Sasuke Uchiha
When he auditioned for "Naruto", which was being directed by the same person who did "Rave Master", he had tried out for multiple roles including Sasuke Uchiha and Iruka, and got a call back for Sasuke. In an interview with Silionera, Lowenthal said that "It certainly allows me to go to some dark places as the series continues. And it makes Sasuke that much more interesting as a character. And that much more fun to play." The "Naruto" anime became one of the more popular anime shows in the U.S., and its sequel "Naruto Shippuden" has also aired on Adult Swim.
