He always seems to have a plan within a plan! How riveting is that!? Plan A: get the Allspark - take over Earth (In case Plan A fails) Plan B: find the Star Harverster - destroy The Sun (In case Plan B fails) Plan C: activate The Pillars - rebuild Cybertron (In case Plan C fails) Plan D: manipulate the humans - take over Earth... again I wonder what he's up to next, hmm.
I'm going to have to disagree because of the convoluted nature of how the films have to come up with crazy stuff to say oh well it was Megatron's plan all along to connect the movies. It would be like a Rocky movie if Rocky got a horrible beat down and the next film he went it was all part of an elaborate plan to get this other guy over confident. Also these plans seem about as brilliant as a Wile E. Coyote scheme, they are all just as doomed you just don't have product placement by Acme. As Livingdeaddan pointed out none of Megatron's plans ever work out.
Agreed! He is unpredictable and insidious - it's true! Although I think, many of his ideas he assimilated from the Fallen and develop them into a strategy. His main mistake - he underestimate the dedication of Autobots and humans' courage.
Maybe he lives by Edison's maxim of 'I have not failed. I've just found 10,000 ways that won't work.'
Megatron's plans do tend to work pretty well until Optimus pulls out something that happens to screw it all up. Movie One, fair enough he was just running around smashing things and then he got a super cube in his chest. Bam, he dead. In ROTF, when he gets things going, he and his boss were so close to blowing up the sun until it turned out Optimus had combined with a Blackbird to form a super Optimus capable of ripping off faces and force-feeding him his own gun. In DOTM, he did pretty good on setting up a planet-warp with his new friend until it turned out the Autobot hadn't exploded and snuck into his house to fuck him up. And in AOE, his elaborate deception is going well until Optimus summons gigantic fire-breathing monsters to eat his troopers. Really, Megatron's plans fail because just when he thinks he's got it, Optimus jumps into the fray and rips either him or his buddies to pieces. You have to admire him in that regard; he's the one Megatron saddled with an Optimus who won't hesitate to tear his spine out with an axe but he keeps on doing his wacky plans anyway.
Earth was not even in the equation going off of what was outlined in the first film. Megatron went after the AllSpark purely so he could go conquer Cybertron. The point about him raising a midget robot army from human tech (reverse engineered from Megatron) was first brought up by Ratchet, without any real evidence supporting that claim as they couldn't even be sure the guy was alive at that point - only the Decepticons had the S7 "Iceman" files to imply that much. Actually, snuffing out the sun was a byproduct of what actually was pretty heavily implied to be Megatron's actual motivation - the Sun Harvester ate stars to produce Energon, which with the destruction of the AllSpark left that as the only means of feeding the bunch of larval protoforms on Saturn or wherever. Er, Plan C actually makes it such that had Plan B worked, Cybertron would be a lifeless husk as no sun means all of humanity would die. The entire motivation for Sentinel and Megatron working together was that they were so goddamn lazy and egotistical that they would rather do some roundabout mass-enslavement plan of a smaller, physically weaker species they would force to rebuild their planet...instead of realizing it would be easier just to stop being dumbasses about the whole thing and rebuild their planet by themselves. So, had Plan B worked, there'd be a lot of Energon....but nobody to rebuild Cybertron and no sun to relocate Cyberetron to at the same time (because that also was kind of the reason they were bringing Cybertron into Earth's relative location in space - they needed the Sun as well for some reason) That relied entirely on humans being literally so stupid as to reuse any parts from the individual who tried causing a human holocaust three times within a decade - as in regressively stupid because back in the first movie, the army straight up dumped all the dead cons into the ocean to destroy their remains (didn't work in the end but that's besides the point). That was not a plan, that was dumb luck on his part.
