After the Tennysons are attacked by a villainous, dimension-hopping Omni-alien known only as Alien X, they meet a parallel universe version of Max, who opens the door to hosting multiple Bens and Gwens, forming an army to combat this threat. Based on the 2016 reboot.
When Ben meets a young Generator Rex on the run from a hostile Providence, he must work through a series of misunderstandings, and defeat the dark wizard Hex in order to save the world.
