Gwen freezes all the Eon's minions and removes their masks, and they are revealed as Bens. Eon says that he has absorbed all the alternate timeline Bens to be his slaves and these both are the last ones. He removes his own mask and shows that he himself has absorbed a Ben 10,000 and thus has the face of Ben 10,000. Then while Ben 10,000 fights Eon, Young Ben destroys the seal. Eon bursts and later Paradox confirms that he is dead. Paradox even confirms that the alternate Bens will get back to normal soon. Paradox says that young Ben has lost Waybig,Swampfire,and Ultimate Swampfire. Ben 10,000 gives back Waybig,Swampfire,and Ultimate Swampfire as well as all the aliens Ben ever become and some new aliens too.
