Out of all Shadow’s voice actors, personally I prefer David Humphrey’s take the most. But feel free to draw inspiration from his other VA's. OR, go for something completely new and original!

Shadow is a brooding loner, to put it bluntly. He usually acts with a cool and businesslike indifference, only occasionally showing his vulnerable side. He is rarely seen with others for an extended period of time and usually distances himself from essentially everyone. He is usually soft-spoken, silent and doesn't speak much, but he always knows exactly what to say in combat. However, Shadow never bluffs. If he makes a threat, he has every intention of carrying it out.
