After the battle took place in Hong Kong, Optimus Prime was already hoping that it was over. But no. He is waiting for a new threat. The case took a serious turn, and Optimus understands that without support he can not cope. The enemy is too powerful to even Optimus Prime deal with it alone.
Transformers and people again at the same time!
Therefore, he needs to find allies. And Optimus leaves our planet to find them in the galaxy. But the Earth does not remain without protection, because there are Bumblebee, Drift, Hound, Trailbreker, Crosshase, Blair and dinobots. Their goal is to stop Galvatron at any cost and not allow him to build a space bridge. After all, then the Earth is just awful prospects!
People also come to the aid of the Autobots, because they understand that now their lives are in the hands of robots. Therefore, people throw all their forces at the creation of new transformers, so that they later helped the Autobots.
