Editing Megatron (section)

===Animated series===
Megatron was a regular character in the ''[[Transformers: Prime]]'' animated series, the main antagonist along with [[Unicron]], and one of the main characters in ''[[Transformers: War for Cybertron|War for Cybertron]]'' and ''[[Transformers: Fall of Cybertron|Fall of Cybertron]]''. He is the leader of the [[Decepticons]] during the Great War on Cybertron. During the [[Golden Age]] on Cybertron, Megatron named himself Megatronus, named after one of the Thirteen, Megatronus Prime. Megatronus was a gladiator in the pits of [[Kaon]], who grew ambitious and saw corruption within the caste system and sought to put an end to it, with his own rule. Megatron began talking with his old friend, [[Orion Pax]], who became a mentor to him. After leaving the [[Kaon|gladiatorial arena]] for the political one, Megatronus saw fit to shorten his name. When he was summoned up to the high council he asked to be named the next prime, but was turned down. Instead, Optimus was named the next prime. When "Megatron" was rejected by the Autobot High Council, and felt betrayal on Optimus' part, he waged war on Cybertron and left the planet wasted. Now he and his long story rival, [[Optimus Prime]], battle on the planet [[Earth]] for control of the [[human]] planet.

Megatron's first grand plan was to invade Earth with an army of undead [[Terrorcon]]s but he himself was gravely wounded, leaving [[Starscream]] in charge of the [[Decepticon]] army until he was reawakened by [[Bumblebee (Transformers)|Bumblebee]] who he managed to possess for a brief time by traveling into Bumblebee's mind using a cortical psychic patch. Later in the series Megatron, found himself teaming up with Team Prime, at that time, to counter the threat of [[Unicron]]. After Unicron's defeat, Megatron found himself both on a mission to retrieve the Iacon relic weapons as well as keep his troops in line from various infighting among the ranks which resulted in a few casualties and several betrayals. Megatron's plan was to restore Cybertron and cyberform Earth in order to rule both. Megatron was even able to build his fortress, Darkmount using the Iacon relic known as the Omega Keys/Lock. However, Optimus foiled his final plan, by destroying the Omega Lock base with the Star Saber, effectively killing two birds with one stone. Megatron, seeking revenge, used his army and his warship, the Nemesis, to destroy the autobot base and anyone who was in it. Shortly after the destruction of the base Megatron sent massive search parties to find the surviving Autobots and was even given a [[Predaking|Predacon]] to look for them. However, Darkmount was soon destroyed by an all-out attack by the Autobots. Megatron's next plan was to create an entire army of Predacons to serve him. However, when his lone beast evolved and transformed, Megatron became fearful of what he was capable of and scrapped it. In the destruction Megatron found the means to restore Cybertron once more with Synthetic Energon, as Megatron's plan to rebuild the Omega Lock progressed, the Autobots invaded the Nemesis. As Optimus and Megatron fought, the tyrant was finally killed by Bumblebee.

The series' finale movie, ''[[Transformers Prime Beast Hunters: Predacons Rising]]'', though "killed", Megatron was awakened by Unicron, who took possession of his body and reformatted him with new improvements upon his chassis. While in his body, Megatron's "spirit" is alongside that of Unicron's where he is dwindled in size by Unicron's being. Megatron originally believes that Unicron is there to help his conquest of intergalactic domination. However, throughout the film, Megatron soon realizes that his final goal to rule the universe alongside Unicron would soon be plunged into nothingness by Unicorn telling him that his only purpose was to be a vessel. Powerless, Megatron concurred a plan in order to force Unicron to leave his body by tricking him into believing the Predacon, Predaking, would be a loyal warrior on reuniting with his former master. After a quick battle, Megatron expresses his view point for freedom from the prison Unicron has put him in by expressing, "for regaining my freewill, even over a mangled and deficient frame, is preferable to enduring a waking life as your slave!" -.<ref>[https://www.scripts.com/script/transformers_prime_beast_hunters:_predacons_rising_22198/3 Megatron]</ref> For his defiance, Unicorn punishes Megatron by inflicting harm on his "spirit". Megatron is held powerless by Unicorn until the final battle between Unicorn and Optimus, where Optimus tricks Unicron by leaving the vessel containing the [[AllSpark]] empty, sucking Unicron's being out of Megaton's corpse. Megatron then regained control of his body, but by then he abandoned any plans of conquest, having realized the true meaning of oppression by Unicron's treatment of him. He abandons leading the Decepticons and disbands them as a military force, then flies off into space, presumably as banishment and self-imposed exile for his past actions. Optimus even stated that every sentient being, including Megatron, has the capacity to change for the better.

While Megatron doesn't appear in the sequel series, ''[[Transformers: Robots in Disguise (2015 TV series)|Transformers: Robots in Disguise]]'', or the spin-off, ''[[Transformers: Rescue Bots]]'', which is aimed at younger audiences, he is sometimes referenced or mentioned, tying those series into the larger continuity.
