Optimus Prime: [Morse code] I'm coming for you, humans...

Sir Edmund Burton: It has been said throughout the ages, that there can be no victory, without sacrifice.

Bumblebee: [Optimus stabs at Bumblebee, barely missing his head] "I-I am Bumblebee, your oldest friend. Optimus. I would lay down my life for you."

Quintessa: There is a way to heal your world. My power of creation, the staff, was stolen from me by my twelve Guardian Knights. They betrayed me, and hid it on Earth... gave it to your precious humans. The staff is the only way to bring life back to Cybertron. You are going to find it for me. Do you seek redemption, Prime? Do you?
Optimus Prime: My maker,
I do.

Optimus Prime: Knights, Autobots. This cannot and will not be the end. To save earth and her people we are going to steal Quintessa's staff. Only you, Vivian, can take it back. I will lead the way into her chamber. And when the account of the ages is etched into the cosmos, let those who exist long after us know that this was our finest hour!
[blasts into the sky]
Crosshairs: Love that guy. Goosebumps every time.
Hound: I never got to say hi.

Optimus Prime: [attacks Infernocus] You ugly menace!
[slices apart the combiner]
Optimus Prime: Did you forget who I am?
[decapitates all the Infernocons]

Sir Edmund Burton: [after Bulldog fires a warning shot at Cade and co] We have guests! What's wrong with you?
Bulldog: I got bits falling off!
Bumblebee: [Through radio] What the hell?
Sir Edmund Burton: I'm awfully sorry about that but, you see, he still thinks it's 1918 or 1915, 'Robot Dementia'. It's not
all pretty.
Cade Yeager: Are you dragging me into some transformer retirement home?
Cogman: Mm-hmm!
Cade Yeager: Somebody better start talking or I'm outta here!
Sir Edmund Burton: Yes, but you want to know, don't you? why they keep coming here. to earth, right?
[Hot Rod is seen speeding down the
lane]
Sir Edmund Burton: Ah, I do so love perfect timing!
[Hot Rod transforms and throws out Vivian, she tries to attack him]
Hot Rod: Little lady, no!
[Gets hit by the club, the golf head coming off on impact]
Hot Rod: Ow!
Cade Yeager: So, is this a kidnapping sort of situation or her
first Transformer experience?
Sir Edmund Burton: Well, it's both really.
Hot Rod: She's very difficult!

[last lines]
Optimus Prime: At the heart of every legend, there is truth: a few brave souls unite to save the world. We can be heroes in our own lives, every one of us, if we only have the courage to try. Our fates were always intertwined, but now our worlds are joined as one. We need to repair our planets, work together, if we wish to survive. A dangerous secret is buried
deep inside the Earth. There is more to this planet than meets the eye. I am Optimus Prime, calling all Autobots: It is time to come home.
