You’ve probably seen him. He’s the guy who looks exactly like a front-loading laundry appliance, complete with a bubbly personality and a head tucked inside a literal washing machine. In the world of My Hero Academia, where people have powers ranging from creating nuclear-level explosions to literally rewriting the laws of physics, a hero based on laundry seems like a joke. But here’s the thing: Wash is actually a Top 10 Pro Hero in Japan. That’s not a typo.
Kohei Horikoshi, the creator of the series, has a knack for making the absurd feel grounded. While most fans focus on Deku’s struggle or Bakugo’s temper, Wash represents the "utility" side of hero society that often goes unnoticed. He isn't just a mascot. He is a legitimate powerhouse who climbed the Billboard Chart through sheer public adoration and rescue efficiency. He ranks #8, sitting right there among legends like Hawks and Endeavor. It’s weird. It’s brilliant.
The Identity of Susugu Mitarai: More Than Just Bubbles
The man behind the machine is named Susugu Mitarai. Honestly, his name is a pun itself, as "Mitarai" relates to washing or font-cleansing in Japanese. Most people just call him the Laundry Hero: Wash. He first appeared during the Hero Billboard Chart JP announcement in Chapter 184, and he immediately stood out because, well, he’s a washing machine.
His Quirk is officially called Clean Bubbler.
It’s exactly what it sounds like. He generates massive amounts of soapy water and bubbles from his body. Now, you might think, "Okay, he cleans stuff?" Sure. But in a disaster scenario? That’s gold. Think about a building collapse. Dust everywhere, people suffocating. Wash rolls in and uses those bubbles to suppress smoke, cushion falls, and literally scrub the environment clean of toxins.
The mechanics of Clean Bubbler are actually pretty versatile. He can create bubbles strong enough to lift people and move them to safety. This is called "Wash’s Capsule." During the Paranormal Liberation War arc, we saw just how vital this support role is. While the heavy hitters are punching holes in mountains, Wash is the one ensuring the civilian casualty count stays as low as possible. He provides a non-lethal, high-utility service that makes him a PR dream for the Hero Public Safety Commission.
Why Wash is Actually Ranked #8 (And Why it Makes Sense)
It’s easy to dismiss him as a gag character. We’ve seen plenty of those in manga history. But rankings in MHA aren't just about raw power; they are based on resolved incidents, contribution to society, and approval ratings. Wash is basically the most "merchandise-friendly" hero in existence.
He speaks in one-word sentences. "Wash!" That’s basically it. He’s like a Pokémon. This makes him incredibly popular with kids. In a world where the #1 hero (Endeavor) was a terrifying, flame-shrouded man with a history of domestic issues, Wash is the "palate cleanser." He’s safe. He’s cute. He’s effective.
The Rescue Statistics Factor
If you look at the stats provided in the Ultra Analysis book, Wash has a high "Rescue" and "Social" rating.
- He’s a specialist in water-based rescue.
- His Quirk allows for crowd control without causing permanent injury.
- He manages a massive agency that specializes in disaster cleanup.
In the aftermath of a villain attack, the city doesn't just need the villain in jail; it needs the streets cleaned of debris and chemicals. That’s where the Laundry Hero: Wash excels. He’s the bridge between combat and reconstruction. He represents the "Save to Win" philosophy just as much as Deku does, just through a much more domestic lens.
Wash in the Paranormal Liberation War: Not a Joke Anymore
When the war against Shigaraki’s forces broke out, Wash was part of the Villa Backup Team. This wasn't a PR stunt. He was on the front lines at the Gunga Mountain Villa.
Think about the chaos of that battle. Thousands of villains, massive structural damage, and fire everywhere. Wash’s ability to generate endless amounts of pressurized water and bubbles was a tactical necessity. He worked alongside heroes like Fat Gum and Fourth Kind, proving he can hold his own when the stakes are life and death. He wasn't just standing there looking like an appliance; he was actively mitigating the damage from high-level quirks.
There’s a specific nuance to his power that often gets overlooked. The bubbles he creates aren't just fragile soap suds. They have a certain degree of surface tension that allows them to act as physical barriers or transport vessels. In the manga, we see him using these to move injured heroes away from the blast zones. It’s high-speed triage.
The "Laundry Hero" Design: A Masterclass in Character Branding
Horikoshi is a fan of Western comics, and you can see that influence in how he designs heroes. But Wash is uniquely Japanese. He looks like a "Yuru-chara" (those quirky regional mascots you see in Japan).
His "costume" is essentially his body. He wears a specialized suit that looks like a washing machine, but it’s integrated with his Quirk. His head pops out of the top, and he has these stubby little legs. It’s intentionally un-intimidating. In a society where heroes are often judged by how cool or scary they look, Wash takes the opposite approach. He is approachable.
Is There a Human Under There?
Yes. Susugu Mitarai is a human being. We don't see much of his "unmasked" form because the machine is the brand. In the MHA world, your brand is your life. If you’re a pro hero, you are a product. Wash has leaned into the product identity harder than almost anyone else, save for maybe Best Jeanist.
Addressing the "Gag Character" Stigma
Some fans get annoyed that Wash ranks higher than heroes like Ryukyu (the dragon hero) or Shishido. I get it. A dragon seems way more useful than a washing machine. But consider the reality of urban heroics.
If a dragon fights a villain in downtown Tokyo, the dragon might cause more damage than the villain. Wash, however, can neutralize a threat and clean the sidewalk at the same time. He is the ultimate "low collateral damage" hero. In the lore of My Hero Academia, the public is terrified of Quirks that cause destruction. They love Quirks that fix things. Wash is the embodiment of "fixing."
What We Can Learn From the Washing Machine Hero
Wash teaches us about the diversity of heroism. Not every hero needs to have "One For All" or a mastery over fire and ice. Some heroes just need to be there to pick up the pieces.
If you're looking for his best moments, check out the Pro Hero Arc (Chapter 184 onwards) and the first few volumes of the Paranormal Liberation War. He doesn't get a lot of dialogue—mostly just shouting "WASH!"—but his actions on the battlefield speak volumes. He is a reminder that in a world of monsters and gods, there is still a very important place for the person who cleans up the mess.
Actionable Insights for MHA Fans:
- Watch the Rankings: Re-read the Hero Billboard Chart JP arc to see how the public's perception of "safety" and "cleaning" directly influences a hero's rank.
- Check the Spin-offs: Wash makes brief appearances in My Hero Academia: Team-Up Missions, which gives a bit more flavor to his interactions with student heroes.
- Analyze the Quirk: If you're a tabletop RPG player or a writer, look at Wash as a template for a "Support" character. His utility isn't in damage, but in battlefield control and environmental manipulation.
- Observe the Background: In the later chapters of the manga (around 300+), look at how Wash is used in the refugee centers. His role as a provider of hygiene and comfort becomes even more critical when society collapses.
Wash is weird. He's a literal appliance. But in the grand tapestry of My Hero Academia, he’s one of the most successful and beloved pros for a reason. He does the dirty work that no one else wants to do—literally.
