How to Watch How to Download

The tenth episode of Ben 10: Omniverse's sixth season blends globe-trotting archeological mystery, high-octane racing, and classic monster tracking. In Season 6, Episode 10, "The Secret of Dos Santos," Ben Tennyson, Rook Blonko, and Kai Green head deep into South America to uncover an ancient secret that has ties to both Earth's history and intergalactic technology.

The adventure kicks off when Kai Green enlists Ben and Rook's help to find a legendary, long-lost artifact hidden deep within a remote temple. However, the mission quickly turns dangerous as they discover they aren't the only ones hunting for the temple's treasures — the ruthless and persistent tracking specialist Suemund is close on their heels.

“Chasing ancient relics in booby-trapped temples is stressful enough, but it gets a whole lot worse when a giant alien cryptid decides to join the race.”

Episode Summary

The plot centers around the team navigating their way through the rugged wilderness to uncover a hidden temple connected to the enigmatic figure "Dos Santos." Kai's expertise in historical artifacts proves essential as they decipher ancient glyphs and bypass lethal, mechanism-driven traps designed to protect the temple's inner sanctum.

The stakes escalate dramatically when the group crosses paths with the **Chupacabra**, a fearsome alien creature that has spawned terrifying local legends on Earth. Rather than a simple myth, this beast turns out to be a highly aggressive alien entity that poses a major threat to both the Plumbers and the local environment.

As Suemund closes in to seize the artifact for his own dark purposes, Ben must constantly shift between agile and defensive alien forms like **Blitzwolfer** and **Armodrillo** to combat the local wildlife and Suemund's advanced gear. The team has to combine Kai's historical insights, Rook's tactical expertise, and Ben's raw power to solve the final puzzle before the entire structure collapses around them.
