The Unnaturals is the thirty-fifth episode of Ben 10.
The Tennysons go to Philadelphia to watch a baseball game involving their hometown team. The Cannons pitted against a rival team called the Squires. Ben isn't happy to discover that J.T. and Cash are on the Cannons, who explains that 4 members of the team have gotten sick and had to be replaced. Ben is given a wedgie and realizes that he could have made the team, by default.
During the game, XLR8 sabotages Cash and J.T. before acting in favor of the team. After the first inning, Gwen analyzes footage she took of the game and discovered XLR8. But after some further digging, she discovers that the Squires have no past before this season and that they all share names with a bunch of famous old-time players.
Meanwhile, Ben's enjoying a snack break when he discovers J.T. and Cash being kidnapped by the Squires. He follows them to a warehouse where robotic duplicates have been made of them. At this point, Gwen and Max mount a rescue and Diamondhead levels the warehouse and rescue Max, Gwen, J.T. and Cash. Gwen discovers that the Squires are a ruse to infiltrate the game and kidnap the president who's in attendance. They decide to sneak in Ben by switching him with Cash.
After Ben narrowly wins the game for the Cannons, the Squires transform into war machines and attempt to kidnap the president. Four Arms saves the president, and stops the robot from killing as Ben. After the fight, the president thanks Cash and J.T. (mistaking Cash for Ben due to the fact that Ben was wearing Cash's uniform when he saved the president) and XLR8 gets his revenge on the duo by hanging them on a sign. Meanwhile, Enoch and the Forever Knights enter the stadium and says that the Tennysons will pay with their lives for foiling his plans.
