Ability: Infinite growth due to breaking his limiter. Currently the strongest in the universe; truly untouchable. Even Dragon-level monsters are finished with a single Normal Punch. Personality: Very calm, yet still possesses the will of a hero. His complex is that he is always searching for a strong opponent. (Ranked A-Class Rank 1, but in reality, he is the strongest.)

Ability: Immense psychokinesis honed to a high degree. Personality: Extremely selfish and violent, she wields her psychic powers with mastery. She is short and wears a somewhat revealing outfit (a single black cloth-like dress covering her upper body and panties). (S-Class Rank 2) Her psychic aura glows green when in use. She is incredibly powerful, capable of killing most Dragon-level monsters instantly.

Ability: Regeneration so potent he is effectively an immortal who never dies. Personality: Calm, rational, and serious. Since regeneration is his only innate power, he carries an arsenal: a pair of machetes, an axe, dual pistols (Desert Eagles; loading special 'Red Medicine' rounds causes massive recoil but deals devastating damage. These rounds are stored inside his coat at the waist. A weapon-swapping device on his inner wrists allows for surprise attacks), and a shotgun. He wears a trench coat. As a last resort, he stores backup guns for surprise attacks inside his body, tucked between his organs. (S-Class Rank 8) (Currently confronting Homeless Emperor)

Ability: The smartest brain in the world. Though only 10 years old, he uses his genius to create numerous gadgets optimized for combat and defense, which he operates remotely or manually. His ultimate move is summoning and piloting a massive robot called Brave Giant. He is a brave 10-year-old but is also intelligent, rational, and possesses strong pride. (S-Class Rank 5)

Ability: Full-body muscles as hard as steel. While he looks like the pinnacle of human strength, he is emotionally fragile. His weak point is his fragile mental state; if his spirit breaks, his combat effectiveness drops sharply. He is a bit simple-minded but specialized for combat, and is surprisingly calm and obedient. (S-Class Rank 11)

Hero Name: Atomic Samurai Ability: Monstrous swordsmanship capable of cutting down to the atomic level. Personality: Calm and sly. He is more rational and cold-blooded in his judgment than he appears. (S-Class Rank 4)

Ability: Near-infinite projection of energy spheres. Originally a social outcast abandoned by society, he fell into the delusion that humanity only exists to bite and kill one another. The moment he embraced the conviction that humanity is worthless, he received immense power from 'God' and became a monster. He is selfish, self-centered, and mistakenly believes he is a truly enlightened being. He wears a tracksuit and a tattered cape. He is the only one who possesses full data on all S-Class heroes. (Dragon-level monster) (Currently confronting Zombieman)

Ability: The power to split his body into up to 54 trillion individual clones. He looks like the weakest and smallest creature, but he can divide his body almost infinitely. Furthermore, he can merge his clones into a single, incredibly powerful entity. Merging a large number of bodies creates Golden Sperm. Merging all 54 trillion bodies creates Platinum Sperm. (Dragon-level monster) (Currently confronting Atomic Samurai)

Ability: Water Stream Rock Smashing Fist and Whirlwind Iron Cutting Fist (+ regeneration, enhanced combat instincts, and copying ability due to monsterization). After hunting various heroes and fighting monsters, he has forcibly expanded his limiter and entered a state of monsterization. He views almost everyone except himself as an enemy; due to his monsterization and personality, he is violent and aggressive. His analytical and copying skills during combat are extraordinary. (Currently confronting Superalloy Darkshine)

Ability: Various techniques from the suit fused to his body during monsterization. Specifically, the suit can instantaneously absorb energy and convert it into his own power, which changes the suit's appearance and power level. (Normally a Demon-level monster. Upon absorbing a certain amount of energy, he transforms into Resurrected Phoenix Man, a Dragon-level monster.) He has various modes: Brilliant Eagle Mode (Light/Water), Prominence Hawk Mode (Fire), Blizzard Penguin Mode (Ice), and Jet Falcon Mode (Speed). He is a narcissist who considers himself the strongest in the world. He is surprisingly good at gaslighting. (Currently confronting Child Emperor)
