Gwendolyn "Gwen" Tennyson is a human-Anodite hybrid Plumber, the paternal cousin of Ben Tennyson, and (along with Kevin Levin) a front line member of his team in Ben 10: Protector of the Omniverse. She is the Timeline 1 equivalent of the canon Gwen.
She has her Heroes United appearance, but she wears an outfit resembling her Alien Force Season 3 outfit. However, her shirt is blue, her pants are white and her vest is red, and it is shaped differently, also now having a zipper. She wears a black belt with her signature cat symbol in the middle, colored light pink. She also now has bangs.
When at school, she wears her Ultimate Alien outfit.
At times she trusts others too quickly, and that may be a disadvantage or even injure her. She can handle dangerous situations, despite their often unfavorable conditions.
Gwen is at times shown to be very concerned with the well-being of things around her, such as her surroundings, the people around her, and those she cares about. She is very strong both physically and mentally and well mannered, despite her inflating sarcasm and ego at certain times. Gwen is a very caring, compassionate person, as shown by her acceptance of Kevin's past and recent actions, as well as her statements that she does not care about Kevin's appearance.
Powers and Abilities
Her mana and magic powers have slightly improved since Omniverse, as has her knowledge of martial arts.
She is overprotective of her friends and family, especially Kevin. When they are badly hurt, she will not be able to think straight, instead relying on brute force.
In Change, Gwen mostly tries to convince Ben to return to the hero business, albeit subtly. She also tries to mend Ben and Kevin's friendship by telling Ben that Kevin likes him. When the three of them meet for dinner at Max's diner, Myaxx sends them a distress call, telling them to come to Galvan Mark II as Azmuth went missing. Gwen manages to persuade Ben to come along, though Azmuth died.

- Unlike her canon equivalent, she did not go to college early.
- The cat symbol on her belt acts as a locket and contains a picture of her and Kevin inside.
