In the "Watchmen" sequel "Doomsday Clock," Lex Luthor mentioned to Lois Lane that someone has been undermining creation, like what Doctor Manhattan did with Wally West and the Justice Society of America. When Doctor Manhattan altered the Metaverse (and in turn the Multiverse) and created the New 52 Universe, Wally (prior to being freed in "DC Universe: Rebirth #1") briefly escaped the Speed Force to warn Doctor Manhattan that he knows what the latter did and that the heroes of the DC Universe will stop him. Wally was pulled back into the Speed Force afterwards.
