Gyoro Gyoro

Gyoro Gyoro (ギョロギョロ, Gyorogyoro) is a Mysterious Being of the Monster Association acting as Orochi's closest advisor. It is one of the main antagonists of the Monster Raid, Super Fight and Monster Association arcs.

Appearance
Gyoro Gyoro appears as a large slug-like monster with a single eye, with no visible facial orifice and eight arms protruding through its head. It has four main arms, stubby legs, three toe feet, and a fat circular body.

Personality
Gyoro 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 her 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 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 falsly lead the officials with an ideal of 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.

History
After countless failures and sacrifices, Gyoro Gyoro created the human turned monster Orochi. Through a special nurturing process, Gyoro Gyoro stimulated the growth in the human and made them into a monster.

Several years ago after Orochi defeated Gouketsu, Orochi and Gyoro Gyoro offered Gouketsu to help the martial artist gain more power in exchange for cooperation.

Super Fight Arc
Gyoro Gyoro is speaking with Monster King Orochi about the monster raid's situation and Gouketsu whereabouts.

After Tatsumaki killed the Hundred-Eyes Octopus, Gyoro Gyoro finds the situation troublesome, but Orochi sees it as not a concern because they can make as many Mysterious Beings as they please.

Through his robot, Metal Knight questions Orochi and Gyoro Gyoro about their goals. While they tell him destruction is a natural part of a monster's instincts, it is not their end goal.

Gyoro Gyoro denies Phoenix Man's request to reinforce the cornered monsters and order Gouketsu to return from the C-City Super Stadium.

Monster Association Arc
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. It briefly pretends that the Monster Association's goal is merely to live in peace and be free from the threat of elimination. However, when an 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.

It 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 its drones, it sees Gouketsu's headless corpse.

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. Afterwards, 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.

Abilities and Powers
It's currently unknown what the full extent of Gyoro Gyoro's powers are but as it is serving under Orochi directly it may be that the "Monster King" has high faith in Gyoro Gyoro's abilities unlike the others members.

Supernatural Abilities
Spy Drones: Gyoro Gyoro has several spy drones that is shaped in its image and can communicate through them along with seeing things outside his line of vision.

Telepathy (テレパシー, Terepashī): Gyoro Gyoro uses telepathy to sometimes communicate with others. Gyoro Gyoro has used telepathy to tell Garou to wait while sorting out disputes among the monsters.

Monster Transformation Stimulation: Gyoro Gyoro claims that it can stimulate growth in human beings and turn some of them into exceptionally powerful monsters, like in the case of Orochi. Gyoro Gyoro's method is unknown in detail, but it can be assumed to be similar to the phenomenon of abnormal cellular reactions that normally transform some humans into monsters, without the Monster Cell.
