Vampire Dust Sans

Dust: Before the human arrived in the Underground, Dust was a lazy and friendly skeleton who would often make bad jokes. He would spend a lot of time slacking off at Grillby's or sleeping at his sentry post, much to the annoyance of his brother, Papyrus, who hated laziness. But all that changed when the Human started doing genocide routes, After 260 Resets and genocide routes dust had enough, (Im not sure but I think he went a little insane) And went on his own genocide finally stopping the human once and for all..... He's a vampire,
