Well that's kind of difficult. The Dark Dragon hasn't appeared much in Season 1 或者 2, having only appeared in 4 episodes ("Dragon Summit", "Hong Kong Knights", the end of "Being Human", and "Hong Kong Longs") and the Huntsman is the main antagonist of the series. I would say though that both of their voice actors, Jeff Bennett (Huntsman) and Clancy Brown (Dark Dragon), are good. But I'd say Jeff Bennett. I know it's pretty biased as I've seen 更多 stuff with him, but he is a fantastic voice actor and has been in a crapload of stuff.
