Swapfell: Red Sans is the more ambitious and serious of the two Skeleton Brothers in the FellSwap Red AU. He thinks Papyrus is a crybaby sometimes. He is an adoptive uncle to Chara. He calls Chara ‘Puppy’ and ‘Angel’ as nicknames. He knows how to cook ravioli really well, and can even make it in different shapes! Such as squares, circles, and even bowties and hearts! He is extremely protective of Chara, and would do anything to keep her safe and happy.
