What Season 4 of Ben 10: Omniverse

Ben Tennyson, now eleven years old and one year after the original series, accidentally discovers an alien underworld beneath Bellwood. There, old enemies eager for revenge, new creatures and even more dangerous beings await him. The season alternates between the younger Ben and the sixteen-year-old Ben, a few months after Ultimate Alien, until both timelines merge into a single story. His main weapon is the Omnitrix, a prototype watch that lets him transform into different aliens. The villains come from both his past and the present: the Forever Knights, Psyphon, Albedo, Khyber and OTTO, among others. Ben has Rook, Grandpa Max and Gwen to stand up to them.
