Reno Wilson
From Teletraan I: The Transformers Wiki
Reno Wilson is an American character actor, comedian and voice actor. Some of his better known roles are as Sonny on "Martin", Howard on "The Cosby Show", and Thirst in the Sprite commercials.
His voice for Frenzy in the live-action movie was apparently done real-time, without special editing to speed it up or modulate it.
