Gwendolyn Tennyson is a version of Gwen Tennyson from the Alternate Ben 10,000 Timeline.


Gwendolyn has short orange hair that has bangs in the front. She wears a blue and black spandex suit and the Charms of Bezel on her right arm. She has a hood and only sometimes wears it. She has a belt with a cat on it, the same cat Gwen wore on her shirt when she was ten.

Gwendolyn + Kenny

Gwendolyn in Ken 10.

In Ken 10, Gwendolyn has much longer hair in a ponytail.

Ben 10Edit

In Ben 10,000, 30 year old Gwendolyn came through a portal to the Main Timeline and grabbed Gwen to lead XLR8 into her timeline. When Ben and Gwen were there they believed the "crisis" Gwendolyn was talking about was Vilgax and Dr. Animo. At the end of the episode Gwen realized that Dr. Animo was never the crisis, Ben 10,000 just needed a major attitude adjustment.

In Ken 10, 42 year old Gwendolyn appeared as a hologram and gave Kenny a Stone Creature as a birthday present. Later in the episode, she and Ben 10,000 were discussing whether or not Ben 10,000 should let Ken fight.



  • According to herself, Gwendolyn started going by Gwendolyn instead of Gwen since college.
