"The Red is strong with this one" - Flavor Text of Fell! Papyrus, if checked
Papyrus is the ruler of Snowdin, and brother of Sans. He is said to verbally and physically bully Sans on a regular basis. Since joining the Royal Guard he has been more abusive towards Sans. All of the monsters in Snowdin are afraid of Papyrus. He is regularly seen killing innocent monsters as he follows the "Kill or Be Killed".
Papyrus shares many physical similarities to his Undertale counterpart. He is about three inches taller, at 6' 3", with good posture and bleached white bones. He is, of course, a skeleton, and he has a crack in one of his eyesockets. He wears a tattered scarf and black spiky armor. He wears black leather pants in contrast to his Undertale counterpart's jean shorts. He wears a red belt with a gold buckle. He, like everyone from Underfell, has sharp fangs. He wears long red gloves. According to Chara, he is definitely not very cuddly looking.
In most interpretations of Underfell, Papyrus is a cold, ruthless Royal Guard commander. He cares little about the well-being of other monsters, and will not hesitate to slaughter anyone just to set an example. He rarely shows any emotion, and lacks any remorse for his actions, no matter how gruesome or merciless. Papyrus is perfectly fine with manipulating or torturing others to get what he wants. The only people he shows any sort of bond with is his brother, Sans and the head of the Royal Guard, Undyne. But Sans isn't safe from Papyrus' wrath, as their relationship revolves around their hate towards each other. He verbally and physically abuses Sans. Deep down, he's actually doing all these things to act tough and loves his brother. But no one sees that...not even the greatest of friends.
Powers and Abilities Edit
Papyrus is a lot more powerful than his Undertale counterpart, perhaps becuase he lacks the kindness his counterpart has. He would murder humans numerous times without a second thought. Like his Undertale counterpart, he can manipulate bones, which often glow a reddish color. Like Sans, he can also use telekinesis on a living soul.
Like in Undertale, Papyrus tries to capture Frisk with puzzles, only without any help from Sans. Different than Undertale, however, the traps are violent, and Papyrus attempts to kill Frisk.
As Frisk and Flowey attempt to escape Snowdin, Papyrus will block the way at the end side of the quiet town. Papyrus' fight is similar to the one in Undertale, only he can also use telekinesis like Sans. The fight will end with Papyrus only knocking Frisk out and locking them up in the garage, as long as Frisk continues to show mercy for the True Pacifist timeline.
As it is stated above, Sans is the only other monster Papyrus seems to possess any form of bond with other than Undyne. Unfortunately, their relationship is largely founded on and primarily revolves around pain, bickering, and intimidation from Papyrus to Sans, to the point where he even makes Sans call him "Boss," as opposed to "bro." Despite all of this, at times it appears to be implied that he cares deeply for his brother, and is only so hard on him to protect them both.
Undyne is close to Papyrus, and one of his only friends. While their friendship is tense, like most other monsters of the Underground, they get along a lot better than other monsters do.
True Pacifist timeline: Papyrus tries very hard to kill Frisk and Flowey. He sets out deathtraps and dangerous puzzles for Frisk. He then attempts to battle Frisk face-to-face. This is where Frisk goes on saying that they believe that anybody can be a good person if they just try. Papyrus thinks for a moment before knocking Frisk out. Flowey then witnesses Papyrus locking Frisk up in the torture room, letting them rest there. He leaves them spaghetti - which heals 20HP - and a note with his phone number so they can call him anywhere at any time as a 'friend'.
Genocide Timeline: As Frisk ruthlessly murders every creature they see, they will run into Papyrus and Sans. Frisk will bypass every trap Papyrus adds to capture or kill Frisk with. Frisk will then come face-to-face with him and battle. Frisk and Papyrus will still have to fight like in the Pacifist timeline, but Papyrus will die in one hit. Papyrus believes he died in vain and says that they will still have to face Undyne and Asgore before dying.
He's very oblivious to Flowey. If befriended, he and Flowey become acquaintances.
Underfell Game Differences Edit
In the Underfell fan game, Papyrus owns a cat named Doomfanger, which Sans is forced to take care of. The relationship between him and Sans is milder, and his position in the Royal Guard is unmentioned as of version 1.0.2.
