Overview
Mr. Compress, whose real name is Atsuhiro Sako, is a character from the manga and anime series My Hero Academia. Acting as a core member of the League of Villains, he refers to himself as an entertainer. Dressed in a theatrical ensemble featuring a long robe, mask, and top hat, he approaches villainous operations as grand magic performances. He comes from a lineage connected to the historic thief Oji Harima, carrying on a flair for showmanship and high-stakes escapes.
Appearance
He features short black hair and black eyes. His clothing includes a white shirt paired with a black vest, a bolo tie, and a brooch, along with gloves that appear in red or white. He wears a distinct mask covering his face, a top hat, and a long coat or robe. After losing his left arm in an encounter with Overhaul, he utilizes a prosthetic replacement.
Personality
He maintains a polite, theatrical demeanor, treating every conflict as an elaborate magic act. As a self-proclaimed entertainer, he prioritizes style, dramatic tension, and deception. Despite his criminal alignment, he harbors strong loyalty toward his allies in the League of Villains, willing to risk extreme personal harm for their survival.
Abilities
His Quirk, Compress, allows him to shrink anything he touches—including people, heavy objects, or sections of his own body—into small marble-like spheres. Decompressing them instantly restores the targets to their original state. He combines this power with high agility and sleight of hand to perform quick kidnappings, evasions, and deceptive maneuvers.
Background
Descended from the legendary thief Oji Harima, Atsuhiro Sako joined the League of Villains to carry on his lineage's dramatic ideals. He took part in major operations, including the Vanguard Action Squad's raid on the Forest Training Camp where he captured Katsuki Bakugo. After losing his left arm during a clash with Overhaul, he remained dedicated to Tomura Shigaraki's cause through the group's evolution into the Paranormal Liberation Front, culminating in a desperate escape effort during the Paranormal Liberation War.
Relationships
He shows deep loyalty toward Tomura Shigaraki and shares strong camaraderie with fellow League members such as Dabi, Himiko Toga, Twice, and Spinner. He holds a strong grudge against Overhaul for taking his arm, while revering his ancestor Oji Harima as the ultimate inspiration for his showman values.
Trivia
His real name contains kanji characters associated with pressure and compression, referencing his Quirk. His theatrical motif, mask variations, and escape-artist tactics pay homage to classic phantom thieves and stage magicians.
