Marianna, or Mari for short, is an recurring OC created by Amy the Crying Girl. She's an undead adult woman who has a crush on Grillby. Mari was killed when a fire burned her house.
Mari is a humanoid fire monster that has fire hair that covers one of her yellow eyes. She wears a white shirt, blue shorts, white socks and black doll shoes.
Mari is shy, gentle and kind. She doesn't talk a lot and doesn't talk to anyone but Toriel. She still remembers her past despite being in the underground for a long time. Mari has social phobia (the fear of talking to people), probably because she's a human and the others are monsters.
