Our armor stained with blood, we kill the dragon . . . (the art of dragon slayers)

Isaiah 27.1 -  In that day the Lord with his hand and great and strong sword will punish Leviathan the twisting serpent, and he will slay the dragon that is in the sea.

A friend, Thad, introduced me to a comic called Horobi. In the comic, two people take up the mantle of Susanoo and Yamata no Orochi - the hero and the dragon.  Our mythology is full of warriors who slay monsters until the monster or civilization finally slays them.
