Nathan is a tough nut that's hard to crack. He's extremely broody and doesn't get along with most people. He finds almost everything annoying for one reason or another. He doesn't have a favorite anything, because everything ticks him off to some degree. He's the kind of guy you wouldn't invite to a party, both because he wouldn't show up and because if he did, he'd make everyone else miserable.

I'm looking for a moderate-to lower-pitched voice for Nathan. A solid reference would be Zuko from the animated Avatar series. He is very angsty sounding, while still having depth to his lines. He should be able to sound aggressive when necessary, and mildly irritated at most other times. The first line is meant to be sarcastic.
