“The history I imagined for this character is that he is from a race of great warriors; you could imagine him on a huge battlefield in the first line of fire. He can be a nice combat mate, but he’s brutal too. He has a deep sense of honour and respect for the enemy, but he can kick ass if he wants to.”
