How to Watch How to Download

The spectacular, reality-bending multiverse saga continues in Ben 10: Omniverse Season 6 Episode 2, "And Then There Were None" (Part 2). Serving as the direct conclusion to the explosive season opener, this episode delivers high-stakes temporal action as the fate of every living soul in existence drops completely into the hands of an unlikely savior.

Following the catastrophic detonation of Vilgax’s Chronosapien Time Bomb, every single timeline containing an Omnitrix user has been utterly erased. With Prime Ben and all his alternate heroic counterparts completely wiped out, the entire multiverse has dissolved into nothingness—except for one lone, powerless reality containing the watchless Ben Tennyson.

“When all the greatest heroes across a thousand timelines fade into dust, the universe relies on a kid who never had powers to rewrite history.”

Episode Summary

The episode opens in a chillingly empty void where Vilgax stands victorious, having successfully used the time bomb to erase every Ben Tennyson across the multiverse. However, he soon realizes he made a crucial error: because No-Watch Ben never wore an Omnitrix, his timeline was untouched by the weapon. Left behind in the void alongside the villainous Eon, No-Watch Ben must find a way to survive.

Just before Vilgax can eliminate this final loose end, the brilliant Professor Paradox manages to rescue No-Watch Ben, pulling him into the temporal stream. Paradox reveals that since No-Watch Ben is the last surviving variant, he holds the unique power to reverse the cosmic damage. But to do so, he must overcome his own self-doubt and step onto the ultimate battlefield without any training.

In a thrilling climax, No-Watch Ben is temporarily gifted the Prime Omnitrix, using the power of Clockwork to undo the temporal wave. As the good Bens—including Ben Prime, Ben 23, and Gwen 10—are restored to existence, they launch a massive counterattack against Vilgax's evil alliance. No-Watch Ben ultimately returns the watch, proving that true heroism comes from the soul, not the wrist.
