Can you explain the Optimus plot and its resolution?
Optimus lands on cybertron. A ghost lady brainwashes him to help cybertron take over unicron (which is actually Earth). Skip to end because Optimus is not even in the movie. Cybertron collides with Earth and Optimus is kicking Earth's butt for a few seconds. He has bumblebee down and bumblebee speaks with normal voice, don't know how. Optimus says he hasn't heard that voice in forever and is unbrainwashed. Humans save Earth Optimus gives speech end movie
May not be completely accurate because I was bored out of my mind watching this
