Mt. Lady

Yu Takeyama (岳たけ山やま優ゆう Takeyama Yū?),[6] also known as the Peak Hero: Mt. Lady (山さん岳がくヒーロー Mt.マウントレディ Sangaku Hīrō Maunto Redi?), is the current No. 3 Hero,[7] a former No. 23 Pro Hero, and member of The Lurkers.Yu is an above-average height young woman of fair skin and curvaceous frame. She has magenta eyes with white pupils and long eyelashes. She has voluminous, creamy blonde hair reaching down to her waist, with two shorter strands tightly curled to frame her face, parted slightly to her right.

Her first costume is composed of a purple and pale tan-colored skin-tight bodysuit, which is accented with orange stripes. The suit appears to have a pair of purple gloves with orange accents on the edge of the cuff. The design is similar for her "boots" which are cut off at the thigh in a deep v-shape. The suit also has three peculiar orange diamond-shaped dots on the purple top that are located under her chest, and she also wears a purple domino mask with horn-like protrusions on the sides.

Following the aftermath of the Paranormal Liberation War, Yu now has a scar over her left eye and a neck brace, but prior the Final War, the neck brace is removed.

Eight years after the Final War, Yu has grown noticeably more mature facial features, became athletically toned in build, and her scar is gone. Her hair is also fuller and wavier, and her bangs are no longer curled like they used to be.

Her latest hero costume sports a drastically different design on her bodysuit, with tan being the more dominant color over purple. The three diamond-shaped marks were relocated to the top of her chest instead of below and are now much larger and colored purple. Her "boots" now have a longer inverted v-shape, and meet to the sides of her stomach. Her "gloves" follow the same design philosophy, completely enveloping her arms, and meeting down the sides of her chest and her neck to form a collared pattern. Additionally, the horns on her domino mask now curve backward, and the bottom portion of the eyeholes have a small spike sticking outward, with it somewhat resembling Midnight's mask.Yu is an ambitious and egotistical woman who enjoys the attention that being a hero gives her and doesn't feel any shame over taking that fame from another hero while basking in the glory. She is shown to be quite vain as she uses her ample sex appeal to further her popularity. This vanity also extends to shamelessness, as she isn't above making a lewd pun about her body or using her attractiveness to gain something. Yu has a fierce temperament, along with a propensity for pushing people's buttons, as she didn't hesitate to poke fun at Midnight during a talk show interview, something that led to a physical fight between the two while they were on air. She also appears to be very lazy, as during Minoru Mineta's internship, she forced him to do menial work instead of actually training him.[8] She is shown to have a lecherous side as well, as seen when she takes an interest in Shoto Todoroki.[9] Overall, while Yu means well as a hero, she is heavily drawn to achieving and indulging in her popularity, doing very little to hide her greed and love of fame.

However, she is not careless, as she will not transform into her giant form in confined spaces in fear of destroying nearby buildings and risk harming civilians. She was also careful when facing a villain who had taken a family hostage. Despite her vanity, she has shown to be brave and selfless when the occasion calls for it, as she stopped Mr. Compress from reaching Izuku Midoriya's group after they saved Katsuki Bakugo, even though she was already severely injured from All For One's attack.[10] She also protected a group of civilians from All Might's Detroit Smash shock wave during her debut. This shows that, despite her faults, she is serious about being a hero and does take her job seriously.

Following All Might's retirement and Endeavor taking stand as the new No. 1 hero, Yu appears to have taken a more serious standing to her job as a hero rather than just being focused on the attention she receives, as noted by Minoru. Shota Aizawa claims that this is the effect Endeavor's uprising has had on many Pro Heroes. Yu herself even tells Class 1-A that people have had enough of the celebrity aspect of heroes and wish to see them do their jobs in earnest. Furthermore, unlike her comrade Death Arms, she didn't quit after the Paranormal Liberation War in spite of the rising hatred against heroes, assisting in the operation to track down All For One and demonstrating her commitment.

Abilities Immense Strength: Yu possesses incredible strength befitting her giant form. She's powerful enough to knock out another giant villain with one kick to the jaw, and during the Kamino Incident was able to destroy the front of All For One's Nomu factory with one axe kick. During the events of the Paranormal Liberation War, Yu displayed the ability to compete with Geten in battle, and later was capable of slowing down Gigantomachia, even forcing his mouth open. In the Final War, with the aid of Rule enlarging support items, Yu fought alongside Fumikage Tokoyami and Gigantomachia to hold back the rewinding All For One.

Immense Durability: Yu's durability is similarly augmented to her strength. She was able to survive All For One's Air Cannon attack, however it knocked her out for a time. She did display enough tolerance after the fact to utilize her Quirk to protect the U.A. students from the League of Villains. During the raid of the Gunga Mountain Villa, Yu went up against Geten and was able to shrug off one of his attacks before engaging him. Later in the battle, she survived attacks from Gigantomachia, albeit with heavy injury. In the Final War, she once again withstood being attacked by Machia, but was able to keep moving and even survive an Air Cannon from All For One without going down.

Seduction: Yu is a prominent user of the seductive arts, using her looks to get what she wants. This was shown when she convinced a stand vender at the U.A. Sports Festival to give her free food.

Keen Intellect: Despite not being shown using any strategy in combat, Yu still proved that she is a hero that can grasp the context quickly. She can observe and understand what plan her allies are having, and provide any possible support at critical moments without being told beforehand, such as when she protected Izuku's group as mentioned above, or when she tried to pry Gigantomachia's mouth to help the U.A. High School students put the sedative into his mouth.[11]
