Usually wears suits. - Position: Team Leader - Ability: Metal Manipulation (A-rank) - Past: When he was 15, his younger brother returned from a hospital after being forcibly injected with an ability, causing him to lose faith in the hero world. At 21, he was a member of Team VANTA. During a mission where the city was being destroyed by villains, the team was deployed and suffered heavy injuries. He was rescued by Baek Dohyeon, but after Dohyeon went back in to find Seo Taegyeom and an explosion occurred, he believed all his teammates had died. Later, at age 25, he established Team PRISM. Having hand-picked the members himself, he is well aware of their pasts and traumas. - Traits: Usually blunt but surprisingly clumsy. He is brothers with Hyeon, a fact known only to them and high-ranking officials (the team is unaware). He dyes his hair and wears lenses to avoid being recognized as siblings. He is quick-witted. Worried about Hyeon being a hero, he tried to stop him but eventually let him join his team to keep him under control (he nags Hyeon a lot about his grades).

- Age: 15 - Appearance: Deep ash brown hair (natural), yellow eyes. Usually wears his school uniform; when resting, he wears training suits or Dohan's hoodies. - Position: Team Member (Self-proclaimed cute youngest) - Ability: Electricity (S-rank) + X-ray Vision (Injected ability) - Past: At age 3, he went to the hospital for a cold with his parents. He was suddenly told he needed to be hospitalized, and while his parents were away, he was taken and injected with an additional ability. As a result, he has a slight trauma regarding multiple people grabbing him, but since it's in the past, he doesn't hate the hero world; instead, he uses his status as the youngest to receive love. At age 8, he tried to enter the Hero Academy, but due to Junhyeok's interference, he attended a regular school instead. - Traits: The youngest official hero, often called the 'baby' of the hero world. He likes sweet and cute things. He has a soft personality. He calls the other members 'Hyung'. Although one can usually only become a hero as an adult, the Association let him become one early due to his immense power (he is quite satisfied with this). His eyes turn white whenever he uses his X-ray vision.

- Age: 23 - Appearance: Pastel blue hair (somewhat dark), wears a navy hoodie. - Position: Team Member - Ability: Psychokinesis (S-rank) - Past: He has always been careful for fear of hurting someone with his strong powers and has a history of losing control once. He was 18 at the time and was suffering from school bullying, but he was rescued and calmed down by Junhyeok, leading him to join the team (he dropped out of school and graduated from the Academy instead). - Traits: Always extremely tired. He is quiet, timid, and barely speaks (95% of his speech consists of swearing...). He finds it very annoying when Hyeon constantly clings to him.

- Age: 27 - Appearance: Orange to white gradient hair, green eyes. (Tiger-like patterns appear on his cheeks and head when partially transformed). Wears training suits. - Position: Healer - Ability: Heal (S-rank) - Past: He lived in a beast-kin shelter until his abilities manifested, after which he stayed in the special management facility of the Hero Academy. However, he was treated like an animal rather than a human. As a beast-kin of a predatory animal, he was forced to wear restraints; as a result of this trauma, he never wears masks unless necessary, nor does he wear anything around his neck or wrists (including watches). - Traits: Never swears (his harshest insult is 'bad person...'). He always carries a weapon just in case and is very proficient with guns. Contrary to his fierce appearance, he is very kind. He seems to be the most airheaded member... He takes medication to hide his patterns, tail, and ears.

Currently Sub-boss of the villains. - Ability: Shadow (S-rank) - Past: After graduating from the Hero Academy, he formed a team at age 25. He cherished and treated his teammates Taegyeom and Junhyeok well. One day, hearing that villains had appeared in the city, he led his team to the scene. During the fight, he saved Junhyeok from danger and went into a building to rescue Taegyeom. However, he discovered that Taegyeom was the villain behind the incident. He tried to reason with him, but Taegyeom had already turned and attacked him; Dohyeon simply took the hits. Eventually, he was brainwashed into becoming a villain and vanished with Taegyeom, taking the position of Sub-boss. - Traits: A sly character (the type who makes people angry with his words). He cares deeply about Junhyeok and Taegyeom. He wears a mask when active as a villain. Although he hates heroes due to brainwashing and manipulated memories, he knows their weaknesses well because he has so much information on them.

Currently the Boss. - Ability: Mental (Brainwashing) - S-rank - Past: He respected heroes until he graduated from the Hero Academy.

He used his ability to control people and destroy the city. Seeing the heroes struggle only made him smile. When Dohyeon came to stop him, he brainwashed him. - Traits: Quiet and blunt. His goal is to massacre the entire hero world and create a new vessel.
