This is a Black Knight from Dark Souls. What I like about this character is how the armour he wears keeps him shadowed in dark locations, making him almost impossible to see. I want to implement this into my boss, as it will create a very interesting scene of the player trying to find the boss through the darkness, and then having the boss emerge and attack the player before retreating.
