​Personality: Starts as an immature, short-tempered "man-child" who treats reality like a video game, but evolves into a calm, strategic leader dedicated to destroying hero society to protect his friends. ​Quirk (Decay): Instantly turns anything or anyone he touches into dust. Later, his decay spreads in a chain reaction to anything connected to what he touches.

​Personality: Cold, sarcastic, and completely indifferent to others, driven solely by an intense, destructive hatred for his father, Endeavor. ​Quirk (Blueflame): Generates scorching blue fire far hotter than normal flames, though his body lacks heat resistance and gets burned whenever he uses it.

Personality: Bubbly, playful, and energetic, but holds a twisted view of love where she wants to cut and drink the blood of those she cares about. ​Quirk (Transform): Shape-shifts into anyone whose blood she drinks; drinking more blood keeps her in that form longer, and strong love lets her use their Quirk too.

Personality: Loud, erratic, and humorous, suffering from split personalities and severe self-doubt after accidentally creating clones of himself that tried to kill him. ​Quirk (Double): Creates exact physical duplicates of people or objects using precise measurements, though the clones dissolve into mud if they take enough damage.

Personality: Flamboyant, theatrical, and polite, behaving like a magician who loves dramatic reveals and values team loyalty above all else. ​Quirk (Compress): Shrinks anything or anyone into tiny, weightless marbles by touching them, instantly restoring them to normal size whenever he snaps his fingers.

​Personality: Insecure and hesitant at first, but deeply loyal to Stain’s anti-hero ideals and Shigaraki; he becomes a passionate advocate for mutant-type outcasts. ​Quirk (Gecko): Gives him the physical appearance and traits of a lizard, allowing him to stick to walls and scale steep surfaces easily.

​Personality: Confident, caring, and protective toward her allies, fiercely valuing her personal freedom and refusing to let anyone rule over her. ​Quirk (Magnetism): Magnetizes people within a 4.5-meter radius, assigning men a north magnetic pole and women a south magnetic pole so they either attract or repel each other.
