Megatron (RID)

Megatron is the wicked and ruthless leader of the Decepticons, a malevolent army of Transformers from Cybertron. After chasing the One from Cybertron, Megatron crashed on Earth and awoke many years later to restart the war between he and Optimus Prime.

Megatron appears as the main antagonist of the 2007 live-action Transformers film, Transformers: Robots in Disguise and as a secondary villain in the 2009 sequel Transformers: Rise of Unicron and it's 2011 follow-up, Transformers: War For Two Worlds. Michael Clarke Duncan provided Megatron's voice in all three films.

Life on Cybertron
Megatron began life as a Cybertronian protoform and raised alongside Orion Pax.

To Earth
Sentinel Prime managed to take the One and escape Cybertron by flying his ship through a space bridge as it collapsed. This damaged the ship and Sentinel was forced to enter cryogenic sleep to save him self, while the One was locked away within the ship. Megatron eventually tracked down the ship and attacked it, managing to bust inside. The emergency system alerted Sentinel to the danger and awoke him; he then attacked Megatron, who was trying to unlock the One. The ship lost control and began to spiral down towards Earth, hurtling through it's atmosphere and burning up. Megatron took Sentinel's canon and shot him dead, but not before Sentinel warned Megatron that pursuing the One would lead to his doom. The ship then tore apart, seperating Megatron from the One, although they both crashed into the Arctic Circle. Megatron quickly froze due to the icy conditions, and both he and the One were found and claimed by a US expedition. The humans decided to build the Hoover Dam to hide Megatron and the One.

Awakening
Years later, the Decepticons finally detected the One on Earth and made their move, enticing the Autobots to follow them. An encounter between Bumblebee and one of the Decepticons led to Daniel Witwicky and his later girlfriend Carly Spencer becoming caught up in the conflict. When Seymour Simmons captured Daniel, Carly and Bumblebee, he took them to the Hoover Dam.

Shortly after their arrival, Starscream arrived and launched an assault on the Dam, damaging the cooling system and causing Megatron to thaw out. He quickly trashed the Dam interior and escaped outside, where he was reunited with his second in command. He expressed dissappointment with him when he learned that the Autobots had taken the One to Mission City.

Confrontation
Megatron pursued the Autobot convoy to Mission City to try and take the One. After killing several humans, Megatron was confronted by Optimus, stating "One shall stand, one shall fall." Megatron quickly attacked Optimus and their battle spread across the city.

Meanwhile, Daniel was handed the One with the mission of escorting it safely to the top of a building where he would hand it off to a military helicopter. Megatron gave chase, pursuing him through the tower and cornering him on the roof, destroying the helicopter as well. Optimus, although wounded from his fight with Megatron, also followed and tackled Megatron, causing them to fall over the edge, taking Daniel with them. Optimus managed to catch Daniel and take the brunt of the landing. Megatron, also injured, dived onto Optimus and pinned him down. Optimus told Daniel to end it; insert the One into his chest to destroy it, even though it will take his life. However, Daniel dropped the One in the fall. Megatron laughed, telling Optimus that he will first kill him, and then take Earth. However, he then contemplated letting Optimus live so that he can watch Megatron's conquest. Bumblebee took advantage of Megatron's hesitation and picked the One up, leapt onto the Decepticon's back, and plunged the One into his chest. The One fused with his spark and then exploded, blowing Megatron's chest apart. Optimus stood sadly over his fallen brother and picked a shattered piece of the One from his chest. Megatron's body was later dumped in the Laurentian Abyss.

The Rise of Unicron
With Megatron dead, the Decepticons lacked a true leader. Starscream took over command but was a weak imitator of the great Megatron. The Decepticon's prayers seemed to by answered by the arrival of Unicron, who quickly overthrew the floundering Starscream and began to plan the Decepticon's revenge. Soundwave listened in on a human conversation and learned that the humans held a piece of the One at a MECH base and sent Ravage to retrieve it. A group of Decepticons then dived into the Laurentian Abyss and plunged the shard into Megatron's chest, ressurecting him.

Megatron returned to the Decepticon flagship, Nemesis, and confronted Starscream, believing that he had left him for dead in Mission City. Unicron stepped in to prevent Megatron from killing Starscream as he remained useful to him and then informed Megatron that the Decepticons served him and him alone.

Revenge
Megatron dispatched Starscream to terrorize Daniel and his friend Carlos Lopez at college. Just as Starscream arrived, so did Bumblebee with Carly. Bumblebee saved Carlos and Carly as Optimus arrived and Daniel became seperated from his friends. Megatron and Soundwave then appeared to battle Optimus, which spilled over into a nearby forest. Optimus defeated Starscream, who quickly retreated, and then killed Soundwave. However, distracted by Daniel's wellbeing, he turned his back to Megatron, allowing the Decepticon to impale and then shoot him. Optimus fell to the ground, fatally wounded, as Megatron fled.

With the Autobots virtually disabled without a leader, Megatron launched a full scale assault on the planet. Unicron broadcast a message, offering to halt the attacks if the humans turned over Daniel and his friends.

Solar Harvest
Unicron and Megatron headed to Egypt, where Unicron's grand plan was revealed; he was going to use an ancient Cybertronian machine which harvested Energon from the sun to steal the Earth's sun, plunging the world into darkness forever. Using Devastator, Unicron unearthed the machine, buried atop a pyramid, but needed the Matrix to activate it. Daniel, however, had already used the Matrix to ressurect Optimus, who flew to the peak and killed Unicron, destroying the harvester in the process.

Megatron was send tumbling down the side of the pyramid, were he attacked Optimus. After a brutal fight, Optimus blasted part of Megatron's face off and ripped his arm off before launching him through a wall. At Megatron's beckoning, Starscream arrived and helped Megatron up. Megatron warned Optimus that their war wasn't over, but was glad to be back in command of the Decepticons. He and Starscream then departed.
