Major Zero

Major Zero, aka Corran. Is the mastermind behind the Patriots and the manipulator of the entire events of the Metal Gear series.

He is voiced by Rhys Darby. And helps Snake throughout MGQ3. Then triggers the Les Enfants Terribles project while Big Boss and Lance are in a Coma.

Like that guy from Batman said, "Sometimes you die a hero, or you live long enough to see yourself become the villain". This is certainly true for MGQ's version of Shiro and Major Zero.
