~ Megatron

Megatron, later known as Galvatron, is the main antagonist of the Unicron Trilogy (alongside Unicron himself) of the Transformers franchise, comprised of the three anime television series; Armada, Energon, and Cybertron. The leader of the Decepticons, Megatron fights against the Autobots to gather the Mini-Cons scattered around the galaxy so he can use their power to take over.

He was voiced by David Kaye, who also played Beast Megatron in the Beast Era, such as Transformers: Beast Wars and Transformers: Beast Machines, and The Stretch Monster in the 2nd season of Stretch Armstrong and the Flex Fighters.




Transformers Armada Optimus prime and Megatron Cybertronian Forms

Megatron and Optimus Prime's first encounter in Transformers Armada

After a signal from the missing Mini-Cons was detected Megatron led a squad of Decepticons including Starscream, Cyclonus, and Demolishor to Earth in the year 2010. In First Encounter, he met three human children who had befriended the Mini-Con High Wire. After demanding the Mini-Con, Megatron battled Optimus Prime, and in Metamorphosis, the rest of their troops arrived. Eventually, the Decepticon leader called for a strategic retreat. The Decepticons withdrew to Earth's moon to investigate the portion of the Mini-Con ship that landed there, which they used as their base, and Megatron discovered his old Mini-Con partner, Leader-1. With the Mini-Con giving him an edge over the Autobots, Megatron had his forces take new vehicle modes and led them back to Earth. The Decepticons targeted the three human children from before, who had since awoken the Street Action Mini-Con Team, but the Autobots thwarted them.

On Earth, Megatron led his Decepticons in fighting the Autobots for possession Mini-Cons. Megatron eventually managed to obtain the first two Mini-Con weapons, the Star Saber and the Skyboom Shield. Thanks to his tactician, Thrust, Megatron was able to obtain the final weapon, the Requiem Blaster, which he combined with the other two to build the Hydra-Cannon. Megatron fired the weapon at Earth, but Optimus Prime took the blast to save the planet, killing himself in the process.

Prime's death plunged Megatron into a deep depression, having lost his greatest opponent without the chance to finish him with his own hands. However, the Mini-Cons were eventually able to resurrect Optimus. Megatron was later among the Transformers who had their powers boosted by their Mini-Cons after being attacked by Nemesis Prime, becoming Galvatron and returning to Cybertron with a renewed vigor for conquest.

Despite the emergence of Unicron Galvatron ignored the threat, forcing his lieutenant Starscream to sacrifice himself to make his leader see the truth. Realizing the threat Unicron posed to the universe, Galvatron rallies all the Decepticons to ally with Optimus and the Autobots to stop Unicron for good. Galvatron entered Unicron's body along with Optimus Prime and traveled to the center of it. They were absorbed into the chaos god's body and mind, but when the Autobots' human allies freed the Mini-Cons from Unicron's thrall, Galvatron too was freed. Believing the threat of Unicron was over, challenged Prime to a final duel. However, the energies released in the battle reawakened Unicron. Galvatron believed that the only way to end the circle was to destroy himself and so he chose to sacrifice his life rather than live in an era of peace, plunging himself into Unicron's maw. In a flash, the two were seemingly destroyed.


Although he was believed dead by both the Autobots and Decepticons, Megatron, like Unicron, had survived the final battle. However, his body was a decayed husk absorbed into the equally damaged body of Unicron. Megatron lay dormant within Unicron for ten years until the being called Alpha Quintesson began his plan to re-energize Unicron. Seeing an opportunity, Megatron siphoned off some of the Energon that Alpha Q's Terrorcons stole, working towards his rebirth. To turn the Decepticons to his side, Alpha Q forged a sword from Megatron's spark, but when an enraged Scorponok stabbed Megatron's corpse with the blade, Megatron was fully revived. Taking the sword for his own, Megatron proceeded to take control of Unicron's body, sending Alpha Q fleeing in Unicron's head. Megatron thus restarted his campaign against Earth and the Autobots, seeking Energon to reactivate Unicron so he could use him as the ultimate weapon.

Megatron eventually succeeded in bringing Unicron to the vicinity of Cybertron and transforming the planet-eater to robot mode. However, in an attempt to stop him, Alpha Q rammed Unicron's head, charged with the positive Energon of Earth, into Unicron's body. This triggered a reaction that tore a rupture in reality that led to a new region of space where Alpha Q recreated all the planets Unicron had consumed. Megatron immediately saw these new worlds as targets to acquire more Energon, and after another series of attacks, Megatron successfully amassed enough to fully reanimate Unicron. However, the chaos bringers consciousness to invaded Megatron's body, taking over his mind.

Although Optimus Supreme was able to destroy Unicron's body, Unicron's mind lived on within Megatron, subtly directing him to attack Cybertron and uncover a reservoir of Super Energon beneath the planet's surface. Megatron immersed himself in the powerful liquid, causing him to assume a more powerful form, once again taking the name of Galvatron. Taking control of the planet, he forced the Autobots underground with Energon gas and used the planet's Energon Towers to relocate Cybertron to Alpha Q's region of space. Once there, Galvatron once again coated himself with Super Energon, causing growing to a colossal height. However, it was at that point that Unicron's influence seized control of his mind and directed him out into space to re-emerge with his spark. Optimus Prime went battle the Unicron-possessed Galvatron and, after Galvatron's hatred of Unicron caused his consciousness to surface again, Prime drained Unicron's influence from Galvatron and sealed it within himself.

Enraged by Unicron's manipulations, Galvatron decided to destroy Unicron's spark but wound up being possessed by it once more. While struggling to fight the control of Unicron, Galvatron was confronted by Optimus Prime once again. Rather than fight him, Galvatron instead flew into the foundling sun created by Primus, igniting the star and seemingly destroying himself rather than allow Unicron victory.


Ten years later though, the star would collapse, creating a black hole that threatened the existence of Cybertron and the rest of the universe. The collapse of the star also Megatron allowed his confinement within the sun. Megatron also merged his body with the remnants of Unicron's shattered form to increase his power with the energy of the dark god.

As the Autobots prepared to evacuate Cybertron in the wake of disasters caused by the black hole, Megatron stole a holographic map containing locations of the Cyber Planet Keys that could be used to seal the black hole from Vector Prime. Operating out of a fiery pocket dimension, Megatron schemed to used the world-shaping power of the Cyber Planet Keys and their focal Omega Lock to accelerate the universal degeneration created by the black hole, destroying the universe and using the keys to remake it in his image.

Leaving Starscream and Thundercracker to search for the Omega Lock on Earth, Megatron located the resting place of the first Cyber Planet Key on Velocitron, the Speed Planet. Recruiting Ransack and Crumplezone to his cause, Megatron deduced that the planet's racing trophy was the key. After failing to defeat the planet ruler Override in a race to learn more, he left Ransack and Crumplezone to compete in tournaments and win the trophy and turned his attention to the Jungle Planet, home of the second Cyber Planet Key, where he ingratiated himself with planet ruler Scourge. Both missions ultimately failed, however, when the Autobots acquired the keys.

Attempting to find the third key, Megatron discovered that he had been betrayed by Starscream, who switched out the planet map with a duplicate that led him to a dead sector of space and sealed him within a metallic sphere. Scourge was able to liberate him a short time later, but in that time, Starscream had obtained the third Cyber Planet Key from Earth for himself along with the Omega Lock and other keys. Megatron made a beeline for his treacherous lieutenant but was intercepted by the Autobots Hot Shot, Red Alert, and Scattorshot, who intended to hold him off until the other Autobots could stop Starscream. Starscream's attempts to harness the Earth Key caused a release of energies that gave Megatron a new Cyber Key power, the "Death Machine Gun," which he used to mow down the Autobots in his path.

The Autobots managed to retake the keys from Starscream, Megatron mounted another attack where he stole the keys and retreat into his pocket dimension. Prime pursued him through the portal and defeated him in a pitched battle, reacquiring the lock and returning to Cybertron. Megatron attempted to pursue him, but Vector Prime combined his portal-opening powers with the Cyber Planet Keys and collapsed Megatron's dimension in upon itself, resulting in Megatron's destruction.

However, the power of Megatron's Unicron armor caused him to return as a ghost-like entity composed of pure darkness. Megatron returned to Cybertron and used Unicron's reformatting powers to upgrade the injured Crumplezone into Dark Crumplezone. The Autobot Leobreaker attempted to attack him but was unable to stop him from completely restoring his physical body. Megatron then used the lingering darkness to create an evil doppelganger of Leobreaker, Nemesis Breaker, out of the Autobot's dark thoughts. Merging with Nemesis Breaker to form Dark Claw Mode, Megatron battled Optimus Prime and Leobreaker's Savage Claw Mode, until news of the location of the fourth and final Cyber Planet Key caused him to exit the battle.

Megatron and his party of Decepticons were guided through a spatial warp by the mysterious Soundwave to Gigantion, the Giant Planet, home of the final key. Megatron engaged the world's leader, Metroplex, for possession of the key only to be defeated in seconds. Consumed with rage, the power of Unicron within his armor reached out and detected the energies of the Giant Planet's Cyber Planet Key, drawing upon them and infusing Megatron's body with them. In his dark, shadowed form, Megatron decimated the Autobot forces before being confronted by Optimus Prime. Megatron then revealed his completed transformation - having once again become Galvatron.

After taking revenge on Metroplex, Galvatron went after the Giant Planet key. Though the Autobots were able to acquire the key, Galvatron managed to steal the completed Omega Lock soon after. Right after doing so though, Megatron was attacked by Starscream, and the two battled for possession of the artifact. Galvatron claimed a slim victory in the battle, with the sheer amount of energy released in the clash blasting Starscream, as well as Sideways and Soundwave, into another universe.

With the lock and keys now in his hands, Galvatron attacked Primus and returned to the Black Hole with his Decepticons, ready to destroy the universe with the Black Hole and recreate it anew. However, the Transformers from each of the five planets all got together and formed a coalition force to defeat Galvatron. In a massive battle, Galvatron was confronted by the five-planet leaders, who used their combined powers to defeat him. Realizing he couldn't win, Galvatron let go of Omega Lock with the Cyber Planet Keys in it to allow the universe to be destroyed by the Black Hole. However, the Autobots managed to retrieve the Omega Lock and the Cyber Planet Keys and return them to Primus, whose Spark was then restored and who used the Ark to finally seal the black hole for good.

Having had ultimate power torn from his grasp, Galvatron contemplated giving up. However, the spirit of Starscream then appeared before him to mock him for giving up, saying that if he was to give up just like that, then he was "no Unicron." Starscream's spirit then vanished, leaving his crown which came to Galvatron. Clenching the crown close, Galvatron realized that his former lieutenant was right and decided to continue his conquest to see to one last showdown with Optimus Prime. He attacked the Autobots' project to propel the Jungle Planet back into place via massive rockets and dented one of them, setting the course of the planet out of order. However, the combined power of the Transformers of the four planets, along with Megatron's former Decepticon lackeys, managed to move the rocket back into place. Meanwhile, Megatron challenged Optimus Prime to one final duel. Battling on Cybertron's moon, Galvatron generated a massive blade of dark energy, which Prime countered with Vector Prime's sword. As the two old enemies charged towards each other in a final strike, Prime impaled Galvatron through the chest, finally killing the Decepticon leader and causing him to dissolve away.

In a montage sequence after the series, however, Galvatron's evil proved eternal, as, beyond the veil of time and space, his spark battled with that of Vector Prime.

Transformers the 2002 game

Megatron appears in the 2002 transformers game as the main antagonist and boss. Here he has his own army called the Decepticlones where he uses it to conquer Cybertron and later attempts to conquer earth to collect the minicons.


You have something of mine.
~ Megatron after his arrival to Earth.
My power is your doom!
~ Megatron gloating.
You have an important decision to make! Say you'll join me or I'll let you slip away into the darkness. I, Megatron, am your only leader now. Say my name and I'll spare you. What is my name, Starscream? (...Megatron...) Say it again.
~ Megatron tortures Starscream into obeying him.
At last! The ultimate expression of my dark powers!
~ Megatron on Dark Claw Mode.
You see, Starscream, when you risk everything in the pursuit of power, you could wind up with nothing. That's why I never risk anything.
~ The victorious Galvatron mocks Starscream one last time.
I still function... you haven't won... not while my Spark still burns...
~ Galvatron's final words




  • This Megatron is the first incarnation of the character to use a tank alt mode in performed media.
    • Megatron's appearance in Armada looks very reminiscent to Generation 2 Megatron.
  • A Decepticon with Megatron's Cybertron look was seen in the Transformers Animated story Bots of Science.
  • Megatron seems to become increasingly twisted and evil over time; while he was abusive to his men in Armada, he cared about them in a twisted way, and ally with the Autobots against Unicron. In Energon, Megatron is far more ruthless, gleefully brainwashing his men, such as Starscream, Demolisher, and Cyclonus. back into loyalty when they had compunctions over willingly serving him, sought to use Unicron as a weapon. In Cybertron, he views his army as completely disposal, and plots to destroy reality, remaking it into his own image.
    • At least some of this could be due to the corruptive influence of Unicron, as he was trapped within his remains for ten years before Energon, and wearing the Armour of Unicron in Cybertron.
  • It seems Megatron becoming Galvatron is a repetitive cycle throughout the three series (at least in the English dubs). In the middle of each series, Megatron is empowered by some means and assumes the name Galvatron, but following the end of the one series where he is defeated or incapacitated, when he returns in the next series, he reverts back to his original name, only to rechristen himself Galvatron once again when he evolves the next time.
