Saitama (disguised as Charanko) converses with Sour Face when Zakos appears and starts questioning Saitama. Sour Face ends up answering some of Zakos questions. Zakos then reveals that Bang was supposed to be one of the judges, much to Sour Face's surprise, and starts mocking the martial arts master. Sour Face starts to feel very insulted, but felt even angrier when "Charanko" did not seem angry at Zakos's comments. Saitama replies that he was not invested in the conversation and is only looking forward to fighting Zakos, but notes that Zakos doesn't seem strong. Zakos retorts by saying he looks forward to the match as well and will beat Saitama to a pulp.

After Suiryu continues to battle Saitama after he got disqualified for wearing a wig, Zakos comments Suiryu's murderous intent in his attacks.

Zakos was later present at the closing ceremony, when it was suddenly interrupted by The Three Crows and Gouketsu, who tells them they will become monsters. Zakos and the other martial artist were given a choice to become a monster or die, visibly frightened he was shocked to see some of the fighter accepting the offer. He later watched Suiryu fight the transformed martial artist's and was saved from Choze's energy ball attack. When Suiryu considered to become a monster, Zakos frighteningly watched, but was relieved that it was never his intention and cheered for Suiryu. Zakos was then knocked out by the crows with the rest of the martial artist.

He is later seen in the hospital with Sour Face watching the new about Monster Association.
