Gregory Brigham is a Major in the British SAS and a Champion in the Fourth Great Games of the Hydra.
Greg Brigham exceled in the first two stages of the great games, winning both and giving the same wish. The wish for his next highest opponent's head to be blown off. He gets thrown of the back of his LSV in the race challenge. He ultimately gets killed when Zaitan destroys him with Mephisto's flail and kicks him into the well hole in the centre of the arena.
- Brigham was the only one to win more than one challenge.
