Sean, Mikaela, and Bumblebee arrive in a back alley, and the three humans get out of the car. Bumblebee changes back to his Autobot form as four vehicles drive towards you.
Optimus Prime: The leader of the Autobots.
Bumblebee: The Autobot scout and Sean's new guardian.
Jazz: Optimus's second-in-command.
Ratchet: The Autobot medic.
Ironhide: The Autobot weapons expert.
Optimus transforms into his Autobot form and kneels in front of Sean and Mikaela. He then says in an authoritative tone, “Are you Sean James Witwicky, a descendant of Archibald Witwicky?”
Mikaela's eyes widen, and she leans closer to Sean and whispers to him, “How—he knows your name?”
Sean's eyes flick to Mikaela as he hesitantly gives a small nod. He nervously looks at Optimus and then says, “Y-yeah.”
