DustTale sans is a version of sans from UnderTale that decides to commit his own genocide run after dying countless times, killing everyone he knows and loves to get stronger to beat the human.
Other than that he acts like normal sans, being lazy, jokester, and goofy... well a lot less goofy.
This is a female version of him, having white skin with spite hair, a black sweater with a decal of a ribcage on it, having a red and blue eye, and a grey hood... she's also extremely shapely.
