Beatrix "The Bride" Kiddo (codename: Black Mamba) is a fictional character and the protagonist of the two-part movie "Kill Bill" directed by Quentin Tarantino. She is portrayed by Uma Thurman.

Kiddo is a member of the Deadly Viper Assassination Squad, an elite, shadowy group of assassins. She is trained by martial arts master Pai Mei and becomes the right hand of Bill, her boss and lover, provoking the envy of fellow Viper Elle Driver.

When she discovers she is pregnant with Bill's child, Kiddo abandons the Deadly Vipers so her baby can have a better life and becomes engaged. Bill, assuming her fiancé is the father, orders them assassinated at the chapel and shoots her in the head.

Kiddo survives and falls into a coma. Bill aborts an order to have her assassinated in the hospital, considering it dishonorable when she cannot defend herself. Kiddo awakens from the coma and is horrified to find that she is no longer pregnant. She tracks down the Deadly Vipers, including O-Ren Ishii, now the leader of the Tokyo 'yakuza', and exacts revenge.

In Mexico, Kiddo tracks Bill to a hotel and discovers that their daughter B.B. is still alive, now four years old. Kiddo kills Bill using the five-point-palm exploding heart technique, taught to her by Pai Mai. Beatrix leaves with B.B. to start a new life.
