One-Punch Man Wiki
"In order to ease the worries and fears of the people, we heroes have to be tough, strong, and beautiful at all times... always able to defeat evil swiftly and skillfully. That's what being a hero means."
— Sweet Mask[1]

Handsomely Masked Sweet Mask (イケメン仮面アマイマスク, Ikemen Kamen Amai Masuku; Viz Amai Mask, aka Handsome Kamen[4]) is the A-Class Rank 1 professional hero of the Hero Association. Apart from his hero profession, he is a famous model, actor, and singer and is the most popular star in the world.[5] In addition to his job as a hero, he is a member of the Hero Association hero rank evaluation staff.[2]

Sweet Mask's real name is Beaut (ビュウト, Byūto). He formed an obsession for Saitama's strength after witnessing his battle with Garou, stating that he possesses "the beauty of overwhelming power." He was aiming to create the perfect hero out of Saitama but is now on the run due to his monster self being revealed to the public. He is now dismissed from the Hero Association due to being a monster.


Sweet Mask is a tall and lean-built young man with messy shoulder-length light blue hair that has a single hair strand hanging down in the middle of his face and yellow eyes. He is considered to be very handsome by the public.

He wears a white jacket over his gray shirt with a green circle necklace and black trousers.

During the invasion of the Seafolk, he was sporting a shorter hairstyle with his hair parted to the right. He is seen with long hair again when he addresses the Hero Association official and, in his most recent appearance, he is again shown with his short hair. Interestingly, Sweet Mask's eyes seem to turn from a yellow into a blood-red when extremely angered.[6]

Sweet Mask used to be ugly, so he did hero work in a mask to hide his face. His original costume had a mask adorned with a question mark and a cape.

He only gained his beautiful appearance after transforming into a Mysterious Being due to his hatred for his ugliness.[7]

During his fight with Pesky Clown, Sweet Mask revealed the face underneath his mask. His true full form is that of a hulking hunchbacked monster.[8][9]

Because of his seeming Ugmon characteristics. Sweet Mask has the ability to alternate his biophysical semblance to the point of even masking his genetic & thermal signature.[10]

This would explain the differences in his appearances which some likened to plastic surgery.[11]


Sweet Mask has stated that he believes that heroes are to protect the citizens, and if they can't do that, they must become strong enough to be able to do so. He appears to be quite popular and has quite a charismatic way of talking. He also genuinely cares for the well-being of the citizens around him and wishes happiness upon every living thing in the universe.[12] Moreover, Sweet Mask can even stress himself out when thinking about new ways to please his fans.[13]

However, befitting the darker side of Sweet Mask's name, he has a hidden merciless nature. He is shown to have a burning hatred for anything that he sees as evil, including those whom he considers being evil’s accomplices and those who lend a helping hand to said accomplices.[14] Anything that he declares as evil must be swiftly and thoroughly exterminated.

Sweet Mask's darker side

This is shown when he mercilessly dispatches a group of captured aliens from the Dark Matter Thieves whom he declared to be evil, claiming to have merely executed justice on the spot, and again when he was ordered to bring an escaped caveman back to the lab. He ignored his superiors' orders and killed the caveman instead.[15] Sweet Mask also has no qualms in attempting to nearly murder brainwashed innocent victims like Narinki's Private Squad or considering the murder of fellow heroes Atomic Samurai's Disciples.[16]

Sweet Mask is shown to adhere to any method that makes heroes popular. He notes that only promotions to S-Class or A-Class are fit for his attention as they are the heroes who draw the most attention from the public, and hence, any heroes in those ranks who earn themselves negative reputations would drag his reputation down as well. Because of this, Sweet Mask stays in the A-Class Rank 1 position to prevent unworthy heroes from promoting to S-Class. He also places high value in his own popularity and status, demonstrating a very narcissistic and highly opinionated view of himself. Sweet Mask puts such a priority on his status and reputation that he is willing to go so far as to consider murdering all the S-class heroes present at the raid to ensure that the Hero Association doesn't hear of his failure against Fuhrer Ugly and the way he lost his composure, but he regains his self-control at the last second.[17]

Sweet Mask's narcissistic side

Sweet Mask is very narcissistic about "beauty overwhelming the power", as he mentions of his philosophy that "heroes have to be beautiful as well". This is obvious when he showed interest in a worthy S-Class Hero such as Genos, who has both a beautiful appeal and has done numerous heroic deeds as the main priority, fitting Sweet Mask's philosophy. This is also shown when he chews out the S-Class heroes whom he believed were unworthy of their positions, opting to subordinate them while filling in as team leader of the Monster Association raid.[18]

Likewise, Sweet Mask has infinitely less love for people who succumb to the power of evil he so venomously despises. His hatred of monsters, coupled with his sense of beauty and justice, makes him venomously condescending towards others whilst propping up his own self-righteousness.[19] This is shown when he questioned Zombieman's credibility as a human being, much less a hero, going by his odd abilities and asking why he couldn't die during the S-Class hero meeting.[20] He even goes so far as to secretly contemplate murdering the other heroes due to his intolerance towards them potentially judging him and having a descanting view on the jaundiced account of his being glamorous.[21]

In spite of his negative personality traits, Sweet Mask does genuinely want to help people and fight evil. It's implied that fame and reputation have simply gone to his head and he often forgets the reasons he wanted to be a hero in the first place. This is demonstrated by how he can respect people for their courage and resolve as he was surprised when he had been told that King had been fighting monsters all night by himself with his mood changing to pleased while complimenting King and expressing his admiration.[22] Later, when he contemplating killing the S-class heroes to hide his failure during the Monster Association Raid, Iaian asked him if he was fine. This immediately triggered a memory in Sweet Mask showing a time when he was saved by the number one hero, Blast, who told him it would be fine after saving Sweet Mask from a monster. This flashback had a deep impact on him as he immediately started to bash his head against the ground to regain composure and curb his murderous urges. He later smiled and stated that he almost forgot the most important lesson, "which would be self-control".[23] Sweet Mask had also been willing to help who he believed was a regular person to get away from the battle with the monsters. He even aided an injured Metal Bat while also attempting to save Flashy Flash from what he assumed to be Manako trying to kill him.

However, after witnessing the defeat of Garou by Saitama, his viewpoint changes and becomes more focused on the overwhelming power of the individual than beauty alone.[24]

Sweet Mask wholeheartedly believes in a grand justice that will illuminate the world, and a hero who represents a great hope that everyone can see and latch onto.[25] His plan is to have Saitama be the symbol he envisions.[26]

His hatred for all things ugly stems from the fact that he himself once had an ugly face and chose to wear a mask out of shame. This intense hatred of his own ugliness caused his body to change and for him to transform into a Mysterious Being. Before he became a Mysterious Being, he attempted to be beautiful on the inside and adhere to strict moral principles. Even attempting to perform good deeds for the community, such as picking up litter, though no one paid attention to him for said kindnesses. But when he transformed into a handsome man, his popularity skyrocketed to where it is now due to his extremely good looks. He initially viewed the public as vain for being blinded by outward beauty, but realized that he'd become just like them.[27]

Sweet Mask reveals that his transformation has begun to corrupt and monsterize him, being responsible for the more bloodthirsty and ruthless side of him and making him lose his humanity. Killing monsters has been the only way he's stayed on humanity's side but it has made him more merciless as a consequence. This mercilessness even makes him, when faced with a choice where he can only save one side, choose to sacrifice the one with the smallest number without hesitation and act as if he struggled with the choice. According to Sweet Mask, he will eventually view justice as just another symbol and completely cease to understand what it means to be human, something which he fears greatly.[28] For all his vain and self-serving traits, Sweet Mask possesses a certain degree of selflessness, as he willingly transformed into his monster form to defeat Pesky Clown despite knowing that there were people watching and that doing so would mark the end of his career as both a hero and an idol.[29]

Abilities and Powers[]

As the top-ranked A-Class hero, Sweet Mask is a very skilled and powerful individual. He is also far superior to everyone else in this class and his skills are strong enough to put him in S-Class. He claims to be stronger than Atomic Samurai,[30] and is even confident enough in his abilities to stand up to other S-Class heroes, such as Flashy Flash.[31] He chooses not to advance to S-Class so as not to allow weaklings to rank up.[32] Fubuki describes him as a monster, much like her sister Tatsumaki, who is the second highest-ranked hero within the association. Even after witnessing Saitama's display of power in his fights against her and Speed-o'-Sound Sonic, Fubuki was still convinced that it would be impossible for him to surpass Sweet Mask.[33] Along with his previous claims, Sweet Mask describes himself as an "all-rounder" capable of defeating "any opponent" and is confident in proclaiming himself as "the perfect hero".[citation needed] However, he has a very peculiar weakness; extreme ugliness paralyzes him, making him unable to move well and fight back, which renders him particularly vulnerable against Ugmons.[citation needed] Besides his combat abilities, Sweet Mask is a talented actor and singer.

As confirmed by Atomic Samurai, he's definitely S-Class worthy, and can take on multiple Dragon-level opponents at once.[34] Despite this, he states that he has never defeated a Dragon-level Mysterious Being by himself.[35] Once he transforms into his monster state, he's strong enough to overpower Pesky Clown, a Dragon-level threat, with only a few blows, even breaking his arm. Even when Pesky Clown powers up further, although initially overwhelmed, Sweet Mask still manages to put an end to the Dragon-level monster.

Physical Abilities[]

Sweet Mask swiftly killing several hostage aliens

Immense Speed and Reflexes: Sweet Mask is extremely fast as he was able to kill a group of captured alien invaders before the nearby S-Class heroes could react.[36] He also effortlessly evaded Suppon's barrage of attacks and maneuvered behind him, striking him down with only two blows before the caveman could retaliate.[37]

More remarkably, he managed to fight off several clones of Black Sperm, a Dragon-level monster. He was also able to dodge some of Evil Natural Water's attacks, which, according to Child Emperor, move faster than the eye can register, while still fighting against Black Sperm.[38] When attacking Garou, he managed to land 25 hits within seconds.

Sweet Mask slices two monsters in half with his bare hands

Immense Strength: Sweet Mask possesses incredible brute strength. During a concert, he forcibly manipulated a monster's movement without interrupting the flow of the performance and with just one hand, he easily sliced other two monsters in half and punched a monster with such force that its head was obliterated.[12] He is also able to effortlessly lift and throw large pieces of rubble away with only one arm,[39] as well as being able to utterly crush Do-S's head, a Demon-level Mysterious Being, using only one hand.[40] Furthermore, Sweet Mask is strong enough to destroy the tanks that housed the Monster Cells with a few swipes.[citation needed]

Warning.png Expand to see original webcomic information. Beware of spoiler content.

He was able to lift a boulder much larger than he is with ease, as well as throwing it with great force. He also broke the hand of one of Black Sperm's giant clones with a single hit.[41] Once he transforms into his monster state, his strength skyrockets. He's able to stop Pesky Clown, a Dragon-level threat, in his tracks, breaking his arm and defeating him rather quickly. Even after the monster powered up further after receiving attention and news coverage from the entire world, Sweet Mask is still strong enough to kill Pesky Clown with a single blow to the head.

Immense Endurance: Possibly due to his abnormal body, Sweet Mask seemed to feel no pain upon being pierced through the chest by Evil Natural Water, and resumed fighting normally.[42]

Sweet Mask's distorted face

Abnormal Body: By unknown means, Sweet Mask was able to reattach his severed arm. According to himself, he was able to reattach it as it was a clean cut. He was also somehow able to regenerate his smashed face after Garou punched it. Sweet Mask's body seems to be capable of healing quickly from potentially lethal wounds. However, he doesn't seem to have the ability to regrow a severed limb, as he reattached his arm instead of just regrowing it.[43] Additionally, something peculiar about Sweet Mask is that when angered, his body mutates, and the veins in his face grow in size. This is revealed to be because he is in fact a Mysterious Being who mutated due to his intense hatred for ugliness.

  • Transformation: Sweet Mask can transform into his true monster form to increase his power and strength. This causes veins to pop up all over his face and causes a huge increase in power.[44] In this form he is capable of easily defeating Pesky Clown, a powerful Dragon-level Mysterious Being. Webigaza states such metamorphic capabilities also enable him to not only disguise his physical appearance, but also mask his biophysical signature in order to avoid detection even from sophisticated spy sat technologies. Indicating he is not merely limited to switching between human and monster form.[45]

Regeneration: Through unknown means, Sweet Mask possesses the ability to quickly recover from extreme injuries to his body. This was first seen when Do-S pierced his eye with her tongue and cracked his face with the damage having healed almost instantaneously.[46] After getting his torso ripped open, exposing even his intestine, and having his face flattened by Fuhrer Ugly,[47] Sweet Mask was able to fully regenerate from all the damage over an unknown period of time.[48]

Fighting Style[]

Sweet Mask's fighting ability

Expert Hand-to-Hand Combatant: Sweet Mask is a very skilled fighter. During his fight against Suppon, he first moves in the latter's blind spot, incapacitates him, and then delivers a lethal strike.[37] Combining with his superhuman strength and speed, Sweet Mask's hands act as a sharp blade that he usually uses to slice monsters in half.[49][12]

He managed to repel the continuous assault of Black Sperm's clones, who easily broke through Atomic Samurai's defense, prompting the latter hero to comment that Sweet Mask and Black Sperm were even, at least temporarily.[34]

Miscellaneous Abilities[]

Mental Resistance: Sweet Mask was able to completely resist Do-S' mind control whip.[50]
