The story of Megatron from the Transformers Cinematic Universe.

IDW Publishing Prequel Comics

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, serving as Lord High Protector. Megatron and Optimus learned of an alien force coming to their planet for the All Spark, just as a mysterious artifact was unearthed. 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 All Spark, and under the Fallen's influence, forms the Decepticons, sending the bulk of his soldiers in a craft, the Nemesis.

The Autobots attempt to hide the All Spark, but Megatron sees through the ruse and launches a full-scale attack, during which the All Spark is launched into space. Megatron almost catches up with the All Spark 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 the live-action film, Megatron was the cause of Cybertron's destruction when the Decepticons and Autobots have started a war that has destroyed much of Cybertron. The All Spark was fought over by both sides until it was lost in space, then landed on Earth at an unknown time, then humans found the cube and a human organization that investigates extraterrestrials called Sector 7 kept the All Spark in its' base for over a century. Megatron followed the All Spark to Earth, but crash landed in the Arctic where Captain Archibald Witwicky and his crew of men were. Captain Witwicky fell in an arctic hole and found Megatron who was frozen. But when Captain Witwicky touched the tip of Megatron's fingers, he also re-activated Megatron's navigation system, and Megatron (still frozen) flashed his eyes that imprinted the All Spark's location onto Captain Witwicky's eye glasses. The Decepticons and Autobots searched for the eye glasses when they found it on the web site eBay. Sector 7 took Megatron who was still frozen to the same base where the All Spark was.

When Decepticons Frenzy and Starscream freed him, he rose again and went into Mission City fighting the Autobots. Decepticons Blackout, Brawl, and Starscream where also in battle against Autobots Optimus Prime, Bumblebee, Ironhide, Ratchet, and Jazz. He killed Autobot officer Jazz by ripping him in half. Soon afterwards, Optimus Prime came in and the two long-time rivals fiercely dueled each other. Megatron and Optimus fought over their opinion of the human race: Megatron believed humans didn't deserve to live, while Optimus believed that humans deserved to choose for themselves. Hearing this, the rage-filled Megatron ordered Optimus to join the human race in extinction and tossed him aside. Megatron then formed his fusion cannon, but before he could fire, Optimus fired a shot from his ion blaster, hitting the Decepticon in the shoulder. Megatron shrugged off this attack and fired his fusion cannon, sending Prime flying into a building.


Megatron's first death.

With Optimus knocked out, Megatron was able to chase Sam Witwicky when he carried the All Spark that gotten much smaller because of Autobot Bumblebee touching it. Megatron stalked him through a tall building, with Starscream destroying the helicopter that was supposed to carry Sam. Megatron offered Sam a chance to live "as his pet," if he gave him the cube, but Sam refused. Angered, Megatron used his flail to knock Sam off the building. Unfortunately, the human was saved by Optimus, who then re-engaged Megatron. Blackout attempted to aid Megatron in defeating Optimus, but was destroyed by the US Army. The Air Force then blasted several missiles and human soldiers used guns to shoot sabot rounds at Megatron. Despite suffering damage, Megatron could not be killed by human weaponry. Megatron attempted one last time to attack Sam, but the human pushed the All Spark into Megatron's chest, and the Decepticon was finally destroyed.

Afterwards, the bodies of Megatron, Blackout, and Brawl were dumped into the Laurentian Abyss.

The Reign of Starscream

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.

Transformers: Revenge of the Fallen


Megatron's revival in the second film.

In the film, Megatron was resurrected by the Constructicons Long Haul, RampageMixmaster and Ravage using a stolen piece of the All Spark. It is revealed that Megatron was in second place leader and apprentice of The Fallen, who is the true founder and leader of the Decepticons. It also turns out that the reason why Megatron is so ruthless and power-hungry is because the founder of Decepticons corrupted him into serving him, thus making the Fallen responsible for the war between the Decepticons and Autobots that destroyed much of Cybertron. Though Megatron remains very powerful, he is not as strong as he was in the first movie, because his original body parts were unusable since he was killed off by the AllSpark before being brought back to life. Instead, much of his original body parts were replaced by the parts of a relatively weak Decepticon, named Scrapmetal (called "ze little one" by The Doctor).

Upon being resurrected, Megatron headed to the crashed Decepticon ship, the Nemesis. There, Megatron was reunited with his master, who ordered Megatron to capture Sam Witwicky as the human now had some information placed into his mind by a shard of the All Spark, and to kill Optimus, who, being the last living Prime, was the only Transformer who could defeat The Fallen. Megatron then ordered Grindor to capture Sam. Grindor then captured Sam and his friends and brought them to an abandoned factory. Megatron then started to interrogate Sam until Optimus and Bumblebee arrived to save Sam and his friends. Megatron and Optimus briefly dueled in a cannon-fight, when Optimus used a cannon to blast the Decepticon through several walls, into the open.

Megatron then chased Optimus and Sam until he caught up with them. Megatron and Optimus then battled violently through a forest, ripping through several acres - even using them as melee weapons. However, whilst Megatron's durability was enough to withstand Optimus's missiles, he was not physically enough to match the Prime in a fight. Therefore, Optimus quickly got the upper hand and Megatron called upon Starscream and Grindor to help him. Despite being outnumbered, the Autobot leader eventually managed to fight off all three Decepticons, stabbing and punching Megatron multiple times, severing Starscream's right arm, and killing Grindor by ripping his head apart. However, as a weary Optimus tried to find Sam (who had been hiding during the battle), Megatron caught Prime off-guard and stabbed him in his spark core, killing the Autobot leader. He and Starscream then retreated when Autobot reinforcements arrived.

With Optimus Prime now dead, Megatron was quite pleased until Starscream informed him that they lost Sam. Furious with his lieutenant's failure to capture a simple "insect," Megatron brutally tortured his lieutenant. Starscream then replied that there were seven billion insects on the planet and Sam was just one among them and that he could be anywhere. Megatron then decided to force the humans into finding Sam for the Decepticons and also decided to come out of hiding and reveal their existence to the Earth. He then broadcasted a message from the Fallen by using the Empire State Building's radio tower. He and the Decepticons then headed to Egypt where the Sun harvester, a machine used to harvest Energon out of suns hidden was in a one of the pyramids of Giza. Starscream then informed Megatron that Autobots and humans had brought Prime's body. Megatron then realized that Sam had the Matrix of Leadership and can revive Optimus with it. Megatron told Starscream that they cannot let Sam get to Optimus, then ordered the Decepticons to begin their assault.

Megatron then took part in the battle against the Autobots and nearly killed Sam, but then he was suppressed by human firepower and was forced to retreat. Megatron was then seen on top of the pyramid, and watched as The Fallen activated the Sun Havester. However, a revived and super-powered Optimus, now fused with Jetfire, destroyed the Harvester and knocked Megatron and the Fallen off the pyramid. The three Transformers battled destructively, but Optimus eventually gains the upper hand. Megatron attacked Optimus from behind in an attempt to help his master. However, he was quickly overwhelmed and got half of his face blown by his own fusion cannon. Optimus then severed Megatron's right arm with his energon sword and used his afterburners to send Megatron flying through a wall. Megatron, being severely damaged, called out to Starscream for help and then watched helplessly as the Fallen was slain by Optimus. Seeing this, Starscream suggested that he and Megatron retreat, to which he agreed, but vowed that "This isn't over".

Transformers: Dark of the Moon

Cybertron… you are saved, at last.
~ Megatron
Megatron severely weakened by the injuries he sustained fighting Optimus Prime in Egypt, Megatron was revealed in Transformers: Dark of the Moon to be hiding in the African Savannah along with Starscream, Soundwave, Igor and Laserbeak, currently serving as the new leader of the Decepticons after death Fallen. Unable to challenge Optimus directly, Megatron arranged for Shockwave to reveal the location of a long lost Autobot ship, the Ark, to the Autobots, as well as its captain, Optimus' mentor and former Autobot leader Sentinel Prime, on Earth's moon. Unknown to Optimus, during the war on Cybertron, Megatron had convinced Sentinel to betray the Autobots under the pretense of ending the war for the sake of preserving their homeworld. In order to do so, Megatron and Sentinel Prime plotted to use a space bridge to transport Cybertron into Earth's Solar System, intending to use the humans as slaves. However, shortly after Sentinel's treachery was revealed, Megatron himself was betrayed by his alleged ally as Sentinel secretly overthrew him and took command of the Decepticons for himself.

Megatron's second death.

During the Decepticon attack on Chicago, Megatron lay on a throne of junk, sulking over being overthrown by Sentinel yet relieved Cybertron was reviving. Sam's girlfriend Carly Spencer, arrived and pointed out to Megatron that as long as Sentinel was around, he would be less than nothing, saying to Megatron that in the end, he would became the Sentinel's "bitch." This goaded Megatron into action; just as Sentinel was about to deliver the deathblow to Optimus, Megatron turns against Sentinel by viciously attacking and wounding him, declaring Earth was "his" planet to rule. After seeing the space bridge being destroyed, Megatron tossed the crippled Sentinel aside and attempted to make a false truce with Optimus, mockingly asking Prime who he would be without him. But Optimus, knowing that the Deception leader would not give in so easily, responded "time to find out" and attacked Megatron, quickly tearing off his nemesis's head with a battle axe, finally killing him. Optimus then used Megatron's fusion shotgun to finish off Sentinel for your betrayal.

Transformers: Age of Extinction

Main article: Galvatron
That is why I have no fear!
~ Galvatron's most famous line to Optimus Prime

Megatron returns in the film, and is now known as Galvatron. Towards midway over the course of the film, he takes over the 50 man-made Transformers and converts them into his new army, although he only has one battle with Optimus which is his only battle in the whole film and he retreats before he is defeated.

Unknown to all, Megatron's mind actually survived his destruction and was in a stasis inside his severed head. A few years after the Battle of Chicago, KSI salvaged Megatron's remains, where CEO Joshua Joyce had them use it to create a new Transformer that intended to resemble Optimus Prime. However, unknown to any of the humans, their tampering re-activated Megatron's spark within, and he began to influence the humans to create an entire army of Transformers so he would eventually hack them and rebuild his Decepticon army. He also learned of an ancient Cybertronian weapon called a "seed" which could cyberform an entire city on its own. He planned to take the seed for himself, desiring to use it to destroy Hong Kong and build more Decepticons. Megatron eventually took over the body of a KSI transformer, Galvatron, accepting the name as his new identity. Although Galvatron intended to steal the seed, he pretended to be a remote-controlled drone for the time being.

Galvatron was first unleashed when he was ordered to chase Optimus Prime and his allies - human and Autobot alike. He pursued them along the outskirts of Chicago, before transforming into Decepticon form to attack them. He launched a series of missiles at the Autobots, going on a rampage and deliberately massacring human civilians - he had originally been designed to be under Joshua Joyce's control but had broken free completely. The humans are horrfied at what Galvatron is doing, as they did not programme him for this. After removing several Autobots, and the humans, from the battle, Galvatron came face to face with Optimus Prime.


Galvatron revealed his true identity.

An intense brawl broke out, destroying much of the road. Every single attack Optimus executes is effortlessly, violently and furiously redirected against him by Galvatron. The two Transformers' fighting forces the human Tessa into cover, and every single time she tries to escape the fight accidentally obstructs her, pinning her down. In a desperate attempt to end the fight, Optimus Prime stabs Galvatron in the chest, but when the blade hits home, it is shredded - Galvatron has no soul, and thus has no fear. After Optimus exclaims at this, Galvatron sneers at him - actually speaking, which renders the humans at KSI speechless and incredulous. After this, Galvatron easily gains the upper hand on the Autobot, becoming more violent and unpredictable even for Optimus. However, the fight is inadvertently ceased when Lockdown appears and disables Optimus Prime. After this, Galvatron is immediately pulled back.

Galvatron later freed himself permanently, but not before he controlled the other fifty Transformers in KSI's facility in Hong Kong so they became his new army. However, the new Decepticon army was destroyed. In the end following the deaths of Harold Attinger and Lockdown, Galvatron was forced to retreat with his remaining minions and claimed that he and Optimus will meet again one day, as he left for parts unknown.

Transformers: The Last Knight

~ Megatron to Optimus while battling him, regarding on the fact they are brothers.
Megatron returns in Transformers: The Last Knight, returning to his original name. In this film, he dons new battle armor including a helmet that partially covers his mouth as well as an arm cannon and sword, making him even more powerful than before and likely the strongest he's ever been. He now transforms into a Cybertronian jet, like in the first film. He also fights his twin brother Optimus Prime again just like in the previous films.

Though this is never seen or mentioned in the film, Galvatron fell under the sway of the alien sorceress and supposed Cybertronian "goddess" Quintessa, who most likely reformatted his body into something parallel to his former self, complete with a new jet alternate mode. Quintessa charged him with recovering the staff stolen from her by her Guardian Knights, which she sought to use to drain the lifeforce of Earth in order to restore the ruined Cybertron. Learning from his new ally that Earth was, in fact, Cybertron's ancient enemy Unicron, Megatron surveyed each of the six mountainous "horns" that had begun to emerge from its surface in preparation for Cybertron's arrival.

Megatron first appears when Barricade reports to him that Cade Yeager has found the mysterious talisman they're seeking. Megatron contacting TRF abducting two CIA agents and offered an exchange to release his group of Decepticons. Megatron arrives in the desert with William Lennox whom he strikes a deal: the realization of his fellow Decepticons Mohawk, Nitro Zeus, Dreadbot, and Onslaught (after he was denied Berserker) in exchange for him killing Yeager, Izabella and the Autobots. Megatron and his team then go off to find them.

Later, Megatron and his Decepticons arrive at Yeager's junkyard and attack the Autobots. Megatron finds the head of Starscream and picks it up to tell him that the end was near and that it is a shame he is not there to see it. During the ensuing chaos, thought most of his warriors are killed except Nitro and Barricade, Megatron manages to seize Squeeks (Izabella's Transformer friend) and sadistically prepares to tear him apart, before being confronted by an angry Izabella who orders him to put Squeeks down, saying she is not afraid of him. Fortunately, Yeager causes an explosion under the Decepticons' feet, leading them to briefly lose balance and allowing Yeager, Izabella, Squeeks and the rest of the Autobots to escape.

During the attack on Earth by Optimus's creator, Quintessa, Megatron flies in with Nitro Zeus just after Optimus is broken free from the sorceress' control and seizes the staff from Optimus, telling him that he turned his back on Cybertron for the last time and that he will now watch as Earth dies before escaping with the staff.

At Stonehenge, Megatron works with Quintessa and uses the staff to activate the machine, controlling Cybertron. As the British military intervenes, Megatron shoots Burton, who dies by Cogman's side. Optimus then unites the Knights with the Autobots and the military. Using Lockdown's ship, they set off to stop Cybertron's collision with Earth. They raid Cybertron and battle against the Decepticons and Infernocons, Quintessa's soldiers. Optimus Prime destroy the Infernocons and guide Viviane and Cade so they can get to the staff. As Quintessa commences Cybertron's resurrection, the Autobots fight against Megatron. During the time, Megatron's upgraded body proves to be more than a match for the combined Autobot forces. He nearly kills Hound with his axe-sword before Hot Rod uses his special gun that shots bubbles used to briefly stop time, allowing Hound to shoot Megatron with his gun, to which he angrily fights back with his fusion-cannon. Bumblebee then jumps on Megatron's back but is quickly thrown off.



Fortunately, as Megatron prepares to shoot him with his fusion-canon, Viviane is about to take the staff from Quintessa, and in desperation Quintessa calls out to Megatron to kill Viviane while she herself is unable to. Before he can vaporize her, Optimus cuts off his arm. The Decepticon leader then head-butts Prime in the head and pins him to the ground, angrily reminding him that they were brothers once, to which Optimus replies "Once" before kicking Megatron out, sending him flying back to Earth in the process, allowing Optimus and Bumblebee to easily defeat Quintessa. It is unknown what happened to Megatron following Quintessa's defeat and exile to Earth.
