Let's be real about Do S One Punch Man. Most fans remember her for exactly one reason, and it’s usually the whip or the heart-shaped hole in her mask. She’s the Monster Association’s "Monster Princess," a Demon-level threat who basically turned the concept of mind control into a leather-clad nightmare. But if you strip away the fan service—and there is a lot of it—there is a surprisingly complex bit of world-building attached to her character that most people totally miss while they're busy arguing about power scales on Reddit.
She’s terrifying. Not because she can punch a hole through a skyscraper, but because she takes away agency. In a world like One Punch Man, where "willpower" is literally the source of Saitama’s god-like strength, a villain whose entire gimmick is breaking that will is actually the perfect thematic foil.
The Absolute Chaos of the Do S One Punch Man Redraws
If you’ve been following the manga, you know Yusuke Murata is the king of the redraw. It’s a blessing and a curse. Do S One Punch Man is perhaps the biggest victim (or beneficiary, depending on who you ask) of these constant changes. Originally, her encounter with Sweet Mask was dark. Like, really dark. In the initial version of Chapter 103, Sweet Mask cold-bloodedly executes her and her brainwashed slaves without a second thought. It was a moment meant to show us that Sweet Mask is arguably more "monstrous" than the monsters he hunts.
Then Murata changed his mind.
In the revised version, she survives. She pleads for her life, manages to escape, and pops back up later in the story. Why? Because Murata and ONE realized she was too useful of a narrative tool to kill off so early. By keeping her alive, the story could explore the friction between the surface world and the Monster Association with a character who actually had a personality beyond just "hungry beast."
It changed the tone of the entire arc.
Suddenly, we weren't just looking at a linear path to the big boss. We were seeing the internal politics of the monsters. Her survival also allowed for that weird, tense standoff with Fubuki. If you compare the original webcomic by ONE to the Murata manga, the role of Do S One Punch Man is one of the most expanded parts of the entire series. She went from a minor obstacle to a recurring symbol of the psychological warfare monsters use against the Hero Association.
Power Levels and the Love-Whip Mechanic
She isn't a physical powerhouse. If she went toe-to-toe with someone like Darkshine, she’d be a red smudge on the pavement in four seconds. But that’s not the point of her character. Her "Love-Whip" is a neurological weapon. One strike and you aren't just hurt; you're a puppet.

This is where the lore gets interesting.
The slaves she creates are called "Love Slaves." It sounds ridiculous, but in the context of the series’ "Monsterfication" lore, it’s actually quite consistent. We know that in the OPM universe, strong emotions or obsessions can turn humans into monsters. Do S taps into that. She forces a physiological obsession onto her victims. We saw this clearly during the raid when she turned the Private Squad of the mercenary group into her personal vanguard.
It highlights a major flaw in the Hero Association's recruitment. They hire based on physical stats, but they have zero defense against psychic or biological subversion.
Why Do S and Fubuki are Perfect Rivals
The fight between Fubuki and Do S One Punch Man is one of the best examples of "style vs. style" in the series. You have Fubuki, who leads the Blizzard Group through a mix of charisma, intimidation, and a massive inferiority complex regarding her sister, Tatsumaki. Then you have Do S, who leads through literal, forced magical compulsion.
They are two sides of the same coin.
Fubuki wants a "group" because she’s afraid of being alone and weak. Do S wants a "group" because she’s a narcissist who needs constant validation through subservience. When they clash, it isn't just a psychic battle; it’s a battle of leadership philosophies. Fubuki’s growth during the Monster Association arc is partly triggered by seeing what "absolute control" actually looks like. She realizes that she doesn't want to be a tyrant like Do S; she wants to be a leader.
Honestly, without the threat of Do S, Fubuki’s character development would have felt a lot flatter during those middle chapters.

The Design Controversy
We have to talk about it. The design of Do S One Punch Man is... aggressive. Murata is famous for his "extra" character designs, and Do S is the peak of that. She wears a BDSM-inspired outfit that feels a bit out of place in a series that also features a kid with a giant butt for a chin.
Critics often point to her as "unnecessary fanservice."
There's some truth to that. But from a character design standpoint, her look tells you exactly what she is. She’s a Dominatrix. Her power is domination. It’s visual shorthand. In a manga where characters like Deep Sea King represent "The Brute" and Boros represents "The Conqueror," Do S represents "The Corrupter." Her design is meant to be provocative because her entire existence is about subverting the "pure" intentions of heroes.
What Most People Get Wrong About Her Rank
Because she’s a Demon-level threat, people assume she's weak. In the grand scheme of things—especially when you have Dragon-level threats like Black Sperm or Overgrown Rover running around—a Demon-level seems like small fry.
But rank in One Punch Man isn't just about destructive capability. It’s about the "danger to humanity."
If Do S One Punch Man had stayed in the shadows and slowly brainwashed the top brass of the Hero Association, she would have been a God-level threat without ever throwing a punch. That's the nuance people miss. The Monster Association lost because they tried to fight the heroes in a physical war. If they had utilized Do S more effectively for espionage and subversion, Saitama might have been the only hero left standing.
The Mask and the "Human" Element
One of the most telling details about Do S is her mask. It has a heart-shaped hole, but underneath, she looks surprisingly human compared to someone like Fuhrer Ugly. This is a common trope in ONE’s writing. The more "human" a monster looks, the more they represent a specific human vice.

Do S represents the desire for power over others.
She isn't a mindless animal. She talks, she schemes, and she feels fear. When she was cornered by Sweet Mask, her facade crumbled. That moment of pure, raw terror showed that despite her "Monster Princess" persona, she’s just as vulnerable as the humans she tortures. It’s that contrast that makes her more interesting than a generic giant lizard.
How to Scale Do S in Your OPM Discussions
If you're one of those people who spends hours on VS Battle wikis, you need to be careful with how you categorize her.
- Attack Potency: Low Demon. Her whip can break concrete, but it's not world-shattering.
- Hax/Abilities: High Dragon. Her mind control is nearly instantaneous on anyone without significant psychic resistance or an absurdly strong "Spirit."
- Durability: Moderate. She can take a few hits from A-class heroes, but any S-class hero would end her quickly if they closed the gap.
- Speed: Above average. She’s fast enough to keep up with Fubuki’s wind-based attacks, which is no small feat.
The mistake is treating her like a brawler. She's a support/utility villain. In a team fight, she's the most dangerous person on the field because she turns your allies against you.
Actionable Takeaways for Fans and Lore Hunters
If you want to actually understand the impact of Do S One Punch Man on the series, you should stop looking at the "best moments" compilations and actually do a side-by-side read of the manga volumes.
- Read the Redraws: Compare Chapter 103 (original) and Chapter 103 (revised). It is the single most important piece of evidence for how ONE and Murata's storytelling evolved during the raid.
- Watch the Fubuki Parallel: Pay attention to how Fubuki reacts to Do S's "slaves." It directly mirrors Fubuki's own internal struggle with her "Blizzard Group."
- Note the Limits: Notice who doesn't get affected by her whip. It’s a great way to gauge the "Willpower" stat of various heroes.
Ultimately, she’s a reminder that in One Punch Man, the monsters aren't just there to be punched. They are there to test the heroes' souls. Do S just happens to do that with a whip and a very questionable outfit. She isn't the strongest, and she definitely isn't the smartest, but she remains one of the most memorable villains because she forces us to look at the darker side of "influence" and "control."
The next time you see her pop up in a panel, don't just look at the art. Look at what she's doing to the social fabric of the heroes around her. That's where the real horror—and the real story—is hidden.
