Power Girl
The Power Girl of New Earth faces off against the Power Girl and Justice Society Infinity of the new Earth-2, due to the Earth-2 Power Girl's grief and rage over the loss of her cousin prompting her to believe that the 'other' Power Girl is an impostor with some role in Superman's absence. Power Girl returns to New Earth with the help of the Earth-2 Michael Holt, until the Justice Society Infinity follow her and take her back to Earth-2, where it is revealed that the recreation of the Multiverse created a new Earth-2 and duplicates of its heroes, including its own Power Girl. The Power Girl of New Earth then returns home with the JSA.
