Unicron Unicron is an ancient and extremely powerful transformer of unknown origin. He was one who created the Minicons. They were to serve in fueling the war between Autobots and Deceptions, but the Minicons refused to follow their creator's orders and left for Earth. During that time, Unicron posed as a Cybertronian Moon, using his acolyte Sideways to set the pieces in place. Once all goes according to plan, with the three most powerful Minicon Triads in his heart chamber, Unicron transformed into robot mode and attacked Cybertron, decimating the Decepticon and Autobot forces. With the Minicons trying to hold him off, Optimus and Megatron, enter Unicron's body (with the kids and their Minicons following them) to stop Unicron from the inside. But it was kids' words that free the Triads, which forced the weaken Unicron to retreat before he lost power completely.
