Who is Undertale’s Papyrus?  

Papyrus is one of the least powerful, but most charming, characters you meet during an Undertale playthrough. Though he arrives looking and sounding like an antagonist, set on capturing the player for a place in Undyne’s royal guard, Papyrus becomes a good friend for the journey, unless, of course, you kill him during the genocide run. 

Meeting Papyrus in Undertale

In terms of relationships with other characters in Undertale, Papyrus is Sans’ younger brother, and takes cooking lessons from the head of the royal guard Undyne.  Depending on who you befriend, and which route you head down, Papyrus can meet other characters too, and has a surprising disdain for the loveable Toriel. 

How do I beat Undertale’s Papyrus boss fight? 

How you go about the Papyrus boss fight is entirely dependent on which route you’re looking to complete – neutral, pacifist, or genocide – and the results massively change the outcome of the game. 

Papyrus fight: neutral route 

It doesn’t matter all too much whether you choose to kill or not kill Papyrus on a neutral run, especially your first. There are some changes to the dialogue at the end of the game dependent on which monsters you did and didn’t kill, including one in which Papyrus is king if he is saved, so if you want Sans to be in a good mood first time around, we recommend keeping his brother alive. 

Papyrus fight: pacifist route 

Not only do you have to spare Papyrus along with everyone else to complete the pacifist route, but you also need to date him. Yes, that’s right, we’re dating skeletons in the underworld. Once you’ve spared Papyrus, you can return to his house and complete a special friendship event, gaining Papyrus’ trust, so that you can also win over Undyne and continue on the pacifist route.

Papyrus fight: genocide route 

If you’re headed down the genocide route, you need to slay Papyrus before continuing with your adventure. This is probably the easiest of the three options as Papyrus poses no real threat to the player, never taking your HP below one, so you can just keep attacking until the battle is done. 

How old is Undertale’s Papyrus? 

As with most of the Undertale characters, Papyrus’ age is left up to the imagination of the player. Due to his height, ability to cook on the stove, and conversational skills, we can guess that Papyrus is an adult, more than likely a young adult of around 20 years old. It’s even more difficult to guess with characters like Sans and Papyrus, what with them having no skin and all, but all things taken into account, we think Papyrus is anything between 18-30.

Why does Undertale’s Papyrus cook spaghetti? 

Papyrus loves to cook spaghetti, but only beady eyed players will know why. It turns out, Papyrus’ reason for cooking the Italian staple is incredibly wholesome – he cooks it because he thinks that everyone loves it. You eventually find out that this isn’t the case, though few characters have the nerve to tell the skeleton they don’t like their spaghetti, but it’s just another reason why Papyrus is one of the low-key sweetest characters in the Underworld.
