During the Credits
There is an extra scene at the start of the credits of Transformers: The Last Knight.
In the extra scene, a woman is shown walking in the desert on Earth. As she makes her way towards a group of people studying a horn sticking out of ground, she warns a man not to touch it because “HE wouldn’t like it.” The man responds “Who?” and she responds, “Unicron.”
