Compared to the intense war that had come before, life on Cybertron after Optimus Prime and Megatron vanished through the planet’s space bridge was surprisingly stable. For a time, Shockwave was able to scrounge enough energon to keep the metaphorical lights on in the city of Iacon; although those Decepticons left behind enjoyed a modicum of safety and security compared to the dead, fuel-starved wasteland beyond, this peace came at a high cost: anyone, friend or foe, could be dragged into Shockwave’s dreaded laboratory and thrown into the meat grinder of scientific progress. Eventually, however, a Quintesson invasion drove him and his most loyal followers underground—unintentionally following the example of Grimlock and the Dinobots, who had already established the city of “Last Spark” as a refuge for Autobots.
