Autobots must escape sight from a bounty hunter who has taken control of the human serendipity: Unexpectedly, Optimus Prime and his remaining gang turn to a mechanic (Mark Wahlberg), his daughter (Nicola Peltz), and her back street racing boyfriend (Jack Reynor) for help.

[last lines]
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!
Cade Yeager: Teenagers...
Optimus Prime: I went through the same thing with Bumblebee.
Joshua Joyce: How do you say "Get the fuck out of the way" in Chinese?
Cade Yeager: Sweetie, hand me my alien gun!
Joshua Joyce: The original Bumblebee was inferior in every way!
Bumblebee: You motherfucker!
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: You have no soul!
[runs Galvatron through with his sword]
Galvatron: That is why I have no fear!
[from trailer]
Optimus Prime: We need a new army...
[the Dinobots appear]
[from trailer]
[Cade jumpstarts a truck with a cable]
Optimus Prime: Calling all Autobots...
Cade Yeager: I think we just found a Transformer!
Hound: I'm a fat ballerina who takes scalps and slits throats!
[Bee tears off Stinger's head and feeds it to Strafe]
Bumblebee: I hate cheap knockoffs!
[from trailer]
Optimus Prime: This is not war... it's human extinction!
[Bumblebee knocks down Stinger]
Joshua Joyce: [looks at Shane] What did you touch?
Bumblebee: [through radio] "I told you homeboy! You can't touch this!"
[from trailer]
Optimus Prime: Who sent you here?
Lockdown: You think you were born? You were built! And they want you back.
Harold Attinger: I'm gonna ask you this once. Where is Optimus Prime?
Cade Yeager: You tell me.
[from trailer]
Harold Attinger: A new era has begun. The age of the Transformers is over...
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]
[Cade tends to Optimus Prime]
Optimus Prime: Cade, why are you willing to help me?
Cade Yeager: Cause you trust me to.
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]
Drift: We must act with stealth and silence...
[sees a tentacle]
Drift: Arrrggh! I kill you!
[from trailer]
Optimus Prime: After all we have done, humans are hunting us. But I fear we are all targets now.
James Savoy: You should never have hidden that truck!
Cade Yeager: You shouldn't have come after my family!
James Savoy: Tough luck, Yeager. We all have family!
Cade Yeager: Yeah, but at least I'm going to live to see mine.
[knocks down Savoy with a football]
Optimus Prime: Honor to the end.
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...
[from trailer]
Cade Yeager: We got a rule about messing with people from Texas.
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.
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 now too! We have to find out why we'll never get our lives back again!
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 changes from a cab-over to a tanker]
Shane Dyson: That was insane! It was awesome, but it was insane!
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?
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!
Hound: That's a bad idea. But then again I'm all about bad ideas.
[from trailer]
Optimus Prime: Autobots, roll out!
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!
Hound: [wedged in a building] My fat ass is stuck! Shoot 'em, Bee!
[from trailer]
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: [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.
Cade Yeager: [as he fires the alien gun] Oh, man. I'm so gonna patent this shit.
Galvatron: I am GALVATRON!
Bumblebee: You gotta listen...
Tessa Yeager: No, YOU listen! I'm not leaving my dad!
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!
Shane Dyson: Hang on, baby.
Cade Yeager: Who is this? Who are you? And who are you calling baby?
[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!
Lockdown: [to Attinger] You promised me human intelligence... or is there such a thing?
Cade Yeager: What'd you buy deodorant for?
Shane Dyson: I like to smell fresh when I'm making out with your daughter.
Optimus Prime, Cade Yeager: There remains a price on my head. I endanger you all if I stay. I shall take the Seed where it can never be found.
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.
[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.
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.
[from trailer]
Optimus Prime: Charge!
Cade Yeager: Are we safer on our own, or are we safer with them?
Optimus Prime: Brave warriors, you are free!
[the Dinobots roar and leave]
Crosshairs: I'll ride with you anytime, Spike!
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.
Joshua Joyce: Did you miss me?
Su Yueming: [blushes] No.
Hound: I'm a wicked warrior robot!
Cade Yeager: This is a non-dating house. You don't date, I don't date!
Tessa Yeager: Maybe you should.
[from trailer]
Harold Attinger: You're trying to defend your family, that's admirable. I'm trying to defend the nation from alien war.
[from trailer]
Cade Yeager: You guys have never seen a truck like this before!
[as the Autobots reunite]
Hound: Boom time! We got the gang back together!
Cade Yeager: I promised your mom before she passed that I'm gonna keep you safe.
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: [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.
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: [to Cade] I'll cover you! If I stop covering you, that means I'm dead. But that ain't going to happen.
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]
[from trailer]
Optimus Prime: The hunt ends here!
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...
[from trailer]
Harold Attinger: Our world will never truly be safe till all of them are gone.
[repeated line]
Optimus Prime: Calling all Autobots!
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."
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: 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.
Optimus Prime: [draws a Cybertronian sword] Recognize one of your knights!
[releases the Dinobots from their cell]
Optimus Prime: [in Cybertronian] The legend exists.
[looks at the truck he bought]
Cade Yeager: Come on, you old wreck. Judgement Day.
James Savoy: My face is my warrant.
Joshua Joyce: [on Galvatron] Why can't we make what we want to make and make it RIGHT?
Hound: Optimus, what are our orders on these humans? Can I squish the bald guy?
Optimus Prime: They're in trouble...
Crosshairs: Nah! This isn't our fight! I'm done being an underdog, underdogs suck! I say they get what they deserve!
[from trailer]
Su Yueming: [to Joshua] What else are you not telling me?
Cade Yeager: How fast can this thing go?
Drift: Very fast. It's a spaceship.
Crosshairs: Let's rock!
Crosshairs: Push, punch, press, release!
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!
Lucas Flannery: We are in a lot of trouble.
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: Yeah, we call it a soul.
Lockdown: Optimus Prime... come to me.
[activates a vortex]
Lucas: Thank you stranger from the corn field.
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!
Lockdown: [sees Tessa] Take that human to the trash!
James Savoy: [spots Joshua and Cade] They live! They talk, we're dead!
Harold Attinger: Kill them all!
Lockdown: Autobots, Decepticons, like little children: always fighting, making a mess out of the universe. Then I've got to clean it up.
Lockdown: He's mine now.
Hound: [sees Decepticons] Come and get some! You're all gonna die!
[opens fire]
[from trailer]
Hound: Let's give it a whirl!
[being shot at]
Leadfoot: I'm an Autobot! I'm an Autobot!
Tessa Yeager: Dad! There's a missile in the family room!
Crosshairs: This one's for you, a-hole!
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: We had a deal! You got what you wanted!
Joshua Joyce: [taking the Seed] I got what IT wanted!
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.
Harold Attinger: You got your ass kicked by a garage inventor from Texas! That goes on your resume!
Lucas: They said they were gonna bring a check, I didn't know they were gonna send a death squad!
Lucas Flannery: What is that? Look's like a missile.
Cade Yeager: It is. Watch out!
[missile goes off]
Cade Yeager: Hey, you!
[engages Lockdown]
Optimus Prime: Cade, get back! This is my fight!
Lockdown: It's MY fight now, and you're all gonna die!
Crosshairs: Mister "Leader of the Free Galaxy" is back! I never doubted you for an instant...
[first lines]
Arctic Site Foreman: Oh, shit. Darcy, you really shouldn't have come.
Darcy Tirrel: Show me.
Optimus Prime: They slaughtered Ratchet... I'M GONNA TEAR THEM APART!
Brains: This is worse than Waterboy.
[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]
Landlord's Grandson: He's deaf and senile.
Theater Landlord: I heard that.
Brains: Nobody puts baby in a box!
Joshua Joyce: [on Grimlock] He almost ate me!
Joshua Joyce: I don't wanna die like this!
Hound: Just give me the word. I'll splatter him.
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.
Lucas: [last words] My foot's stuck. Cade, wait! Wait!
Two Head: Missile!
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 Yeager: What do you want me to do?
Joshua Joyce: THROW IT!
Hound: Give, give, give!
[Cade hurls it at Hound who tosses it at some Decepticons]
Lockdown: There is one way you survive: tell me where he's hiding. Where is Optimus Prime?
Ratchet: Never.
[Lockdown kills Ratchet]
Lockdown: Never is here.
Joshua Joyce: [getting sucked into Lockdown's vortex] I'm going up! I'm going up!
Cade Yeager: Kind of nice being your hero for a change.
Tessa Yeager: You always were, all my life.
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!
Optimus Prime: Bee, jump!
[Bumblebee grabs hold of Strafe]
Hound: Hey baldie!
Gill Wembley: [gets a message from Joshua] "Need to know the Seed's estimated blast range." Duh!
Gill Wembley: [message] Like a tactical nuke, LOL!
Crosshairs: Hold your knickers, I'm punchin' it!
[about to break into Lockdown's ship]
Cade Yeager: Look, you wanna cut and run, you better do it now. I'm gonna die trying.
Shane Dyson: Hey, I'm not here to help you get your daughter, you're here to help me get my girlfriend.
Hound: [unsehathes a knife] Got your fortune cookie!
[guts some Decepticons]
Hound: Come here, you little punk!
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.
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]
Crosshairs: Let's get off this Knightmare ship!
Lockdown: Where is my escaped bounty?
Harold Attinger: Autobots at this location... Prime is close... Do whatever you have to do.
Lockdown: I intend to.
Hound: Let me vaporize his ass.
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?]
Lockdown: I feel sorry for you, Prime. Your legion, these humans. The trouble be 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!
[Smirks]
Lockdown: We all work for someone.
Galvatron: Detonate the Seed in the largest city!
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!
Gill Wembley: Galvatron was...
Joshua Joyce: A fiasco. An embarrassment. And he spoke, how did that happen? You know what a flaw is, Wembley? A flaw is a total failure. I do not have control over my prototype, and I want to know why!
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
