Gwen 10
First Appearance Ten Over Ten Thousand

Gwen Tennyson is a hero in Earth-1010. She first appeared in Ten Over Ten Thousand. She is a human from the planet Earth. She exists in the Delta Dimension.


Gwen Delta appears similar to her Prime counterpart when she was 10, albeit with different clothes and an altered hairdo. She is identical to the canon Gwen.


Gwen is generally friendly and tomboyish. She often tries to help Ben out, and the two share many common interests- this is a sharp contrast to how their Prime counterparts interacted at this age. That being said, the two still butt heads occasionally.


All of the events of the Ben 10 Reboot up to but not including Omni-Tricked occurred in this dimension and therefore to this Gwen.

Ben 10: Reboot Revolution

Gwen accompanied Ben as they got lost in the woods at the start of Ten Over Ten Thousand. She helped Ben discover Ben's future self unconscious as Clockwork. Later she helped Ben 10'000 realise how Time Breaker Tetrax's time freezing powers worked.

In Chapter 1, Gwen helped Ben Prime realise he was in another dimension by explaining the discrepancies that Ben noticed between Dimension Delta and his own past.

Ben 10: Delta Days

Gwen helped Ben catch up to Smugglebeard's Crew as they raced down the Doomed Galleon ride in the episode Pirates!.
