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 10,000. He then becomes Clockwork and kills Eon and his soldiers. Suddenly, Paradox appears and tells Ben 10,000 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 fight, but after defeating them, they disappear. In the future, Paradox tells Ben 10,000 that Eon is not dead and he is in the process of killing alternate versions of Ben. Realizing he is targeting his past self, Paradox and Ben 10,000 go to the past to meet the gang, after Gwen uses a spell to use the Hands of Armageddon to see through time. Soon, Paradox and Ben 10,000 appear.

Ben 10,000 reveals he is a different future duplicate than from the one Ben met when he was 10, and Paradox reveals many other worlds. Paradox informs them that the Hands of Armageddon is the source to their troubles, so Ben as Four Arms and Ben 10,000 strap the Hands of Armageddon in the Rust Bucket 3. However, it is activated and releases more soldiers. Ben fights with Goop and Ben 10,000 fights with Articguana, Spidermonkey, and Ultimate Humongousaur. When the ship was going down, Ben 10,000 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 10,000 uses 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 both Swampfires, and as he was about to destroy Ben, Ben 10,000 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 10,000'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 10,000 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.

 * When Ben 10,000 is battling Eon's Servants with XLR8 powers, he doesn't have the Ultimatrix symbol on his chest, however since he can summon the powers without changing, the Ultimatrix might be a part of him, thus him not having said symbol on his chest.

Trivia

 * This episode marks the second time an alien transformation has been destroyed (in this case it was 3 transformations). The first was Ghostfreak in Be Afraid of the Dark.
 * This is the second time that Paradox shows true panic, the first was in War of the Worlds Part 1. Coincidentally both these episodes feature Way Big being defeated, though in War of the Worlds Way Big is beaten by a machine, not an actual enemy.
 * Eon is a lot more powerful in this episode than in the Ben 10 Race Against Time movie, since he held his own against both teen and adult Ben, however in the movie he was easily beaten by 10 year old Ben. This is because of all the Ben 10s he absorbed so far, that and that he was a lot older in the movie than in this episode.
 * This episode was directed by Dwayne McDuffe (RIP)
 * This episode shows Way Big about the same size as Humungousaur in his giant form, however in War of the Worlds his foot alone would be able to squash all members of Ben's Team in one step.
 * This episode marks the second time Way Big fell over backwards, the first being War of the Worlds: Part 1.
 * This is the first time Ultimate Ben appeared, he was used by Ben 10,000 however.
 * This is the second time Way Big uses his cosmic ray attack, the first was in Absolute Power Part 1.
 * This is the second episode in which a live-action villain appears, the first being Revenge of the Swarm.
 * The title of this episode is a parody of the first episode of Alien Force.
 * This is Ben 10,000's first debut since the original series but in a different form.
 * This is the first time Paradox visited Ben 10,000 onscreen.
 * It was said to be that Ben, Gwen and Kevin don't hang out much as they used to because they each have their own driver's licenses.
 * It is shown that Ben 10,000 still says their names and he gets their abilities and can still turn into them, because he already figured out the Master Control.
 * A new alien, Clockwork, appears, but is only used by Ben 10,000
 * This is Eon's first reappearance and first cartoon appearance since the live action movie Ben 10: Race Against Time.
 * Ben 10,000 seems to be as immature and overconfident as his present self because he calls himself "even more awesome."
 * Paradox mentioned three alternate realities, each with their own Ben Tennyson:
 * A world where Gwen found the Omnitrix
 * A world where Albedo is trapped motionless in Alien X for a year
 * A world where Ben didn't have to destroy the Omnitrix to defeat Vilgax.
 * The cross worlds that existed cannot and must not leak into another as mentioned by Paradox.
 * The Cross worlds existed and continued into' Ad infinitum' meaning to infinity in latin so they are infinite parallel worlds.
 * Way Big was defeated easily for the first time ever. However it should be noted that the enemy was a lot more powerful than he is.
 * Despite this episode's title, the Ben 10,000 shown is apparently not the same Ben 10,000 as the one seen in the original series.
 * With young Gwen's appearance in this episode, the original series forms of all four main characters (Ben, Gwen, Kevin, and Max) have been shown in Ultimate Alien.
 * It is shown that the future is not set in stone and it can be changed, considering that Ben meets the current version of Ben 10,000 and that Paradox said to let the children discover their own futures. He also mention in the episode Paradox that time is like a river it flows and bends.
 * It appears either Ben or Gwen told Kevin of their trip into the future, as he knows about Ben 10,000.
 * This episode shows the last confrontation between Eon and Paradox, considering they were "old enemies" and Paradox had thwarted Eon's plans of getting to Ben multiple times.
 * This is the first time we see the past, present, and future versions of Ben in one episode.
 * Ben and Gwen have no memories of defeating Eon due to said battle having occured in an alternate timeline, as explained by Professor Paradox. This fills a large plot hole from the original series.
 * This is the first time Ben 10,000 appears and Spitter and Buzzshock are not used.
 * This is the first time since The Forge of Creation that Professor Paradox made a "breaking the fourth wall" statement, where he mentioned about "spoilers."
 * This could also be a reference to the series Doctor Who and the character Dr. River Song, who is a Time Traveller, and often stops people from finding out information about the future by using her catchphrase "Spoilers."
 * This is the first time since Alien Force that Way Big appears without Nanomech,
 * This episode shows Gwen uses her mana in a different way like the whip to defeat Eon's servants and the sphere-like mana that causes enemies to bounce off.
 * Ben 10,000 told both Ben and Gwen a little about their futures but he didn't mention Kevin's future.
 * This episode bears some resemblance to a movie by Jet Li, called "The One" in which the antagonist traverses alternate worlds, killing versions of himself and absorbing their energies for the sole benefit of being the one and only version of himself in existence.
 * This is the first time an Ultimate Form is used twice.
