Mary

Mary is a member of the Avatar cult.

Appearance
Mary is a petite young woman. Her pink hair is cropped short, reaching only up to her shoulders and elegantly framing her dainty face. A thick bang hangs down her temple and between her eyes. The most striking feature about her face is her large eyes. The irises are golden and appear to have diamond-shaped symbols engraved into them in place of pupils. She also paints her nails with black nail polish.

Mary wears a simple dress with a turtleneck. The upper part and the sleeves are black. The sleeves are much longer than her arm and, hence, rolled back into cuffs, revealing the underside to be white. The lower part of the dress is white in color, the two colors clashing at the chest in a jagged pattern. The dress reaches up to her thighs, and the bottom edge of the dress is also black, flaring out like a mini-skirt or frock. A necklace with crescent-shaped links adorns her neck, the pendant laying on her chest. The pendant is a simple light blue stone with a golden frame. She also wears a simple black headband that gives her the appearance of having feline ears.

Personality
Like all other Avatar members, Mary appears to be an ardent follower of Zeref. Aside from this, she is quite childish, calling out others on any lame puns that they make. She is also carefree, treating a serious matter such as a spy in their organization lightheartedly. Her sense of humor is quite morbid and pessimistic, causing Briar to call her "Poison Tongue", much to her fury. She also finds dark things like Gray's thirst for revenge quite cool, further proof of her somewhat skewed mentality.

Avatar arc
At a meeting of Avatar cultists, Mary vows to purify the world for the sake of Zeref, then grins at Gray, another participant of the gathering. Later, when Jerome reports that Arlock refuses to give an immediate decision on how to deal with any interference caused by the Magic Council, Mary jokingly suggests that somebody might actually come for them due to the old man's stubborn attitude and gets angry when Briar scolds her for the macabre joke, stating that Briar's habit of coming up with terrible nicknames for others is worse. Her fury is short-lived as she immediately teases Goumon's word play. When the topic about there being a spy amongst their ranks is brought up, she seems to agree with most that Gray is the likeliest candidate as he is a former Mage of Fairy Tail. When Gray reveals his objective for joining Avatar and his pure lust for revenge against E.N.D., Mary remarks that nobody as dark and evil as Gray could work alongside the Council, also saying that he is quite dreamy.
