Atsuhiro Sako

, also known as , is a recurring villain affiliated with the League of Villains, was a member of the organization's Vanguard Action Squad, and later became one of the nine lieutenants of the Paranormal Liberation Front.
He followed in the footsteps of the Peerless Thief, who was his great great grandfather and became a nationwide wanted thief, being one of the more 'experienced' members of the League. He and the rest of his team serve as the main antagonists of the Forest Training Camp Arc and Paranormal Liberation War Arc. He was arrested after his defeat during the Paranormal Liberation War.
==Appearance==
Atsuhiro is a tall, slim man with pale skin and brown eyes that are semicircular and slightly slanted inwards, and he has a notably pointed nose. He wears a combination of a mask, balaclava, and a hat. Underneath his mask reveals that he has short black eyebrows and a head of curly brown hair, similar in shade to his eyes.
In his villain attire, he wears a dark orange shirt with the collar left upturned, a green striped bolo necktie with an oval-shaped azure brooch hanging around his neck, a black waistcoat, and black dress pants. He wears knee-high white boots with wedged heels and black toe-caps, plain dark red gloves, a tall brown top hat, a red ribbon tied around it, and a pale feather sticking out on the left.
Over his head, he wears a black balaclava with a hole for his mouth as well as his eyes, over which he wears one of the multiple white masks he owns, each with a different black geometric design. In his first appearance, he also wears a dark yellow, double-breasted overcoat with buttoned shoulder tabs and a high collar, which reaches below his knees, and he additionally carries a silver walking stick with a gold handle.
After Overhaul destroys his left arm, Giran gives him a replacement prosthetic which he wears from then on.
During the Paranormal Liberation War, Atsuhiro uses his Quirk on his lower back in an attempt to escape Best Jeanist, thus permanently maiming himself.

==Personality==
Atsuhiro is a showman who likes to command every event he's a part of and be as flashy and entertaining as possible. He is talkative, humorous, and arrogant with his allies and enemies.
Attsuhiro has a habit of monologuing and showing off his entertainer skills. This showboating has proven to be a flaw in his skills as a villain; he allowed the Bakugo Escort Squad to catch him because he spent so much time taunting them. Mr. Compress also nearly lost possession of Katsuki Bakugo after taking a moment to bow after his victory.
Atsuhiro is often the voice of reason among the League of Villains and appears to care for his comrades; he mentors the younger members and frequently keeps them in check. After Magne's death, he immediately leaps into action and tries to subdue Overhaul himself. This action costs him his arm, but Compress quickly gets revenge by destroying Overhaul's arm later.
Though little of his past or motives were shown, it's revealed that Atsuhiro is the great-great-grandson of Oji Harima, who stole from wealthy heroes and gave that wealth to the people. Atsuhiro joined the League of Villains to fight against such a corrupt system and wealthy heroes, exposing the perceived injustices of a heroic society.
==Abilities==
Overall Abilities: Atsuhiro is a competent and resourceful villain with incredible stealth abilities, speed, agility, and proficiency with his Compress Quirk. It is primarily useful when it comes to setting traps. If Atsuhiro has marbles containing particular compressed objects, he can use those to obstruct the path of enemies by throwing them in his adversaries' direction and returning them to their original size. Thanks to Atsuhiro's creativity and ingenuity, he can take advantage of the deactivation property of his Quirk to affect the environment around him, like placing a marble holding a compressed large rock below a car and then launching the vehicle into mid-air through the marble's decompression process. In another offensive manner, Atsuhiro uses his Quirk to selectively compress only one part of a person's body, severely maiming or, sometimes, killing them. Compress also works as a way to dig through solid objects, making Atsuhiro pivotal for escaping and infiltrating enclosed areas. Using Compress on himself allows Atsuhiro to be carried anywhere, undetected. He often uses his Quirk to capture people within compressed marbles without being noticed and before the victim can alert nearby allies.
During the Vanguard Action Squad Invasion, Atsuhiro demonstrated his espionage efficacy by using his Quirk, which requires physical contact, on Katsuki and Fumikage Tokoyami while the pair were in a group of 5 people, which included Mezo Shoji, whose Dupli-Arms Quirk grants the latter enhanced senses. Overall, Atsuhiro single-handedly captured the former two students before their classmates noticed and was only caught when the masked villain made his presence known. Succeeding in the Vanguard Action Squad's mission and making his escape, Atsuhiro easily outpaced the U.A. pursuers in The Beast's Forest by jumping across the treetops and even evading Shoto Todoroki's multiple employments of his "Heaven-Piercing Ice Wall" technique. While he eluded the trailing students, Atsuhiro was surprised when Mezo, Shoto, and a battle-worn Izuku Midoriya crashed him into the ground. In the course of the Kamino Incident, Atsuhiro, along with Himiko Toga and Twice, forced Katsuki on the defensive before his classmates rescued him. With Magne's help, Atsuhiro was nearly successful at recapturing Katsuki, only to be intercepted by Mt. Lady, who knocked out the airborne villain.
When the League of Villains encountered Overhaul, who had killed Magne during the exchange, Atsuhiro was fast enough to catch him off-guard and attempted to capture the yakuza leader. Unfortunately, the hat-wearer's efforts were wasted because he was struck by an experimental Quirk-Destroying Bullet, temporarily erasing Atsuhiro's Quirk, and leading to his left arm being destroyed by Overhaul. Much later, Atsuhiro incapacitated Snatch by circling and touching the sand hero, while the latter was fighting Dabi. By compressing the flame-engulfed Pro Hero, the two villains effectively defeated and killed Snatch. At the Revival Celebration, Atsuhiro faced various members of the Meta Liberation Army but began to struggle until he was saved by Twice's "Sad Man's Parade" technique. After battling the M.L.A., Atsuhiro became a lieutenant of the now-unified Paranormal Liberation Front.
In the climax of the Paranormal Liberation War, Atsuhiro was forced to maim his hindquarter to escape from Best Jeanist's fiber bindings before proceeding to briskly free Tomura Shigaraki, Spinner, and Skeptic from their restraints as well. As he did so, Atsuhiro destroyed more of his body, as Best Jeanist manipulated his clothes to avoid being restrained again. Successful at releasing his bonded allies and securing Dabi, Atsuhiro admitted his efforts were his last and was ultimately defeated by Mirio Togata.
*Enhanced Agility: Atsuhiro possesses an above-average agility. Astuhiro primarily displayed the ability to shift from one motion to another, effectively dodge attacks, and rapidly leap across high ledges and through forest canopies, all while performing other numerous athletic feats with minimal effort. His most notable forms of legerity stem from his Quirk application, being able to swiftly compress targets into small marble-like objects without the opposition's knowledge. At the Paranormal Liberation War's climax, Atsuhiro swiftly bounded across the gargantuan Gigantomachia's back spikes to reach a constrained Skeptic.
Keen Intellect: Atsuhiro is an ingenious villain who thrives in a supporting role. He can act as the brains of an operation and operate efficiently. Being a former stage magician, Atsuhiro is a self-proclaimed master of deception, escapology, and illusion. True to his words, Atsuhiro employs many creative tactics combined with his Compress Quirk to mislead his opponents. A vital example of this misdirection is when he compresses a target into marble form and prepares to be relieved of it by his opponents. Exceptionally cautious with his captives, Atsuhiro utilizes his illusionist skills to clandestinely create decoy marbles and swap them around with the ones holding the actual targets, thus deceiving anybody who attempts to steal from him. Atsuhiro also has good judgment, as he knows the limits of his abilities and can gauge the level of strength another person possesses after seeing them in action once. He decided against fighting hero candidates from U.A. High School, so he instead made a hasty retreat.
When the Bakugo Escort Squad caught up to him and seemed successful at reclaiming the captured Katsuki and Fumikage, Atsuhiro flawlessly tricked his pursuers into thinking the marbles in his pockets were the ones housing Katsuki and Fumikage. Those were decoys containing ice he had discreetly compressed while dodging Shoto’s cryokinetic assault, and Atsuhiro kept the original marbles in his mouth. Once the Hideout Raid Team appeared at the villains' bar, Atsuhiro realized that the televised press conference was being used as a ruse for the team of heroes to get the drop on the League of Villains. During the Revival Celebration, Atsuhiro refuted Twice's attempted cloning of him and Dabi, pointing out that if all of the M.L.A members and Deika City are destroyed, then the League of Villains won't have the fodder necessary to hold off Gigantomachia once the behemoth arrives in the metropolis. When the Paranormal Liberation War approached its end, Atsuhiro took notice of the Near High-Ends in the distance and deduced Tomura could relay orders to the Nomu upon regaining consciousness. But due to Tomura fading in and out of consciousness, Atsuhiro had to get him adequately roused so the body-enhanced villain could effectively command the Nomus.
*Escape Artistry: Atsuhiro is an escape artist whose family has trained to deduct the necessary means for escape. This escapology can be seen by how he recognized and devised multiple ways to escape using his Quirk: compressing himself from under his opponent, using misdirection, digging safely from underground to the surface, or concocting methods for him and his allies to escape from constraints.
===Quirk===
: Atsuhiro's Quirk allows him to "compress" anything in a spherical area around his arm into a small, marble-like object without damaging it. He can only compress his target if he is touching it.
The target's weight is reduced alongside them, making them very easy to carry. If used on a person, it entraps them effectively, terminating the fight instantly and allowing Mr. Compress to abduct them easily.
The Quirk can also be used on select body parts, quickly and efficiently maiming the target. It is implied that mutilating a body part through Compress is painless, as Atsuhiro used it to remove one of Kai Chisaki’s arms as well as maim his own lower body; neither of them seemed to be in deep pain during the process.
He can also use his Quirk to compress himself into a marble, as seen during the Vanguard Action Squad Invasion.
Atsuhiro's Quirk Factor lies within his arms, and after losing his left arm to Overhaul, Compress' activation is now limited to Atsuhiro's right arm.
===Stats===
==Equipment==
Prosthetic Arm: After losing his left arm to Overhaul, Atsuhiro wears a functional robotic arm as a replacement that was provided by Giran. It eventually began to succumb to wear and tear and its hand was broken off after being flung away by Gigantomachia. After becoming a Paranormal Liberation Front lieutenant, he received a replacement prosthetic that enables him to shoot out his marbles from his fingers.
