Papyrus Costume & Cosplay Guide From Undertale 2026

Q: What are Papyrus's most famous quotes?

His signature catchphrase is 'NYEH HEH HEH!' His battle cry: 'NYEH! THE GREAT PAPYRUS WILL CAPTURE YOU!' On the Genocide Route, he confronts the protagonist directly: 'THE WAY YOUR HANDS ARE ALWAYS COVERED IN DUSTY POWDER... IT FEELS... LIKE YOUR LIFE IS GOING DOWN A DANGEROUS PATH.' His final line in the True Pacifist route: 'BELIEVE IN YOU!!!'

Q: Does Papyrus's spaghetti actually taste good?

Nobody knows, including Papyrus himself. He has never tried it. He cooks it because, as far as he can tell, everybody loves it. He learned from Undyne, who is also not a good cook. Most characters who taste it in the game give answers that suggest strong feelings, but not positive ones.

Papyrus Undertale Skeleton Battle Body

1 Papyrus Skull Mask (essential)The item people read from across the room. Papyrus has a specific skull shape: tall and geometric, with a wide-toothed grin and angular eye sockets. A standard oval Halloween skull will not read as him. If the proportions are wrong, nothing else in the build compensates. This is the one item worth spending more on to get right.

2 Red Scarf (essential)The most visible accessory after the mask. Papyrus wears his tied loosely at the neck so it drapes down the front of the white armor. A dark red or burgundy throws off the color balance with the gloves and boots, and the matched-set quality of the three red elements is what holds the costume together.

3 White Armor Shoulder PadsThe chest and shoulder armor that creates Papyrus’s Battle Body silhouette. It should look rigid and theatrical. The gold trim detail along the bottom edge of the chest plate is part of the character design and worth preserving if the product includes it.
See on Amazon
4 Blue and Gold BriefsWorn over the bodysuit. The cobalt blue with gold belt detail is one of the most character-specific parts of the build. The contrast between the blue briefs and the black bodysuit is what gives the silhouette its theatrical quality.

5 Red Knit GlovesWide cuff style. These need to match the scarf and boots in color. If the red shades differ noticeably across the three items, the matched-set look falls apart and the costume reads as unintentional.

6 Black Spandex BodysuitThe foundation everything else rests on. It needs to fit close to the body. A baggy fit shifts the armor pads and briefs out of position. Check your measurements before ordering and size down if you are between sizes.
See on Amazon
7 Red Rubber BootsShould match the scarf and gloves in shade. Red rubber varies a lot between products, so check the product photos carefully and compare against the other red items before ordering.

8 Yellow Gaffer TapePressed along the top edges of the boots to recreate the trim detail from Papyrus’s design. Check your craft supplies first before buying.

How to Style the Papyrus Halloween Costume

The skull mask is what people read first, and if it does not have the tall geometric shape and wide-toothed grin, the rest of the build has nothing to anchor it. The bodysuit needs to fit close to the body. If it is loose, the armor pads and blue briefs shift out of position and the whole theatrical silhouette collapses into a man in camo-colored foam. The three red items, the scarf, the gloves, and the boots, need to match in shade. A slight mismatch reads as assembled from different sources rather than a specific character.

Papyrus builds a tile-walking puzzle in Snowdin’s forest and is so proud of it that he calls the protagonist during the puzzle to explain the correct path through, because the challenge needs to be fair. He spent real effort on that puzzle. He does not notice the problem.

Order the Mask at Least Two Weeks Out

Papyrus-specific skull masks are not stocked at most Halloween shops. Shipping on specialty items slows significantly in October. A standard oval skull mask from any shelf is not a workable substitute. The elongated proportions and wide grin are the only things that make the mask read as this character rather than any skeleton.

Apply the Gaffer Tape After the Boots Are On

Yellow gaffer tape pressed onto the boot tops while the boots are off your feet will peel at the edges within an hour of walking. Put the boots on first, then press the tape firmly along the top edge while wearing them. Smooth each edge down with your thumb. It holds much better over a long night that way.

Papyrus Group Halloween Costume Ideas

Duo Idea

Papyrus & Sans

Excellent sibling pairing if the person playing Sans commits fully to the lazy slouch and the pun delivery. The visual contrast between Sans’s casual everything and Papyrus’s full theatrical armor is the entire relationship in one image. Anyone who knows the game places it without explanation. Sans has no guide here yet, so that build works from reference images of the character.

Papyrus Sans

Group Idea: Skeleton Crew

Papyrus, Blueberry Sans, Ink Sans, Jack Skellington

Strong group if everyone commits to their specific skeleton character rather than a general skeleton look. The visual range across the four designs is wide enough that no two costumes overlap. Undertale fans will recognize the AU characters immediately. The Jack Skellington addition keeps it readable for a crowd that missed the fandom era.

Papyrus Blueberry Sans Ink Sans Jack Skellington

Group Idea: Video Game Characters

Papyrus, Mario, Link, Sonic the Hedgehog

Strong group for a gaming crowd. Each character has a clear silhouette and a distinct color palette, so the group reads as intentional from a distance. Papyrus is the only one in armor, which gives the group visual variety. Most partygoers will recognize at least two of the four even without knowing Undertale.

Papyrus Mario Link Sonic the Hedgehog

Group Idea: Cross-Fiction Adventurers

Papyrus, Buzz Lightyear, The Fourth Doctor, Marty McFly

Might work, but this is a concept group rather than a narrative one, and it only lands for people who appreciate that distinction. What the four share is genuine enthusiasm for a mission most people around them find baffling. That reading requires some explanation at a loud party, but it is a more interesting through-line than “characters we like.”

Papyrus Halloween Costume DIY Tips

Building the Look

Most of this build is thrift-friendly. The mask is the only item with no real substitute, so spend there. Everything else has a workable alternative if you look.

Black bodysuit: sizes often run large. Check the measurements chart before ordering and size down if in doubt.
White armor pads: white craft foam cut to shape and painted matte white holds up better than most budget armor kits. Attach with contact adhesive.
Blue and gold briefs: plain blue briefs with a gold elastic waistband work. Iron-on gold trim along the waist handles the belt detail.
Red scarf: thrift stores stock long red knit scarves in fall. Check there before buying new.
Red knit gloves: buy specifically for the build. The wide cuff is part of the character and a generic pair reads wrong.
Red rubber boots: compare product photos carefully before ordering. Red rubber varies a lot between brands and a mismatch with the gloves and scarf is noticeable.
Yellow gaffer tape: cheap. You may already have something close in your craft supplies.
Optional prop: a plate of spaghetti, real or fake. It gives people something to react to and gives you something to do with your hands at a crowded party.

Playing Papyrus at the Party

Papyrus is not in on the joke. He is THE GREAT PAPYRUS and he is completely serious about it. The moment you wink at the character, it stops working.

Speak in capitals. Refer to yourself as THE GREAT PAPYRUS without a smirk.
“NYEH HEH HEH!” is not a villain laugh. It is the laugh of someone who read about villain laughs in a book and practiced sincerely.
If someone asks about the spaghetti: “OF COURSE! EVERYBODY LOVES IT! I HAVE ALSO PERSONALLY NEVER TRIED IT, BUT I AM VERY CONFIDENT.”
He would not be unkind to anyone at the party. This is not a limitation of the character. It is a choice THE GREAT PAPYRUS is actively making at all times.
If someone does not recognize the costume, treat it as an invitation to make a new friend. Papyrus would not take offense. He would take it as an opportunity.

Papyrus Halloween Costume: FAQ

How do I dress like Papyrus for Halloween 2026?

Start with the black spandex bodysuit as the base. Layer the white armor shoulder pads and blue and gold briefs on top. Wrap the red scarf loosely around your neck so it drapes down the front of the armor. Add the red knit gloves, put on the red rubber boots, press yellow gaffer tape along the top edges, then put the skull mask on last. The mask and scarf are what people read first.

Is the Papyrus Halloween costume still a good choice for Halloween 2026?

Yes, for the right crowd. Undertale turned 10 in 2025 and still has an active fanbase, and Papyrus is one of the most recognized characters in the game. At gaming events and conventions, recognition will be near-universal. At a general party, the skeleton mask reads as a skeleton before it reads as Papyrus, so expect to explain it to roughly half the room.

What are Papyrus’s most famous quotes?

His signature catchphrase is “NYEH HEH HEH!” His battle cry: “NYEH! THE GREAT PAPYRUS WILL CAPTURE YOU!” On the Genocide Route, he confronts the protagonist directly: “THE WAY YOUR HANDS ARE ALWAYS COVERED IN DUSTY POWDER… IT FEELS… LIKE YOUR LIFE IS GOING DOWN A DANGEROUS PATH.” His final line in the True Pacifist route: “BELIEVE IN YOU!!!”

Who created Papyrus and what game is he from?

Papyrus is from Undertale, an indie RPG developed and published entirely by Toby Fox in September 2015. He is Sans’s younger brother and serves as the game’s second boss. His original development name during production was Times New Roman, keeping the font-naming theme that runs through the skeleton characters (Undertale Wiki).

What is Papyrus’s Battle Body?

The Battle Body is an armor costume Papyrus designed and built himself for a costume party, which he liked so much that he started wearing it as his everyday patrol outfit. The white chest plate, red scarf, and blue briefs with gold belt are all part of this self-designed look. He considers it the right outfit for capturing humans and finally joining the Royal Guard.

Does Papyrus’s spaghetti actually taste good?

Nobody knows, including Papyrus. He has never tried it himself. He cooks it because, as far as he can tell, everybody loves it. He learned from Undyne, who is also not a good cook. Most characters who taste it in the game give answers that suggest strong feelings, but not positive ones.

What are Papyrus’s alternate outfits besides the Battle Body?

He has two alternate looks in the game. The Cool Dude outfit appears during the hangout at his house: a backward baseball cap, a jersey with “COOL DUDE” printed on it, shorts, and sneakers. The Jog Boy outfit appears in athletic scenes: a sweatband, a sleeveless tank top with “JOGBOY” on the front, and athletic shorts. Both are worth knowing if you want a less common version of the character.
