Mary Anta on a ghost's lawn
In Mary's primary design, she has red hair in a swoopy and fluffy bob taking the shape of horns at the top of her head, as well as spiky bangs. She has large eyes in a brighter red than her hair. Her outfit consists of a small thigh-length long-sleeved black dress with a round white collar and white cuffs at the sleeves and knee-high white stockings with black Mary Janes.
In Tricks N Treats, Mary wears a Halloween costume resembling a zombie bride. It consists of a long, layered light gray wedding dress, the first layer ripped. Splatters resembling blood litter the dress and a large ripped grayish-blue bow is tied at her waist. The dress has a thin strap at the neck, presumably a halterneck, and a silver-lined red heart charm is placed at the center. She also wears a ripped gray veil with black and gray flowers adorning the top, and she holds an upside-down wilting bouquet of flowers.
In Here for Sweethearts, Mary's hair is generally the same, the only difference being that it's much longer and reaches past her waist. Her outfit consists of a laced white button-up shirt, a dark gray cardigan, and a dark purple plaid pleated skirt. Her accessories include a black headband, a ribbon in the colors of the bisexual flag, and bracelets on both her wrists in the colors of the bisexual and asexual flags.
In Blackout Hospital, Mary's face is shaded out, her right eye outlined in neon pink, and a white eyepatch on her left. Her outfit consists of a cyan short-sleeved hospital gown and pink striped socks with yellow slippers in a happy face design. She has a white wristband on her right wrist and a string on her left hand which is connected to an IV on a stand she carries around with her. The IV bag itself looks tie-dye, it has a graphic of a happy face leaking from the mouth on the front.
