Can't really say I have a hero. Superman used to be my hero as a kid, and I've seen some extremely inspirational writing for characters in several anime series, but fictional characters can't really be heroes, now, can they?
I used to be a fanatic of Pentti Linkola, and while I still subscribe to his idea(l)s, he's no more a hero to me than I am. Ohoo, there's a thought: I am my own hero.
I admire people who get things done, though. Maybe such people are my heroes? But that doesn't include me...
Meh ¯\(ツ)/¯
