from the other time periods to help him defeat the Dexters. A battle royal ensues, with each Dexter fighting the Mandark of their respective time period. Twelve eventually stands up to his Mandark who he defeats before rallying the other Dexters to reach the Core's controls. The fight ends in a stalemate, both groups restraining each other from pressing the Core's main button; however, Dee Dee emerges from the time machine welded into the Dexters’ now-destroyed robot. With her sudden presence confusing the Dexters and distracting the Mandarks, no one able to stop her as she – driven by her habit of seeing what buttons do – presses it herself. With the positive flow of the Neurotomic Protocore restored, the world's intelligence returns to normal and causes Mandark's three time-displaced selves to be sent back to their own time periods, his head to burst open with only his brain intact, and his fortress to collapse. However, the Dexters, realizing in anger that Dee Dee was "the one who saved the future," create a group of five robots from the rubble to get revenge on her for inadvertently taking away their triumph. The kid Dexter commands them to "destroy the one who saved the future" before sending them back to the past, unwittingly setting the whole series of events in motion himself. The Dexters return to their original time periods. The kid Dexter returns shortly before he originally left, and sees himself fighting the robots he just built with his other selves. Realizing the time loop he has created (or rather that he has come back too far back to before he ever left), Dexter becomes confused when he attempts to wrap his head around it all but ultimately decides to ignore it and goes to eat a sandwich. When Dee Dee – who had already used the time machine to return home after saving the future – shows up, Dexter gathers up his food and walks away, still angry. Unaware of what she did, Dee Dee is left to shrug at the audience in a confused manner, as the movie draws to an end.
