Katsugi Mozumo, otherwise known as the Freelancer, is the protagonist of the fanon story, The Hero Without A Name! Considered to be the strongest hero of his generation, Katsugi is an X-Rated Prisoner from the maximum security facility, Maggot's Nest, a lawless prison with only the Law of the Jungle as the only rule. While not on the same level as Saitama, the protagonist of the canon story, who is capable of defeating any foe he meets with a single strike, he is capable of defeating many strong opponents. He is, essentially, this story's version of Saitama.
