Mr. Murray was the CEO of Maxim Properties. He was an amoral bussiness man who had no scruples about making deals with tyrants and dictators who oppresed their countries, if he could make a profit. Even with tyrants from other worlds or universes. He also had no problem with backstabbing his associates or back up on a deal if he had the winning hand.
That is why he made a deal with Saturna, Simon Magus and Tazzala, proving them with weapons and earth technology from earth to suppress and attack on the conquest of Saturna if he could take the resources of the differents conquered realities.
However, he don’t counted with the intervention of the Creature Commandos, who caused the defeat of Saturna and making all his deals to fall apart.
