G1 - Frank Welker BW/Amarda/Energon/Cybertron - David Kaye Movie - Hugo Weaving Animated Series - Corey Burton Nonetheless, each VA is very suiting to their incarnation of Megatron I could never picture David Kaye voicing Megatron in the movie, the presentation would be less than menacing. But overall, what is your preferred voice. For me it's a tie between Welker and Weaving, both voices have that scratchy effect and makes him sound well fearsome and monstrous. Nothing against Kaye's but his has somewhat of a aristocratic feel to it for me. I picutre his voice being lent more towards a villian like Lex Luthor, Xanatos or something. Something that is human nonetheless. I can't really comment on Burton's as of yet.
