The Green Goblin kidnapped Arina Grande and took her to the Batcave to play Mariokart then the sun exploded and everyone died (except superman and Captain Jack Harkness). When Superman came bake to earth (Jack decided he wanted to swim around in space) he found the Justice Leauge and then realized that they were really fat. He discovered that to sustain substantal health they ate the dead carcases of all of the dead humans (except Batman because, well, YOU JUST CANT KILL BATMAN AND EAT HIM!!! HES TO AWESOME!!!)
