One Punch Man: Monster King Orochi, Explained

In the One Punch Man manga, we were introduced to the terrifying Monster Association, an organization that works as the complete opposite and counter to the Hero Association. This organization seeks to bring monsters to the forefront of the world and to make them the rulers, destroying the Hero Association and all its heroes in the process. The very top brass members of the Monster Association, known as the Cadres, are Dragon Level threats and are considered to be the most powerful monsters that have been introduced in the story, with each one being strong enough to destroy entire cities.
