Ben 10,000 Returns

Ben 10,000 Returns is the 30th episode of Ben 10: Ultimate Alien, and its the tenth episode of the second season.

Plot
In the future, Eon is attacking Ben 10,000's headquarters, where he criticizes Eon's decision to attack him. He is then attacked by Eon's foot-soldiers, but Ben 10,000 fights Eon and his soldiers with a combination of Ultimate Humongousaur, Articguana, and Heatblast. As Eon was about to kill Ben 10k, Ben 10k becomes Clockwork and kills Eon and his soldiers. Suddenly, Paradox appears and tells Ben 10k that the fight with Eon is not over.

Back in the present, Ben, Gwen, and Kevin are investigating a disturbance. They find the Hands of Armageddon, and when Ben touches it, it releases some of Eon's soldiers. Ben transforms into Spidermonkey to fi  ght, but after defeating them, they disappear. In the future, Paradox tells Ben 10k that Eon is not dead and he is working on killing alternate versions of Ben. Realizing he is targeting his past self, Paradox and Ben 10k go to the past to meet the gang, after Gwen uses a spell to use the Hands of Armageddon to see through time. Ben is surprised to meet his future self.

Ben 10,000 reveals he is a different future duplicate then from the one Ben met when he was 10, and Paradox reveals many other worlds. After Ben as Four Arms and Ben 10,000 strap the Hands of Armageddon, it is activated and releases more soldiers. Ben fights with Goop and Ben 10k fights with Arcticguana, Spidermonkey, and Ultimate Humongousaur. When the ship was going down, Ben 10k becomes Jetray and is able to land the ship safely. Paradox appears again and tells them that the Hands of Armageddon must be destroyed. Ben becomes Way Big and Ben 10k becomes Clockwork while Gwen protects her, Kevin, and Paradox from the blasts. However, both of their Ultimatrix symbols glow purple and a portal is opened for Eon to emerge. When Ben tries to stop him, Eon fires a blast turning Ben into a disintegrating statue.

However, he just destroyed Way Big, forever eliminating him from the Ultimatrix. Ben is still safe, and transforms from Swampfire to Ultimate Swampfire to fight while Ben 10k uses XLR8. Eon destroys Swampfire, and as he was about to destroy Ben, Ben 10k protects him with Diamondhead. He then gets him away from Eon using XLR8 again, and Gwen uses another spell to stop time around them. They take off the helmets of Eon's soldiers, but finds them all to have Ben's face. Eon reveals that instead of destroying the Bens he defeats, he absorbs their individual powers and turns them into his slaves. Eon takes off his own helmet to reveal he has Ben 10k's face, and that he is the Eon from their watches, not the one from the Hands of Armageddon. Soon enough, Eon is destroyed when Ben destroys the Hands of Armageddon. All of the timelines Eon altered are restored properly, and Ben 10k helps Ben get Way Big and both Swampfires back along with unlocking all his old transformations and a few new aliens for Ben, just to annoy Azmuth. Before leaving, Paradox gives a warning about Old George and the Lucubra.
