Ben 10 Omniverse Season 2 Episode 9 — "Store 23"

How to Watch How to Download

The concept of the multiverse cracks wide open in Ben 10: Omniverse with Season 2 Episode 9, "Store 23." This landmark, highly influential installment introduces one of the most iconic concepts in the entire franchise—the existence of alternate versions of Ben Tennyson living vastly different lives across reality.

While chasing a mysterious cosmic disruption, Ben and Rook find themselves accidentally pulled through a cross-dimensional rift. They land in a neon-soaked alternate reality where Ben Tennyson never had a Grandpa Max to teach him humility, turning the young hero into an arrogant, ultra-wealthy superstar who corporate-markets his alien transformations like products.

“When you face a version of yourself who values fame over family, being a hero requires teaching a lesson in true responsibility.”

Episode Summary

The cosmic detour begins when Ben and Rook investigate a massive energy anomaly in Undertown, only to be dragged across space-time by a dimensional tear. They arrive in a parallel universe that looks vastly different, centered entirely around a massive commercial empire anchored by a 13-year-old hero named Ben 23. Lacking the guidance of a grandfather figure, this version uses his watch—the Hero Watch—strictly for corporate sponsorships, media stunts, and wealth accumulation.

Ben 23 treats his alien forms like pop-culture brand items, giving them flashy, commercialized names. When a group of regular citizens struggles against structural threats, Ben 23 is more focused on camera angles and merchandise sales than actually protecting people. Our prime Ben Tennyson is deeply disturbed by his counterpart's vanity and attempts to intervene, leading to an inevitable clash of heroic philosophies and custom alien duels.

As the two versions square off, they are suddenly ambushed by a multidimensional threat in the form of a rogue Tetramand warlord. To survive the crossfire, prime Ben shifts into strategic forms like Bloxx and Feedback, forcing Ben 23 to watch real, selfless heroism in action. Through this intense battle, prime Ben takes on a mentor role, showing the young pop star that the true power of the watch isn't about making a profit, but about protecting those who cannot protect themselves.

Fun Facts & Trivia

Did You Know?

This episode officially introduces the fan-favorite alternate universe hero Ben 23, who instantly became a massive recurring character throughout the rest of the Omniverse saga.
Ben 23 uses completely different commercialized names for his aliens: Rollaway (Cannonbolt), Electricyeti (Shocksquatch), Charcoal Man (Heatblast), and Eye Guy is hilariously named "See-More."
Because of the specific dimensional rules of this universe, all of Ben 23's alien transformations feature striking blue eyes and a blue Omnitrix symbol instead of the classic prime green.
The title "Store 23" is a playful corporate pun, directly referencing the massive consumer-driven store chain and marketing empire that Ben 23 built around his alien celebrity status.
Tara Strong returns to voice the 13-year-old Ben 23, perfectly capturing an arrogant, hyperactive child star persona that directly contrasts with her classic portrayals of young prime Ben.

Legacy & Impact

"Store 23" is universally praised by the fandom as one of the most brilliant and vital world-building episodes of the entire Ben 10: Omniverse series. By breaking the barriers of reality, the writers paved the way for massive, high-concept multiversal arcs, time wars, and ultimate team-ups that would completely define the structural grand finale of the show.

The episode's distinct creative choices, sharp humor, and deep respect for the franchise's foundational morals made it an instant classic. It remains a powerful reminder of why the original series resonated so deeply—proving that without heart, maturity, and a supportive family, even the most powerful device in the universe is just a fancy watch.
