How can this iconic Guild Wars race get any cooler? Their pseudo-leader is named Smodur the Unflinching. They are badass. Possibly one of the most badass fantasy/sci-fi races ever created, especially on the protagonist side. Take the hardness and grimness of Sparta, the structure and purpose of Ancient Rome, and make them anthropomorphic, meat-eating predators.
I remember an old Ang Lee interview where the director talked about making the movie Hulk where he really wanted to play up that childish impulse to just smash things recklessly. It plays to our id, if you will, that we usually repress so we can have nice things and bigger wallets. The charr are the Guild Wars 2 race that call to similar primal instincts to dominate, to bully, and to win at any possible costs. Hey look, Guild Wars 2 is also a PvP game that will attract PvP players.
