Kratos. doesn't get more epic than that.
You beat me to it. Though, it wouldn't really fit my appearance.
Has Alan Rickman voiced Snape in any Harry Potter games? I'd pick his voice and accent.
I like doing impressions of characters, but I probably fail miserably.
Oh yes. Snape would be a good one. Also Jeremy Irons as Scar from The Lion King. Very regal.
