Honestly, there wasn't a favorite fandom before Harry Potter. Harry Potter has been my whole life (or very close to my whole life), but there are other fandoms I'm a fan of. I suppose I would say Chris Halliwell from Charmed.
Obscure; yes. One of the hottest characters on the show; heck yes. From his adorable brown hair to his voice, Chris seriously stole my heart (even when the sisters and Leo thought he was evil, which he totally wasn't; he was trying to change his future).
