Election day is here...and Grimlock wants your vote! Now this ain't no General Election we're talking about here, it's something far more important...like who's going to replace Optimus Prime as Autobot leader! That's right - now the Autobots have finally accepted that Optimus Prime is gone and his body committed to the stars - they must find someone to replace him. But who could possibly fill the shoes of the bravest, strongest, wisest, most compassionate and generous Autobot of all? Grimlock - the Dinobot commander - thinks he's the man for the job, but the other Autobots might take a bit of convincing. How far will Grimlock go to get what he wants? the answer to that may spell the end of the Autobots, especially in the light of the latest Decepticon to arrive on Earth. Get ready to meet the biggest, meanest and nastiest Decepticon of all - TRYPTICON!
