The story of Megatron from Transformers: Prime.

Early years

Megatronus (named after the Prime of the same name) was a gladiator in the pits of Kaon who disagreed with the corrupt system and vowed to bring down the system and bring equality for all, thus becoming political. In his mission he met the young Orion Pax, who assisted him in his mission and the young Orion came to see Megatronus as a mentor of such. Megatronus also gained a large political following including Soundwave. Megatronus decided to shorten his name to "Megatron" before seeing the high council. However once there Megatron revealed his true colors and demanded the old way be thrown over by force and demanded to be named the next Prime. However, Orion did not agree with Megatron's proposal and proclaimed a much more peaceful way of life which threw Megatron into the dark.

Great War Begins

Enraged, Megatron severed all ties with Orion and went on to create the Decepticon army with his followers, which took the remaining population by suprise who in response named themselves the Autobots. In addition to Soundwave, Megatron would gain many followers such as the treacherous Starscream, the logic-ruled Shockwave and the Vehicon army.

Transformers: War for Cybertron

Corruption of Cybertron

When the war for Cybertron was in its peak, Megatron led the the Decepticons. Determined to corrupt the core of Cybertron with Dark Energon to establish absolute control over the mechanical planet, Megatron allied with a formerly neutral Starscream and his forces and seized a full scale assault upon the Autobot's capital city, Iacon. Megatron did so to find the Autobot's leader, Zeta Prime, rip the key to Cybertron from his hands, and use it to unlock the core. After shredding through the city with the help of Starscream's air-support, Megatron beat Zeta, had his arrested, and thrown into Kaon's prison before taking the key for his own. However, Megatron soon realized that the "key" wasn't the actual key. It activated the true key, which was no object. In fact, it was a living, battleship sized Autobot named Omega Supreme. Having Omega hot on their tails, Megatron, Soundwave, and Breakdown traversed the lands of the core to finally beat the beast and forced him to unlock the very thing he guarded. Megatron's goals were a successful, deviously laughing as all of Cybertron was infected with Dark Energon by his own hands.


Though Megatron ruled Cybertron with an iron fist, the Autobots were relentless to surrender. Now led by the bold officer, Optimus, Megatron had his new nemesis arrested only for him to break out, free the already imprisoned Autobots, and save Zeta. Zeta unfortunately died of his torture woulds and Optimus, now a Prime, was labelled the last hope for the Autobots. Prime even beat the Decepticon's ultimate weapon, Trypticon, sparking a fresh bitter rivalry between Optimus and Megatron.

Rise of the Dark Spark

In Rise of the Dark Spark, Megatron is first seen monologuing alongside Optimus Prime, on the current conditions on the Great War for Cybertron. He notes that the Autobots are nearly defeated, and that it is the Decepticon's finest hour. He then gives a small narraration on the Dark Spark, and how it's the opposite of the Matrix. His second appearance is one over Shockwave's communications channel, where he tells the former to obtain the Dark Spark, before reprimanding Starscream over his questioning. After this small banter, he basically remains dark in terms of presence, until the mission "Ascension".

During this mission, he essentially tampers with the Dark Spark's powers, showing that it also possesses powers much like Dark Energon . He eventually challenges Optimus to a fight, using his newly obtained might to raise Cybertronian footsoldiers to fight Prime. This leads to Prime having to destroy 4 pillars, which restore Megatron's power, and once they're destroyed, they use the Matrix of Leadership and Dark Spark against the other respectively.

The Matrix is shown to be the prevaling force, and it creates a massive explosion in the confined quarters, causing both parties to be launched backwards, incapacitated. Megatron is too weak to move, and thus, is dragged off by a surprisingly worried Shockwave, whilst Prime stands up, pushes his chest panelling back in place, and looks up, only to realize the Dark Spark has been launched into space. The distressed Autobot Leader laments on how he feels "its presence will be felt elsewhere".


Megatron in Fall of Cybertron.

Transformers: Fall of Cybertron


After Optimus was informed by the spirit of Cybertron's core that it was far too damaged and corrupted to sustain life, he had to call the Autobots into retreat, herding them onto an "over-sized cargo hauler" called the Ark. However, Megatron refused to let the beaten bots flee and instead activated several anti-aircraft canons to make sure the Ark doesn't leave Cybertron's surface. The cannons were destroyed by the city-sized Autobot Metroplex who also squashed and murdered Megatron under his vast palm after the Decepticon captured Optimus. Megatron, who was just a dead hunk of scrap metal, finally had his position replaced by an disloyal Starscream. Soundwave was displeased with the death of his master and secretly constructed him a new body before reactivating his fallen commander and bringing him back to life. Megatron then barged out of Soundwave's workshop, ripped Starscream from the throne of the Decepticons, and re-established his leadership amongst the corps. Megatron later had Trypticon, who was a failure in a state of catatonia, rebuilt into the Nemesis, which followed the Autobots' Ark up into space.

Final conflict

The two ships were headed towards a mysterious black hole, and as they waited to soar into it they had a final brutal conflict. Optimus and Megatron met up on top of the Ark where they had a violent sword fight. The struggle led to the "death" (or major injuring) of Bumblebee, who attempted to intervene. The two robotic commanders continued their vicious conflict until they, the Nemesis, and the Ark were all sucked into the black hole, shot into an enigmatic section of the universe...

Iacon Relics

Following his successful attempt to get Orion Pax on the side of the Decepticons, Megatron was able to get in contact with the rest of the Decepticons and tell them of his presence aboard the ship. He told them that he was to be shown every courtesy and said that the first to address him as Optimus Prime would have their voice-box torn out. After his second-in-command Airachnid questioned if it was wise to have a former Autobot have free access, Megatron told her that nothing happened aboard the ship without his knowledge before telling her that she would do well to remember that. He told her that there still was no need for concern and stated that Orion did not possess the same fight Optimus Prime was so renowned for.

After Airachnid questioned what use he was to their cause, Megatron told her to rest assured before concluding that Orion Pax would indeed earn his place. As part of his ploy to trick Orion, Megatron told him that Ratchet was the leader of the Autobots. After Orion related that he could not conceive that Ratchet would be responsible for such horrors, Megatron told him that the "Doctor of Doom's" quest for power continued. As another part of his lie, he told Orion that "Ratchet's" marauders pursued the Decepticons to Earth's orbit before saying that the Decepticons felt the indigenous species was not ready to behold them. In what can be seen as plagiarism, he told the new Decepticon that the Decepticons had sworn to protect Earth, something Optimus and the other Autobots made their intention. After Optimus questioned why the Decepticons were called what they were, Megatron continued to lie, telling him that it was another Autobot scare tactic.

He related to his comrade that the name was meant to demonize the Decepticons and that instead, the group saw fit to wear it as a badge of honor as he recalled that if speaking the truth was deception, then they were gladly guilty. Megatron stopped the conversation, telling him that there would be plenty of time for catching up and that for the time being, he would need to rest. When talking to Knock Out, the Decepticon medic asked if they should beef-up the security around the Nemesis. However, Megatron told him that he believed that their new Decepticon would perform best if he did not feel threatened or confined in any way. He revealed to Knock Out that he had placed Orion's room of operations near the energon vault, which was always under constant surveillance. When returning to Orion Pax, he began to realize that his former ally and now fellow Decepticon asked many questions, even having to tell him that Starscream was dead.

When talking to Soundwave, he related his opinions on Orion and told him that it was a matter of time before he unraveled their fabrications. He only hoped that Orion was able to complete Project Iacon before he was forced to destroy him, once and for all. Things took a turn for the worse for Megatron when Autobot Arcee was able to get aboard the Nemesis. When the Vehicons were easily defeated by her, Megatron watched and remarked in surprise to their failure. After Airachnid asked Megatron to allow her to fight Arcee, Megatron objected, telling her that if Orion saw an Autobot or their destruction then everything he believed would be called into question. Megatron then ordered Soundwave to "escort" Arcee off the ship.

Confronting Orion

Following Arcee being teleported by Soundwave off of the Nemesis, Megatron confronted Orion about the incident. He apologized for the recent commotion and asked him if he was harmed in any way. Orion confirmed that he was fine and asked Megatron why he had told him that Starscream was dead before the Decepticon leader told him that he was dead to their cause. He told Optimus that Starscream was his most trusted lieutenant until he turned traitor and joined the Autobots. He continued by stating that never had he witnessed a more profound act of deceit before asking Orion if Starscream had done or said anything troubling to him. After Orion told him that he had not, Megatron said good and told him that perhaps it be best for him to forget about the incident and return to his project. Megatron soon left Orion alone and began to talk to Soundwave.

He told his longtime ally that he made a mistake not terminating Starscream a long time ago, calling it a mistake he did not intend to make again.

Dreadwing's Arrival

Decepticon Dreadwing arrived on Earth, joining up with Megatron and the other Decepticons aboard the Nemesis. He welcomed the Decepticon to his ranks, stating that he was as loyal as his twin Skyquake. However, Dreadwing had arrived seeking vengeance on the one responsible for his twin's death. Following Soundwave's playing of a clip of Skyquake's demise, Megatron related that Skyquake had died under the command of Starscream and not his own. After Dreadwing related that every Autobot on Earth would die for his twin's death, Megatron reminded him that Autobots were only dealt with when he commanded.

After Dreadwing went after the Autobots regardless, he contacted Megatron, who reminded him that he had ordered him not to do so. After Dreadwing told him of his current attempt to kill Optimus, Megatron related to him that Optimus was not so easily vanquished, a fact that he had been trying to get his fellow Decepticons to realize each time one tried to kill him. Regardless, Megatron allowed Dreadwing to have his vengeance, only in the memory of his departed twin and told Soundwave that he would be surprised if they ever hear from Dreadwing again.

He soon began to grow tired of Airachnid, especially after requesting to be reminded of her loyalty by Soundwave, who played a clip of her telling the Decepticons to consider a future without Megatron. He proceeded to order Dreadwing to kill her on his upcoming mission, telling him to avoid fighting her in corners. Ultimately, Dreadwing failed and his other loyal Decepticon Breakdown was killed instead by Airachnid.

Megatron angrily scolded Dreadwing for not going after his deceased comrade's remains. The Decepticons were soon contacted by Airachnid, whose signal was being tracked by Soundwave, and challenged Megatron to come and defeat her. Though Dreadwing asked if he could accompany him, Megatron angrily deemed that he had his chance and failed before taking off to fight Airachnid. Megatron came to Airachnid's location and was soon attacked by that of her Insecticon, whom profoundly pushed him and began to fight him. While Megatron battled the beast, he told Airachnid that she and her Insecticon would do best to remember his own previous training in the pits of Kaon. Despite being able to defeat and kill the Insecticon, the Decepticon leader had a large amount of stress placed on his body, causing him to fall to the ground after the Autobots came down to him. He asked Optimus if he planned to take him prisoner, only for the Autobot leader to point his blaster right in his face.

However, Megatron's luck managed to come into effect when Dreadwing, disobeying his orders, arrived with the other Decepticons. Though Optimus planned to kill Megatron there and now, he gave in after Dreadwing stated that the Decepticons would not attack him in return if he spared him. However, as Megatron left, he pulled the unthinkable by going back on Dreadwing's word and ordering the Vehicons to attack the Autobots while he and Dreadwing made an escape. While flying, he promoted Dreadwing to the position of his new first lieutenant.

Wheeljack's Involvement

With the Decepticons returning from their quests to retrieve the relics, Megatron questioned how only Soundwave was able to bring him back anything other than an excuse. Hardshell stepped to him and admitted to having killed Bulkhead in retaliation of Tox-En's destruction at the wrecker's hands, something that made Megatron deem that perhaps their endeavors had not been wasted after all. After stopping Hardshell and Knock Out from engaging in battle, Megatron asked Hardshell if he was certain that the one called Bulkhead was exterminated, being assured by him that the Insecticon had succeeded in terminating the Autobot by his very own hand.

As Knock Out complained over his paint job being ruined by the Insecticons, Megatron told him to spare him the dramatics and told him that it was merely a scratch. While Knock Out continued to bicker with Hardshell, Megatron was called away by a Vehicon, alerting him of a call that was coming from one of their mines. He asked him what seemed to be the problem after being alerted and discovered from the Vehicon that the caller would only speak to him. Recognizing the caller as Wheeljack, he told the Autobot that the loss of one mine would hardly be a blow to the Decepticon cause after the Autobot told him that he was sitting on one. Wheeljack told him that he was going to continue his attacks on the mines until he was given what he wanted, causing Megatron to ask what it might be before he discovered from the Autobot that Bulkhead had only nearly been killed and questioned Hardshell immediately. While Hardshell proclaimed his innocence and told his leader that the Wrecker was lying, Megatron ordered that if he had not killed Bulkhead, he best kill Wheeljack after telling the Insecticon that he owed him a spark. However, Hardshell was killed and his body was brought back to the warship where an Insecticon informed Megatron it was a human girl named Miko, which made Megatron look deeply surprised.

Silas' Emergence

Megatron was shocked that Silas had integrated his body with Breakdown's remains, resulting in the birth of Cylas, which he called an abomination. Nevertheless, he allowed "Cylas" the opportunity to prove himself worthy of a place in the Decepticon ranks by supplying them with a Project Damocles satellite. Though the initial results were promising, he sent Cylas to terminate Raf when the boy's hacking threatened to derail their plans. When Cylas failed to do so and the satellite was stopped, Megatron called him back and handed the former MECH commander over to Knock Out for dissection and experimentation with the Decepticon medic's experimental synthetic energon previously salvaged from Ratchet's failed field tests.

Duel between Star Sabers

After sending a decoy for Autobots, he was horrified by the discovery of the Star Saber, which he realized would make Optimus more dangerous than ever if he succeeded in reclaiming the weapon. So he had his minions immediately secure the sword along with the boulder in which it was stuck. Unfortunately, the arrival of a new Autobot delayed them long enough that the other Autobots discovered the deception. Optimus quickly managed to get hold of the sword despite Megatron's best efforts, and as the Autobot leader unleashed its power, Megatron was forced to retreat in his ship, noting it was now the Decepticons' darkest hour.

He then schemed to create the original Star Saber's equal. As he required a body part of a deceased Prime to use the Forge of Solus Prime, Megatron took Dreadwing through the space bridge to Cybertron and broke into the tomb of a Prime. After having Knock Out graft the Prime's arm onto Megatron, he was finally able to use the Forge of Solus Prime to forge a Dark Star Saber with some of his Dark Energon. Once Soundwave decrypted a new set of coordinates, he got the opportunity to test it on Arcee and Smokescreen when the pair found the first Omega Key, whom he swept aside with ease. With newfound confidence, Megatron challenged Prime to a duel, and though his new sword cleaved right through the Star Saber, Megatron was unable to stop the Autobots from getting away with the Omega Key. He did take a liking to his new weapon and arm and vowed that even if Optimus has the Iacon relics, it wouldn't be enough to take on Megatron with his new sword.

The Omega Keys

Gloating of his destruction of the Star Saber, he allowed Knock Out the opportunity to retrieve the next relic. Upon his return with another Omega Key, Megatron was intrigued by the relic, believing it to be part of a larger piece, and put the doctor to work analyzing it. He was less impressed with Dreadwing who returned empty handed from his mission (which would be the second time), and asserted that they needed to locate the Autobot base to recover their relics. Then Soundwave decrypted the final part of the Iacon databse, revealing Smokescreen to be relevant to their search.

Fight for the keys on Cybertron

After they extracted the Omega Key from Smokescreen, Megatron had Knock Out perform a cortical psychic patch procedure on the Autobot to learn their purpose. After discovering that all four could be used to revitalize Cybertron, he left Knock Out to find out where the Autobot base was, Megatron went to place the Omega Key in storage. However Smokescreen escaped and snatched it out of his grasp and made off with the other key as well. Though Megatron and his men gave pursuit as the Autobot jumped off their ship, Smokescreen got away. The Decepticon leader told Dreadwing they would need to locate the Autobot base quickly to retrieve the other keys, only to find Starscream on the bridge, with all four of the Omega Keys as a peace offering.

Reconciling with Starscream

Intending to find what Starscream really planned, Megatron had himself plugged into the rogue Decepticon with a psychic patch. Despite most of Starscream's memories turning out to be incriminating, he was eventually convinced to allow Starscream to rejoin the Decepticon ranks.

Autobots' Darkest Hour

Megatron attempted to stress to Dreadwing that the Decepticons needed to be united. Unfortunately Dreadwing was more interested in slagging Starscream, and Megatron had to blow a hole through him, thus killing Dreadwing. Megatron vowed at Starscream to not make him regret which one of them he spared. Once the location of the Omega Lock was established, Megatron took the Keys to Cybertron to find it. He and his men were attacked by the Autobots, who got away with the Keys while Megatron was otherwise occupied with fighting Optimus with his fixed Star Saber. Megatron was shocked that Smokescreen brought the spark extractor which destroyed Megatron's men and left the warlord by himself as he destroyed the device with his sword. With some help from Starscream, Megatron got hold of the Autobots' human friends to use as a bargaining chip to secure the return of the Keys.

Once he had the Keys back, Megatron had the lock activated and revealed that he intended to use it on both Cybertron and Earth so he'd have two worlds to rule, starting with Earth. Shockingly, this news resulted in Optimus slicing Megatron's sword arm off before destroying the Omega Lock. Though the Autobots escaped, Megatron would have the last laugh, as he knew the location of their base and used the Omega Lock to create a fortress there before Optimus destroyed it. If he could not conquer Cybertron, he could at least conquer Earth. From the Nemesis, he and his men attacked and destroyed the Autobot base as their first act of aggression.

Megatron rules over Jasper/Shockwave returns

Megatron (Prime)

Megatron sitting on his throne in his fortress Darkmount on Earth.

As the Decepticons were unable to find any corpses in the rubble, Megatron ordered worldwide surveillance. He got the opportunity to test his new citadel's fusion cannons on some foolishly attacking humans, and contacted Agent Fowler, claiming to want to co-exist peacefully with humanity. With the continuing failure of Starscream to get any information out of the captive Wheeljack, Megatron sent Knock Out to Cybertron to search for the relics lost during the Omega Lock battle. He was pleased when Knock Out returned with the long lost Shockwave.

Megatron appointed Shockwave his first lieutenant in charge of science. With failures mounting, including an aborted attempt by Starscream to track down the Autobots by freeing Wheeljack with a tracking device attached, Megatron's anger grew, leading Shockwave to bring to Earth a Predacon he had cloned.

Beast Hunters

After viewing the Predacon, Megatron told Shockwave that it did his spark good to see him tampering with creation. Though he received advisement from Starscream to not approach the Predacon, Megatron ignored him and referred to the Predacon as primal magnificence. Shockwave had the Predacon examine spilled energon of Wheeljack, with Megatron then sending the beast off to find him by uttering "let the hunt begin." The Predacon returned, failing to defeat or capture Wheeljack.

Later on, Megatron ended up berating Starscream and asking why his forces were scattered for no logical reason. Soundwave then presented a hologram representation of the Harbinger to Megatron who then proceeded to scream at Starscream over leaving Decepticon technology fully operational and unsecured. He later went on to stop and defeat Ultra Magnus from destroying Darkmount's cannon energy supply before forcibly bringing him to the top of Darkmount to announce his intentions; to execute all their prisoners, and to fire Darkmount's fusion cannons at the nearest human metropolis. He was then stopped by the untimely return of his enemy, Optimus Prime who had returned with a new form and proceeded to pummel Megatron, going as far as to send Megatron flying into the throne on the fortress. A short time later, he tried to stop Prime from destroying Darkmount, however, Prime gained the upper hand and threw Megatron into Darkmount's power core. Utterly defeated and horribly weakened, Megatron was then led from the crumbling base to the Nemesis.

After the return of Optimus Prime and the destruction of Darkmount, Megatron's forces would continue to dominate in their search for Predacon bones in order to raise an army of beast warriors. His forces would suffer a major setback when Starscream and Knock Out attempted to create a super-soldier using Synthetic Energon, Dark Energon and the captive CYLAS as a guinea pig.

With the revelation of Predaking's ability to transform and his newfound intelligence,[10] Megatron realized that the Predacons were a potential threat and decided to terminate Project Predacon. Following Starscream's advice, he allowed the Autobots to discover Shockwave's laboratory and destroy all the Predacon clones. Predaking would later swear revenge on the Autobots, not knowing of Megatron's treachery. The destruction of the clones would also reveal a means to restore Cybertron and cyberform Earth as Synthetic Energon was shown to react with cybernucleic acid to form cybermatter.

Megatron's Last Stand

Megatron announcing the Decepticon's last stand

Megatron would then commit his forces to rebuilding the Omega Lock and complete the formula for Synthetic Energon. To achieve that goal, he had the Autobot Medic Ratchet captured and convinced him to further complete his work on the subject. [11].[12] Once the formula was completed, Megatron gave Ratchet to Predaking to eliminate him. However, he didn't count on Ratchet convincing the Predacon that the Decepticon leader was really responsible for the destruction of the clones. [13] This caused Predaking to go on a rampage to confront the Decepticon Leader, during their conflict, Predaking easily bested Megatron, sending him flying across a hallway after a brutal beating. Starscream however, distracted Predaking long enough for Megatron to blast the Predacon out an airlock. At that point, the Autobots attacked the Nemesis, leading up to the final battle with the Decepticons.

Final battle and death

Megatron's death

Megatron killed by Bumblebee with the Star Saber.

Megatron then engaged in battle with Optimus Prime, having the advantage of the Dark Star Saber, however Optimus's new body allowed the Autobot leader to overpower Megatron. Due to the actions of the humans taking over the bridge, his own saber being knocked from his grasp, the Wreckers destroying his remaining troops and Smokescreen bringing the Star Saber into the fray, Megatron found himself being pushed into a corner. He then fired his fusion cannon at Bumblebee as the scout tried to bring the Star Saber to Optimus Prime, which resulted in Bee dying and falling into the Omega Lock before disintegrating, causing the Autobot leader to go into a rage while nearly pummeling Megatron to death, Megatron however, was able to turn the tables again with the Dark Star Saber and send Prime over the edge of the Lock with only a grasp on the side. He was about to deliver the finishing blow, but was distracted when he heard a new voice from behind, the voice belonged to the resurrected Bumblebee; who had been restored by the cybermatter in the Omega Lock. In that instant, Bumblebee pierced Megatron's chest with the Star Saber, extinguishing his Spark and slowly killing him as the others looked on in dismay, shock with even Optimus expressing sadness. Megatron's lifeless body then fell to Earth, burning through the atmosphere along the way. With their leader finally dead, the remaining Decepticons retreated with Starscream and Shockwave forced to share the last remaining escape pod from their ship.

Revival and Banishment

Megatron is Alive!

Megatron revived and possessed by Unicron

Megatron's body ended up underwater in Earth's ocean. The Dark Energon within him made it unable for him to join the AllSpark. Megatron was awoken by Unicron, who himself was awoken by the echo of Primus reawakening. Unicron transferred his entire mind into Megatron's body and upgraded it into a striking resemblance to Galvatron and took off for Cybertron. Among the upgrades was a Super-Luminal Space Drive, which allowed Megatron to reach Cybertron in mere hours without the need for a Space Bridge or ship despite the great distance between the two planets. Unicron forcefully told Megatron he would not be a ruler as Unicron would just use his body to destroy Cybertron, much to Megatron's dismay and shock. Unicron then traveled to Darkmount in an attempt to assassinate Bumblebee, Arcee, Smokescreen and Bulkhead. The four first believed it to be Megatron only to be corrected that it was in fact Unicron in possession of Megatron's body. Despite being in possession of great power, Unicron failed to extinguish any of the Autobots and deemed it fit to find a greater instrument of destruction.

Megatron turns good!

Megatron telling Starscream that the Decepticons are no more.

Megatron later tricked Unicron into attacking the still alive Predaking in the hopes the beast would inflict enough damage on him to drive Unicron from his body. But this backfires as Unicron used his powers to easily crush the beast. Megatron's life signal proved to be Unicron's weakness as the Nemesis could track it. During the conflict between Prime and Unicron, it is shown that Unicron was brutally torturing Megatron within his body, promising him "eternal suffering". When Unicron's anti-spark was finally torn from his body, Megatron was freed from the Chaos Bringer and regained control of his body again, with his eyes returning to their natural red. Starscream then arrived and talked about how his new body would "take things to the next level." Megatron then berated Starscream and announced to all present that having been a victim of oppression he had lost taste for inflicting it and that the Decepticons are no more, despite Starscream trying to convince him otherwise. Megatron flew off to parts unknown, seemingly exiling himself for his past actions.

Before Optimus became one with Primus, he stated that even Megatron has the ability to change; even several other Decepticons (such as Shockwave, Knock Out, the Predacons and several Vehicons) agreed to put aside their differences with the Autobots to ensure Cybertron's survival.

Transformers: Robots in Disguise

While Megatron has made no physical appearances on the sequel series Robots in Disguise, In the first episode there was a statue of him and the returned Soundwave did make an effort to contact his former master in "Portals" and "Collateral Damage". This was thwarted by Bumblebee's team on Earth. While Soundwave's nuclear beacon generator would have resulted in massive damage and deaths, Bumblebee's team foiled him for reasons other than direct worries about Megatron.

It is revealed in the episode "Mini-Con Madness" that Megatron once abducted seven Mini-Cons- Aerobolt, Tricerashot, Sawtooth, Buzzstrike, Windstrike, Bashbreaker, and Lancelon -and modified them as part of a scheme to make himself more powerful than even a Prime. This was ultimately abandoned once he abandoned the Decepticons, though the Mini-Cons were eventually awakened by Starscream. Starscream then announced he went back to hating Megatron and decided to exact revenge on his former master. 

It is later revealed in the two-part series finale "Enemy of my Enemy" and "Freedom Fighters" that Soundwave's scheme was actually orchestrated by Cyclonus and a group of Decepticons under his command (Treadshock, Riotgear, Skyjack, and a reluctant Cyberwarp), who had been posing as the Autobot High Council and had been trying to bury Optimus' legacy, blacklisting practically every Autobot who stood by the Prime's side. Cyclonus wanted to bring back Megatron to restart the Decepticon Empire, yet was either unware or unconvinced of Megatron's change-of-spark. Even more so, Cyberwarp rejected the Decepticon order, turning on Cyclonus and the rest of the High Council while in their combined form Galvatronus while allowing Bumblebee's team as Ultra Bee to restore order to Cybertron.
