More intrigue with the Sunderland Corporation and Flashpoint company...
The villain is Mark Sunderland, a man who made billions through Ponzi schemes before getting busted by Lois Lane. Afterwards, he purchased mind-controlling airborne nanites from Flashpoint, a company that deals in illegal wonder-tech. He hoped to use the technology to wipe away his crimes, but it was experimental and there were side effects; now he has to wear that gas mask all the time.
After some ranting, he orders Magog to stop breathing.
Some more ranting later, and Sunderland goes one further and orders Magog to die. And Magog does... for a while.
Sunderland's been attacking Flashpoint as vengeance for selling him defective technology. Flashpoint's decided to strike back.
