Monster Raid Arc
Zakos is participating in the Martial Arts Tournament in C-City at the the C-City Super Stadium. This is the seventh time in a row Zakos has participated in the tournament. Zakos wishes to win so that he can propose.

Saitama 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 foward to the match as well and will beat Saitama to a pulp.

Quotes
"Even the man they call the greatest treasure of martial arts is getting old, it seems... He's abandoned the dojo and the tournament for some so-called hero activities like he's living in his own dream world."
