Klein is a curious, naive, hopeful little orphan. He has a goal to get adopted with his best friend Riley, but their bond gets in the way of either of them leaving the orphanage. Klein is just that committed to Riley. 

For his voice actor, older age voice actors are heavily preferred. I want to steer away from children taking the room only due to the fact children's voices change. Any gender works for this part, although we would prefer a voice actress.

In terms of vocal direction, we are allowing our voice actors to experiment with whatever voice they see fit the design. We want to steer away from a raspy voice. (Like Timmy Turner and Ash Ketchum for example) A voice inspired by Bart Simpson is what we are aiming for.
