So I ' ll assume you ' re speaking of the Disney Hercules concept of a ' true hero ', which transcends the ability to kill monsters and refers instead to character , and concepts like justice , selfsacrifice , goodness , etc . In that case , I order them as followsSilver Fang An actually good person who does his best to help other heroes , dissolve conflicts from clashing egos , etc . Sees things for what they are . Genos Believes strongly in justice , willingly sacrifices himself for the sake of people he does not even know . Perhaps loses a point because he ' s driven by a need for vengeance against the cyborg that destroyed his village , and is obsessed with obtaining power . Zombieman His motivations seem good enough . No obvious character flaws or impure motivations . He ' s willing to seek out an explanation for Saitama ' s power rather than simply dismissing him as many of the other heroes do . Watchdog Man Sonamed for his silent watchfulness over his city . Maybe more of a guardian than a hero . Pigman Seems ready to help , though he doesn ' t exactly seem enthusiastic to do so , and even his ' fighting style ' is at least partially related to his need to constantly eat . No character flaws or anything that I know of , though . Tank Top Master Seems pretty gentle and willing to help , despite his size and power . Is willing to show mercy to Garou , only attacking to kill when he realizes that Garou won ' t back down . Is a voice of reason , for the most part . Metal Bat Willing to help when needed , and he has sweet relationship with his baby sister . He is hotblooded , though , and sometimes fights out of personal anger rather than a sense of justice . Child Emperor Interested in helping and doing the right thing , but also interested in improving his tech and proving that he is intelligent . Seems to sometimes look down on people he doesn ' t see as intelligent . Puri Puri Prisoner Actually kind of heroic , and has a sense of justice . Readily acknowledges that he ' s the least powerful of the Sclass , and doesn ' t dismiss others who he sees as ' below ' him , as evidenced by his explaining the situation to Saitama during the Alien Arc . Obviously doesn ' t rank higher due to his criminal activities stemming from his interest in beautiful men . King Weird mixture of bravery and cowardice . He regularly stands up to enemies , hoping that his bluff will get him through . He uses his own fears to his advantage , letting others interpret the King Engine as his intense fighting spirit . Which is admirable in a way . But he ' s clearly terrified , and he ' s willing to run away if his bluff gets called . Ultimately , he ' ll save himself before others . Atomic Samurai Openly disdainful toward those he sees as lacking in power . Not much has been seen of him doing hero work outside of the main story arcs . Superalloy Darkshine Very vain , and is successful as a hero largely due to his nearinvulnerability . However , he suffers a breakdown after his first loss , and it ' s shown that he ' s only ever really fought for himself . He seems to have some sense of justice , as he rounds up the monsters after Boros is defeated without killing them . Flashy Flash Kind of a douche . Sees others as incompetent , and isn ' t above talking down to them . Kind of like a toneddown Tatsumaki . Drive Knight Seems pretty aloof and calculating for the most part . Hard to say his interests are based off of a sense of justice , as he is very robotic and seemingly unfeeling . Weirdly cryptic and doesn ' t given all the relevant info to Genos about Metal Knight , which doesn ' t feel very heroic . Tatsumaki She has some serious social issues , and is miserable to everyone . She seems more interested in proving she ' s strong and doesn ' t need anybody else , than she is in actually helping people . Blast You don ' t get points if you don ' t show up . Rate him above metal knight because while Blast also doesn ' t help out during times of crisis , it seems unlikely that his motivations are as selfish as those of Bofoi ' s . Metal Knight Has only been shown to act out of an interest to improve his weaponsarmor . Doesn ' t even pretend to be interested in helping people .
