Genus created Carnage Kabuto, a mutant beetle. He is the House of Evolution’s most powerful creature. Also, He is a vile and cruel being. He hates Genus, his creator. This is because he believes he is the perfect being to replace humans.

In Addition, He is a strong believer in independence and will kill anyone who gets in his way during his temper tantrums. He is particularly interested in fighters described as being very strong. Also, He shows his fear of anyone with a greater power than his during his encounter with Saitama.

Saitama was an idiot and he started to underestimate him, until he lost the terror he felt earlier. Professor Genus first mentions Carnage Kabuto. This is the one who confronts Saitama.

Scaravageur pulverizes the clone, despite his pleas to not approach it. The real Genus approaches him and asks if he is done letting off steam. Carnage Kabuto approaches him and says that he feels outraged at being imprisoned when he is the most powerful product of House of Evolution.

Professor Genus tells him that he does this because he’s out of control. Because it doesn’t want to be controlled, the insect laughs. He is a perfect creature, and nothing can surpass him.

He can get angry if his opponent exceeds his abilities or proves disappointing to him. SuperAlloy Darkshine is, at his core, a selfish hero who seeks glory more than a challenge. His greatest desire is to win a tough fight that will make him feel better about himself.

He would be among the strongest, if not the most powerful.

In a titanic battle, he fought Saitama and lost his life. Boros is a raven-blue color with one eye. However, when he becomes serious, he turns to white and is more powerful than Saitama when calm.

Although Saitama might not have used even one hundredth of his capabilities, this opponent was the only one who was not killed on the first attempt. He was also able to stand in single combat with Saitama even though it was a one-sided encounter where he was not much hurt by the hero.

He uses the “Rain of Ordinary Blows”, which is the combination of several “One Punch” punches. It can also be used in “Serious Mode” against very powerful opponents. This has only happened once.

1. God – May Be Strongest One Punch Man Characters

God is a concept that some people believe in. According to Emperor Vanupieds, this being exists.

Morveduse invokes the name of God for the first-time. He relates how the lieutenants of The Association of Monsters seem like his creations. Emperor Vanupieds (a lieutenant from this association) recounts his encounters with God during the battle.

As Psykos tries to merge with Orochi, God appears to them as a huge brain mass. God would have then granted Psykos incredible energy power, giving him the ability of taking over Orochi and achieving his fusion.

She would then have been given the task of absorbing the entire world and annihilating it. It is now being questioned whether Emperor Vanupieds was captured by Zombiman in the fighting on the surface at the monster nest ruins.

The Zombiman is trying to get Emperor Vanupieds to explain who gave him his powers. He feels that the Heroes’ Association should be ready to face him as an enemy. Before Emperor Vanupieds could give a clear answer to his question, he heard something in his head telling him to stop.
