>superheroes are creatures/concepts as old as stories though, from the oldest myths of Ulysse

Ancient/Mythical "heroes" are not like our modern superheroes which are kind of a mix of gods/demigods and christian saints. Superheroes are people with superpowers plus a drive of serving justice, helping the weak, protecting mankind, etc. Plus always ready to sacrifice themselves for others. Classical heroes range from purely self-motivated (Ulysses), selfish and self-serving (Achiles) to literal assholes (Gilgamesh). Achiles values are very similar of former-gangster rap stars (or at least the characters they built of themselves). Fighting is most important. Only fights for himself and his glory. Top dog of his culture. Has a particular sense of fairness in regard to his own selfishness.
