Mount Lady (Ｍｔ．レディ) is a Pro Hero in Boku no Hero Academia.

Appearance
Mount Lady is an average woman with long light colored hair styled into two braids falling over her shoulders.

Mount Lady's hero costume is composed of a unitard which is black around her chest, belly and back, and also legs and forearms, and on the rest of her body. There are also white lines that separated the black and white parts, as well as around her neck and shoulders. She also has black gloves with the white lines at the end of the gloves. She has three white diamond shaped dots on the black part of her lower chest. She also wears a black domino mask with horn-like details on the sides.

Personality
Mount Lady is a girl who seems to enjoy the attention that being a hero that gives her but feels bad when having to take that fame from another hero. However, she is not careless, as shown that she won't transform into a giant in confined spaces in fear of destroying nearby buildings, and is careful when fighting a villain who has taken hostages.

Entrance Exam Arc
As Kamui Wood was restraining his opponent with his Lacquered Chains Prison move, Mount Lady suddenly interfered in his fight, attacking the villain with her Canyon Cannon move, and subsequently defeating it. She then introduces herself to the awestruck crowd, proclaiming it to be her first day on the job, and is afterwards greeted by photographers and paparazzi.

When Katsuki Bakugou is taken hostage by a villain, she is unable to do anything due to not having room to move around.

Ultimate Space & Jams Arc
She along with Kamui Wood were having trouble dealing with Vihara Headgear, as he was holding hostages, that was until All Might showed up and had beaten him and saved the hostages. Although she and Kamui Wood were grateful, they complained that he'll put them out of a job.

Sports Festival Arc
Mount Lady is seen outside the Sports Festival, having been assigned to guard security. She comments, while eating snacks, that all the professional heroes came to watch the event and notes that this year "is gonna be crazy".

After the rules of the Human Cavalry Battle are explained, Mount Lady, along with Kamui Wood and another hero discuss competition and cooperation in the Hero business. The other hero says that if a hero fails, they loose any chances of surviving, and notes that the Obstacle Race is a perfect example of how sometimes one has to lower someone else to show themselves off, and Mount Lady mentions that she felt bad for taking out Kamui Wood's enemy on her first day of work, also asking the other hero to stop smoking, while Kamui Wood agrees with the hero. Mount Lady then comments that sometimes heroes have to cooperate with their concorrents, and that the Human Cavalry Battle is a perfect analogy to that.

Quirk
Gigantification - Mount Lady's Quirk allows her to grow to titanic size.
