Speak Well, He Can
An interview with the voice of Yoda
Tom Kane can do a good evil robot. He gets a lot of computer voices thrown his way. Stanley Kubrick even picked him to be the new HAL 9000 from 2001: A Space Odyssey just before Kubrick died. Kane's also done a ton of animation voicings, including Professor Utonium in “The Powerpuff Girls” and Monkey Fist on “Kim Possible.” He was both Tony Stark and Ultron in the "Iron Man" cartoons, so he got to fight himself.
