Declaring that he will go back to taking cities , Brainiac shrinks France in the middle of a confrontation , and escapes one last time . Once the Earth is returned to normal size thanks to the Justice League creating a duplicate crystal in the Fortress of Solitude , Brainiac returns to his massive battleship and declared that he had also taken Metropolis and Gotham City on his way there .
