First Appearance Marvel Future Avengers

Gwendolyn "Gwen" Tennyson is an Anodite, the paternal cousin of Ben Tennyson and is a main member of his team.


Gwen has short orange hair held by a blue hair clip and green eyes and wore a blue raglan shirt with a cat logo on her chest, white capris, and a pair of white shoes with dark blue stripes.


Gwen is an intelligent, mature but usually stubborn and smart-mouthed when it came to talking with Ben. Her quick thinking and good instincts give her an edge in dealing with dangerous situations. However, she's sometimes too trusting with people who want to exploit her good will, leading her (or others) into harm's way.


Before Marvels Future Avengers, Gwen went on a road trip with Grandpa Max and her cousin Ben. She and Ben constantly argued (like about Ben misusing the watch or about Gwen's powers) however they were shown to deeply care for each other. Gwen also shows deep affection for her Grandpa.

Gwen also uses newspapers and her laptop to research any strange people and creatures they might come across. She is a capable gymnast and has had some training in martial arts.

She is depicted as snobbish due to her young girl attitude. Overall, her most notable skill is her innate, if latent, ability at magic. Having within her what Dr. Strange calls a "magical aura", Gwen is capable of using various magical artifacts, charms, talismans, and spells.

Gwen starts tapping into magical powers when she procures a small book of spells.

Gwen forms a rivalry with Chloe during the series.
