Carter Montana is the dangerous leader of an evil organization called "Team Relic". They roam the region and steal ancient artifacts that they can sell later on the black market, and they're always prepared to do whatever it takes to get rich. Carter himself is very upbeat, arrogant, and just a little bit dense. He's comparable to somebody like a 'Gaston' (from Disney's Beauty and the Beast), where because he's a little bit stronger than people he thinks he can push them around and do/steal whatever he wants.

For Carters voice I need something that, as I mentioned before, has a smug, overpowering arrogance to it. "Gaston" is pretty close to what I'm imagining (Reference: https://www.youtube.com/watch?v=O5kWyKUe2Io ), but really any kind of overbearing, obnoxious, commanding voice will do. Carter is also inspired by 1930's Adventure Serials (which is what things like Indiana Jones was inspired by), so perhaps some inspiration taken from either Indiana Jones himself or even popular 1930s radio announcers, could work well for him.
