In this timeline, during the stop at Yosemite National Park at the start of the summer vacation, Gwen found the Omnitrix instead of Ben. On the same night that she found the Omnitrix, Gwen 10 was recruited by Professor Paradox and No Watch Ben to join them in No Watch Timeline for a battle between the good and evil Omnitrix-wielders from across the multiverse. After Vilgax and the evil Bens were defeated and sent back to their respective realities, Paradox took Gwen 10 back to her timeline.
Gwen 10 looks identical to, and has the same sense of clothing as, the Prime Timeline's version of Gwen when she was ten, although Gwen 10's shirt has a number 10 in the cat logo. From what has been seen of Gwen 10's personality, it is identical to that of her Prime counterpart when she was 10.
Gwen does not name her Omnitrix's alien forms.[DJW 2]
In this timeline, Ben Tennyson is identical to his prime counterpart when he was 10. However, the biggest difference is that this version of Ben did not find the Omnitrix, as he was asleep at the time the Omnitrix arrived. He is essentially a tagalong that gets in Gwen's way.[DJW 3]
In this timeline, Max Tennyson is identical to his prime counterpart when he was 59.
- And Then There Was Ben (first appearance)
- The Gweniverse was mentioned by Paradox in Ben 10,000 Returns when he was explaining crosstime to Ben's Team.
