Megatron

''"I knew you couldn't do it! You had your chance to save Cybertron... and you blew it! Now you shall watch Earth die!" ''―Megatron taunts Shockdrop

Megatron was not always the viciously powerful and brutally direct leader of the Decepticons; he was once brothers-in-arms with Optimus Prime and originally a gladiator from the Pits of Kaon. According to his files, he was appointed to be Cybertron's Protector and Commander of its Defense Force. Deep down, Megatron resented his comrade, knowing he was a Prime and therefore the most valued Cybertronian at the time. This anger drove Megatron to turn against his brother and wage a brutal War across Cybertron with his ever-expanding army of Decepticons (Soundwave chief among them). Megatron tends to become so obsessed with the object of his desires that he can ignore "secondary" matters, glaring flaws in his plans. As Starscream had so learned, trying to talk Megatron out of blindly going for his goals is useless. He will risk his world, his troops, and even his own Spark to achieve his goals; these things do not matter to him.

Despite this fatal flaw, Megatron did not achieve his dreaded status through simple warmongering. He's a manipulative, cunning strategist who can plan multiple schemes spanning millennia, and while they may overlap, they all help him toward his one, true goal: the restoration of Cybertron. For all his evils, Megatron genuinely strives to save his home planet some day, and with it, the Cybertronian Race... even if it means he has to rule it with his iron fist and put his bloodlust to good use to do so.

While on Earth, Megatron's attention was soon drawn to the Dark Spark, a dark relic that arrived in the Robot Defenders timeline from the Generation One universe. Upon taking possession of it, the artifact became a symbol of Decepticon Leadership. Megatron also appeared to be allied with the powerful space sorceress Quintessa, as both desired to revive Cybertron.

Megatron currently has two themes. One for his main appearances and one for battle.
