Dimension 4

Dimension 4, often called the Gwen 10 Timeline, is an alternate reality where it was Gwen instead of Ben who found the Omnitrix.

Gwen Tennyson
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 reality'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 10 apparently, unlike Ben Prime and Ben 23, doesn't name her Omnitrix's alien forms.

Ben Tennyson
Ben Tennyson in this timeline is identical to his prime counterpart when he was 10. However, the difference is that this version of Ben didn't find the Omnitrix, as he was asleep at the time the Omnitrix arrived.

Max Tennyson
Max Tennyson in this timeline is identical to his prime counterpart when he was 59.
