Ike, Boyd, or Oscar from Fire Emblem: Path of Radiance. I love that game to death and I have always had a really specific idea of how they sound, so I've always wanted an opportunity to bring their characters to life vocally.
I've also always wanted to play Cyrano in Cyrano de Bergerac, my favorite play, or Eric in Phantom of the Opera.
The good news is that I was just cast in a Path of Radiance fandub and I even now am in the production process for my very own audio play rendition of Cyrano de Bergerac.
Dreams come true!
