The last version of Cannibal!Sans here on scratch sucked, so here is an updated version with some facts; Cannibal! eats monsters in general, not just skeletons. He uses DT as a way to preserve monster flesh without it dusting, said DT basically evolved his body to more easily catch prey. Cannibal! hates what he's doing, but cant beat the addiction. He runs mostly on impulse, but has restrained himself from killing the people closest to him, like Papyrus. Cannibal! has been hiding out at the dog shrine. Everyone but Papyrus believes that Sans was eaten by the mysterious Cannibal. I will answer some other questions y'all might ask in the comments
