Mario is (obviously) the main character of the game and the hero of the Mushroom Kingdom. He's a bit of a blank slate silent protagonist throughout the majority of the game, although he has a few dialogue options where he can be a bit more expressive.

You know how Mario sounds. I'm looking for the classic, Charles Martinet voice for Mario. (Although I am definitely not against giving a chance to a more Italian-American sounding voice, like in the TV show or in the Illumination Mario Movie)

This role will only have a few lines here and there in each chapter, as Mario only really has dialogue in the few moments in the game where you pick a dialogue option.
