Ben Tennyson (Gwen 10)

This is a non-canon version of Ben Tennyson.

Gwen 10
In this episode Ben is shocked to realize that he is back to the first day of summer with no Omnitrix. He tries to get it at the campsite but Gwen beats him to it. Later in the episode he and Grandpa Max get onto Vilgax's Ship. This is the only episode Ben never has the Omnitrix besides the entire Ben 10: Ultimate Alien series.

Trivia

 * Ben technically wore the Omnitrix at one point (as shown in the comic), but the realtime episode, he doesn't.
