Gwendolyn Tennyson is a character in Ben 10 (3x0-verse) it's succeeding series and Get Animated. She first appeared in And Then There Was Ten, and A Little Bit of Magic but is referenced before her actual cameo in 'Get Animated'. She is an Anodite originally Human from the planet Earth.


In the beginning, she had a light blue shirt with sky blue sleeves and cat face in the center of her shirt that had 3/4 sleeves, she wore white capris while she had white flats with a blue stripe across them. Gwen's hair was short with her bangs kept to the side with a blue hairclip.

In later years as a teenager, she had a white color shirt, with s blue sweater, dark reddish tights and black skirt, and dark grey shoes. Her hair is longer than in her youth. but this was mostly her school uniform as well.

Rest is in development. She will still have her signature cat symbol.


She is a smart and caring individual.

Due to being an Anodite, she can also survive in the vacuum of space, a power that she lacked as a human.
