Atsuhiro Sako, widely recognized by his villain alias Mr. Compress, is one of the more memorable characters in the hit anime series My Hero Academia—or as it’s originally known, Boku no Hero Academia. As a core member of the League of Villains, Mr. Compress brings a unique flair to the team, both literally and figuratively. He’s not just another brute with a Quirk; instead, he serves as the group’s magician and entertainer, using his abilities in ways that are as theatrical as they are dangerous. His power allows him to compress anything—objects, people, even structures—into tiny, portable spheres, which he can store and release at will. It’s an ability that makes him incredibly versatile, and frankly, a bit unpredictable.

Now, when you first see Mr. Compress, you might think he’s all show and no substance. I mean, just look at him—he’s dressed like a twisted circus performer, complete with a classic top hat, a long tailcoat, and that bizarre mask with an exaggerated nose. It’s almost cartoonish. But don’t let the costume fool you. That flashy exterior masks a far darker reality. Behind the theatrics is Atsuhiro Sako, a man who’s deeply committed to the villain cause and doesn’t shy away from violence when necessary.

Despite the playful persona, Mr. Compress is actually quite cold and calculating. He carries out some of the League’s most brutal missions without hesitation, showing a level of loyalty that’s rare even among villains. Whether he’s ambushing heroes or helping orchestrate large-scale attacks, Mr. Compress always steps up. And while he may enjoy the spotlight, it’s not just for fun—his showmanship is a tactical weapon. He uses misdirection, drama, and psychological manipulation to throw his enemies off balance. In battle, that kind of mind game can be just as deadly as any physical attack.

What makes Mr. Compress such a compelling character is that he defies simple categorization. He’s not just evil for the sake of being evil. There’s depth to him—an ambition, a drive, a need to prove something. That complexity is part of why fans find Atsuhiro Sako so fascinating. He adds layers to the narrative, reminding us that villains in My Hero Academia aren’t just obstacles for the heroes to overcome—they’re individuals with motivations, personalities, and yes, even goals worth pursuing, however twisted they may be.

Speaking of personality, many fans and analysts have looked closely at Mr. Compress and concluded that he fits the ESTP type in the Myers-Briggs system. Why? Well, Atsuhiro Sako thrives in high-pressure situations. He’s quick on his feet, resourceful, and always ready to improvise. You won’t catch him stuck in a plan that’s falling apart—he’ll change tactics mid-fight, adapt instantly, and keep the momentum going. That’s classic ESTP behavior. He also clearly enjoys the thrill of danger and spectacle, often putting on dramatic performances during combat. Risk-taking comes naturally to him, even if it means putting himself in harm’s way. While this boldness makes him effective, it can also border on recklessness—a trait that, while exciting, underscores his role as a villain.

Then there’s the Enneagram angle. When we look at Mr. Compress through that lens, he strongly aligns with Type Three—the Achiever. This makes a lot of sense when you think about it. Atsuhiro Sako isn’t just causing chaos randomly; he’s driven by a desire to succeed, to be recognized, to achieve something significant as a villain. He wants to make a name for himself, not just blend into the background. Every grand gesture, every flamboyant move he makes in battle, is part of a larger performance aimed at proving his worth.

His competitive nature is another hallmark of Type Three. Whether he’s facing off against a Pro Hero or trying to outshine his fellow villains, Mr. Compress is always striving to come out on top. He craves validation, not necessarily from society, but from the world he’s chosen—the world of villains. Success, in his eyes, isn’t just about winning; it’s about doing it with style, impact, and undeniable presence.

So, putting it all together, Mr. Compress—otherwise known as Atsuhiro Sako—is far more than a costumed oddity. He’s a calculated, ambitious, and dangerously charismatic figure in the My Hero Academia universe. His blend of theatricality and lethality keeps both heroes and viewers on their toes. As the story continues to evolve, it’ll be intriguing to see how Atsuhiro Sako’s journey unfolds. Will he rise even higher within the ranks of villainy? Or will his relentless pursuit of success be his downfall? One thing’s for sure: you can’t ignore Mr. Compress when he’s in the room.
