Dee Bradley Baker (voice of Momo and Appa) recently revealed that he will be playing more than one part in Avatar: The Legend of Korra. We had known that he would be voicing a character for the upcoming mini-series, but now we know a bit more about just what Baker will be voicing. According to a reply Baker made on his Twitter account, the seasoned voice-actor will be voicing an actual person in addition to Korra’s animal.
Fan speculation has been that Korra will have an animal transport friend similar to Roku's dragon, Fang, or Aang's sky bison, Appa. Just what type of animal Korra will have is anybody's guess, as is what human character Baker will be voicing. But that can't keep us from speculating.
