For a couple of plot details, click "read more."
- Lockdown has a ship full of decommissioned Transformers, with the Dinobots among them.
- Optimus Prime is captured and is able to recover the Dinobots and somehow bring them back to life (I'm assuming they're in some type of stasis).
- Optimus, Bumblebee and possibly others will ride the Dinobots into battle in Hong Kong.
- Optimus will be on Grimlock, while Bumblebee rides Swoop.
