Optimus Prime: There are mysteries to the universe we were never meant to solve. But who we are and why we are here, are not among them. Those answers we carry inside. I am Optimus Prime, and this message is to my Creators: leave planet Earth alone, 'cause I'm coming for you!
[Bee tears off Stinger's head and feeds it to Strafe]
Bumblebee: I hate cheap knockoffs!
Cade Yeager: When you said you were done fighting for humans, you didn't mean that, did you?
Optimus Prime: How many more of my kind must be sacrificed, to atone for YOUR mistakes?
Cade Yeager: What do you think being human means? That's what we do. We make mistakes. Sometimes, out of those mistakes come the most amazing things... When I fixed you, it was for a reward. That was it. That was why. The money. And it was me making a mistake. Without it, you wouldn't be here. So even if you got no faith in us, I'm asking you to do what I do. I'm asking you to look at all the junk and see the treasure. You gotta have faith, Prime, in who we can be.
Optimus Prime: We need a new army...
[the Dinobots appear]
Cade Yeager: Sweetie, hand me my alien gun!
Joshua Joyce: How do you say "Get the fuck out of the way" in Chinese?
Optimus Prime: Honor to the end.
Optimus Prime: [to the Dinobots] Legendary warriors, the powers that created us now want us all extinguished. We must join forces, or else we'll all be their slaves. So today you stand with us... or you stand against me.
[Grimlock roars at Optimus and attacks him]
Crosshairs: We'll let Prime figure this one out...
Drift: Very wise.
Crosshairs: [climbs up a waterfall] There's no way I'm staying down with them, NO WAY!
Optimus Prime: [punches Grimlock] Only together can we survive! Let me lead you!
[Grimlock transforms into a T-rex and roars fire]
Crosshairs: Oh, no...
Drift: I was expecting a giant car!
Optimus Prime: Come here!
[Grimlock charges at Prime]
Optimus Prime: We're giving you freedom!
[sucker punches Grimlock to the ground, and draws his blade]
Optimus Prime: Defend my family, or die!
[Grimlock submits to Optimus]
Hound: I'm a fat ballerina who takes scalps and slits throats!
Harold Attinger: [holds Cade at gunpoint] You see, it takes patience to make a man. The patience to watch and wait, to protect all of us quietly, for God and country, without any recognition at all!
Optimus Prime: [as he is fighting Lockdown] Cade!
Harold Attinger: There are no good aliens or bad aliens, Yeager! It's just us and them! And you chose them...
[Optimus Prime guns down Attinger]
Cade Yeager: Anytime.
Galvatron: We will meet again, Prime... for I am reborn!
Optimus Prime: Within that man-made protype I fought, I felt the presence of Megatron.
Cade Yeager: The Decepticon who started the Chicago war?
Brains: How do you think KSI built those bots in the first place, hmm? They had a whole mess of dead Decepticon heads, and they were downloading their minds! And Iw as in charge of autopsy duty, no union, no benefits, no nothing! They hooked me up to Megatron, and that mind wasn't as dead as they thought! He fed them the science and the specs, all so he could build them a brand new body! Then he infected it with his evil nasty chromosomes! Total inside custom job! KSI might have named the body a snazzy name like Galvatron, but that's just Megatron reincarnated!
Tessa Yeager: You knew this, and you didn't warn them?
Brains: Little girl, you go into a pretty dark place when you're on death row. He's been playing KSI all this time, all so he could manipulate them into going after the Seed!
Shane Dyson: The Seed?
Tessa Yeager: Those nasty soldiers that were chasing us, I saw them take something that they called the Seed...
Hound: Sixty million years ago, give or take an eon.
Optimus Prime: Thousands of planets were cyberformed with Seeds. They turned your life into our elemental metal. Our creators destroyed your species to make us.
Brains: And that's what Galvatron wants to happen again! He wants to detonate that Seed in the biggest city and kill millions! He's going to show the world "Baby, I'm back!"
Optimus Prime: The blast wave will incinerate that city into molten metal. He'll have enough to build a massive army, and annihalate your species for ever.
Brains: You dumb greedy bastards just brought extinction to yourselves! Not my problem, though! I'm free at last! The whole thing worked out good for me!
Optimus Prime: This is not war... it's human extinction!
Hound: That's a bad idea. But then again I'm all about bad ideas.
Optimus Prime: After all we have done, humans are hunting us. But I fear we are all targets now.
[Optimus climbs on Grimlock]
Optimus Prime: Autobots, we're gonna prove who we are and why we're here!
Crosshairs: Ugh, you just want to die for the guy. That's leadership. Or brainwashing, or something.
Drift: No... that's Optimus Prime.
[the other Dinobots transform as Crosshairs rides Scorn and Drift rides Slug]
Optimus Prime: Autobots, we charge together! Now, roll out!
Harold Attinger: A new era has begun. The age of the Transformers is over...
[Optimus changes from a cab-over to a tanker]
Shane Dyson: That was insane! It was awesome, but it was insane!
Lockdown: Welcome back to the Knights Terminus, Prime.
Optimus Prime: You have disgraced it...
Lockdown: Join your fellow rebels, fugitive scum! It's for the rarest of specimens, the worst of the worst. It's taken centuries, but I've collected all the Knights, but you. The Creators want to sweep their chessboard clean.
Optimus Prime: I am slave to no one.
Lockdown: All this species mixing with species, it upsets the cosmic balance. The Creators, they don't like it. They built you to do what you were told.
Optimus Prime: Autobots, roll out!
Lockdown: [to Attinger] You promised me human intelligence... or is there such a thing?
Cade Yeager: [to Shane] You know, when I was your age, I liked to get a little wild. I liked cars, girls. But then there was Tessa. And when she was born, all I ever wanted out of life was for her to be happy and healthy and safe. Somehow I thought I'd always be enough to protect her. But I won't be. I'll never be. So somebody better be. Thanks for being here today, Lucky Charms.
Shane Dyson: Well, thanks for not shooting me when you had the chance.
Cade Yeager: I'll have more.
Shane Dyson: Yeah, I can see that.
Hound: [wedged in a building] My fat ass is stuck! Shoot 'em, Bee!
Harold Attinger: You're trying to defend your family, that's admirable. I'm trying to defend the nation from alien war.
Cade Yeager: We got a rule about messing with people from Texas.
Cade Yeager: [as he fires the alien gun] Oh, man. I'm so gonna patent this shit.
[as the Autobots reunite]
Hound: Boom time! We got the gang back together!
Hound: [to Cade] I'll cover you! If I stop covering you, that means I'm dead. But that ain't going to happen.
Galvatron: I am GALVATRON!
Joshua Joyce: Threatening a professional CIA killer. Possibly not my finest hour. I'd like to have that one back.
Darcy Tirrel: Killer? I thought they were your friends!
Joshua Joyce: No. Not friends. Business. They gave me this bomb.
Su Yueming: Bomb? Is there a bomb in the bag?
Darcy Tirrel: Yes, there's a bomb in the bag.
Su Yueming: Shit!
Optimus Prime: The hunt ends here!
Cade Yeager: [to Joshua] Hey, big shot. Your company's in serious trouble.
Joshua Joyce: You better have a damn good lawyer.
Cade Yeager: Really? Well, you better have a great one 'cause you're about to be responsible for the annihilation of a city! Now, you listen to me: your tech has been hacked, your prototypes are infected, and now Galvatron is after that Seed! Look, I know you have a conscience because you're an inventor, like me. Do not let Galvatron anywhere near that Seed!
Joshua Joyce: I control Galvatron. I created him.
Cade Yeager: Deep down, I know you know. Your prototype's been controlling you.
Hound: Human beings, buncha back-stabbin' weasels!
Drift: Hound. Find your inner compass. Loyalty is but a flower in the winds of fear and temptation.
Hound: What the hell are you sayin'?
Drift: It's a haiku.
Hound: [grabs Drift] Cut the crap before I drop a grenade down your throat!
Drift: [draws a sword] Try it, you'll be dead!
Optimus Prime: Calling all Autobots!
Crosshairs: Push, punch, press, release!
Hound: I'm a wicked warrior robot!
Cade Yeager: Will we ever see you again?
Optimus Prime: Cade Yeager, I do not know. But whenever you look to the stars, think of one of them as my soul. Defend this family, Autobots. As they have you. Defend all they can be.
Cade Yeager: Are we safer on our own, or are we safer with them?
Lockdown: Optimus Prime... come to me.
[activates a vortex]
Lockdown: Autobots, Decepticons, like little children: always fighting, making a mess out of the universe. Then I've got to clean it up.
Joshua Joyce: [sarcastically] Well, this is a great place to hide, a big glass box! Nobody will find us here.
[kicks a wall]
Harold Attinger: You got your ass kicked by a garage inventor from Texas! That goes on your resume!
Lockdown: I feel sorry for you, Prime. Your legion, these humans. The trouble with loyalty to a cause... is that the cause will always betray you!
Optimus Prime: [paralyzed] Who sent you here?
Lockdown: Where do you think you came from? You think you were born? No. You were built! And your Creators want you back!
Lockdown: We all work for someone.
Cade Yeager: I promised your mom before she passed that I'm gonna keep you safe.
Cade Yeager: You guys have never seen a truck like this before!
Lockdown: [to Cade] You see my face, your life is done!
Lockdown: He's mine now.
Crosshairs: This one's for you, a-hole!
[being shot at]
Leadfoot: I'm an Autobot! I'm an Autobot!
Joshua Joyce: [on Grimlock] He almost ate me!
Tessa Yeager: Dad! There's a missile in the family room!
[after the Dinobots come into Hong Kong]
Joshua Joyce: Good job!
Optimus Prime: YOU!
Joshua Joyce: Who?
Cade Yeager: [grabs Joyce] YOU!
Optimus Prime: Step forward! Your science will be held accountable for humanity's extinction!
Joshua Joyce: Okay, I get it with the whole socio-biological ethics thing...
Cade Yeager: There are some things that shouldn't be invented.
[Grimlock roars at Joyce]
[looks at the truck he bought]
Cade Yeager: Come on, you old wreck. Judgement Day.
Crosshairs: Let's rock!
Lucas: Thank you stranger from the corn field.
Crosshairs: [watches Drift and Bumblebee fight] I been waitin' for them all to dispatch each other so I can take charge with no trouble at all! Just me reportin' to me.
Optimus Prime: They slaughtered Ratchet... I'M GONNA TEAR THEM APART!
Lucas: They said they were gonna bring a check, I didn't know they were gonna send a death squad!
Hound: [sees Decepticons] Come and get some! You're all gonna die!
Crosshairs: Mister "Leader of the Free Galaxy" is back! I never doubted you for an instant...
James Savoy: My face is my warrant.
Optimus Prime: Charge!
Su Yueming: [to Joshua] What else are you not telling me?
Joshua Joyce: [laughs] I can't... This is really happening. A man, me, who is worth over 20 billion dollars is now being chased by CIA assassins. That's the truth. And in the middle of a robot uprising. And I'm carrying what is, in essence, a tactical nuke. And the great thing is I... The great thing is that I'm, I'm barely feeling any jetlag!
Driver of wrecked car: You better have insurance!
Cade Yeager: Insurance? It's a freaking spaceship. You go get insurance on a freaking spaceship. Good luck with that, buddy!
Joshua Joyce: [on Galvatron] Why can't we make what we want to make and make it RIGHT?
Hound: Let me vaporize his ass.
Hound: Just give me the word. I'll splatter him.
Harold Attinger: Our world will never truly be safe till all of them are gone.
Hound: Let's give it a whirl!
Lucas Flannery: We are in a lot of trouble.
Hound: Hey baldie!
Joshua Joyce: I don't wanna die like this!
Two Head: Missile!
Lucas: [last words] My foot's stuck. Cade, wait! Wait!
Optimus Prime: Bee, jump!
[Bumblebee grabs hold of Strafe]
Lockdown: [sees Tessa] Take that human to the trash!
Brains: Nobody puts baby in a box!
Crosshairs: Let's get off this Knightmare ship!
Galvatron: Detonate the Seed in the largest city!
[Joyce tries to deactivate Galvatron]
Harold Attinger: [stops him] Keep it going! Innocent people die every day!
[Galvatron starts a rampage in the KSI lab]
Harold Attinger: Joshua! JOSHUA! You have to contain it!
Joshua Joyce: [getting sucked into Lockdown's vortex] I'm going up! I'm going up!
Crosshairs: Hold your knickers, I'm punchin' it!
Brains: This is worse than Waterboy.
Cade Yeager: Where's he from?
Tessa Yeager: I told you, he's a driver from Texas.
Cade Yeager: Texas? Where, Dublin Texas? Shamrock Texas? So why does he sound like a leprechaun?
Shane Dyson: You'd get your ass kicked in Ireland for saying that.
Cade Yeager: Well, we're not in Ireland, Lucky Charms, we're in Texas!
Harold Attinger: [spots Joshua and Cade] They live, they talk, we're dead! Kill them all!
Galvatron: My brothers, I give you your freedom! From now on, you are commanded by ME! Rise up!
[all the KSI robots are now Decepticons]
Darcy Tirrel: But carbon dating puts it at 65 million years B.C.
[does B.C. make a diff when it's 65 million years?]
[a car falls out of the sky towards them]
Cade Yeager: [pointing at the car] Car!
