Mauricio Berger is a Brazilian voice actor.
Berger is one of the most recognized voice actors in Brazil thanks to his extremely masculine voice. Because of it, he usually plays "tough guy" characters.
Among his most notable roles are: John Stewart on both Justice League and Justice League Unlimited, Goliath on Gargoyles, Batman/Bruce Wayne on The New Adventures of Batman and Robin, Sabertooth on X-Men: Evolution, Mr. Freeze on The Batman, Father on Kids Next Door and Harold on The Grim Adventures of Billy and Mandy.
He was also the voice of the titular character of the TV series Angel, and he made David Boreanaz sound a lot tougher than he really is.
Seriously, he sounds like he's 11 feet tall!
