Does Bella Swan become a werewolf?

No, of course not. From where the heck did that idea enter you? Bella starts of as a human being from Twilight to most of Breaking Dawn. Then, she gets married to Edward Cullen, a vampire. She then gives birth to a half-human and half-vampire child, Renesmee Cullen. After that, Bella almost dies of having Renesmee that Edward injects his venom into Bella and turns her into a vampire. Bella never turns into a werewolf in the books, and never will. Jacob Black and his clan of werewolfs are werewolfs, but not Bella Swan!
