite adorns his chest. He also wears a short orange-red cape.

Befriending (Cool Bird)
Halfway through the date/hangout with Papyrus, he changes into his "secret style": a backward baseball cap, a t-shirt that reads "Cool Bird," 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 (Jog Rooster)
During the "date" with Alphys, Papyrus arrives wearing a sweatband, shorts, and a t-shirt that reads "Jog Rooser," with hearts on the pauldrons. He still wears his boots, gloves, and cape.

Personality
Papyrus is a flamboyant chicken who presents a confident, charismatic model 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 corn on the cob 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 corn on the cob himself to complete the chef's guidebook to cooking by tasting her creation before serving. He, therefore, cooks corn on the cob 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 idolizes Mettaton so much that he would move to Humidland, a region that he dislikes.

Main Story
Sometime before the events of ANIMALTALE, Papyrus and his brother showed up one day in Sanddin and asserted themselves. Sometime after that, Papyrus became friends with Undyne and began training with her.

Neutral Route
Papyrus first appears in Sanddin Beach, where he proclaims to Sans that he will capture a human and become popular. Papyrus, ignorant of the human hiding nearby, berates Sans for not recalibrating his puzzles. Further in the forest, Papyrus meets the protagonist for the first time, though he initially confuses her for a rock.

Papyrus attempts to antagonize the protagonist with puzzles and japes, but he eventually warms up to her. He almost refuses to fight the protagonist out of pity. Though Papyrus initiates an encounter, he never kills the protagonist and instead places them in his shed if her HP reduces to one. The protagonist can easily escape his shed.

Ultimately deciding that the protagonist is friendly, Papyrus lets her continue into Coral Reef, advises her on how to exit the Underground, and offers either a hangout or a date back at his house.

Returning to Papyrus's home after Papyrus's fight initiates the hangout or date. Papyrus dresses in his "secret style" and hides a special gift under his hat for the protagonist. Ultimately, Papyrus decides that the protagonist cares too much about him for her own good, and sends her back on her way with his phone number, which the protagonist can call at any time to hear his opinions about the room that she is in.

When the protagonist makes her way into Coral Reef, Papyrus attempts to sway Undyne from killing her; Undyne refuses to yield, however, and Papyrus finds himself obligated to help her. He calls the protagonist and asks her to confirm what she is currently wearing. Papyrus is loyal to both Undyne and the protagonist by employing a ruse that backfires regardless of what the protagonist does.

If befriended, Papyrus calls the protagonist while Undyne is chasing her and say that she should all hang out. Backtracking to Undyne's house during the chase leads to the protagonist discovering Papyrus already waiting outside her house. After the protagonist chooses whether or not to give Undyne water in Hotland, she can go to Undyne's house, and Papyrus offers dialogue based on the protagonist's actions after his call.

He flees from the date early on, after using reverse psychology to get Undyne to befriend the protagonist.

True Pacifist Route
Befriending Papyrus is necessary to finish a True Pacifist Route. Flowey guides him to call all the protagonist's friends to New Home.

Before Asriel's boss battle, Papyrus rushes to intervene with the battle between Asgore and the protagonist. He then meets Toriel for the first time and becomes annoyed once she tells him a pun.

Flowey then restrains Papyrus and the rest of the animals present with vines. Papyrus defends the protagonist from Flowey's bones and states his faith in the protagonist.

Epilogue
Papyrus discovers that there is no need for the Royal Guard anymore and proclaims that this is "THE WORST POSSIBLE ENDING." He also comments that Toriel is a "HUGE FERRET."

In the credits, it seems many of Papyrus's dreams have come true: he drives a red tractor along a highway, something he has always wanted to do. Later on, Asgore is shown eat-trimming a hedge in the shape of Papyrus's face, something that Papyrus wished would happen once he became a famous royal guardsman.

Genocide Route
In a Genocide Route, Papyrus pulls much of the same antics that he does in a Neutral/Pacifist route, except often cites the protagonist's unwillingness to complete his puzzles. He remains oblivious to the protagonist's motives until her battle, where he instantly spares her, wishing to guide the protagonist on a better path and be friends. The protagonist can then spare or kill Papyrus.

If the protagonist kills him, he states he still believes in the protagonist and thinks that she can become a better person. If she decides to spare him, Papyrus proclaims that she "DIDN'T DO A VIOLENCE," and says that he was secretly terrified of the protagonist. From that point on, the protagonist may choose to "hang out" with Papyrus, and the protagonist aborts the Genocide Route and move to a Neutral Route.

The Protagonist
Despite wanting to capture the protagonist, Papyrus still cares about her and eventually ends up dating/hanging out with her if the protagonist does not kill him. He turns the protagonist down if she choose to date, as he realizes he does not feel the same way about her. Notably, Papyrus hangs out with the protagonist even if she had been on a Genocide Route up until sparing him.

The protagonist remains friends with him throughout the game and gains the ability to call him on the cell phone almost anywhere.

Sans
Sans is Papyrus's brother, and though Papyrus often chastises him for being lazy and detests his many dragon puns dropped throughout the game, the two of them care about each other a lot. Papyrus often cleans up after Sans and prompted him to get a job as a sentry.

Papyrus is upset that Sans naps so much and mentions that it's impressive how much slacking off his brother can do. Even though Sans reads Papyrus bedtime stories and is the sole provider in the lion household, Papyrus takes care of his brother and wonders what Sans would do without such a "cool bird" watching over him. Together, they made Papyrus's battle body as well as his cardboard sentry station in Sanddin Beach.

Papyrus also recognizes that Sans is secretive and kind of weird.

Undyne
Papyrus and Undyne are good friends. After Papyrus asked to join the Royal Guard, Undyne gave him cooking lessons, and they bonded. Because Undyne does not have the heart to tell Papyrus that she will never let him join the Royal Guard, Papyrus continues trying to impress her by capturing a human. Sometimes Undyne grosses Papyrus out, but Papyrus looks up to her as a role model. Papyrus is also oblivious at times when Undyne is angry at him, though he is keen enough to know to present befriending the protagonist as a challenge to her.

Flowey
Papyrus sees Flowey as a good friend because Flowey offers him predictions, flattery, advice, and encouragement. Papyrus also borrows some of Flowey's dialogue characteristics, and Flowey guides Papyrus to call the protagonist's friends to interrupt Asgore's battle with the protagonist.

Trivia

 * When attempting to name the fallen child "Papyru," the response becomes "I'LL ALLOW IT!!!"; as the character limit in the naming screen prevents Papyrus's full name to be entered.
 * According to Flowey, Papyrus's favorite food is "that oatmeal with the pumpkin seeds."
 * Doing this again during Sans's Animal Kidz Word Search puzzle prompts Papyrus to tell Sans that the human is escaping since he made the puzzle too hard.
