Duped

Ben has to fight forever knights with Keven, Julie's tennis game, and see the Sumo Slammers. He uses Echo Echo to divide himself into three copies, and they transform back into human form, creating three of himself. However, they each have a part of Ben's personality: one is immature, one is sensitive, and one is logical. The Immature Ben stays to watch Julie's match, the sensitive Ben goes to fight forever knights with Keven, and the logical Ben goes to the Sumo Slammers movie. Immature Ben proceeds to embarrass Julie while sensitive Ben can't fight properly. When the Forever Knights get a weapon, sensitive Ben calls his other selves for help, only to quickly realize that none of them are good fighters alone. How can the Forever Knights get stopped?
