Emmett Cullen was turned into a vampire by Rosalie Hale. Rosalie, a vampire who was herself turned by Carlisle Cullen, found Emmett as a human in the woods after he had been severely injured by a bear. She was immediately drawn to his strength and beauty, and after he died from his injuries, she begged Carlisle to turn him into a vampire.
Carlisle, who is a vegetarian vampire, initially hesitated because he knew Emmett's bloodlust would be difficult to control. However, Rosalie's persistence and Emmett's own desire to live led Carlisle to agree.
Rosalie's decision to turn Emmett was a significant event in the Twilight saga, as it brought a powerful and loyal member to the Cullen family. Emmett's strength and humor became integral to the family dynamic, and his presence helped to strengthen the bond between the Cullens and Bella Swan.
