Mae is Createsans's Underworld persona.
After all that's happened to her, she's forgotten proper speech, and speaks like a 2 year old. She is childish and quirky, but is also bloodthirsty. As revealed in her battle during Genocide, she still remembers what happened to all the monsters and how to speak properly. She is twisted and insane if Papyrus is killed.
She has white bones and no hair. She has a large crack "scar" over her left eye socket, and her pupils are white circles. She's missing her entire right arm. She has razor sharp teeth. Her fingers levitate over her actual hand.
She wears a white hoodie, which is stained dark red with blood, black torn shorts and red boots. She often wields an immense double-sided axe.
