Editing Megatron (section)

===Comics===
====IDW Publishing====
The back story of Megatron is told in both ''Transformers: Defiance'' and issue #1 of the ''[[Transformers: Movie Prequel]]'' comic. In the comics, Megatron is revealed to have co-ruled Cybertron together with [[Optimus Prime (other incarnations)#The Transformers|Optimus Prime]], serving as Lord High Protector. Megatron and Optimus learned of an alien force coming to their planet for the Allspark, just as a mysterious artifact was unearthed.<ref>{{cite web|url=http://www.comicscontinuum.com/stories/0901/15/idwfirsts.htm |title=Comics Continuum |publisher=Comics Continuum |date=2009-01-15 |access-date=2013-11-04}}</ref> Megatron is gravely injured, but the artifact (containing the Fallen) awakens and heals him, swaying him with promises of power. Megatron soon desires power over the Allspark, and under the Fallen's influence, forms the [[Decepticon]]s, sending the bulk of his soldiers in a craft, the ''[[Nemesis (Transformers)|Nemesis]]''.

The Autobots attempt to hide the Allspark, but Megatron sees through the ruse and launches a full-scale attack, during which the Allspark is launched into space. Megatron almost catches up with the Allspark as it lands on [[Earth]]. In his reckless desire to possess it, Megatron pursues it right into Earth's atmosphere and falls into the icy waters, resulting in his being frozen in stasis lock. In the late 19th century, Captain [[Archibald Witwicky]] discovers the Decepticon during an Arctic expedition. At the turn of the 20th century, a crew of men later take his body—dubbing him the "ice man"—and keep him in storage up until the present day, eventually relocating him to [[Hoover Dam]] in Nevada.

In a flashback in the movie sequel comic ''[[Transformers: The Reign of Starscream]]'', Megatron's negative relationship with [[Starscream]] is shown to be a result of Starscream failing on a mission.

====Titan Magazines====
All events that take place in the alternate reality where Megatron won the battle at Mission City are in italics.

In [[Titan Magazines]]' [[Transformers (comics)#Titan Magazines|''Transformers'']] magazine, the UK-originated strips (written by Simon Furman) reveal Megatron's actions between issues #1 and 2 of the IDW comic. Pursuing the Allspark into space following the events of ''Movie Prequel'' #1, Megatron is delayed in his pursuit by a tractor beam from Cybertron. Breaking free and attacking the culprits—Jazz, Ratchet, and Ironhide—Megatron realizes that if he engages them, he would be delayed further. Summoning [[Brawl (Transformers)#Transformers (film)|Devastator]] to deal with them, he resumes his pursuit—but the desperate gamble works and he (temporarily) loses the Allspark's trail.

The character profile the magazine provided sheds a little more light on Megatron's desire to possess the Allspark. He believes that while Cybertronians could already transform into other forms via a scanning process, the Allspark could allow Transformers to simply imagine the form they want and change accordingly. Interfacing with the Allspark directly, Megatron gains his deadly jet mode and begins his plans to obtain it permanently.

In "Twilight's Last Gleaming" part 3, [[Bumblebee (other incarnations)#Transformers|Bumblebee]] attempts to take on Megatron in the Sector 7 base as Mikaela attempts to free Optimus Prime, but she is attacked by Frenzy. In part 4, Mikaela frees Prime and freezes Frenzy just as Autobot reinforcements arrive and assist Bumblebee in fighting Megatron.

====Cybertron's Most Wanted====
Yet another version of Megatron was featured in BotCon's 2015 "Cybertron's Most Wanted" storyline. This version featured a history virtually identical to that of the Megatron of the films, up until the final battle of ''Dark of the Moon.'' At this point, some force intervened to save Megatron from Optimus's killing blow, allowing Megatron to kill not only Optimus but Sentinel Prime as well. After rebuilding himself and conquering Earth, Megatron set out to reclaim Cybertron, only to be forced to contend with a new Autobot leader who proved to be an even more dangerous foe than Optimus: [[Rodimus Prime]]. Defeated and left hanging from the edge of a spacebridge, Megatron chose to abandon himself to fate rather than allow Rodimus to kill him, and wound up in the interdimensional city of Axiom Nexus, despite restrictions put in place by the Transtech to prevent versions of Megatron from taking up residence there. He soon formed a new gang of criminals including [[Maximal (Transformers)|Maximal]] thief Packrat, Decepticon Triple-Changer [[Battletrap]], Shattered Glass Autobot Stepper, and a trio of Microns.

====Sector 7 Adventures: The Battle at Half Dome====
In the ''[[Bumblebee (film)|Bumblebee movie]]'' tie-in comic, Megatron was frozen at the [[Hoover Dam|Igloo]] foreshadowing his appearance in [[Transformers (film)|The 2007 film]]
