Gwendolyn Tennyson

Gwendolyn Tennyson is the future version of Gwen Tennyson.

Appearance
Gwendolyn has short orange hair with a fringe on the front. He wears a blue and black spandex suit and the Bezel Spells on his right arm. She has a hood and only sometimes uses it. She has a belt with a cat on it, the same cat Gwen had on her shirt when she was ten years old.

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

In The End of an Era, she looks more like what she looked like in Ben 10,000. However, the lines in Bezel's Spells are thicker, and pink. The cat symbol on its belt has a different shape, with pointy ears and pink eyes. His shoes now have white fingers and soles. She also has blue freckles and earrings.

Ben 10
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 Ken 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.

Ben 10: Omniverse
In The End of an Era, she attends Max's retirement party with Kevin. When the electricity goes out, she helps the other guests to evacuate. She helps Ben and Kai to fight against Maltruant, but ends up being temporarily frozen in time.
