You might not instantly recognize the name D.C. Douglas, but you're almost certainly familiar with his voice if you've played Mass Effect 2/3 or Resident Evil 5. He's the friendly Geth known as Legion in the former and the not-so-friendly Umbrella stooge Albert Wesker in the latter. He's done with both characters now as far as he knows, and he's cooked up a cool mash-up video to bid them farewell (via Joystiq).
I mean, really... a Legion/Wesker union would probably not work out too well. The Geth may be a killing robot, but he's very familiar with the threat posed by the Reapers and their armies of zombie-like Husks. Wesker's love for B.O.W.s would probably put a strain on their partnership.
