How to Watch How to Download

The eighth episode of Ben 10: Omniverse's sixth season tackles one of the biggest lingering plot points of the entire franchise with an incredibly unique mixture of cosmic lore and high-stakes legal comedy. In Season 6, Episode 8, "Universe vs. Tennyson," Ben is forced to answer for a reality-shattering decision he made long ago, putting his freedom and the entire universe on trial.

The cosmic consequences catch up to Ben when he is suddenly abducted and brought before an intergalactic tribunal. The plaintiffs? The omnipotent, multi-faced Celestialsapiens (the same species as Alien X), who are furious at Ben for violating the ultimate cosmic law: modifying or tampering with reality itself.

“When you rewrite reality, you don't just change the world — you leave a paper trail across the cosmos that eventually catches up to you.”

Episode Summary

The plot centers around a direct callback to the Season 1 episode, "So Long, and Thanks for All the Smoothies," where the original universe was accidentally destroyed by the Annihilarrgh. To save everyone, Ben transformed into Alien X and recreated the entire universe from scratch. While humanity went on living without a clue, the Celestialsapiens took notice of the subtle imperfections and unauthorized alterations Ben introduced during the recreation (such as the new flavor profile of Mr. Smoothy).

Ben is put on trial in a massive cosmic courtroom overseen by a Celestialsapiens judge. Represented by his eccentric legal counsel, Chadzmuth, Ben has to defend his actions against a relentless prosecutor named Starbeard. Starbeard argues that Ben's recreation of the universe is an act of intergalactic vandalism that threatens the stability of all dimensions.

When the legal arguments stall, the trial transitions into a ancient cosmic tradition: Trial by Combat. To prove his innocence and protect his reality, Ben must tap into the true power of the Omnitrix and go toe-to-toe with a warrior Celestialsapiens in a jaw-dropping battle that bends space and time.
