Indefinite Crisis of the Universe
From Jenny Everywhere Wiki
“The Indefinite Crisis of the Universe event” was an event which involved Reality Z-25 31-H as well as other universes with superhero populations, such as Earth-K. It occurred “years” prior to 2015. Involved superheroes included Max Atom, who had yet to fall from grace, and the Crisis was witnessed by only very few non-powered “Earthlings”; those select few included Wilson, who would go on to become the mayor of Reality Z-25 31-H's New York City.
