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!
Joshua Joyce: How do you say "Get the fuck out of the way" in Chinese?
Optimus Prime: We need a new army...
[the Dinobots appear]
Cade Yeager: You're not actually leaving, are 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.
Drift: [after seeing Grimlock transform into his dinosaur mode] I was expecting a giant car.
[Bee tears off Stinger's head and feeds it to Strafe]
Bumblebee: I hate cheap knockoffs!
Optimus Prime: You have no soul!
[runs Galvatron through with his sword]
Galvatron: That is why I have no fear!
Optimus Prime: Who sent you here?
Lockdown: You think you were born? You were built! And they want you back.
[Bumblebee knocks down Stinger]
Joshua Joyce: [looks at Shane] What did you touch?
Bumblebee: [through radio] I told you homeboy! U can't touch this!
[Cade tends to Optimus Prime]
Optimus Prime: Cade, why are you willing to help me?
Cade Yeager: Cause you trust me to.
Optimus Prime: This is not war... it's human extinction!
Hound: I'm a fat ballerina who takes scalps and slits throats!
[Cade jumpstarts a truck with a cable]
Optimus Prime: Calling all Autobots...
Cade Yeager: I think we just found a Transformer!
Optimus Prime: A great threat is coming...
Cade Yeager: What if you had some human help?
Tessa Yeager: You're his partner now?
Cade Yeager: Sweetie, we're targets too!
Hound: [fires shots into the air] Oh yeah! HELL YEAH! He's back! He's alive! OPTIMUS IS HERE!
Drift: At last, there is hope after all...
Crosshairs: Ugh, you just want to die for the guy. That's leadership. Or brainwashing, or something.
Drift: No, that is Optimus Prime.
Galvatron: We will meet again, Prime... for I am reborn!
Harold Attinger: [holding Cade at gunpoint] There are no good aliens or bad aliens! It's just us, or them... and you chose them over us!
[Optimus guns down Attinger]
Cade Yeager: Any time.
Joshua Joyce: [to Cade] I may have started the apocalypse, but you brought your family. And that's, you know, terrible parenting.
Cade Yeager: I'm about one second away from knocking you out, taking the bomb and just leaving you here.
Joshua Joyce: Do me the favour, please?
Optimus Prime: While I was fighting the machine, I felt the presence of my old nemesis.
Cade Yeager: Megatron?
Brains: How do you think they made those drones? KSI captured all those robot remains from Chicago and started tearing them up! They made me a morgue assistant. It turned out, Megatron wasn't as dead as they thought! It's a different name, but the same bot underneath!
Optimus Prime: After all we have done, humans are hunting us. But I fear we are all targets now.
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.
[the Dinobots roar at Optimus and attack 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]
Harold Attinger: A new era has begun. The age of the Transformers is over...
Hound: That's a bad idea. But then again I'm all about bad ideas.
James Savoy: You should have given me that truck!
Cade Yeager: You shouldn't have come after my family!
James Savoy: My family died!
Cade Yeager: Yeah, but at least I'm going to see my family again!
[shoves Savoy out a window]
Joshua Joyce: I can't believe I'm putting my life in your hands.
Cade Yeager: You want the alien gun? Take it!
Joshua Joyce: No, I don't want the alien gun.
[looks at an adorable alien in a cage]
Hound: You don't look so dangerous...
[the alien spits acid at him]
Hound: ARRGGHHH! I'm hit! Alright, I gotta hurt you now, you're just too disturbing to live...
[shoots the alien]
[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.
Lockdown: [to Attinger] You promised me human intelligence... or is there such a thing?
[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!
Drift: Bumblebee has held the command while you were gone, he is a child who lacks leadership.
Bumblebee: Well this child is about to kick your ass.
Cade Yeager: We got a rule about messing with people from Texas.
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.
Optimus Prime: [sees Leadfoot and Ratchet get killed by humans] I have sworn to never kill humans...
Hound: Big mistake.
Optimus Prime: ...but when I find out who's behind this, he's going to die.
Cade Yeager: [to Shane] Thanks for looking after my daughter, Lucky Charms.
Cade Yeager: We're going to save Prime!
Crosshairs: Why should we? What's in it for me?
Hound: [puts a gun to Crosshairs's head] What's in it for you is I don't kill ya. We're gettin' the boss back, and the girl!
[Su takes out a couple of goons]
Joshua Joyce: How'd you do that?
Su Yueming: Police academy, before my MBA.
Joshua Joyce: I love you.
Darcy Tirrel: That's a bomb?
Su Yueming: They gave you a bomb?
Joshua Joyce: [upset] Yeah...
Cade Yeager: [as he fires the alien gun] Oh, man. I'm so gonna patent this shit.
Hound: [to Cade] I'll cover you! If I stop covering you, that means I'm dead. But that ain't going to happen.
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.
Tessa Yeager: Dad, you can't keep spending money on junk...
Cade Yeager: I can break it down, strip it for parts. This stuff is what's going to put you in college!
Cade Yeager: This is a non-dating house. You don't date, I don't date!
Tessa Yeager: Maybe you should.
Optimus Prime: The world will know what you did here!
Joshua Joyce: The world? The world will approve! We can make you now. Don't you get it? We don't need you anymore.
Harold Attinger: Here on Earth we have a saying: "The enemy of my enemy is my friend."
Lockdown: I also have a saying: "I don't care."
Cade Yeager: Are we safer on our own, or are we safer with them?
Optimus Prime: Dinobots, you are free!
[the Dinobots roar and leave]
Crosshairs: I'll ride with you anytime, Spike!
Cade Yeager: [to Joshua] You're an inventor like me, so I know you have a conscience. Don't let your creation take control.
Joshua Joyce: I created Galvatron, I control him!
Cade Yeager: No, he's been controlling you!
Crosshairs: [examines the workings of Lockdown's ship] We got a little jujube here... Hello, mama!
[removes a component, and the ship sets off its anchors]
Lockdown: Who fired the anchors? Who's on my ship?
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!
Cade Yeager: You guys have never seen a truck like this before!
Joshua Joyce: What we do here is science. Because if we don't do it, somebody else will. Because you cannot stop technology.
Optimus Prime: We are NOT your technology!
Lockdown: [to Cade] You see my face, your life is done!
Cade Yeager: Where are you going?
Crosshairs: To lay some hate!
[opens up a paraglider and guns down ships in the air]
Cade Yeager: I promised your mom before she passed that I'm gonna keep you safe.
Cade Yeager: [examines Prime] The missile just missed your power source.
Optimus Prime: We call it a spark. It contains our life essence, and all our memories.
Cade Yeager: We call it a soul.
[looks at the truck he bought]
Cade Yeager: Come on, you old wreck. Judgement Day.
Cade Yeager: Don't look back.
Tessa Yeager: Don't say that to me now I wanna turn around!
Cade Yeager: It's nothing major, sweetie.
Tessa Yeager: That means it's totally major!
Cade Yeager: I have to point this gun in your direction, it gonna be like it's in your direction, but it's not.
Cade Yeager: What'd you buy deodorant for?
Shane Dyson: I like to smell fresh when I'm making out with your daughter.
Harold Attinger: You haven't said what you want him for.
Lockdown: Every galaxy I have traveled, all you species are the same. You all think you're the center of the universe. You have no idea...
Tessa Yeager: We can't go home, Dad. They blew it up.
Joshua Joyce: I believe I can help you with that.
[Cade embraces him in a hug]
Lockdown: Autobots, Decepticons, like little children: always fighting, making a mess out of the universe. Then I've got to clean it up.
Hound: [sees Decepticons] Come and get some! You're all gonna die!
Joshua Joyce: We got a real dilemma here, okay. I created incredible robots, it's all designed to kick that fat Transformer's ass! So, really, this is a no-win situation. It's over.
Hound: [flicks his cigar at Joyce] That was mean.
Joshua Joyce: HEY!
[being shot at]
Leadfoot: I'm an Autobot! I'm an Autobot!
Joshua Joyce: [on Galvatron] Why cant we make what we want to make and make it RIGHT?
Su Yueming: [to Joshua] What else are you not telling me?
Hound: Optimus, what are our orders on these humans? Can I squish the bald guy?
Optimus Prime: [draws a Cybertronian sword] Recognize one of your knights!
[releases the Dinobots from their cell]
Optimus Prime: [in Japanese] The legend exists.
Lucas: They said they were going to bring a reward, I didn't think they'd bring a death squad!
Joshua Joyce: [sarcastically] Well, this is a great place to hide, a big glass box! Nobody will find us here.
[kicks a wall]
Lucas Flannery: What is that? Look's like a missile.
Cade Yeager: It is. Watch out!
[missile goes off]
Tessa Yeager: Dad! There's a missile in the family room!
Optimus Prime: They slaughtered Ratchet... I'M GONNA TEAR THEM APART!
[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]
Harold Attinger: Our world will never truly be safe till all of them are gone.
Crosshairs: Mister "Leader of the Free Galaxy" is back! I never doubted you for an instant...
Hound: [throws a grenade at Cade] Pull the pin, I'm dyin' out here!
[Cade pulls the grenade]
Joshua Joyce: IT's LIVE! IT's LIVE!
[Cade hurls it at Hound who tosses it at some Decepticons]
Lockdown: Hey, you!
Optimus Prime: Cade, get back! This is my fight!
Lockdown: It's MY fight now, and you're all gonna die!
Two Head: Missile!
Harold Attinger: You got your asses kicked by a rally car driver!
Joshua Joyce: We got a real dilemma here. Ok? I created incredible robots. It's all designed to kick that fat Transformers ass. So, really, this is a no-win situation. It's over.
Hound: [flicks large artillery shell from his beard at Joshua's back] That was mean.
Joshua Joyce: Hey! I'm sorry if you can't handle the cold-hearted truth!
Hound: Optimus, what are our orders with these humans? Can I squish the bald guy?
Harold Attinger: We had a deal! You got what you wanted!
Joshua Joyce: [taking the Seed] I got what IT wanted!
James Savoy: [spots Joshua and Cade] They live! They talk, we're dead!
Harold Attinger: Kill them all!
Arctic Site Foreman: Oh, shit. Darcy, you really shouldn't have come.
Darcy Tirrel: Show me.
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.
Hound: [unsehathes a knife] Got your fortune cookie!
[guts some Decepticons]
Joshua Joyce: What was that sound?
KSI Executive: That's "the" sound.
KSI Spokesmodel: That you asked for.
Joshua Joyce: No, I asked for boundless. Transcendent. When you walk through a door in this building, it should like you stepped into the future.
Joshua Joyce: [getting sucked into Lockdown's vortex] I'm going up! I'm going up!
Lockdown: There is one way you survive: tell me where he's hiding. Where is Optimus Prime?
[Lockdown kills Ratchet]
Lockdown: Never is here.
Galvatron: My Decepticon brothers, I give you freedom! Rise up, and be commanded by ME!
Lucas Flannery: Cade, relax. You're going to have an aortic infarction.
Cade Yeager: What is that?
Lucas Flannery: I think it's a brain heart attack.
Cade Yeager: Yeah, I had one already.
Lockdown: Give me Prime, or I'll level the whole city!
Harold Attinger: [now facing inevitable ruin] Do what you have to!
