"what are you doing--"
"NYEHEH... I GOTTA PROTECT MY BROTHER!!"

An old sketch I found and decided to clean up. The idea of Papyrus jumping in front of an attack to protect Sans, his 1HP brother, is just... too much for me..
I see a lot of Sans being protective of Papyrus, but in the game a lot of Papyrus' phone calls are about how he has to look after Sans, and I want to see more of that, I guess...!
