Orson is a diamond dog of the Manehattan Mafia, who serves as one of Al Gazillion's top field enforcers.  He's Gazillion's de facto muscle and acts as his personal spokesman when the don himself is unable to attend a meeting.  A towering brute, Orson relies on overwhelming strength and power to steamroll the opposition.  He's not all brawn; he's fairly intelligent and carries out Al's orders to the best of his ability, be it through Al's meticulous planning or his own cunning and knack for improvisation.  Orson is all business and no-nonsense.  He's very straightforward and blunt with his intentions, wasting no time making wisecracks or witty repartee.  

I'm not picky if he has an accent or not.  But I do want Orson's voice to sound deep, menacing, and serious, as well as blunt.  Try to give a guttural growl to his voice as well.
