Father Grigori (AKA Crazy pensioner with a rifle) is a psychotic priest who is found in one chapter of Half Life 2, because no one could stand to deal with him for more than one chapter. He thinks he is doing the right thing by executing his former neighbors one by one through the use of buzz saws, rotating blades, and gas barrels. Known for cackling mainly whist killing zombies, he never seems to stop bitching about how he is doing the zombies a favor, and how he could not think less of them. What an asshole.
