We all know Frank Welker is the original Megatron from the G1 series and he is currently doing Megatron voices either in Video Games or current Tv series and I believe he is now Hugo Weaving's replacement for the Movieverse. But what if Frank Welker decided to retire? Who could take his place for Megatron in any future TV Series or Movies? We all know there were other actors who Played Megatron in the past like David Kaye or Corey Burton. Just who could match up Welker's rasping voice? I guess I also ask if Frank Retired, who would also take his place as Freddy from Scooby Doo? Since he is also the original and currently doing TV and Movies today.
