Gwen Tennyson (Classic)

Gwendolyn "Gwen" Tennyson is Ben's cousin. She's voiced by Meagan Smith, and future Gwen is played by Tara Strong. Although Ben does not like her and has nicknamed her "freak", she still helps Ben whenever he needs help. She has a huge interest in magic and she doesn't even know how big relation she has with magic. She first knew about it when she used Hex's staff in the episode Tough Luck even when Hex said that only a master magician like him is able to use his staff. She even stole Charmcaster's spell book and knew a lot of magic.
