The Multiverse (Undertale AU story) ((MORE ROLES WERE ADDED!))
Underfell Papyrus for Underswap Papyrus (Swap)
Swap is probably my favorite character to write for, and ya gotta get his voice just right to make it work. You gotta be able to argue, with feeling! Intimidation isn't something he uses often, but when he does HO BOY does it work! You need to be able to pull that off, as well as weak and stammer-y speech, like every letter is a huge effort. My head canon for him is The Christmas Party AU voice by YouTube's Starbot Dubs. If you don't like cussing, this character probably isn't for you.
*Very angry* You can't do that! You don't own him, you sick jerk!
*Warning, semi-intimidating* Heh, listen, buddy; If Red is hurt, and I go after him with Sans, we wouldn't stand a chance. Sans and I have 2 HP between us. Not much for protecting someone, ya know?
*Weak, quiet, stammering with effort* hey bro... heh.... guess I'm being lazy again, huh? But... Sans, just this once... Could you... let me rest...?
