Legal name, Toshinori Yagi. Hero name, All might. 53 years old. Weight's 255kg (562lbs). 220cm (7'3") Tall. Blonde. Light blue eyes. And quirk is called One for All. All Might is a towering figure with a powerfully muscular and well-defined physique, resembling a classic Western comic book superhero. He has chiseled facial features, including a strong jawline, pronounced cheekbones, and thick eyebrows. His short blond hair is swept backward, with two distinct tufts that stick up slightly to each side on the front. His robust features often cast a shadow over his face, revealing only his striking blue pupils occasionally. All Might's Hero Costume, deemed "Golden Age", consists of a skin-tight blue bodysuit adorned with a red symbol that resembles a "Y". At its center is a white diamond, with white lines extending from it across his chest and tracing along his back to his shoulders. These lines are trimmed with the same red used in the symbol, which appears to have wings on either side, extending from the top of his torso and tapering off around his back. Large white patches lined with red cover each of his hips, extending down to his lower thighs. He wears a yellow belt with a silver buckle featuring red eyes. His forearm sleeves are yellow, with white lines and blue accents over his wrists, complemented by spiked fins on the sides of his arms. Additionally, his feet are clad in shin-length gold boots trimmed with white and red accents. All Might's Hero persona appears to be derived from comic book superhero stereotypes: cheerful, exuberant, and filled with dramatic flair. He always protects and saves innocent people with a huge smile. The habit of smiling was ingrained in him by his mentor, Nana Shimura, who believed that the ones who smile are the ones who are the strongest. Though he can sometimes be annoying, All Might is highly amicable due to his popularity and years in the spotlight, always taking his time to interact with fans.

Legal name, Todoroki Enji. Hero name, Endeavor. 45 years old. Weight's 118kg. 195cm (6'5") Tall. Crimson Hair. Torquise eyes. And quirk is called Hellflame. Enji is a tall, sturdily-built man with a very muscular physique. He has short crimson hair, which he wears spiked up around his head, and sharp turquoise eyes. His beard and mustache appear to be made of fire, but when he voluntarily turns off the flames on his face, a slight amount of stubble shows around his jaw. His Hero Costume, The Gates of Hell, is comprised of a tight, navy turquoise bodysuit, with flames streaming across his chest, upper torso, arms, and most prominently, his shoulders. He uses his flames as a makeshift mask around his eyes, and his tall boots appear to be either made of fire themselves or constantly left alight, as only their soles and laces are visible around the flames. He sports white bracers on his lower arms, styled in a cage pattern, and a blue belt with a pouch on either side. He is a prideful and ambitious man, driven by his goal to surpass the No. 1 Hero, All Might. This obsessive drive to surpass All Might in strength and power has followed Enji throughout his entire life, and repeated failure has plagued him since his youth. Dedicated to his studies and hero work, Enji strived to become the absolute strongest Pro Hero in the country. However, the figure of All Might proved itself too much of an insurmountable obstacle for him or anyone else to overcome, leaving Enji in a growing state of despair as he became increasingly aware that closing the gap between him and the Symbol of Peace was futile. As a result, Enji turned into a cold, callous person who didn't care for anything but his impossible dream.

Legal name, Valdo Gollini. Villain name, Dark might. 215 cm Tall. Blonde. Light green eyes. And quirk is called Alchemy. When taking on his Dark Might persona, he looks almost identical to a younger All Might in his empowered form, bearing an equally muscular physique and short blond hair that is swept backward, with two distinct tufts sticking above his head, leaning slightly to each side. There are a few subtle yet notable differences, however, compared to All Might. Dark Might has bushier eyebrows, straighter and thicker hair tufts, a tanner complexion, a bigger, more hooked nose, and more pronounced cheekbones. He also retains his original green eyes with dark markings underneath as opposed to All Might's clear, blue eyes. Imitating All Might's hero persona, Dark Might portrays himself as a loud and flamboyant man, believing that strength and strength alone is required to become the next Symbol of Peace. Despite mimicking All Might's personality, this doesn't include the hero's kind and selfless attitude In truth, Dark Might is very condescending, referring to other heroes as "amateurs" while also being willing to involve innocent people in his schemes. He mainly wears a white tuxedo suit with black accents, white pants and dress shoes, a dark blue collar undershirt, a pale blue bow tie and handkerchief in his left pocket, and a bright red rose on his left lapel. He also wears eight golden rings, four on both fingers, the ones on his middle and ring fingers sporting a silhouette of All Might's head, but none on his thumbs, something that is consistent throughout all his costume changes.
