The Deadly Viper Assassination Squad is the main antagonist organization in Kill Bill.
The Deadly Viper Assassination Squad was a group of assassins led by Bill. The group was composed of two men and five women: Bill, his brother Budd, Beatrix Kiddo, O-Ren Ishii, Vernita Green, Elle Driver, and Sofie Fatale.
Although their name suggests that the members of the team are codenamed with vipers names, the black mamba and the California mountain snake do not belong to the viper family; the black mamba is an elapid and the California mountain snake belongs to the colubrids.
The Codenames of all members but Bill are the names of snakes. Bill's codename is Snake Charmer and hence signifies him as the leader of the squad.
However, not all members are named after Vipers as the name of the squad suggests. The Black Mamba and the California Mountain Snake do not belong to the Viper family.
Massacre at Two-Pines Wedding ChapelEdit
After discovering she was pregnant, Beatrix Kiddo quietly left the vipers. Beatrix intended to settle down and start a new life in El Paso, Texas. Upon learning she was still alive, Bill tracked her down and ordered the remaining vipers to storm the chapel and kill everyone except Beatrix. Each of the four beat the helpless Beatrix and stood over her body, while Bill approached Beatrix and shot her in the head.
