It looks like Optimus Prime could have some ten-wheeled competition when Transformers 4 hits theaters next year. Michael Bay's website has released an image showing the latest character to join the movie's robot alien cast, and while the previous character reveals were all Autobots, this dark and ominous Freightliner is almost certainly a Decepticon.
Based on a 2014 Freightliner Argosy cab-over semi truck, it's not exactly clear which character this is, but if the movie was to rehash old characters, this could very well be the big-screen debut of Motormaster – the leader of the Stunticons. In addition to this Freightliner, Bay's website has also posted images (but no details) for a Chevrolet Sonic Rally Car and a Pagani Huayra. There is no confirmation that either car will actually join the Autobot or Decepticon ranks, but their inclusion among all of the other confirmed Transformers would suggest they'll play some role in the movie.
