gwen tennyson

Cousin of the titular hero in Ben 10 and its sequels. Casually known as Gwen.

In the original series, she has short orange hair and green eyes, and wears a hairclip and a shirt with raglan sleeves. In Ben 10: Alien Force, she has long hair instead and wears a sweater with a skirt. In the post-timeskip sequels, she becomes Kevin's girlfriend.

Due to the broader cultural impact of the original series over its sequels, depictions of Gwen generally skew towards her 10 year old self or make reference to it, over her 15+ year old self (or even 30+ year old self from the original's future episodes).
