Garou/Synopsis

History
As a child, Garou was unpopular and an social outcast. At school, while he was reading a book, a popular boy named Tacchan approached him and wanted to play heroes with him, in which Tacchan declares Garou to be the monster after he tried to make Tacchan realizes how dangerous it was to kick a person from high groud and himself to be Justice Man. He tried to kick Garou, Garou dodged, but after Tacchan missed and hurt himself, to which Garou apologizes. Tacchan asked him what was he doing, pointed out that Garou was the monster, and then kicked him in the face while making others kids to restrain him. Later Garou tried to stand up for himself by making Tacchan to fight him to make him realize that he cannot bully Garou anymore, but the other children gathered around and started defending Tacchan, saying it was just how the game works. Tacchan then cowardly asked others children to pin Garou to the ground and called the teacher while running away. Garou noticed how Tacchan was the one always smiling, liked by everyone, and was good at everything, even though he was a jerk; while Garou was alone, gloomy, and had no friends. When talking to his uncaring and unsympathetic teacher, s/he ignored Garou and simply lectured him on how he should not be fighting and what might have happened if it had continued as well as reprimanding him for not distinguishing reality and game. After s/he was done, s/he forced the crying Garou to apologize and then notified his parents. Garou eventually snapped and began to see that heroes are nothing more than a bunch of bullies who are preying on the weak and outcast of society like him while receiving praises from others people who equally hate the outcast.

On another occasion, Garou watched the Justice Man TV show and was always rooting for the villains to win. He became frustrated every time Justice Man comes and stops them. He asked his father when there would be a villain that could defeat Justice Man, but only to hear the negative; he believed it did not make sense, as he reasoned that the monsters the ones who are always trying their best, but no matter what, they were always killed off unfairly in the end simply because they are monsters. Unwilling to accept the status quo, Garou resolved to become the strongest monster and never lose, and to change the scenario.

Sick of being a helpless kid throughout his childhood. As an adult, he joined Bang's dojo and became Bang's top disciple. Six months prior to the Super Fight martial arts tournament that Saitama attended, he decided that he has nothing left to learn and rampaged through the dojo, disabling many of the students, including Sour Face. He then received a beating from Bang and was expelled from the dojo.

After his expulsion, Garou attended the Super Fight, disguising himself as Wolfman after incapacitating the real one and taking his mask. Garou won the tournament, although his identity remained unknown.

Alien Conquerors Arc
Garou was mentioned by Bang, after Genos questions him about his dojo being filled with skilled fighters, after defeating Bangs "best disciple" Charanko. Bang reveals that the dojo used to be filled with skilled fighters until his best disciple, Garou, went on a rampage and disabled them all for life, scaring the rest away as well. Because of this, Bang expelled Garou after giving him a beating.

Garou Introduction Arc
During a meeting in the Hero Association headquarters in the middle of a coalition between a large group of villains and the Hero Association. He states himself as an extremely powerful individual, able to beat every present person alone even if they gang up on him. He reveals that his presence on the location was merely to find strong opponents and to punish the cowards. After three heroes agree on taking him down it's revealed that Garou never liked heroes and always supported monsters because of his sympathy for their ambitions. After the flashback, he promised to become the strongest monster and change the scenario. He attacks three A-Class heroes border-lining S-Class in strength and beats up everyone present with the exception of Sitch and Speed-o'-Sound Sonic as Sonic had left said meeting pre-haste. As he leaves proclaiming this was the epic intro of Garou the Human Monster, he promises to come bursting through the front door of the Hero Association in three months time after his training journey was over. Musing perhaps he will fight King, the strongest hero in their ranks one day while out on his jaunt.

The Blizzard Group Arc
After his rampage at the meeting, it's been revealed that Garou has the reputation and the title of "Human Monster" within the Heroes Association, however, no one sees him as a threat beside Sitch. Garou later happened to encounter an upper A-Class hero Tanktop Vegetarian in an empty alleyway. He easily defeated the hero, but was disappointed by the fight. When Tanktop Vegetarian threatens him about messing with heroes, Garou simply knocks him out, proclaiming excitement to fight a monster class hero.

Hero Hunt Arc
Garou later meets C-Class hero Mumen Rider and threatens to attack him, but not before Tanktop Vegetarian, whom Garou has beaten and spares him in last afternoon, calls his Tank Topper Army to exact revenge against Garou. Suddenly, S-Class hero Tanktop Master appears and punches Garou, after Garou knocked out Tanktop Vegetarian.

Mumen Rider defends Garou from Tanktop Master's attack, but Tanktop Master knows about Garou's evil intents and the possible threat he's posing, and reaches for the finishing blow. Garou counterattacks with his special technique Water Stream Rock Smashing Fist and beats Tanktop Master with ease. Tanktop Master then realizes that Garou was merely holding back. Garou then proceeds to attack all heroes present alongside Mumen Rider and Charanko, the bodies of whom are found by Bang and Bomb. Garou later interrupts the conversation between three C-Class heroes and proceeds to beat them up. Afterwards he finds Tareo, a child with a catalogue, containing info about the heroes. Garou asks the kid for the catalogue, but the kid refuses. Garou's interest furthers once he learned that the catalogue contained information about monsters as well. Garou ends up reading through the catalogue to find out Golden Ball's location. Garou finds Golden Ball in a bar and challenges him into a fight. Golden Ball eventually accepts and they head towards the parking lot. It is revealed that Golden Ball was putting up an act and begins the fight in the alley heading towards the parking lot. Garou dodges Golden Ball's first two attacks. Golden Ball initially believes that Garou was able to dodge them because of his hand movements and then shoots a shot that ricochets and pierces Garou's leg. Golden Ball, believing that he has the advantage now, follows up with Golden Breakout. However Garou effortlessly dodges all of them, thus refuting Golden Ball's initial thought that Garou used Golden Ball's hand movements to dodge his bullets. In a final effort, Golden Ball fires one more shot directly at Garou. Unfortunately, Garou was able to deflect and destroy it and then destroys all of the other bullets. Before Garou can attack Golden Ball, Spring Mustachio appears. Spring Mustachio then starts swinging in every direction forcing Garou to jump. Spring Mustachio then initiates his secret move, Tomboy. Garou dodges the attack, but his left hand got stabbed. Succeeding the dodge, Garou punches Spring Mustachio, launching Spring Mustachio into several trash cans and crates. Garou reveals that he knew about Spring Mustachio's secret technique and that he is now used to armed combatants.

After the fight he went on to target Sweet Mask, by chance he overheard a corrupt officer of the Hero association using his position and the heroes' name to pick up chicks and proceeded to clobber him in annoyance. Irked with dissatisfaction at the official he beat up, Saitama just happened to be around finding a wig shop, which is directly in front of Garou. Thinking Saitama is a small fry who thinks he can make a big name by arresting him, Garou attacked Saitama, sinking his feet into the ground from the impact. Unfazed, Saitama delivered a chop of his own to Garou's nape, knocking him unconscious as he proceeded to buy a wig. Garou eventually woke up on a pile of garbage bags with a fuzzy memory.

Monster Raid Arc
Garou return to his hideout, wrapping his injuries and checking the wall of photos of heroes he possibly wants to fight. Garou is later seen talking with Tareo, the same child with a catalog and asks him the whereabouts of the S-Class hero Watchdog Man, with the intention of fighting him. However, their conversation is interrupted by S-City's alert about a Demon level monsters and Metal Bat. Garou then tells Tareo to run while he looks forward to fighting Metal Bat.

Garou arrives to the scene just when Metal Bat is launched hundreds of meters across the city. Initially believing Metal Bat got defeated by Elder Centipede, Garou decides to go after Watchdog Man. However, Metal Bat soon gets up and begins heading back to fight Elder Centipede. This causes Garou to attack Metal Bat. Garou is later seen fighting Metal Bat on a empty city, and comments that he's disappointed that he was being unable to see Metal Bat's true strength due to the exhaustion of his fight against Elder Centipede. Metal Bat retaliates against Garou's comment with an attack, but Garou manages to dodge it. Garou is surprised by Metal Bat's persistence despite Metal Bat's numerous injuries, but insists that Metal Bat is at his limit. Suddenly, Metal Bat rushes to Garou with incredible speed. Garou still manages to avoid Metal Bat's attacks and attempts to counterattack, but Garou's attack are no longer able to faze Metal Bat either. Garou notes that Metal Bat's speed and attack power have increased drastically. Garou asks Metal Bat for the reason for this sudden increase in physical strength and Metal Bat simply explains that "It's Fightin' Spirit!". Metal Bat tells Garou to hurry up with the fight. Garou replies that he'll play for a little bit to see how long Metal Bat can keep up his fighting spirit.

Garou throws a manhole cover at Metal Bat, but Metal Bat hits it back with his bat. However, Garou already managed to reach Metal Bat by the time Metal Bat followed through. Metal Bat tries the take the offensive, but none of his attacks connect. Garou continues to mock Metal Bat, asking him if he's going to persist until he dies. Metal Bat retorts by saying he'll fight until he wins and continues to attack. Garou tries to kick Metal Bat, but Metal Bat deflects it and proceeds to initiate a killing move. Fortunately, Garou manages to fairly easily repel the technique and launches a blow to Metal Bat's chest, leaving Metal Bat laying on the ground. Garou dismisses Metal Bat and Tanktop Master as hot-blooded idiots who lack counters to anti-human martial arts. Nonetheless, Garou notes that, despite being able to repel all of Metal Bat's attacks, his bones are shaking and if Metal Bat had hit him, even once, it would have ended badly. Abruptly, someone shouts, "Big Brother!". Metal Bat is about to land a powerful blow on Garou, but stops because he hears his sister's voice. Garou then punches Metal Bat and comments that Metal Bat might have ended the fight if he did not stop the swing midway. Before the two could clash again, Zenko, Metal Bat's sister, jumps in the front of Metal Bat and says to Garou the fight is over because her brother promised to not fight in front of her. Though reluctant, Garou accepts and then leaves the fight to look for Watchdog Man.

While leaving, Garou is being watched over by Phoenix Man and Sludge Jellyfish. They discuss that Garou could be useful. When Sludge Jellyfish tries to capture Zenko, it is attacked by Garou, stating that he does not like being watched. Phoenix Man quickly comes and tells Garou that they are not enemies. Both monsters try to be friendly and invite him to the Monster Association. Garou turns them down and demands them to leave. The Mysterious Beings decide to leave, but say to him that they will definitely meet again later if Garou continues to hero hunt. When the monsters are finally out of sight, Garou simply says, "Disgusting".

Super Fight Arc
Garou reaches the Watchdog Plaza to search for Watchdog Man. Watchdog Man is sitting on top of what was a Monster Association invasion force of many monsters. Garou attempts to attack Watchdog Man while the hero is sitting.

However, due to Garou's underestimation of Watchdog Man, he quickly becomes overwhelmed by Watchdog Man's fast and powerful attacks to the point that he cannot even read his wild and unpredictable movement. All the training he had been through with Bang was never meant to be used to fight monsters and as a result, all his techniques were countered effortlessly by Watchdog Man. After being severely injured by Watchdog Man, he runs away and Watchdog Man stops chasing him once Garou escapes his territory. Despite the outcome, he feels excitement about the battle since he now has the experience needed to battle monsters properly and embraces the happiness that he can become stronger.

During this time, he sees King and Saitama in which he tries to attack King, despite his injuries. As he is about to confidently lay a hit on King's body after reading all of his possible movements, he fails to notice Saitama. As a result, he is sent flying by Saitama with a single kick and smashed through a wall.

Monster Association Arc
After recovering from being knocked into a wall, he unintentionally encounters Death Gatling and decides that it's best for him to recover and rest due to the injuries he sustained from Watchdog Man and King (Saitama). As he stumbles away, Death Gatling looks over and spots him.

Garou is seen recovering from his injuries in his hideout and re-encounters Tareo. Tareo explains to Garou he has to leave the hut, but Garou figure Tareo was bullied into it. Garou tells Tareo that if he wants to stand up to his friends he has to become strong, which Tareo already knew. Garou then felt being surrounded and asks Tareo for the hero catalogue. Garou asks Tareo for the hero catalog to identify each one of the heroes outside his shack. After identifying all of the heroes, he proceeds to exit the shack. Death Gatling tells Garou that they are here to capture him, but Garou retorts that with Death Gatling and his group, the hero hunt will surpass 100 heroes. Gun Gun quickly opens fire on Garou, but Garou easily dodges and attempts to counterattack. However, he is forced to dodge again because of Stinger's attack. Stinger's attack is quickly followed up with Arrow Rain from Shooter, which Garou also manages to dodge. Chain'n'toad begins the next wave of attacks as Smile Man attacks from above as Wild Horn attacks from behind.

Gun Gun manages to land a hit as tries to attack Wild Horn. Stinger follows up and manages to cut Garou's arm. Garou notices that Glasses lack of action, but is then hit by Chain'n'toad's weapon and attacked by Smile Man again. Chain'n'toad uses his Ear Cutter technique, but failed to injure Garou a second time. Smile Man and Chain'n'toad proceed to continuously barrage Garou before the Human Monster has any time to recover. Arrow Rain comes down as Smile Man, Chain'n'toad, and Gun Gun attack all at once. Despite twisting in the air, Garou is hit by two of the arrows. Glasses resupplies Shooter before Garou tries to go after the hero. Glasses manages to dodge Garou's initial attack and lands a hit on Garou as the Hero Hunter is distracted by the heroes behind him and the pebbles thrown by Glasses. Afterwards, Death Gatling gives Garou one last chance to surrender.

As he continues to fight the heroes, flashbacks of his childhood come back to Garou, as he remembers all of the villains that were unfairly defeated just because they were outnumbered by the heroes. Chain'n'toad attacks Garou with his chain, but to his surprise, Garou managed to intercept the chain, even though the chain was aimed at his blind spot. Smile Man then attacks Garou from behind with his kendama and throws it at him. Garou, however, catches the kendama and redirects it toward Chain'n'toad, taking him out of the battle. Gun Gun fires his pistol at Garou, but Garou uses Smile Man's kendama to shield himself from the bullets. Then, he propels the kendama toward Gun Gun, knocking him out in the process. The next hero who attacks is Wild Horn, who uses his Pile Bison and destroys the kendama.

However, Garou wraps the chain from Chain'n'toad around Wild Horn's legs to prevent him from escaping, and also preventing Shooter from firing his poisonous arrows. Glasses then throws several pebbles at Garou while he was distracted, but Garou easily catches the pebbles. Taunting Glasses by saying it was just what he needed, he threw the pebbles with blinding speed at Shooter, effectively knocking him unconscious. Stinger attempts to strike him with his Roaring Bamboo Shoot Gigantic attack, but Garou once again uses Wild Horn as a barrier. Garou then runs toward Stinger at full speed, telling him it would be a one-on-one, to which Stinger accepts, telling the other heroes to stay out of his way. But just as Garou is going to strike Stinger, he changes his target and hits Smile Man square in the jaw, taking him out of the fight.

Next, Death Gatling fires at Garou, to which Garou dodges, all the while running to his next target: Glasses. Garou strikes him with a barrage of punches. Glasses attempts to retaliate with a right punch, but Garou blocks the punch and hits him square in the jaw. A few meters away, Stinger decides to intervene and save Glasses from this torturous onslaught and attacks Garou with his Gigantic Drill Stinger, but Garou expertly intercepts the bamboo and counters with a left punch to Stinger's face, continuing with a consecutive string of blows to his chest.

Behind him, Glasses works through the pain and tries to strike him, but Garou nails him hard in the stomach with a right elbow, removing him from the battle. With only Death Gatling remaining, the hero states to Garou he considers him a monster, revoking his previous idea to take him alive and declaring he will finish him off. Garou tells him not to attack, as a child is in the building behind him, but Death Gatling ignores his words. Death Gatling uses his ultimate attack: Death Shower, in which he quickly empties all of his bullets and fires a very quick round of bullets. Alas, Garou manages to intercept all of the bullets, leaving the building behind him still standing.

After receiving an emergency call from Glasses, who is with Death Gatling and their group of heroes to ambush Garou and failed, Genos arrives to fight the already extremely weakened Garou. Genos and Garou's fists collide midair, propelling Garou back. Genos follows up his attack with his Machine Gun Blows, giving Garou a tough go of it. Garou retaliates with his Flowing Water Rock Smashing Fist, but Genos ducks and strikes him with a punch thats propelled by a booster integrated in his elbow. Garou intercepts the attack, then counters with a left knee to Genos' head. The attack sends Genos into the ground, and Garou prepare to land the final blow. However, Genos fires an incineration blast, to which Garou just barely manages to evade. Genos gets back up by thrusting himself upward with turbines built on his back, and he intently observes and analyzes Garou's movements. Genos tells Garou to surrender, as Garou's legs are about to give out, but instead, Garou jumps up into the trees and changes his movements to mimic that of Watchdog Man. Genos is momentarily caught off guard by this change of battle style, and Garou uses this moment to rip off Genos' right arm. Alas, Genos arm is still operational, and the right arm grabs Garou's neck. The arm uses its rocket propeller and slams Garou into a tree, using wires to trap Garou in the process. Genos than taunts Garou that he is just a thug not a serious threat to be the worth the time to take care of unlike the Monster Association. As Genos lifts his arm and prepares to fire his incineration blast, but Garou pushes his legs onto the tree and breaks it apart, saving himself from the incineration blast. He then jumps into the roof of the shred and proclaims that the Hero Association doesn't need to look no further since he is the most powerful monster right here and he is not some common thug.

Genos prepares another attack, but from the ground, a horde of monsters tunnels out of the ground and simultaneously attack Genos to protect Garou, but the monsters are all swiftly defeated. A flower monster appears behind Garou telling him that the Monster Association has recognized his talent and want to recruit him into their rank as one of the top executive member. However, due to Garou's lone wolf nature, he coldly rejects the offer and tells the monster to get out of his sight. The monster then try to forcefully capture him to join their rank because of its order from the Monster Association but being bisected by Genos's arm-blade. After taking care of the monsters, Genos proclaims that he cannot being defeated by a surprise attack like this and he has to follow the teaching of Saitama to become stronger by training both mind and body. As the result, Garou then questions Genos about Saitama in which he proudly states that Saitama is the mightiest hero that no monsters can hope to surpass. For the third time, Genos readies his incineration cannon, but this time, the one to intervene is none other then Bang and Bomb. Genos is surprised to see them both present, and he proceeds to do battle with the other monsters still flooding out of the hole in the ground. While Bomb and Genos fight off the monsters, Bang stands hovering over Garou, admonishing his weakened and abominable state, and tells Garou to stand up and fight him. Garou does as his former master says, and the two of them ready their stances. Garou lunges for Bang and attempts to attack him with the Flowing Water Rock Streaming Fist, but before he even has time to react, Garou is viciously pummeled by Bang.

As he is pummeled rapidly by Bang, Garou tries to counter-attack against his former teacher but his efforts are in vain due to his weakened state and their difference in Water Stream Rock Smashing Fist mastery. He ends up continued to be overwhelmed. Knowing that he cannot win, he attempts to escape and uses Death Gatling's unconscious body as meat shield to cover his escape. However, Bomb intercepts him and kicks him in the face toward the group of remaining monsters, causing the monsters to be shredded by Bomb's razor sharp Whirlwind Iron Cutting Fist. Afterwards, Bomb and Bang combine their martial arts against Garou. In the state of great pain, Garou remembers his miserable past as a misunderstood child being bullied. In the his anger and despair, he commences a counterattack with Tanktop Master's Tanktop Blow and grabs a huge tree during the confusion, and then swings at both Bomb and Bang making them to back off. Phoenix Man suddenly appears and creates immense air pressure that launches everyone and proceeds to grab Garou in the air while calling for Elder Centipede to cover their escape. Despite Garou's protest, he cannot do anything against Phoenix Man as he is being escorted to the Monster Association HQ.

After being rescued by the Monster Association, Garou saw the association has captured Narinki's Private Squad to be put on trial and the unexpected recruitment of a mysterious G5. During the trial, a voice in his head, presumably Psykos tells him to remain low profile until the trial is over. Once the trial is over, with Do-S takes it to brainwashed the captured Private Squad for the Monster Association’s usefulness, Royal Ripper sense Garou’s scent and tells him to now to reveal himself. Later, Garou speaks with Gyoro Gyoro and the rest of the association’s members, as well as its leader Orochi, who promotes Garou as one of the executive member of the association and send him to murder a hero in one day without hesitation in order to prove that he is a real monster. Unaware to Garou, Gyoro sends Royal Ripper and Bug God to keep an eye on Garou, in case should he fail.

A new group agrees with the monster outbreak. They attempt to capture a citizen for disagreeing with their ideology, but bump into Garou. Unfortunately for them, Garou knocks them out with a flick before heading to a nearby restaurant. Garou eats everything on the menu, before dashing out. Later, Garou scares some boys who were bullying Tareo. Tareo thanks Garou for his heroism, to which Garou is disgusted by. Soon enough Saitama catches up to Garou and let's Garou off with a warning. This severely angers Garou, thinking that heroes have starting to take pity on him. He resolves to carrying out his task by bring back Saitama's head, but Saitama accidentally punches Garou, knocking him out. Some time later, Garou wakes up and asks Tareo who the hero was. Immediately after, Bug God and Royal Ripper confront Garou for not seeming like a monster. Royal Ripper approaches Tareo, to which Garou tells him to back off. Garou is seen assuming a stance in front of Tareo and forming a fist as Bug God and Royal Ripper approach the pair. Royal Ripper reveals that Gyoro Gyoro had sent him and Bug God to follow and monitor Garou. After observing his behavior, they now have doubts about Garou’s intent, questioning whether if he is a true monster or not. Garou then proceeds to provoke Royal Ripper to little use, as the latter then demands the former to kill Tareo. Garou then inquiries about the reasoning behind the request, to which Bug God replies that one must leave behind what makes them human in order to qualify as a monster. Royal Ripper reaffirms this statement and continues, adding the fact that Garou might not be the best candidate after being defeated by Saitama. Garou then proceeds to tell Tareo to go home, but he was unable to do so because of fear. Due to this, Tareo is berated by Garou, who then forces the hero catalogue out of his hand, saying that the boy needs to get stronger during times like these. While doing so, Royal Ripper attacks Tareo. The attack is quickly stopped by Garou, who hoisted Royal Ripper up in the air by his blades and swiftly delivered a kick to his opponent’s abdomen. Royal Ripper then flies into the air as a result, but is quick to get back on his feet by thrusting his blades onto the ground and perform a somersault with the two blades acting as anchoring points. The move severely disfigured his arms, but Royal Ripper restores his limbs back to their original state by twisting them back. Then, Garou yells at Tareo, telling him to run. The boy complies and is seen dashing away. As he is doing so, Royal Ripper announces Garou to be an enemy. Garou then assumes a stance as the two monsters charge at him.

As the two monsters charged, Garou delivers a punch towards Bug God’s torso. Unfortunately, this injures his own hand. Royal Ripper then performs a chain of frenzied slashes aimed at Garou, but they are all dodged or reflected. As Garou is busy with Royal Ripper’s chain of attacks, Bug God approaches him from behind, but is bombarded with a flurry of deflected slashes originating from Royal Ripper. The monster is undeterred by this as he quickly pounds Garou into the ground and then flinging him onto electric cables, which briefly electrocutes Garou. Garou immediately rebounds himself towards the two monsters as they leap towards him. The three eventually enter a stalemate, with Garou now confident in his abilities to defeat his opponents, while the pair of monsters declaring to go all out. Garou is not discouraged by this, even going on to say that he has seen everything they have to offer and will not be hit by them again. It then transpires that Tareo was captured by Sludge Jellyfish. Garou is briefly distracted by this occurrence, so Royal Ripper brutally slashes him in the back and subsequently struck in the torso by Bug God before ultimately being assailed with a series of slashes leaving him in a pool of blood. Bug God quickly puts a stop to the assault, explaining that Garou should be left alive. Royal Ripper ceases attacking, but declares that it might be too late for Garou. He then invites Tareo back home with an eerie grin, saying that they will be great friends.

After a while, Garou wakes up and is perplexed upon what happened at first before recalling fighting and being defeated by Royal Ripper and Bug God. He also realizes that Tareo was kidnapped by the monsters but brushes it aside while wondering how he managed to heal himself. Upon recovering, Garou then proceeds to the Monster Association HQ while also seemingly undergoing a change in his body. Much later, Garou breaks into the facility just in time to save Tareo from Royal Ripper. Despite being stabbed in the gut by the monster, Garou punched Royal Ripper's head off with one blow, killing him in the process, before using the Whirlwind Iron Cutting Fist to shred the monster to pieces. He and Tareo then make their escape only to encounter two monsters who were quickly dispatched by Garou. The Hero Hunter devours one of the limbs of the monsters to replenish himself before proceeding with Tareo. As they make their escape, Tareo tells him that there is another child that is in need of rescuing but that's not Garou's concern and he did not come here to save Tareo, either. However, before the two can continue, they are confronted by Overgrown Rover.

Original Webcomic
While Garou managed to keep the kid from dying, the two of them got separated when Garou smashed Overgrown Rover through the ground while telling it to sit.

Garou later confronts Psykos and manages to out maneuver all of her psychic powers at first, but when she told Garou that the Monster Association is going to find and kill the Busaiku, he lost focus and got crushed underneath increased psychic gravity and was left unconscious.

Later, through unknown means, Garou had encountered and defeated Puri-Puri-Prisoner in one blow, while seemingly having started transforming into a monstrous version of himself. He then hides and observes as Superalloy Darkshine finds the beaten S-Class hero and promises to beat Garou down for him.

Garou and Superalloy Darkshine begin fighting each other. Darkshine eventually launches a full force tackle at Garou, who tried to deflect it with the Water Stream Rock Smashing Fist, but the hero's attack had so much power behind it that it broke through the deflection attempt and shattered Garou's rib cage. Darkshine told Garou that his "monster play" is now over, to which Garou, who seemed to be unphased by his broken ribs, accused Darkshine of "playing hero" before explaining why he hates heroes. Garou then unleashed a flurry of attacks that kept increasing in speed and power and frightening Darkshine. Darkshine eventually countered with a full strength punch, which Garou, with his sudden increase in strength, just catches in one hand. Garou eventually beats Darkshine out cold when Tatsumaki had started tearing the entire Monster Association building out from underground.

Garou is later seen wandering around the wreckage of the Monster Association building, finally feeling the full effect of the injuries he had received and wonders to himself if this is the way he actually wanted to die.

Garou then approached Fubuki after she had defeated Psykos; at this point, Garou had seemed to have almost finished transforming into a monster and stated that he is a Disaster Level of God. Garou then tore through all of Fubuki's attacks while demanding that she tell him what he looks like.

Garou later arrived at the final battlefield of the S-Class Heroes versus the Dragon Level Monsters.

Garou ripped One Hundred Cell Black Sperm in half, reducing him to a single cell, in order to get him away from the Busaiku, he then punched Golden Sperm in the face with enough force to flatten his face temporarily, before he simply healed.

Garou then ordered the Busaiku to watch as he "Changed his view on heroes".

Garou and Golden Sperm then had a battle that was too fast for any of the heroes present to follow with the end of said fight resulted in the death of Golden Sperm, and Garou having completed his transformation into a monster.

Garou then had a long battle with all of the present heroes and seemed to defeat them all with very little effort on his part, all the while stating that he was going to kill the Busaiku if none of them could stop him. Saitama then stepped in to fight Garou.

Garou then fights Saitama and, despite his best efforts, cannot defeat the Caped Baldy. Saitama not only beats him physically but mentally as he forces him to realize that he never wanted to be a villain, but a hero. Saitama comes to this conclusion because, despite being easily able to do so, Garou did not kill any of the heroes that he fought, as well as the fact that Garou stated that he wanted to create world peace through people's fear and hatred of "Garou the monster".

Many of the present heroes had gotten back up by this point and demanded that Saitama kill Garou, but the Caped Baldy refused their request, stating that Garou was still human.

The other heroes then decided to just kill Garou themselves, only for Bang to step in and start beating Garou while scolding him for choosing the path in life that he did, although it is clear that his attacks are not meant to actually kill Garou, so Sweet Mask stepped in and decided to kill Garou himself.

The Busaiku then ran in and demanded that Sweet Mask stop, since Garou had saved his life twice, while the heroes couldn't even save him once.

Garou is eventually convinced to continue living and runs away. However, he was so fast that only Saitama was able to see where he actually went. His current status and whereabouts are unknown as of this time.

Trivia

 * Sometime later after beating 19 heroes, Garou hunts an A-Class hero named Death Gatling. The Hero Association has been monitoring him and the area is cleared. After blocking bullets from Death Gatling, Garou is blasted by Genos' laser attack. Genos and Garou proceed to battle with Garou dodging Genos' attacks. Then Garou is attacked from behind by his old master Bang and Bomb. The two of them beat Garou to within an inch of his life and Garou remembers why he decided to become a monster. Before he can continue the fight, Garou is rescued by four monsters from the Monster Association.
