Let's face it, the guy is Skeletor... or at least he tries to channel Skeletor through the bombastic, showy performance he puts on as a "human hunting fanatic". Though in truth, he is more enthusiastic than anything. Because he, more often than not, gets emotional or dramatic and occasionally makes snide remarks. As a result, this should be a very showy performance with highs and lows depending on the situation.
So... Imagine, if you will... The boosted voice of skeletor with the performance of a Monty Python skit.
