And There Were None is the fifty-first episode of Ben 10: Omniverse.
The episode starts with Ben walking down the street. Suddenly, he hears a woman screaming for help whose cat got stuck in a tree. Ben helps the cat and starts to think about what it is like to be a superhero. He then realizes that he is late for his soccer game and looks at his broken watch, revealing that this is an alternate universe; one where Ben never received the Omnitrix. At the game, Ben is the goalkeeper, but unlike in the main timeline, his team won because of a player who hit the goalpost in the last minute. Following the match, Ben gets robbed by Kevin Levin who takes his broken watch. He then meets his grandfather who came to pick him up with the Rust Bucket.
Max asked Ben why he is so gloomy, in which he replies that he is bored of the same old routine in the same old town and that he wants something exciting to happen. Max told Ben that he does not need to find it, rather it will find him. When they make it home, Ben is surprised to see his cousin on his living room couch. They have a short, awkward talk until J.T. calls Ben, asking him to come to Mr. Smoothy's.
Shortly after leaving, Ben realizes he's being followed and walks into a dark alley to throw his pursuer off. His pursuer reveals himself to be Bad Ben, who looks just like him only with black hair. While Ben is in disbelief, Bad Ben declares that Ben must be destroyed and transforms into Ghostfreak. He then starts to chase Ben. Bad Ben is soon joined by Albedo and Benzarro, who respectively attack him after Albedo transforms into Humungousaur and transforms into Ultimate Humungousaur while Benzarro transforms into Frankenstrike. Cornered, Ben is saved just in time by Ben Prime who then transforms into Spidermonkey in order to rope him away and promises to take him to someone who can help.
At Los Soledad, Professor Paradox makes his appearance in front of the two Bens, explaining to No Watch Ben the concept of the multiverse; an infinite number of Ben Tennysons exist through multiple versions of the universe, but someone has been kidnapping them. No Watch Ben is an anomaly, as he is the only Ben Tennyson who never even heard of the Omnitrix, and he is being targeted for an unknown reason. Ben Prime is certain that Eon is behind the kidnappings, but Paradox notes that Eon would never leave tracks behind, suggesting that Eon works for a higher power. Paradox departs, instructing Ben Prime to protect his defenseless counterpart.
No sooner than Paradox leaves, Eon shows up to attack No Watch Ben, forcing Ben Prime to transform into Wildmutt and defend him. Ordered to escape, No Watch Ben runs for his life but comes across Vilgax, who reveals himself to be the one working with Eon. Vilgax tells them that he and Eon have been kidnapping Ben Tennysons across the multiverse to corrupt them, giving Vilgax control of an army of Omnitrix-wielding warriors. Bad Ben, Albedo, Benzarro, Mad Ben, and Nega Ben all reveal themselves. Vilgax states that No Watch Ben, though lacking an Omnitrix of his own, is a wild card that must be eliminated.
Before the evil Bens can destroy the two Bens, Paradox shows up with reinforcements: Ben 10,000, Ben 23, and Gwen 10. The good and evil Bens go alien to fight it out, while Ben Prime tells No Watch Ben to escape and hide. No Watch Ben is constantly stopped by the evil Bens, but is saved every time by an ally until Eon chases him down. Ben Prime transforms into Astrodactyl and swoops in and takes No Watch Ben to safety. No Watch Ben laments his lack of an Omnitrix, however, Astrodactyl simply tells him that "it's just a gadget", and simply having the Omnitrix doesn't make him a hero.
On the top of a building, Vilgax watches the battle. Eon approaches him and asks why Vilgax isn't fighting. Vilgax retorts angrily that Eon is in no position to make demands and orders him to open the portal. Eon grudgingly complies, and Vilgax pulls out a bomb through the portal. Eon reminds Vilgax of their partnership and points out he wasn't informed about a bomb; Vilgax answers that the bomb is a Chronosapien Time Bomb, and begins activating it. Eon gleefully notes that Vilgax intends to erase No Watch Ben from existence with the bomb, but Vilgax corrects him. The bomb will not affect No Watch Ben or his timeline, instead it will erase every other Ben Tennyson from existence. Eon blanches, remembering that he himself is an alternate version of Ben. Vilgax calmly thanks Eon for his help and tells him that his assistance is no longer required. As the bomb activates, Eon tries to escape but is swallowed up by the blast. No Watch Ben notices the blast and turns to ask Paradox for advice; however, the Professor is gone. The blast spreads, wiping out the other Bens one by one, save for Ben Prime who regroups with No Watch Ben, heroically shielding him from the blast. As Ben Prime fades into non-existence, his Omnitrix falls onto No Watch Ben's wrist and connects. Ben Prime instructs No Watch Ben to "be the hero" as he fades away.
No Watch Ben is soon attacked by Vilgax who manages to conceal the Omnitrix on his wrist from Vilgax's sight. Vilgax gloats that this was the sole reason he hunted down No Watch Ben; to destroy all the wielders of the Omnitrix at once. Declaring that No Watch Ben is no threat to him, Vilgax attacks, but Paradox pulls No Watch Ben to safety via a portal. Vilgax taunts No Watch Ben, declaring that he is doomed to run away in fear of Vilgax for the rest of his life.
Paradox takes Ben to a pocket dimension outside of time and space, where he confirms Vilgax erased all Ben Tennysons from the multiverse, leaving No Watch Ben as the last remaining Ben Tennyson. No Watch Ben sadly looks down, but regains a determined look on his face, ready to face whatever comes next. Paradox cryptically informs No Watch Ben that they will have to return "to the beginning".
