"[after destroying a military base] Ah, I just love a smoking ruin, especially one I created. Decepticons, this is Starscream. Make to the rendezvous point. The AllSpark will soon be ours."

"[deploying Scorponok] Hunt and destroy."

"[to Ironhide] The AllSpark is mine, Ironhide."

"[to Ironhide] You'll never defeat us, Autobot. You're doomed to destruction."

"[to Ironhide] I will crush you, and then lay waste to this insignificant world."

"[pursuing Bumblebee] Can't run forever, Autobot!"

"[to Megatron] Lord Megatron, I have infiltrated the city. The human appears to have fled to this location with the AllSpark."

"[Opening narration] Our world, our once proud race, was torn apart by war. Two factions rose and fought for that which gave us life, the AllSpark. We, the Autobots, who are sworn to protect it, and those who desire its power for evil, the Decepticons. For centuries it has remained hidden. But now the safeguarding of the AllSpark has brought us here. This world will not be ready for our war, our warriors, but we have come. Our fates and the future of this world shall be decided here. One shall stand, one shall fall."

"[to Starscream and Blackout after being freed from Hoover Dam] Rise, Decepticons. We have much to do."

"[to Barricade through communicator] Get to the beacon and retrieve the AllSpark!"

"[to Barricade through communicator] Break him [referring to Jazz] to pieces. Claim the AllSpark for your Lord Megatron!"

"[to Scorponok through communicator] The AllSpark is emanating massive waves of Energon. Get to the beacon and the source of this waves."

"[to Scorponok through communicator] Find the humans and destroy them! Bring the AllSpark to me!"

"[to Scorponok through communicator] Eliminate the Energon drones."

"[to Blackout through communicator] Scorponok has reached the AllSpark, but he is encountering heavy Autobot resistance. Get to his location immediately."

"[destroying the city] Come out, Prime! If you hand over the AllSpark, I may spare these creatures [referring to the humans]."

"[destroying the city] Where are the Autobots to protect you now, flesh bags [referring to the humans]?!"

"[destroying the city] This city... this entire world... will burn beneath my feet!"

"[destroying the city] The glory of destroying the traitor Prime will be mine."

"[fighting Optimus Prime] I was beginning to wonder if you were ever going to come, brother."

"[fighting Optimus Prime] The AllSpark belongs to me!"

"[fighting Optimus Prime] Once I destroy the humans and acquire the AllSpark, you'll witness the true meaning of terror."

"[fighting Optimus Prime] You barely stopped me on Cybertron. And you shall not stop me here!"

"[fighting Optimus Prime] I'll crush the Spark from you with my bare hands, Prime!"

"[fighting Optimus Prime] Your pathetic love for this planet will be your undoing, Prime!"

"[fighting Optimus Prime] Victory is mine! Death is yours!"

"[Closing lines, after conquering Earth using the power of the AllSpark] Finish this planet. We are done here."

"[to Jazz] Step aside, Autobot. The AllSpark belongs to Megatron. I will exterminate the humans and claim it now."

"[to Bumblebee through communicator after he arrives on Earth] Bumblebee, this is Prime. Our connection to the AllSpark is located somewhere within that human settlement. Discover what you can and report back to me. [Decepticon drones appear] Decepticons! Find a form. [Bumblebee scans a second-generation Chevrolet Camaro and transforms into his new alternate mode] Stop the Decepticons before they find the connection to the AllSpark. Stop them at all cost."

"[to Bumblebee through communicator after defeating the Decepticon drones] The Decepticons have found a Transformer code linked to Megatron. It is currently in possession of a human named Sam Witwicky. We must reach him before the Decepticons."

"[to Bumblebee through communicator to find Sam] Get to the residence of Sam Witwicky. If he has the artifact then you'll have to reach him before the Decepticons do."

"[to Bumblebee through communicator after finding Sam Witwicky] It's up to you to protect Sam Witwicky and the artifact from the Decepticons. Head for the high school and keep a close watch on him. Remain vigilant."

"[to Bumblebee through communicator while fighting Barricade] Bumblebee, you must hold off Barricade while Sam and Mikaela escape."

"[to Bumblebee through communicator after defeating Barricade] Bumblebee, good work finding the human. He has the artifact that will lead us to the AllSpark. You must protect him at all cost."

"[to Sam and Mikaela] My name is Optimus Prime and we need your help."

"[after hearing passing helicopters] Transform and roll out!"

"[to Ironhide through communicator] Ironhide, get to Jazz! He's been cornered by Sector 7!"

"[fighting Shockwave] Shockwave. I've got to take him out, before he levels the city."

"[fighting Shockwave] I can't let him get away."

"[fighting Shockwave] You'll not cause any more destruction, Decepticon. [referring to Shockwave]"

"[fighting Shockwave] Nothing will stand my way."

"[discovering Starscream while decoding Shockwave's transmissions] Starscream. [to Ratchet and Jazz] Our mission now is clear! Locate the AllSpark and find Bumblebee, Sam and Mikaela! Autobots, transform and roll out!"

"[to Bumblebee through communicator inside Hoover Dam] Glad to have you back in action, Bumblebee. It seems that the AllSpark is watching over you. Head to the beacon for your mission objective."

"[to Bumblebee through communicator after he finds Megatron frozen inside Hoover Dam] Megatron! Bumblebee, you must prevent him from acquiring the AllSpark! Our fate, the fate of all Autobots, the fate of the galaxy is in your hands! I know you won't fail us."

"[to Ironhide through communicator] We have lost contact with Bumblebee and the AllSpark. Investigate immediately."
