Being of East London heritage, having a naturally deep(ish) voice and well versed in the art of shouting (thanks kids), your prototypical ork is on my vocal menu.

I always get asked for a Gandalf impression (which, in practice, is quite some way off Ian Mckellen, but definitely wizard like), but I can give you that Lord Of The Rings darkside too. 

The video over there is a gameplay run through for a dungeon crawler called Orc: Vengeance, in which I voiced the main character Rok, and a list of the bad guys he came across; including savage end of game gentleman called The Dark One (also featured in the video).

So if you like your villains to sound green and like they need a throat lozenge, I can help!
