[The Autobots meet Sam and Mikaela in an alley]
Are you Samuel James Witwicky, descendant of Archibald Witwicky?
Yeah.
My name is Optimus Prime. We are Autonomous Robotic Organisms from the planet Cybetron.
But you can call us "Autobots" for short.
Autobots.
What's crackin', little bitches? [does a somersault]
My first lieutenant. Designation: Jazz.
This looks like a cool place to kick it! [jumps onto a car behind him as if it were a chair]
What is that? How did he learn to talk like that?
We've learned Earth's languages through the World Wide Web. [points to Ironhide] My weapons specialist, Ironhide.
Easy, Ironhide.
Just kidding, I just wanted to show him my cannons.
Our medical officer, Ratchet.
[Mikaela scratches her head in embarassment - Sam whistles]
You already know your guardian, Bumblebee.
Bumblebee, right? You're my guardian, huh? [Bumblebee nods]
His vocal processors were damaged in battle. I'm still working on them.
Why are you here?
We are here looking for the All Spark, and we must find it before Megatron.
Mega-what?
[produces a hologram of Cybertron for Sam and Mikaela to see]
Our planet was once a powerful empire, peaceful and just, until we were betrayed by Megatron, leader of the Decepticons. All who defied them were destroyed. Our war finally consumed the planet, and the Allspark was lost to the stars. Megatron followed it to Earth, where Captain Witwicky found him.
My grandfather...?
It was an accident that intertwined our fates. [flashbacks to Archibald's discovery of Megatron in the ice] Megatron crash-landed before he could retreive the Cube. He accidentally activated his navigation system. The coordinates to the Cube's location on Earth were inprinted on his glasses.
How did you know about his glasses?
eBay.
eBay...
If the Decepticons find the Allspark, they'll use its power to transform Earth's machines, and build a new army.
And the human race will be extinguished. Sam Witwicky, you hold the key to Earth's survival.
