Autobots, roll out! It’s you and me, Megatron. I’ll take you all on! Give me your face! We will kill them all! Time to find out! “It’s you and me, Megatron.” It’s that line that works for me. It kind of symbolizes the fact that (within the continuity of the first film) the War centered on both of them, and that it would all begin and end with the two of them.
