I recognize a (HF/BT guy (insert name here)) on the right, and and obviously captain DK (athras) on the left, but who is the dude in the middle?
That my good sir, is Diablo (in the circle).
Also, the figure on the right is actually Sarah Kerrigan, from the Starcraft Universe.
Sarah Louise Kerrigan, the self-styled Queen of Blades, is a major character and the predominant antagonist in Blizzard Entertainment's StarCraft series of video games and novels. The character was created by Chris Metzen and James Phinney, and her appearance was originally designed by Chris Metzen. Kerrigan is voiced by Glynnis Talken Campbell in the real-time strategy video game StarCraft and its expansion Brood War. The voice of Kerrigan will be played by Tricia Helfer in the upcoming game StarCraft II: Wings of Liberty.
