I love these antiheroes. The first one is Conan the barbarian from my childhood.
The second is Rorschach of Watchmen.
Third one is a god but not like the spoilt child of Olympus, Zeus :) He is Odin of Asgard. He knows that he will go to Valhalla at the end. To me, the most impressive thing about Odin is he sacrified one of his eyes to drink the Mimir's water which gave him the wisdom of ages.
And the last but not the least: Behzat Ç. of Ankara :) He is a pure antihero for sure.
