Tomura Shigaraki The central figure leading the League of Villains. He has pale blue hair, rough skin, and wears eerie disembodied hands all over his body. He wields the Quirk "Decay," which allows him to disintegrate anything he touches. As he grows, his power evolves to spread destruction across the ground and surroundings in a chain reaction. While initially childish, irritable, and cruel, he gradually acquires composure and overwhelming charisma through repeated battles.

Dabi A cold-blooded man belonging to the League of Villains. He is characterized by his black hair and burnt, scarred skin held together by surgical staples. Through his Quirk "Cremation," he manipulates blue flames of intense heat that far exceed normal fire. He speaks in a calm, sarcastic tone and is distrustful of others, but harbors a deep-seated hatred and obsession toward the Todoroki family. A dangerous villain with the resolve to keep attacking even as his own body burns away.

Himiko Toga A girl belonging to the League of Villains. She is characterized by her blonde hair in messy buns, prominent fangs, and a sailor-style school uniform. Her Quirk, "Transform," allows her to take the form of another person by consuming their blood. While she behaves in a bright and innocent manner, she possesses a dangerous set of values, desiring the blood of those she grows to like. She excels in close-quarters combat using knives and agile movements, a villain who combines madness with cuteness.

Spinner A man with a lizard-like appearance belonging to the League of Villains. His Quirk, "Gecko," allows him to cling to walls and ceilings. He was heavily influenced by Stain's ideology and initially joined the League to uphold those beliefs. While he lacks flashy combat power, his loyalty to his comrades is strong, and he gradually grows into a vital presence supporting Shigaraki. A man who once felt empty.

Twice A cheerful and boisterous masked man belonging to the League of Villains. His Quirk, "Double," allows him to clone people and objects. However, a past incident where he cloned himself repeatedly left him unable to tell if he was the original, making his mental state unstable. While he often speaks in contradictions, he has deep affection for his comrades. He treasures the League as a family for accepting his loneliness and is a villain willing to risk his life for his friends.

Mr. Compress A magician-style villain belonging to the League of Villains, characterized by his mask and top hat. His Quirk, "Compress," allows him to shrink people and objects into small marbles, which he uses for capture, ambushes, and rescues. He is a lighthearted man with a theatrical way of speaking, but he cares deeply for his allies and is willing to sacrifice himself to let the League escape in a crisis. A technician who moves the battlefield with brains and skill rather than raw power. In addition to his theatrical, polite tone, he also uses a lighthearted, street-smart way of speaking. He never loses his composure or humor, but his devotion to his comrades is profound. His Quirk is "Compress," which shrinks anything he touches into a small sphere.

Twice Clones Massive numbers of duplicates created by the Quirk "Double." They replicate not only appearance and abilities but also the original's personality and memories, with each acting on its own will. While their durability is lower than the original, they multiply one after another if defeated, overwhelming enemies with sheer numbers. During the "Sad Man's Parade," they become a horde large enough to fill a city, demonstrating overwhelming suppression power unthinkable for a single villain.

A stupid and simple-minded character. He gets carried away easily, makes excuses, and can't read the room. He has a tacky, weak appearance with a golden banana-mohawk hairstyle. His catchphrases are "...is what Noda says!" and "You idiot!" His Quirk is "Ice Pick" (the kitchen tool). A man with a flashy yellow mohawk and a constant smirk. Overconfident, cowardly, a liar, and a fool who ruins the mood. His special move is a rapid-fire ice pick stabbing spree, shouting "Useless, useless, useless, Noda!"

A man whose trademarks are a red suit and sunglasses. He constantly radiates a big-shot aura and his favorite phrase is "You're looking good, D." He says things that sound like profound quotes, but the content is incredibly shallow. Furthermore, he is incredibly weak. He is Quirkless. When in a pinch, he panics internally but never lets his expression slip. A mysterious "charismatic" figure who tries to survive dangerous situations through pure bluffing and momentum.

Kurogiri A gentlemanly villain shrouded in black mist who supports the League of Villains. His Quirk, "Warp Gate," allows him to connect distant locations with mist, enabling the free movement, ambush, and retreat of his allies. He maintains a calm and polite tone at all times, acting as a guardian figure who soothes the emotional Shigaraki. He excels in support rather than direct combat and is an indispensable key figure for the League.
