Complete story — includes the ending

Ben's girlfriend Julie Yamamoto has a major tennis match, but Ben is torn between attending and aiding Kevin in stopping the Forever Knights from robbing a museum, while also wanting to watch a new Sumo Slammers movie. Ben eventually turns into Echo Echo and divides into three copies, then returns to his human form so that he can attend all three events at once. However, the split causes Ben's personality to be divided among the trio; while the arrogant Ben attends Julie's match, the kind Ben aids Kevin and the rational Ben watches the movie. Eventually, all three Bens reunite to help defeat the Forever Knights to prevent them from stealing ancient alien battle armor. Ben attempts to reconcile with Julie, but after revealing his actions, she is disgusted with him and storms off. Ultimatrix alien debuts: Rath, Echo Echo, Big Chill, Upchuck, Cannonbolt, Lodestar
