AppearanceEditGyoro Gyoro appears as a large slug-like monster with a single eye (colored red in the manga and blue in the anime), with no visible facial orifice and eight arms protruding through his head. He has four main arms, stubby legs, three toe feet, and a fat circular body, which is green in the manga and pink in the anime.
PersonalityEditGyoro Gyoro is shown to be very serious in its duties of aiding Orochi and very loyal to the "Monster King". Gyoro Gyoro is the only member of the Monster Association to speak of Orochi in high regard, formally calling him "Your Majesty". Unlike Orochi, who would nearly instantly kill a subordinate monster if they fail their mission, Gyoro Gyoro is shown to care more or at least value their fellow monsters as a spy drone was sent to warn Gouketsu to return or he might face real danger from the S-Class Heroes. This is further showcased when Gyoro Gyoro requested Orochi to spare Do-S as his unique ability might prove advantageous in the future war with the Hero Association. However like Orochi, Gyoro Gyoro also has a low tolerance for failure as when Orochi prepared to devour Awakened Cockroach for failing to kill Genos, Gyoro Gyoro merely proceeded to berate the defeated monster for returning after failing his mission. Gyoro Gyoro also shows this when he experimented on Garou to see if he has what it takes to be a monster and have him eliminated should he fail. Gyoro Gyoro doesn't like it when someone disturbs him during his meditation.
Gyoro Gyoro is shown to have a sadistic sense of humor. This is exemplified when Gyoro Gyoro delivered the message to the Hero Association and proceeded to falsely lead the officials with an ideal co-existence and harmony between humans and monsters. Gyoro Gyoro laughs at such an impossibility, proclaiming the idea of harmony between monsters and humans to be the height of humor for the Monster Association.
Gyoro Gyoro experimented countless different ways to break the limiter that holds back the growth of monsters. Out of all his methods, he found that sending one to the brink of death over and over again appears to be effective at doing this. Monsters he created this way grew powerful, but most of them died before reaching Disaster Level Dragon. Finally, he hit a breakthrough when he met a human Orochi. He said he knew of Orochi's dissatisfaction with the world and turned him into the Monster King.
Destrochloridium takes over the body of a Hero Association staff member and infiltrates the Hero Association with one of Gyoro Gyoro's drones to deliver a message to the Hero Association. He briefly pretends that the Monster Association's goal is merely to live in peace and be free from the threat of elimination. However, when a Hero Association staff member promises that they won't touch the Monster Association, Destrochloridium kills him, and Gyoro Gyoro reveals that they were just joking. The real message was that the Monster Association was declaring war and that they would give the HA 3 days to prepare. The hostage was only taken to ensure that the Hero Association couldn't ignore the challenge.
He gives a massive speech to the member of the Monster Association and witnesses Orochi eat Awakened Cockroach, as well as persuading Orochi to spare Do-S for her useful ability. Through his drones, he sees Gouketsu's headless corpse and is disturbed that someone could defeat one of their executive members.
Gyoro Gyoro leaves a message to Garou telling him rest within his cell. Later, Gyoro Gyoro was seen deciding on the fate of Narinki's Private Squad that attacked them. Gyoro Gyoro questioned G5 on how he found out about the Monster Association and answered the Machine God's question on attacking other monsters. Afterward, Gyoro Gyoro offered a deal to Garou to join the Monster Association as an executive member to help boost their forces after the loss of Elder Centipede and Gouketsu. When Garou left to kill a hero, Gyoro Gyoro ordered Royal Ripper and Bug God to tail Garou and watch his movements.
Phoenix Man later questioned Gyoro Gyoro on the purpose of sending combat types to observe Garou as both Royal Ripper and Bug God can decide to kill Garou on a whim. Gyoro Gyoro revealed that it was a test and to facilitate Garou's growth, stating that he needs to be ravaged both physically and mentally. Gyoro Gyoro, in particular, is excited to see what changes Garou will undergo as a result of experiencing monsters. Gyoro Gyoro reveals that Orochi was once a human that, after countless failures and sacrifices, became the ultimate being. Gyoro Gyoro created Orochi and that only it knows the secret trick of doing so. Gyoro Gyoro mentions that with the right nourishment, Garou has the potential of becoming a second Orochi, but that if he dies then he was never good enough.
During Royal Ripper and Bug God report about Garou, he sees through Ripper's lies and asks him to tell the truth in which Bug God tells what really happens during their fight with Garou. Afterward, Royal Ripper begins to question the fact that Garou was quite a formidable foe, which is why Gyoro Gyoro intentionally sent them after Garou since he knew both of them would turn on Garou and strong enough to potentially killed him. Gyoro Gyoro then asks whether he is dead in which both Royal Ripper and Bug God states that he surely dead, despite not checking on him carefully.
As he takes note of Tareo, he wonders who he is in which Royal Ripper states that he is his toy to play with or else he would have to cut someone else to quell out his blood lust. Consequently, Gyoro Gyoro angrily scolds him not to playing around since he had found the scouting robot used by Child Emperor to scout the Monster Association HQ and firmly stating that the S-class heroes are not to be taken lightly as he assumed that one of them executed Elder Centipede and Gouketsu as well as the fact he doesn't know the secret weapon, the Hero Association is hiding.
Later, when Garou takes a secret tunnel into the Monster Association base, Gyoro Gyoro immediately detects that there is an intruder. He only recognizes that the intruder is sending a biological signal, and is either a human or a monster. He sends monsters to Garou's location with orders to kill the intruder if it is a hero and welcome it if it is a monster.
Garou's rampage attracts Overgrown Rover, who assaults him and sends him crashing into Gyoro Gyoro's private room. Gyoro Gyoro is pleasantly surprised to see Garou alive, complimenting him for living up to his expectations and for growing so much stronger. He lifts the rubble off of Garou, but then forcefully restrains him. He asks Garou to have a quick talk.
Gyoro Gyoro tells Garou the secret of breaking the limiter as someone who must repeatably experience death and overcome it. He goes over his experiences and experiments to arrive at that answer and shows Orochi as his first success. He attempts to convince Garou to let him raise him into the most powerful monster, but he refuses. When Garou begins to adapt to the psychic restraint, he lets Orochi battle him. At some point, Gyoro Gyoro tells Rhino Wrestler that he has improved and became a Demon-level threat.
Gyoro Gyoro watches as the heroes strike team to attack the wave of monsters in the ghost town of Z-City. After the battle, he calls upon, Black Sperm, Nyan, Homeless Emperor, Gums, Orochi and Fuhrer Ugly for a talk.
During the Monster Association invasion, Gyoro Gyoro meets Tatsumaki at the Association main hub and both start to fight. Gyoro Gyoro goes for the offensive and releases an immense barrage of energy and rubble to crush Tatsumaki inside a condensed ball of concrete. However, his attack is ineffective as it is revealed that Tatsumaki was unfazed and he then proceeded to blow Gyoro Gyoro arm off. Impressed by Tatsumaki's esper powers, Gyoro Gyoro released his full power, becoming bigger and gaining many more eyes on his body. He then released a wave of 300x gravity on Tatsumaki, only for her to be unfazed. Angered, Gyoro Gyoro released a beam of energy that nearly vaporizes the Association main's hub but Tatsumaki walks out of it unfazed, then proceeds to crush Gyoro Gyoro's body effortlessly. Gyoro Gyoro admits that Tatsumaki's powers are much greater than he originally perceived but then complains that she finished him off so brutally. Tatsumaki asks him why he's complaining since meat puppets can't feel pain and then tells him that she'll force his body out of the puppet. Shocked by this, he calls for Orochi as an act of desperation and is shocked when Orochi doesn't show up. It is later revealed that Orochi encountered Saitama as Gyoro Gyoro then starts to beg for his life.
Gyoro Gyoro sends a spy drone to discover who attacked Orochi and finds Saitama. Not recognizing the hero, he describes him as bald who Tatsumaki interprets as Superalloy Darkshine. Tatsumaki levitates Gyoro Gyoro's devastated body and the monster attempts to attack the hero with energy beams but fails to do any damage. Tatsumaki pulls out a body from the monster.
Elsewhere, Fubuki senses her sisters psychic energy and is shocked at the level of power she is using.
Abilities and PowersEdit
While it's currently unknown what the full extent of Gyoro Gyoro's powers are, as a Disaster Level Dragon Mysterious Being and the direct military advisor to Orochi it is powerful enough that the "Monster King" has high faith in Gyoro Gyoro's abilities, unlike the other members. Prior to discovering Tatsumaki's true power, he believed he was more powerful than Tatsumaki; whom he had considered as one of the only four heroes able to defeat Elder Centipede.
