TOM 5 was the seventh host of Toonami and the sixth incarnation of TOM after TOM 3.5. TOM 5 was voiced by veteran voice actor Steve Blum. This version of TOM remained in service for over 6 years, from April 27, 2013 to November 30, 2019, when he was killed by the Forge Commander in episode 4 of The Forge. His matrix was then uploaded into the TOM 6 body by SARA.
The backstory of how TOM 3.5 became TOM 5 has yet to be revealed and most likely will remain that way.
