Waganma was confined in his prison cell when Royal Ripper brought Tareo along. Waganma mentions that he was captured the day before and that he was fed only bread and water. He expresses his hunger and quickly snatches a candy from Tareo and asks if he has any more food. Waganma comments on Tareo's uselessness and the monster's stupidity for capturing him as his father is an important figure to the Hero Association. Waganma knows then that the heroes will come save him and Tareo, although Waganma has safety comes first. Waganma recruits Tareo as Waganma's lackey in exchange for all the food Tareo receives.

Sludge Jellyfish goes to the cell where Tareo and Waganma are being held, and tells them there is no hope for either of them to be saved. Waganma disagrees, and says the Hero Association has plenty of heroes, and goes off to list the names of several heroes, such as Metal Bat and King. At the mention of King's name, Sludge Jellyfish becomes frightened, but confidently states the whole purpose of the Monster Association is to eliminate such heroes, and goes on to mention the Executive Members of the Monster Association, speaking in awe of their strength and remarking they must have been created by God. He states that there is no way humanity can win, and even King will fall.
