6. Thane Krios
The assassin with a heart of gold is hardly a new concept. If I see one more student film where a hitman has a crisis of conscience, I'm probably going to lose my mind. But there was something very distinct about Thane. Maybe it was his voice, which was some truly unique voice acting. Maybe it was his photographic memory, which he occasionally narrated out loud for the benefit of anyone unfortunate enough to not be Thane Krios. Whatever the reason, Thane is a compelling character whose tale of redemption leading up to the Battle of the Citadel is one for the ages. And damn you, Bioware, for making me cry.
