Mary Hughes (マリ ヒューズ, Mari Hyūzu) is the Earth Land counterpart of Hughes, who uses Command Magic as her form of Magic.

Mary Hughes appears like her Edolas counterpart Hughes, only with a feminine façade. She has shoulder-length purple hair, save for a wide streak of white hair that runs across the left side of her face. She has yellow eyes and thin eyebrows styled into the shape of arrows.

Mary Hughes wears a dark green full-body suit, which is sleeveless. Under the top of this suit she has a white collared shirt, through which she ties a red ribbon. Around her waist sits a brown utility belt. Her hands are covered with long gloves that end just before her elbow and her feet are covered by large brown boots.

Mary Hughes has a slightly malicious and cruel personality, laughing at the Fairy Tail guild when she saw the pain they were in when they couldn't win against her. She seems to have a liking of controlling people, manipulating them with her Magic and enjoying the fact that she can make them attack their own friends.

She doesn't like people commenting on her appearance, seen when she stated to instantly dislike Natsu when he commented on the fact that she was a woman. When Kinana threw rocks at her, Mary Hughes claimed she was angry enough to commit murder, hinting that she does not like being made to look weak.

When asked by Lucy why she would allow her and Michelle to fall over a cliff, Mary Hughes nonchalantly states that if they fall, they will be injured enough that they won't be able to escape her, showing a total lack of caring for others that she considers her enemy or target.

Later on, near the end of the Key of the Starry Heavens arc, Mary Hughes decided that she was tired of always being used by people, stating that all she's ever been is a puppet. She was being used to achieve someone else's goals, along with the rest of the Legion Platoon, and essentially turned a new leaf. She showed it by helping Lucy to find out the truth about her so-called cousin, Michelle Lobster. In the end, Mary Hughes, along with the rest of the Legion Platoon, was assigned to tracking down the rest of the clock pieces, which was said to be their final mission, since it could take a lifetime to accomplish.
