User blog comment:Rafe Adler/Major Crossover/@comment-1330227-20160524024112

I'd kind of like to see a crossover with both Supergirl and Power Girl. Let Power Girl be an Earth 1 hero, maybe as part of the Justice Society. They fight side by side. Would require a lot of green screen, but it would be cool. That would explain Kara's whereabouts on Earth 1.
