This Ben Tennyson is a what if version of Ben Tennyson.
His appearance is the same as the main timeline Ben at age of 10, except he does not have the Omnitrix.
In the episode Gwen 10, 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.
- Gwen 10 (first appearance)
- Ben technically wore the Omnitrix at one point (as shown in the comic), but in the real time episode, he doesn't.
