He is really confident in his ability. He cherishes his little brother a lot to where he rushes in alone into a school full of zombies to save him. I'd imagine him having a medium-ranged voice with a lot of confidence behind it. He only appears once (Episode 16) and then doesn't appear again until the last 10 Episodes of the 1st Season. So whoever gets cast as him, will get other roles to voice as we go on with this project.
