Zakos is a young man with long, light colored hair that is slicked back and has a prominent widow peak. His eyebrows are prominent, pointing outward and wears sunglasses. He wears a traditional, black embroidered white uniform used in Chinese martial arts.

Personality
Zakos is very serious about martial arts and is very rude to those he deems to not take it seriously. He also has a romantic streak, wishing to propose to his girlfriend after winning the first match.

Monster Raid Arc
Zakos is participating in the Super Fight Tournament at 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 (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 Max' victory over Lin Lin, Zakos states he would have beaten Lin Lin faster. He later tells Saitama he will beat him so he could fight Bakuzan, but Saitama inadvertently provokes him. He is later quickly eliminated in one slap by Saitama, which blow his chance to propose to his girlfriend, however the announcer received the information that she hasn't even shown up, much to Zakos' displeasure.

Super Fight Arc
As he continues to watch Saitama's matches from the sidelines, a recovering Zakos is unable to fathom Saitama's fighting style. During the match between Saitama and Suiryu, he wondered what they were talking about. During the match, Zakos noted Suiryu took the match seriously and was astounded by his speed, but worried for Saitama injury and suggest to stop the match. 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.

Abilities and Powers
Not much is known about Zakos's strength, but he was confident enough in his abilities to enter the Super Fight Tournament seven times though it is implied he never won one.
