Two opposing factions of transforming alien robots engage in a battle that has the fate of Earth in the balance.

Ultra Magnus: I've never seen anything this beautiful in the entire galaxy - alright, give me the bomb.
Trailbreaker: [after escaping attack] Thanks for your help, brothers!
Sunstreaker: What about my paint?
Sideswipe: Don't worry. No one will notice. Just make left turns!
Megatron: [charging into battle] SHOW NO MERCY!
Starscream: [sarcastically] Did we ever?
Quintesson: You are the Autobot called Kup. You are Cybertron's chief of security.
Kup: Nah, my name's Teaspoon, and I'm Cybertron's chief dishwasher.
Hot Rod: This is ridiculous. Doesn't he know who we are?
Kup: Maybe we should get a new P.R. man.
[repeated line]
Optimus Prime: Autobots, transform and roll out!
Wreck-Gar: Kemosabes Rodimus and Ultra Magnus, you are in danger of being cancelled or losing your time slot.
Ultra Magnus: What did he say?
Rodimus Prime: We're gonna get killed.
Optimus Prime: Sometimes even the wisest of man or machine can make an error.
Snake: It's hard to find good help these days... COBRA!
Jazz: Maybe Ironhide's ready for a nice, cushy office job.
Starscream: Time makes all things possible. I can wait.
Skuxxoid: They paid good money, okay?
Arcee: The Decepticons?
Skuxxoid: The who? Oh - I mean yes, of course! The Decepticons...
Jazz: We'll be right back! Just don't move.
Omega Supreme: Sarcasm not appreciated.
Megatron: Your knowledge is only overshadowed by your stupidity!
Slag: Which one friend?
Sludge: [points at Autobot insignia on chest] Ones with face like this, uh, I think.
Slag: That good enough for Slag!
[fires at Decepticons]
Megatron: Can't Thrust carry out a simple mission?
Starscream: I think the answer is obvious.
Blitzwing: If I want to know what's on your mind, I'll splatter it on the wall and see for myself!
Starscream: [looking at the Dinobots] You're supposed to know everything. What are those?
Megatron: Scrap metal, once we finish with them!
[Fires his cannon at the Dinobots]
Megatron: Ah, my loyal Constructicons. You are loyal, aren't you? No! You're traitors! And you can't deny it!
Scrapper: Megatron, y-y-you've got it all wrong!
Hook: We're still working for you and for the glory of the Decepticons.
Bonecrusher: You see, we eavesdropped on their plans...
Long Haul: ...plans to build a whopper solar tower...
Scavenger: ...that would produce mega-watts of energy!
Mixmaster: Energy we could use to destroy the Autobots! Get it, get it, huh?
Rumble: If on Decepticon turf you happen to tumble, look out now, 'cuz here comes Rumble!
Scourge: [Cyclonus, Scourge and the Sweeps are standing at the entrance shaft to the Decepticon Crypt] . You go down that shaft!
Sweep #1: How come I've got to do the dirty work?
Scourge: You see if the traitor is hiding down there!
Sweep #2: No way! If you're so fired up to know what's going on you go down there!
Scourge: You lead!
Sweep #3: I don't want anyone thinking that I question you as a leader, but sorry!
Cyclonus: I question your leadership skill Scourge. The last one in there will face me!
Cyclonus: [All three Sweeps quickly dive down the shaft] . You have much to learn.
Scourge: Yes it is true.
Cyclonus: Now dive!
[Cyclounus and Scourge dive down the shaft]
Cyclonus: .
Starscream: I will rule the universe, even if I am the only one left in the universe.
Quintesson No. 1: It is a day so long in coming that I am uncertain how to celebrate it.
Quintesson No. 2: Perhaps... a quiet chuckle.
Quintesson No. 1: Very well, then. Let us... chuckle.
Quintesson No. 1, Quintesson No. 2: Heh heh heh heh.
Shockwave: Identify yourselves!
Swindle: Some refer to us as Combaticons, but...
[Combaticons transform into... ]
MindWipe: The powers of darkness are greater than anything your pathetic scientific toys can muster.
Brawn: [hefts Megatron's cannon] Let's see how Megatron likes a dose of his own medicine.
[Fires it at Megatron and tumbles backward]
Brawn: Now that was a kick.
Brawn: [Laserbeak swipes the cannon from Brawn] Bring that back, you birdbrain!
Megatron: [Laserbeak drops the cannon onto Megatron's arm] No one does that to me, and continues to function!
[fires at Brawn]
Galvatron: Predacons, merge to become Predaking!
[Predacons transform into Predaking]
Galvatron: Predaking, I command you to destroy those scavenging invaders.
Sweeps: My guidance system has been hit! Galvatron, help me!
Galvatron: Please meet your end with dignity. I despise whiners.
Sweeps: This is blowing out my audio sensors! It's torture!
Galvatron: No! No! It's music! The Symphony of Destruction and the Anthem of Agony!
Silverbolt: [to Optimus Prime] Hi! I used to be a courier ship, but now I think I'm Silverbolt?
Air Raid: And I'm Air Raid!
Fireflight: Geez! What is this place? Who are you guys?
Optimus Prime: Who are you?
Fireflight: Oh, right. I'm Fireflight.
Skydive: I'm Skydive.
Slingshot: I'm Slingshot. Used to be a speed shuttle. Now I'm the fastest, smartest, hottest jet you ever saw!
Grimlock: You, Megatron, tricked us. Make us fight good leader, Optimus Prime. Prime risked own life to save us. Baaad Megatron!
Megatron: [rapidly] Decepticons, transform, quick, at once!
Dr. Archevil: Remember our agreement, Megatron: the Earth is to be mine once you are through with it.
Megatron: It will be. What's left of it!
Optimus Prime: Just remember, there's a thin line between being a hero and being a memory.
Motormaster: [to Megatron] I'm Motormaster! I swear loyalty to you.
Dead End: I am Dead End. I guess I'll have to do what you say.
Breakdown: I'm... I'm Breakdown. I'll obey too.
Drag Strip: I am Drag Strip. I LIVE to obey.
Wildrider: I'm Wildrider, and I wanna bust somethin' up!
Megatron: Is there anyone brave - or stupid enough - to oppose us? This city is under martial law... and I am the marshal!
[after being hit by the Eurythma harmony]
Galvatron: What was that?
Soundwave: [sounding unusually touched] That... was heaven! The purest, most vibrant, most perfect harmony I've ever heard!
Sunstreaker: [after being shot at] Hey! That's a new paint job!
Starscream: Nobody turns his back on me!
[blasts Megatron]
Starscream: Decepticons, feast your eyes on your new leader.
[Megatron awakens and kicks Starscream to the ground]
Starscream: What the...? Megatron! You're... you're dead! I terminated you!
Megatron: Fool. I can not be terminated by a single blast from your puny weapon. I'm sick of your endless quest for power. Especially at the cost of losing mine!
Starscream: [to Decepticons] Don't just stand there! DO something! Your new leader orders you to slay Megatron!
Megatron: You're a fool Starscream if you think anyone would follow your orders.
Starscream: Just wait Megatron. One of these days I will have my revenge.
Megatron: You and what army?
Starscream: It looks like some kind of... rust!
Megatron: Impossible! We are rust-proof!
Starscream: Perhaps you're made of shoddy materials, Megatron!
Megatron: That's ABSURD!
Starscream: [in Cyclonus' body] So, you think Galvatron's nothing but slag iron now?
Octane: Yeah, we've seen the last of that creep!
[Galvatron enters the room]
Galvatron: Seen the last of who, Cyclonus?
Starscream: [in Cyclonus' voice] Er, no-one really, sir, I mean...
Galvatron: You mean what, old friend?
Starscream: [in his own voice] Well now, who do you think I mean?
Galvatron: Starscream!
[Starscream laughs while Octane runs off]
Galvatron: [smiling] I shall enjoy destroying you even more this time than the last.
Starscream: Destroying me was a great disservice to all Decepticons!
[Galvatron transforms into cannon mode and blasts Cyclonus as Starscream's ghost flies off]
Cyclonus: What happened to me? Last I remember I was in the Decepticon crypt, and uh...
[Galvatron transforms into robot mode as Scourge and his Sweeps approach]
Galvatron: I hope I've seen the last of that miserable usurper.
[to Scourge]
Galvatron: See that Cyclonus is properly repaired.
[walks off]
Scourge: Of course, Galvatron.
[Starscream is revealed to be possessing Scourge's body and laughs]
Ironhide: Stop talkin', tighten your shock absorbers and get in. We're gonna make a new river.
Quintesson Commander: Besides, how can you be so sure we are the ones who betrayed you?
Galvatron: Well... you all do look alike...
Rodimus Prime: Last big party of the summer, folks! Let's go out with a bang!
Ultra Magnus: Just once, couldn't your attitude reflect the gravity of the situation?
Rodimus Prime: Not if I can help it!
Optimus Prime: Give it up, Megatron!
Cyclonus: He must be hiding in the crypt.
Scourge: Good... then we won't have to take him anywhere when we're done.
Blaster: We're outgunned, man! We don't have a chance!
Kup: Boy, that's what makes life interesting!
Rodimus Prime: Or OVER!
Crosshairs: We gotta stop our guys from destroying the thing that could wipe out the galaxy, and we gotta to straight into Deceptiville to do it!
Hot Rod: Yeah, we never seem to get a break.
Megatron: Power flows to the one who knows how. Desire alone is not enough.
Sky Lynx: Save your ammunition, Autobots! Superior forces are taking over!
Springer: Well, well, Commander Modesty's here!
Optimus Prime: We can't stand by and watch the destruction of this beautiful planet.
Blitzwing: Sometimes it's better to be known for one's enemies.
Ironhide: What did you do to Gears? You turned him - nice!
Optimus Prime: If a new source of energy is not found, no one is going to win this war.
Galvatron: Now, Decepticons, learn the price of your disloyalty! Attack!
Cyclonus: Attack whom?
Galvatron: [shouts] Everyone!
Dirk Manus: Slimy, worm-fingered creep!
Quintesson: Unlikable, dry-skinned biped.
Apeface: Yuck. Noble Autobots make me wanna puke.
Trypticon: Trypticon cannot be stopped! Nothing can stand in my way!
Optimus Prime: That tidal wave will devastate and destroy mankind across the face of the globe!
Ironhide: It won't do us any good either.
Optimus Prime: [from a trailer] Heroes never die. I, Optimus Prime, can never be conquered.
Metroplex: This planet's not big enough for the both of us!
Trypticon: [growls] Crush Metroplex!
