Sisyphus is the only Greek figure I can think of that's not cringe to ascribe to yourself. And that's only because nobody remembers the shit he did to get punished. The other tragic ones are either a humblebrag or concerning. Romulus and Remus are concerning. Enkidu is both, Gilgamesh is a straight up brag, as are the non-tragic Greek figures. All biblical prophets are (humble)brags. Norse gods are all brags, and saga heroes are mostly too obscure for me to know in detail.
I guess you could say Zacchaeus if you're short, or Goliath if you're really big. Oh wait, I guess going with physical things you could self-own with any monster.
