Gwen Tennyson (Ben 10)

Gwendolyn Tennyson is the powerful cousin of Ben Tennyson. She is an Anodite which is basically a being made up of pure mana. She mostly spends time in her human form though and finds herself often running around with her cousin in his various alien forms. She also is known for dating Kevin Levin a guy who can absorb materials and use their components as armor. She also has a sort of rivalry with Charmcaster, but after working together with her, she’s more like frenemies with her? It’s complicated.
