Fan Casting Transformers: The Last Knight

following the Hong Kong uprising, Optimus Prime arrives on a heavily damaged Cybertron, and meets Quintessa. Blaming Optimus for Cybertron's destruction, she brainwashes him, renaming him Nemesis Prime, and sends him to Earth to retrieve Merlin's staff, which can absorb Earth's energy and restore Cybertron. On Earth, Transformers remain unwelcome among humanity, and are hunted by a paramilitary force called the Transformers Reaction Force (TRF). The U.S. military, particularly Colonel William Lennox and General Morshower, are secretly against the new policy. Cade Yeager, an ally to the Autobots, hides refugee Transformers in his junkyard. In war-damaged Chicago, Cade, Bumblebee, young scavenger Izabella and her Transformer companions Sqweeks and Canopy retrieve a mechanical talisman from a dying Autobot; Cade has a standoff with the TRF and their leader, Santos, and is saved by Bumblebee, Lennox, and Hound. Megatron and the U.S. government learn of the talisman's value, and reluctantly ally.
