The characters and/or events in the storyline depicted in this article have been changed, altered, added to, or erased from the main continuity.
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.
In Ken 10, Gwendolyn has much longer hair in a ponytail.
, 30 year old Gwendolyn came through a portal to the Ben 10,000 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.
, 42 year old Gwendolyn appeared as a hologram and gave Ken 10 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.
