Suddenly, there was an explosion! Through clouds of smoke, Megatron spied VORTEX, Decepticon interrogator. With him was KNOCK OUT, Decepticon mechanic. These two Decepticons would not have enough power to break him out...then Megatron spied DEVASTATOR, one of a series of three identical powerful and monstrous Decepticons. Vortex explained that he had convinced Devastator to save Megatron, and that they had brought him a prize. Knock Out gave Megatron a piece of DARK ENERGON, which upgraded him to a new KREON body with a sword hand.
They checked over as much of Space Jail as they could, but record found by BARRICADE, Decepticon scout/warrior, showed the other Decepticons had been smelted down for scrap.
Megatron vowed revenge! He destroyed Space Jail, and headed back to Earth.
Using techniques developed by Shockwave, Megatron developed robotic warrior bodies for himself, Knock Out, and Vortex. Devastator's KREON essence was too powerful for one body, so Knock Out developed a way to split Devastator into four component parts for his robotic bodies. These bodies later figured out how to combine into one mighty warrior.
Megatron learned that the ultimate Decepticon weapon had been brought to Earth thousands of years before, but was split into component parts. He sent his warriors on a quest for the parts, hoping to run into Optimus Prime again...
