"Additionally, Papyrus's theme song and battle theme were from an earlier RPG idea i was working on for a couple weeks before I gave up." - Toby Fox, talking about what came to be DELTARUNE in the offical Undertale: Art book - which essentially means Bonetrousle was a beta battle theme for Deltarune, which ended up today as Rude Buster. Thats why I ended up using Rude Buster leitmotifs.
 
 (There's also quite a lot of similarities, such as both songs coming from different sources (EBHH and DELTARUNE), having no leitmotifs from their respective games and also appearing in Nintendo Direct.)

Like the Flavor text says, his stats are actually 1 TO 1 with his coded ones, he's stronger than both NEO and Alpha even if the screen doesn't make it seem so.
This is essentially just a boss rush of an "upgraded" version of ~~Popcornpr1nce's~~ Hatsune Miku's UNDERSWAP.

* Oh...!
* You're a human...
* Ho ho ho... 
* Apologies.
* I haven't seen a child like you in a very long time.
* Looks like this old monster is losing his sight after all...
* ...The doors are opening already?
* ...Ah.
* Come with me, child.
* It isn't safe for you here.

Rise, Child

What if Sans's battle theme used the "genocide motif" from BAaTH and Power of NEO
