He's dark and powerful with only his tone, sounding much like Mark but with the added reverb and effects and such. Videos of his portrayal on Youtube highlight how he sounds. A male voice is needed, along with the right effects, otherwise it's debatable. He's a social manipulator that only uses people to make his way further or to achieve his own needs, coming off as comforting and eerie all at once. He only wants whats best for you, in return for your undying devotion to his every will and command. It's all an act, don't play his game.
