The only being on DC Earth that Neron did not care to fight/ beat the crap out of, was the Spectre. Instead, he made a deal with The Spectre Force and ripped Corrigan's out of the Spectre Force and put in a guy with no willpower that couldn't control the Wrath. So the Wrath could do it's thing with no hinderance from a powerful willed mortal anchor. The deal was that if he did this for the Spectre, that Spectre wouldn't come after him.
