A small chat

Gyoro Gyoro is speaking with Monster King Orochi about the monster raid's situation and Gouketsu whereabouts.[2]

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.[3]

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.[4]

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