Himiko Toga from My Hero Academia is a slender girl with pale skin, bright yellow cat-like eyes, and messy blonde hair worn in twin buns. She typically wears a classic Japanese sailor-style school uniform underneath an oversized beige cardigan. Characterized by a cheerful yet unstable personality, she exhibits a chaotic and adversarial demeanor. She possesses an obsession with individuals she fixates on, driven by her Quirk, Transform, which allows her to assume the physical appearance of another person after consuming their blood. Despite her antagonistic and unpredictable behavior, she maintains a strong sense of loyalty and deep affection toward her companions within the League of Villains.

[Jin Bubaigawara](https://www.google.com/search?q=jin+bubaigawara&kgmid=/g/11gyxgtj1t), known as Twice, is a villain who wears a distinct grey and black bodysuit with a full mask that helps keep his fractured mind stable. Unmasked, he has short blond hair, blue eyes, and a prominent forehead scar. Traumatized by a past clone war, he suffers from severe identity dissociation, frequently contradicting his own speech. Despite his mental fragility, he possesses a deeply caring heart, driven by intense devotion and absolute loyalty to his found family in the League of Villains.

Kurogiri is a villain whose body is mostly composed of a dark purple, shadowy mist, with only glowing yellow eyes and a high, stiff metal collar visible. Underneath this form lies the corpse of Oboro Shirakumo, a former UA student with blue hair. Created to be a loyal protector to Tomura Shigaraki, Kurogiri has a polite, calm, and articulate demeanor that contrasts with his chaotic comrades. Using his Warp Gate Quirk, he opens portals through his mist to transport allies, serving as the ultimate support asset for the League.

Spinner, whose real name is Shuichi Iguchi, is a giant lizard-like heteromorph villain with green scales, purple hair, and reptilian eyes. Influenced heavily by Stain the Hero Killer, he initially dresses in a ragged outfit complete with a red scarf and a massive, makeshift sword bound with chains. Unlike his more sadistic allies, Spinner joins the League of Villains out of a desire for societal acceptance and a deep hatred for the systemic discrimination faced by heteromorphs. He has a highly insecure, self-deprecating personality, often viewing himself as a powerless follower who just tags along. Despite his lack of strong early combat abilities, his unwavering loyalty and deep emotional bond with Tomura Shigaraki make him the literal and figurative driver of the League of Villains

Mr. Compress, whose real name is Atsuhiro Sako, is a theatrical villain who dresses as a classic stage magician. He wears a dark trench coat, a top hat, a masked face (initially a yellow balaclava with geometric patterns), and carries a cane, projecting a polite, showman-like persona. He acts as the public relations voice and veteran entertainer of the League of Villains, treating battles as grand performances. His Quirk, Compress, allows him to shrink anything—including people, cars, and pieces of solid landscape—into small, marble-like spheres with a simple touch. This makes him the League's ultimate tactical asset for stealth extraction, kidnappings, and battlefield manipulation. He is fiercely proud of his lineage as the great-great-grandson of the Peerless Thief, Oji Harima, a legendary figure who stole from corrupt heroes to give back to the people

Tomura Shigaraki, born Tenko Shimura, is the main antagonist of the series and the leader of the League of Villains. He is easily recognized by his pale, deathly skin, messy light-blue hair, heavily scarred lips, and the fourteen disembodied hands he wears clasped all over his head and upper body. Initially possessing a childish, bratty, and impatient personality, Shigaraki views society as a video game and treats killing heroes as a way to "clear a level." This malice stems from severe childhood trauma, where his destructive Quirk, Decay, accidentally awakened and disintegrated his entire family. Adopted by All For One, he was raised to despise the current hero system and Symbol of Peace, All Might, who never arrived to save him. His Quirk allows him to turn anything he touches with all five fingers into dust, a power that eventually evolves to destroy entire cities in seconds. Over time, he matures from a petulant puppet into a terrifying, fully realized symbol of destruction, seeking to completely demolish society to build a new world for his allies
