A new poster for Michael Bay's Transformers: The Last Knight has been revealed and features a seemingly corrupt Optimus Prime, under a tagline that reads "Rethink Your Heroes". After witnessing Optimus attack Bumblebee in the first trailer, it's clear Prime has lost his way and will become somewhat of a villain in the new Transformers installment. Check out the new poster and let us know what you think in the comments section!
