Ep 3. Battle at Biggie Box

Ben 10 2016 season 2 episode 3, titled "Battle at Biggie Box," follows the adventures of ten-year-old Ben Tennyson, who discovers a mysterious wristwatch called the Omnitrix. The Omnitrix allows Ben to turn into numerous different alien forms, each with its own unique abilities. Together with his cousin Gwen and his grandfather Max, Ben fights off monstrous villains and saves the world from danger.

In this episode, Ben and his family stop at a Biggie Box store to stock up on snacks during a road trip. However, they quickly realize that something is amiss when the store's robotic security guards attack them. It turns out that the store has been taken over by the villainous alien known as Fistrick, who has disguised himself as the store's owner. Fistrick plans to use a special machine in the store to drain energy from nearby power plants and sell it for a profit.

Ben transforms into his alien form, Four Arms, and battles the security robots. Meanwhile, Gwen and Max try to get to the store's underground control center to shut down the energy-draining machine. They encounter Fistrick's henchmen, who try to stop them with high-tech weapons and gadgets. However, Gwen uses her own magic powers to neutralize their attacks and create a path to the control center.

As Ben fights off more robots, he discovers that Fistrick has also taken control of the Biggie Box product displays, which have been modified to shoot out dangerous products like exploding sodas and electrified candy bars. Ben transforms into other alien forms, like Heatblast and Diamondhead, to deal with the various types of attacks.

Eventually, Gwen and Max succeed in shutting down the energy machine and apprehending Fistrick and his henchmen. As they leave the store, they notice that the merchandise has reverted to its normal harmless state. The episode ends with Ben expressing relief that he has saved the day once again and looking forward to the next adventure.
