Mount Lady (Ｍｔ．レディ) is a Pro Hero.

Appearance
Mount Lady is a very attractive woman with a voluptuous figure. She has long voluminous blonde hair with two curled strands, and violet colored eyes with white pupils.

Her hero costume is composed of a purple and nude colored skintight bodysuit, that is accented with orange stripes separating the purple and nude. Her bodysuit distinctively imitates the illusion of her wearing nothing but a top, gloves and thigh high boots. The bodysuit also has three peculiar orange diamond shaped dots on the purple top and it's under her chest. She also wears a purple domino mask with horn-like protrusions on the sides.

Personality
Mount Lady is a young woman who seems to enjoy the attention that being a hero that gives her and she doesn't feel any remorse from having to take that fame from another hero while basking in the glory. However, she is not careless, as shown that she won't transform into her giant form in confined spaces in fear of destroying nearby buildings and she's careful when fighting a villain who has taken hostages.

Entrance Exam Arc
As Kamui Wood was about to restrain 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.

Later on the same day, when Katsuki Bakugou is taken hostage by a villain, she is unable to do anything due to not having room to move around.

Unforeseen Simulation Joint 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 takoyaki, 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 Desutegoro 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 concurrents, and that the Human Cavalry Battle is a perfect analogy to that.

Hideout Raid Arc
Mount Lady joins the Police Force and many Pro Heroes in the rescue operation of Katsuki Bakugou.

At the League of Villains' warehouse, Mount Lady destroys the front of the warehouse. Mount Lady along with Tiger, Best Jeanist and Gang infiltrate the partially destroyed warehouse and apprehend all the Noumus while Tiger rescues Ragdoll. Best Jeanist informs Naomasa that the warehouse has been cleared.

A mysterious man appears in the shadows; Mount Lady sees that Best Jeanist is preparing to attack and warns him that the man could be a civilian. Before the Pro Heroes can act, the entire warehouse is destroyed.
