The main beneficiary of all of these Transformers movies seems to the pop culture-loving Autobot, Bumblebee. Optimus Prime's little sidekick has gotten an upgrade with each film, and so it's no surprise that he's been revamped once more for Transformers: The Last Knight.
Michael Bay revealed on his official site that Bumblebee is returning, of course, and that he's going to be a little bit different. He's still the yellow Chevy Camaro we all know, but he's a revamped custom built version.
With Bumblebee getting his own spinoff movie in 2018 as part of Paramount's Transformers cinematic universe, don't be surprised if he gets another redesign. Or perhaps not; the constant upgrades could be a Bay thing, and he's finished with the franchise after Transformers: The Last Knight opens on June 23rd 2017.
