Ben 10 Returns

Ben 10 Returns is the season premiere of Ben 10: Alien Universe. It walks through a version of the first episode of Ben 10: Alien Force that is founded mainly on the important things.

Overview
While doing some boxing on his own in a gym, Ben is stopped when an enraged alien enters the gym from nowhere. Ben runs off to the Rustbucket in search of his Grandpa, but instead finds the Omnitrix, the most powerful watch in the universe, capable of transforming the user into one of over a million different aliens. After putting on the watch again for the first time in five years, Ben is prepared now to go against the DNAliens as he befriends old enemy Kevin Levin and adds cousin Gwen Tennyson to reach a common goal: Defeat the DNAliens!

​Trivia

 * As opposed to the episode of Ben 10: Alien Force after which this is named (which aired almost 6 months prior), this version is much shorted and plays out much differently, mostly using completely different aliens and having the gang not even meet a Highbreed Commander.
 * Also opposing its namesake episode of Alien Force, this episode does not feature the robotic dragon or the Forever Knights as villains.
 * Swampfire uses some kind of plant that knocks Kevin out.
 * Magister Labrid does not appear at all.
