During the Great War, Straxus ruled a colony world that he had dubbed "Darkmount", where he used his might to get the mechanoids and organics alike to serve his bidding. As a result he'd managed to perform several experimens, but on civilians, and on himself and his own soldiers.
Eventually, Hot Rod managed to destroy the palace on Darkmount, causing Straxus to flee back to the dying Cybertron.
It's unknown what Nova Prime offered Straxus to get the disposed tyrant to help him out during in his attempts to take cybertron, perhaps it was simply the thrill of experimenting on the core. Regardless, now Straxus is one of two emperors ruling over the Jupiter Empire.
When appearing to his public, the cybertronian scientist projects a holomatter avatar resembling a plague doctor.
