Optimus Prime: Autobots, transform and gravitize!
[the Autobots lock their feet onto the Space Bridge]
[Bulkhead loses balance upon magnetizing himself to the Space Bridge]
Bulkhead: [to himself] Don't look down... Or up... Or left.
Megatron: Optimus Prime. Never disappoints... Unlike YOU, Starscream!
Optimus Prime: Ratchet! Have Agent Fowler alert the array staff to the security hazard.
Agent Fowler: You! Soldier! You're out of uniform. Put on some pants!
Ratchet: That may be a challenge.
Ratchet: Optimus, I must say, the Space Bridge is our sole hope of ever returning to Cybertron. Are you certain its destruction is the only option?
Optimus Prime: I am afraid so.
Ratchet: Then by all means, let us light our darkest hour!
Starscream: Surely, Lord Megatron, the Autobots are up to something.
Megatron: Reeeally, Starscream?
[Starscream shows a frightened grin. Megatron deploys his army of drones]
Megatron: Crush them!
Megatron: Your fellow Autobots are wise, Optimus. They know when to retreat.
Optimus Prime: I hold no illusions about engaging your army, Megatron. But I might derail its objective... by removing its head.
Megatron: [laughs] Highly unlikely, Optimus. As I am infused with their very might!
Optimus Prime: One shall stand, one shall fall.
Megatron: Ah, misdirection, Optimus. You would have made a fine Decepticon.
Optimus Prime: I chose my side.
Starscream: Decepticons! It is with deep sorrow that I note for the log... Megatron's Spark has been extinguished. All... hail... Starscream.
[Bumblebee brings in a weak and wounded Arcee]
Jack Darby: Arcee.
Arcee: Jack... really? There are other motorcycles in the world.
Jack Darby: But you're my first.
Ratchet: Optimus, if you leave me stranded on a planet teeming with humans, I will never forgive you.
Optimus Prime: Without a means of leaving this world, we Autobots take strength in the bonds we have forged with our three young friends. True warriors, if not in body, then in spirit. My name is Optimus Prime and I send this message. Though we did not choose to be of Earth, it would seem that we are here to stay. If you approach this planet with hostile intent, know this: We will defend ourselves. We will defend humanity. We will defend our home.
