The Autobots and Decepticons have been waging war with each for eons, and each different continuity brings further conflict for the two factions. With the various comics, tv shows, and movies centring around these wrestling robots, you have to wonder... doesn't anyone get a bit sick of it? Do some Autobots wonder what it would be like to not be the underdogs for once? Alternatively, surely some Decepticons must get tired of losing to the underdogs?
Sorry to remind people of Michael Bay's Trans formers movies, but thinking back to 2011's Dark of the Moon, during the obligatory ending speech, Autobot head honcho Optimus Prime said: "In any war, there are times where our allies turn against us." Well, wouldn't you know it, he was absolutely spot on.
Throughout the years of brutal brawls and bombastic battles, shocking deaths and eyebrow-raising resurrections, there have been more than a few turncoats in the Autobot ranks, and a good number of Decpticon traitors too. I suppose that after millions of years of having the same squabble against the same enemies, I'd be aching for a bit of change too.
