Editing Megatron (section)

===Films===
Megatron appears in ''[[Transformers (2007)|Transformers]]''. Megatron was the leader of the Decepticons in a war against the Autobots. Megatron has located the AllSpark on [[Earth]], but he crash lands during the [[Ice age|Ice Age]] and becomes frozen due to the Earth's magnetic field interfering with Megatron's [[telemetry]]. Megatron's body was discovered by Captain [[Archibald Witwicky]] and is transported to the [[Hoover Dam]] guarded by Sector 7, a secret government organization that studies Non-Biological Extraterrestrials (N.B.E.), as well as other alien-related activities.

Megatron was studied, and his technology was reverse-engineered to advance human technology. Megatron's location, as well as the AllSpark's, is located by a group of Decepticons led by Starscream. [[Frenzy (Transformers)#Transformers|Frenzy]] thaws out Megatron, who escapes outside and learns from Starscream that the humans and the Autobots have taken the Allspark. Megatron pursues the Autobots and their allies where he kills [[Jazz (Transformers)|Jazz]] before battling Optimus Prime. After being weakened by human fighter jets, Megatron attempts to seize the AllSpark, but [[Witwicky family#Samuel James Witwicky|Sam Witwicky]] shoves it into his exposed spark chamber, killing him. Megatron's body is later dumped into the [[Laurentian Abyss]], along with the other dead Decepticons.

In ''[[Transformers: Revenge of the Fallen]]'', he is revealed to be the Fallen's disciple, the first Decepticon. Megatron is revived by [[Scalpel (Transformers)#Transformers: Revenge of the Fallen|Scalpel]] and the [[Constructicons#Transformers: Revenge of the Fallen|Constructicons]] with an AllSpark shard. He then flies to the [[Nemesis (Transformers)|Nemesis]], where he is greeted by [[Starscream]] and then reunites with the Fallen, telling of the AllSpark's demise before being told by his master that its knowledge (which has been passed on to Sam) is the key for providing Energon, which the Decepticons need to awaken their protoform armies. Sam, his girlfriend [[Mikaela Banes]], and his dorm mate Leo Spitz are abducted by [[Grindor#Transformers: Revenge of the Fallen|Grindor]]. Before the Decepticons can extract Sam's brain, the Autobots rescue them. Megatron chases after Optimus and Sam in a forest, with Starscream and Grindor joining the battle. Megatron kills Prime but then is forced to escape due to the intervention of Autobot reinforcements.

Megatron and Starscream soon arrive in [[Egypt]], and he commands his Decepticons to prevent Sam from getting the [[Matrix of Leadership]] to Optimus and retrieve it for the Fallen's machine. He then summons [[List of The Transformers (TV series) characters#Constructicons|Devastator]], who destroys the top part of the [[Great Pyramid of Giza]], revealing the Star Harvester. The Fallen soon arrives and takes the Matrix from a recently revived Optimus. [[Jetfire#Transformers: Revenge of the Fallen|Jetfire]] sacrifices himself to give Optimus his parts, and then Megatron, and the Fallen battle Optimus. Optimus severely wounds Megatron and kills the Fallen. With his master dead, Starscream advises that they should retreat. Megatron does so but vows that the war isn't over.

Megatron returns in ''[[Transformers: Dark of the Moon]]''. In the four years since the events of ''Revenge of the Fallen'', Megatron has been hiding out in [[Africa]] healing his wounds, and taking care of the hatchlings.<ref>{{cite web|last=Bierly |first=Mandi |url=http://insidemovies.ew.com/2011/02/11/transformers-3-hasbro-toys |title='Transformers' 3 clues found in new Hasbro toys – EXCLUSIVE |publisher=Insidemovies.ew.com |date=2011-02-11 |access-date=2013-11-04}}</ref> In the film, it is revealed that Megatron allied himself with [[Sentinel Prime (Transformers)|Sentinel Prime]] in an attempt to revitalize Cybertron. Soundwave and [[Laserbeak]] inform him of the Autobot's discovery of the ''Ark'' ship on the moon and orders them to kill their human allies. When Sentinel betrays the Autobots, he transport Decepticon forces from the Moon to Earth and invade [[Chicago]]. Sentinel overthrows Megatron and becomes the leader of the Decepticons. Megatron is convinced by [[Carly Spencer]] that Sentinel will take all of the power and credit for himself. Angered, Megatron turns on Sentinel and severely damages him. When Cybertron is destroyed by the Space Bridge, Megatron proposes a truce to Optimus. Knowing that Megatron would betray him, Optimus refuses and finally kills him.

In ''[[Transformers: Age of Extinction]]'', despite being destroyed, Megatron's mind is still alive inside his severed head. Megatron's remains are acquired by KSI, who attempts to forge their own Transformers with "transformium". Their CEO, Joshua Joyce, forces [[Brains (Transformers)|Brains]] to download information from Megatron's head, which the Decepticon leader silently allows so Joshua will gain the information needed to succeed, which will grant Megatron access to a new body. Megatron then infects and possesses the unit '''[[Galvatron#Transformers: Age of Extinction|Galvatron]]'''. He then pretends to obey orders, only to finally defy his creators at the film's climax and accept his new identity as Galvatron and rebirth.

Megatron returns in ''[[Transformers: The Last Knight]]'', having discarded his identity as Galvatron. He is in league with Quintessa, the creator of Cybertronians. When Barricade reports that Cade Yeager has received the talisman from the Cybertronian knight Steelbane, he decides to use the TRF (Transformers Reaction Force) to lead him to Cade. Megatron then goes after Cade, but Cade and his companions lure Megatron into a trap, killing all the Decepticons except him, Barricade, and Nitro Zeus. Forced to retreat, Megatron later sends Barricade after Cade and Bumblebee, but his plan is thwarted, and he instead follows Cade, Bumblebee, and Viviane Wembly to the submerged ship of the Knights of Iacon, where Quintessa's Staff of Life, once wielded by Merlin, is hidden. When Optimus Prime steals the staff as Nemesis Prime, Megatron steals it himself and takes it to Stonehenge, where he uses it to open a portal that will allow Quintessa to destroy the Earth and face off against the Autobots and Optimus. Megatron is defeated by Optimus and is kicked out of Quintessa's chamber.
