Personality

Unlike Orochi who would near instantly kill a subordinate monster if they fail their mission, Gyoro Gyoro is shown to care or at least value his fellow monsters more as he sent his spy drone to warn Gouketsu to return or he might face a real challenge from the S-Class Heroes. This is further showcased when he requested Orochi to spare Do-S as her unique ability might prove advantageous in the future war with the Hero Association. However like Orochi, He also has low tolerance for failure as when Orochi prepared to devour Awakened Cockroach for failing to kill Genos, Gyoro Gyoro merely proceed to berate the defeated monster for returning after failing his mission.

Gyoro Gyoro is also shown to have a sadistic sense of humor as when he set up the message to declare war on the Hero Association, He proceeded to toy with the officials with a false ideal of co-existence and harmony between humans and monsters before laughing as Destrochloridium shot an official in the head and proclaiming the idea of harmony between monsters and humans to be the height of humor for the Monster Association.

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 and while they tell him destruction is a natural part of a monster's instincts, but it is not their end goal.

Gyoro Gyoro denies Phoenix Man's request to reinforce cornered monsters and tells Gouketsu to return from the 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 the mercenaries 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.
