this question gets asked a lot here, huh.

normally i'd say data from star trek, but i already explained why i like him, so i'm gonna say socrates. he might have been a real person, but we only know him as a character in plato's writings and one play by xenophon, so i think i can put him down for this. and i find the idea of a random homeless guy who just walks up to people around athens and demonstrates at length that everything they espouse and believe in is a lie, to be kinda cool and funny. he also got executed for giving too many people existential dread, and was completely unafraid of death.
