Overview |
— Sitch on Blast[1] |
Blast (ブラスト, Burasuto) is the S-Class Rank 1 professional hero of the Hero Association.[2] He currently appears to be going to various places to collect the mysterious cubes, which is a hobby of his.[3] Only a few select Hero Association staff members have the means to communicate with him.[4] He is the father of Blue, the top hero of the Neo Heroes.[5]
Appearance[]
Blast is a tall, muscular middle-aged man with spiky black hair, a slight beard, and seemingly yellowish-green eyes. He wears bulky armor with large shoulder pads, a large cape worn out at the bottom, and emblems of his name on his chest and the backs of his shoes. His gloves have circles on the back of his fists, which form an infinity symbol when he presses them together to teleport. His suit shows signs of damage, presumably from his many battles. He also wears shades and has a scar running across his face between his eyes. The outline of his iris is a wavy black pattern, as opposed to just a consistent shape seen in other characters.
Eighteen years ago, when Blast first met Tatsumaki, his appearance was largely similar to today, but he looked younger and did not have a beard. Additionally, at that time, neither his armor nor his body showed any signs of damage or injury, and he did not wear shades.

In the webcomic, he sports the same spiky hair as seen in his manga appearances and appears to have a simple fabric suit with a front zipper outlined with a fiery contour.[6] His outfit looks similar to Saitama's Hero Suit.
His eyes appear the same as his purported son Blue's: they have multicolored irises, the light near the center but dark towards the outside. His hero costume also appears to be similar to Blue's battle suit, with the gauntlets of both suits having circles on the back of the hand.[6]
Personality[]
Blast does not disclose his personal information in the Hero Association Catalog. However, like Saitama, he considers his hero work a hobby. He also seems to have independent tendencies, keeping his location and status unknown and advising Tatsumaki to use her powers to defend herself rather than expecting others to save her.[7]
In the present, Blast exhibits a casual, easygoing demeanor. He does not seem to be very bothered by Saitama, Flashy Flash, and Manako touching a mysterious cube, simply explaining its nature to them. Blast was also not angered by the fact that Flash tried to attack him, simply telling him to calm down, and he was willing to teleport them out of the area they were in. He does not question Saitama's presence alongside an S-Class hero, and he answers Saitama's queries about his own arrival. However, he becomes momentarily serious upon recognizing Manako's monstrous nature. But after Saitama provides an explanation, Blast quickly reverts to his relaxed attitude, accepting the answer without further interrogation.[8]
Blast seems to not be completely out of touch with other heroes, as he recognized Bang, addressing the elder martial artist by his hero alias,[9] as well as recognizing Flash and knowing his exact ranking upon meeting him.[10] He also requested Flash and Saitama to send Sitch and Tatsumaki his regards.[11] Blast demonstrates a strong concern for the safety of the Earth, as evident in his efforts to minimize collateral damage when facing Garou, and his grave apprehension over the cataclysmic power unleashed during the clash between Saitama and Garou in the Ominous Future.[12]

In the original webcomic, Blast's attack on the Ninja Village also indicates that he doesn't show mercy towards humans who he views as evil, similar to Sweet Mask.[13]
History[]
For the past twenty years, Blast, Empty Void, and a group of many other collaborators have been searching for mysterious cubes that could turn humans into Mysterious Beings. They had attempted to analyze those cubes.[14]

Blast meeting Tatsumaki.
Eighteen years ago, Blast saved Tatsumaki from a hybrid monster. He then introduced himself to the young esper and questioned why she didn't use her psychic powers to save herself. Tatsumaki answered that her powers weren't working, but Blast realized she was lying. Knowing she still has her little sister, Fubuki, Blast told her not to expect anyone to save her, encouraging Tatsumaki to use her power and protect her only family.[15] Two years ago, Blast fought and nearly killed Elder Centipede.[16] While battling the centipede monster, he encountered "God" and after refusing the transaction of power from "God", he engaged in battle with the mysterious entity and managed to survive.[17] The sudden appearance of "God" was likely the reason Elder Centipede could escape from Blast. In the Hero Association, only Sitch was aware of that encounter, with Blast deciding to keep the existence of "God" from other people in the association.
Plot[]
Hero Association Saga[]
Alien Conquerors Arc[]
During the S-Class meeting, Child Emperor is slightly disappointed in Blast's absence,[18] which is later confirmed by Sitch who mentions his unknown whereabouts.[19]
Human Monster Saga[]
Monster Association Arc[]
Blast is mentioned in a Hero Association meeting. A staff member is frustrated at Blast's lack of activity despite being the top-ranked hero in the S-Class. Sitch says that Blast cannot be ordered around but has enough faith in Blast that should humanity be in peril, he will appear.[20]

Blast in Sweet Mask's vision.
When Drive Knight questions whether Blast would show up if the Hero Association Headquarters were attacked, Sekingar responds that it is unlikely, noting that Blast is more or less retired.[21]
During Sweet Mask's mental breakdown, he envisions Blast telling him everything is fine while a dead monster lies beside them.[22] This implies that Blast may have saved Sweet Mask from a monster in the past.
Tatsumaki also recalls a memory of Blast saving her from a monster 18 years ago. This flashback, along with the advice he gave her, motivates her to keep fighting despite her body's limits.[23] An object resembling the cube Blast held in Tatsumaki's flashback reappears during the Monster Association raid when Saitama pulls it out to free Flash's arm from rubble. The cube is extremely heavy, as it trapped Flash's arm, sank into the ground when dropped by Saitama, and Manako couldn't lift it.

Blast explaining what the cube is.
Blast suddenly appears to Saitama, Flash, and Manako after they hear the voice of "God" due to their contact with the cube. Blast notes his timely arrival and ensures they haven't accepted "the deal" yet. He briefly explains the cube's schematics and questions why Flash is so deep underground. When Flash tries to "test" him with his fastest kicks, Blast effortlessly dodges and reappears behind him. He explains that time flows slower in the space they're in and offers to take them to the surface. After Saitama explains why Manako, a monster, is with them, Blast relaxes and accepts the explanation before generating a portal, saying they'll meet again and asking the two heroes to send his regards to Sitch and Tatsumaki.

"I have to provide backup. I'm not fighting alone."
On the surface, Blast drops Saitama, Flash, and Manako near Garou before teleporting away to attend to his unknown business. Shortly afterward, he teleports to an unconscious Tatsumaki, who just resisted "God's" temptation, and checks on her. Now showing injuries that weren't there earlier, he comments on her growth. King and Saitama notice him, and Blast mentions that while he held "that thing" at bay, it made contact with Tatsumaki while he was in a time aperture created by the cube. He hands Tatsumaki to King, telling him to take care of her, before stepping through a portal, revealing he's not fighting alone.
Later, in another dimension, Blast and his companions detect a disturbance on Earth, caused by Garou's attack during his battle with Saitama, and move to repair an unknown seal holding "God" to prevent its release.

Blast battles Garou.
Afterward, Blast shows up during the heroes' standoff with Garou, now empowered by "God", confirming Bang's suspicion that Garou is unconsciously being controlled by the entity. He warns that Garou's cosmic radiation endangers all life, offering to take him to another dimension to protect the Earth. Noting Garou still retains part of his personality, Blast remarks that Garou has resisted full control by "God" and wonders what might have happened had he fully accepted the entity's power. Garou mockingly turns down the offer, declaring himself Disaster Level God and humanity's enemy. Bang tries to intervene, but Blast warns him to stay back. As Blast watches, Genos, using his remaining strength, hurls himself towards Garou and headbutts him, but it proves ineffective. When Garou picks Genos up, Blast intervenes, saving the cyborg and triggering a fight. Though Blast initially gains the upper hand with his speed and portals, Garou quickly adapts, copying Blast's abilities and pressuring him onto the defensive.
After a brief battle, Garou acknowledges Blast's strength but deems him unworthy of his time. Anticipating Saitama's return, Garou picks up Genos again and kills him by impaling him through the chest to provoke Saitama into using his full strength. Unfortunately, Blast is unable to intervene in time to save the cyborg this time. When Saitama finally returns, visibly distressed at being too late to save his disciple and the other heroes who succumbed to Garou's cosmic radiation, Blast warns him to stay away, unaware of Saitama's strength. However, Saitama, enraged, charges Garou with a Serious Punch, which Garou attempts to counter using Mode: Saitama to harness Saitama's striking power. Recognizing the immense energy behind their fists, Blast grows concerned that their clash will destroy the Earth.

Blast teleporting Saitama and Garou away from Earth.
Using his portal abilities, Blast quickly teleports Saitama, Garou, and himself far above Earth's surface before their fists collide. Upon impact, the shockwave released proves too powerful even for the highest-ranking S-Class hero, who struggles to redirect the destructive energy away from Earth. At this critical moment, three of Blast's companions arrive to assist him, and together they manage to divert the immense energy. A massive circular void forms in space, seemingly resulting from numerous star systems being wiped out by the redirected shockwave. Blast and his companions wonder how far Saitama and Garou have been sent flying from the recoil of their own punches.
Later, after Saitama travels to the past and defeats Garou before Blast can confront the Hero Hunter again in the new timeline, thereby saving the other heroes from dying of Garou's cosmic radiation and changing the Ominous Future, Blast in the current timeline retains no memory of what transpired in the Ominous Future (original timeline).
Neo Heroes Saga[]
Psychic Sisters Arc[]
After losing consciousness due to the exhaustion from her battle with Saitama, Tatsumaki sees Blast in her dream. She hopes that he will respect her after she has become as strong as she is now and will teach her a better way to live.
Ninjas Arc[]

Blast at the Hero Association Headquarters.
Upon meeting Sitch at the Hero Association Headquarters, Saitama, Flash, and Manako seek his help to contact Blast, only to find him already there. Blast greets them as Flash quickly dashes behind him like their first encounter underground, and asks about the battle against "God". Blast, again appearing behind Flash himself, explains he is there to discuss this issue. He confirms the connection between the Ninja Village where Flash was raised and "God", revealing that "That Man," the village leader, has awakened. Flash recounts his experiences in the village, noting that with Sonic, he saw a recovering "That Man" in a capsule and a mysterious cube nearby. He asks Blast if the true purpose of the village was to create pawns for "God," to which Blast affirms. Furthermore, Blast reveals that "That Man" has formed a group called the Heavenly Ninja Party, which he suspects will soon contact Sonic and Flash. After they move to Hero Apartment 104, Blast and the others listen as Flash recounts his and Sonic's past, including how he killed everyone in the village except Sonic on the day of his graduation exam.
Afterwards, Blast discusses with Sitch about Empty Void, the leader of the Ninja Village and his partner, whom he wants to free from "God's" influence. He is shown listening in on the conversation between the Heavenly Ninja Party and Sonic at the latter's hideout using some sort of eavesdropping device. When Flash receives a challenge letter from Sonic and goes to a mountainous area for their duel, Saitama hands Blast one of the challenge letters Sonic had sent him and says he will wait at Sonic's hideout. Overgrown Rover sniffs the letter and follows Sonic's scent, allowing Blast to track down the location of the battle between Sonic, Flash, and the Heavenly Ninja Party. He arrives in time to prevent unnecessary casualties, subdues the ninjas without killing anyone, and then teleports everyone to Sonic's hideout. There, they find Saitama sitting beside a figure-shaped crater. Blast explains that before he intervened in the ninja fight, he had arrived at the location, only to discover that Void had been defeated by Saitama.

Two divine beasts bursting through.
The Heavenly Ninja Party laughs, refusing to believe the story, and attacks Saitama, only for him to knock them all to the ground. Suddenly, a crack opens in the sky, resembling a dimensional tear. This occurs because Blast has strayed too far from his designated post. Byakko and Genbu, two divine beasts and guardians of "God", burst through from the Rift in Spacetime. They immediately wreak havoc, unleashing a powerful energy blast at those present. Blast envelops everyone in an energy barrier to protect them. The attack levels surrounding city blocks and causes widespread destruction. Void, now freed from "God's" influence thanks to Saitama knocking him out earlier, uses his Dimension Slash to slice through the beasts. Blast follows up with his Giga Gravity Blow, bombarding them with gravitational energy spheres that launch them skyward. He then seals the dimensional tear, sending the eliminated beasts back to where they came from.
Sonic and Flash move in to attack the now-freed Void, but Blast stops the two, explaining that Void only put them through hell at the village due to "God's" influence. However, they insist they were only testing Void's skills. Turning to Saitama, Blast notes that this is the second time Saitama has removed "God's" power from a minion. He tells Saitama that his strength will be crucial in the final battle against "God", and asks him to join the fight when the time comes. He then dimensional hops himself and Void to the Rift in Spacetime, where they surprisingly discover not just Byakko and Genbu's bodies, but also Kirin. Void asks Blast if he was the one who defeated it, but Blast says no, stating it is obvious who (Saitama) did.
Abilities and Powers[]
As the highest-ranking hero of the Hero Association, Blast stands as an exceptionally powerful combatant. Fubuki mentions that he "sits atop the hero world" during her talk with Saitama in his apartment, putting him alongside King in terms of power.[24] Sitch also mentions that he would only present himself if humanity is in peril and that he is valuable enough to receive special treatment over the other heroes.[25] In a display of his strength, he was able to bring Elder Centipede, a Dragon-level threat strong enough to combat the likes of Bang, Bomb, and Genos simultaneously, to the brink of death. However, Elder Centipede was smaller and presumably weaker when he first fought Blast. Despite this, Gyoro Gyoro believed that Blast could still defeat Elder Centipede even in his current state.[26]
Right before meeting Tatsumaki in the past, Blast could easily kill a giant monster that could smash through reinforced steel doors.[27] According to Sitch, he is the only hero able to fight against "God" thanks to his ability to manipulate space-time.[28]

Blast battles Garou, who has become influenced by "God".
Remarkably, Blast has proven capable of holding his own against Awakened Garou Cosmic Fear Mode, an immensely powerful and dangerous adversary whose abilities were enhanced by "God", a mysterious entity with terrifying supernatural powers, prompting the Hero Hunter to acknowledge his standing as the top-ranking S-Class hero. Due to his prioritization of preventing collateral damage on Earth and ensuring the safety of the unconscious heroes nearby, it's possible that Blast did not reveal the full extent of his abilities while fighting Garou.[29] Fifteen years ago, he fought and defeated Empty Void, the leader of the Ninja Village and his partner, who had also received power enhancements from the same entity as Garou. The injuries from that battle took Void 15 years to recover from.
In the databook, Fubuki speculates that Blast is stronger than King, can shoot lasers from his eyes and rules over psychic powers, and can command trillions of robots. She hypothesizes that he could beat the rest of the S-Class simultaneously.[30]
Physical Abilities[]

Blast outpacing Flashy Flash.
Immense Speed and Reflexes: Blast is incredibly fast and agile, being one of the fastest individuals shown. He has demonstrated his superiority over Flashy Flash, an S-Class hero well-known for his own extraordinary speed, by being capable of dodging the latter's fastest kicks from very close range and appearing behind him faster than Flash could perceive.[31] Notably, he could keep up with and fend off attacks from Garou in Cosmic Fear Mode,[29] who, even in a much weaker transformation, was already capable of covering vast distances in milliseconds during combat.[32] As another testament to his staggering reflexes and reaction times, when Saitama and Garou were rushing toward each other, Blast was able to activate his portal ability fast enough to transport both of them off the planet in the brief instant before their punches collided.[33]
Immense Strength: Blast possesses immense levels of physical strength, easily able to carry around a mysterious cube, even casually spinning it on his fingertip in a playful fashion.[10] Meanwhile, the aforementioned cube is heavy enough to cause Flash's arm to get stuck under it and sink into the ground upon being tossed away by Saitama.[34]
Space Survival: Blast appears capable of surviving in the harsh conditions of outer space for at least some duration. He withstood the cosmic radiation emitted by Garou without harm, despite its potency causing many nearby heroes to collapse and die shortly after.[29] Additionally, when transported beyond a breathable atmosphere, he showed no signs of distress in an environment lethal to normal humans.
Supernatural Abilities[]

Blast's portal-based teleportation.
Portal Creation: Blast possesses the ability to generate portals, which can resemble black holes. These portals allow him to teleport to various locations,[35] travel into different dimensions, and transport objects.[10] The size of these portals varies, with some small enough to fit a cube. For long-distance or dimensional travel, he usually clasps his fists together, forming an infinity symbol across his hands to generate a black hole-like portal.[36] Once opened, the portal enables teleportation that is either incredibly fast or instantaneous; for instance, it transported Saitama and Garou before they could strike each other, despite their fists nearly connecting.
In close-range combat, he can manifest smaller, circular spatial gateways without that gesture, using them to redirect incoming attacks or teleport short distances on the battlefield. However, he noted that the gates were bursting from the energy overload of Garou's attacks.[29]
Gravity Manipulation: Blast possesses the ability to manipulate gravity.[29] He can employ it to augment the force of his punches and hurl large spherical projectiles composed of gravitational energy for ranged attacks.
- Flight: Blast possesses the ability to float or levitate mid-air, likely linked to his manipulation of gravity.
Telepathy: Upon placing his hand on Tatsumaki's head, Blast experienced a vision of Fubuki and deduced their sibling relationship. This suggests that he might possess some form of telepathy or mind-reading ability.[37]
Energy Assessment: Blast possesses the ability to gauge the potency of attacks based on their energy levels. When Saitama and Garou were on the verge of colliding punches, he sensed that the immense energy contained in their fists could destroy the Earth, prompting him to teleport them off the planet before impact.
Fighting Style[]
Gravitational Portal Combat: Blast demonstrates a unique fighting style that combines spatial portals and gravity manipulation.[29] He employs these portals to redirect incoming attacks, strike from unexpected angles, deliver rapid consecutive blows, and forcibly transport opponents to different locations, as seen in his battle against Garou in the Ominous Future. Additionally, by manipulating gravity, he can enhance the power of his punches and launch large gravitational energy spheres for ranged attacks.
- Dimension Cannon (次元砲, Dimenshon Kyanon): By clasping his fists together, Blast shoots a miniature singularity toward his opponent.[29]
- Gravity Knuckle (重力拳, Gurabiti Nakkuru): Blast uses gravity to enhance his fists, allowing him to deliver powerful punches. He could knock Garou in his Cosmic Fear Mode around with this attack, albeit the Hero Hunter did not suffer serious harm.[29]
- Giga Gravity Blow (ギガグラビティブロー, Giga Gurabiti Burō): Blast channels gravitational energy into large, spherical projectiles and fires them in a rapid barrage from his fists. These spheres can slam or crush on contact with devastating concussive and crushing force. This attack was powerful enough to harm and hurl Genbu and Byakko, two divine beasts with a disaster level exceeding Dragon.
- Shut (遮断, Shatto): A dimensional sealing technique where Blast clasps his hands together to close overlapping portals or repair spatial tears.[29] This enables him to cut off dimensional access, trap enemies in alternate spaces, or seal breaches. For example, he used it to reseal Genbu and Byakko into a different dimension after their invasion of Earth.
Equipment[]
Mysterious Cubes: A series of cubic objects that enable humans to contact with "God" and transform into monsters.[38] Blast was shown to hold a cube when having a conversation with Tatsumaki 18 years ago,[39] and he later appears again to collect the cube touched by Saitama, Flash, and Manako.[40] It is also revealed by him that there are multiple of these cubes in various places.[41] The cubes can distort the space and time within its vicinity. Blast has been collecting these cubes as a "hobby" of his and teleports them to unknown locations.[40]
Battle Suit: Blast wears a combat suit that provides him resistance to damage in battles. It remains uncertain whether this suit is the source of his extraordinary abilities, such as portal creation, gravity manipulation, and energy projection.
Quotes[]
- (To Sweet Mask) "It's fine now."[42]
- (To Tatsumaki) "...I guess this is more of a hobby."[43]
- "When the time comes, don't go expecting someone to come save you."[44]
- (Regarding Garou) "I hope he'll listen to reason and come along with me, but if not...it'll be a battle for supremacy between two beings who manipulate the reality of the cosmos...to decide who is right and who is wrong...!"[29]
Trivia[]

Blast's previous debut in the manga.
- Blast's debut in the manga was originally less ambiguous, clearly showing a long head of hair and a cape. However, in the tankōbon release of the manga, his appearance was changed to be even more mysterious and equivocal.[45]
- Blast appears to share some traits with DC Comics superhero Superman, namely his hairstyle, status as the world's number one hero, and tendency to keep his personal life secret.
