Theory: Papyrus's battle body
So, everyone should know about 'Papyrus's battle body', it's something I've been pointing aggressively at for years to point out that his brother is a liar-
Contradicting what he says, during the hang out, Papyrus specifies that he wears his special clothes underneath his 'REGULAR CLOTHES'.
Then the interview came out and it turns out I was wrong.. Papyrus's battle body is indeed....
...
....HANG ON A SECOND.
What the interview confirms is that Papyrus does indeed have a battle body, but what's also been confirmed is that it's not his clothes. But there's also an important question to factor in: Does what his brother say, have any merit? Was this 'battle body' made a few weeks ago for a party?
I've mentioned this before but it's very important for this theory, there's a post on the Undertale tumblr that relates to this:
"not everyone is as tough as my brother." - immediately starts talking about Shyren for some reason. "they say those without blame should cast the first stone." (Is this implying something happened to Papyrus that someone could be blamed for?)
Anyway, Shyren's form in battle is made of 2 different monsters, the body is 'Shyren's agent'.
Papyrus loses his head when killed, and his body dusts, then his head. They both have different dust patterns.
"Papyrus's body and head have different dust patterns because it's his battle body but not his battle head" - @fluo-skeletons
If I can make an assumption from the Undertale changelog, dust patterns are changed for each individual monster. There was some extensive research done before I found this, including checking dust pattern related to monster size, HP, EXP, G, and none of them seemed to line up.. Was this patch note intentional for these connections to be made?

What I'm saying is that Papyrus's entire body was made, and he didn't always look how we see him in the game. But this leads to one of the biggest mysteries of Papyrus, what or who is he?
There's not a character that's canonically been shattered to pieces that speaks just like he does, there is never any implication he can read wingdings either so ignore that
He can walk/run through the air, he acknowledges things that implies he knows he's in a game, and how games themselves function. He's implied the ability to use a save file, he can use blasters, his bedroom is silent. It's implied he's been inside the true lab, or at least Alphys's lab. He's implied that he can see from your perspective (NOT FRISK'S, YOURS.), the annoying dog annoys him the most, he can change game UI and take over the whole screen.
Who else has done that?
What other character appears with only a head? Gaster. Papyrus's head is on Gaster's body.
Although it’s not like we can test whether this head would have the same dusting pattern as Papyrus’s body…
