Beatrix Kiddo

"Looked dead, didn't I? Well, I wasn't. But it wasn't from lack of trying, I can tell you that. Actually Bill's last bullet put me in a coma--a coma I was to lie in for four years. When I woke up, I went on what the movie advertisements refer to as...'A roaring rampage of revenge.' I roared and I rampaged, and I got bloody satisfaction. I've killed a hell of a lot of people to get to this point, but I have only one more. The last one. The one I'm driving to right now. The only one left. And when I arrive at my destination, I am gonna kill Bill."

- Beatrix Kiddo

Beatrix Michelle Kiddo, also known as the Bride and Black Mamba, is the main protagonist of Quentin Tarantino's Kill Bill. She abandons her life as a hired assassin for the Deadly Viper Assassination Squad upon realizing she is pregnant with Bill's child, denying him the right of fatherhood. This action provokes the attacks on her and her loved ones and its ensuing revenge, which is the entire basis of the film.

Life as a Deadly Viper
Beatrix Kiddo was once a member of the Deadly Viper Assassination Squad, a group of highly trained assassins each working under a snake themed aliases. In the Squad Kiddo went by the name Black Mamba and worked for her employer/lover Bill, code named Snake Charmer. Each member of the squad had one area they excelled at over the others, Black Mamba's was blade master, specifically katana's as a favored weapon. Kiddo was specially trained in martial-arts by a master monk named Pai Mei and was one of only three of the six assassins who would ever receive such prestige training, along with Bill she was also the only one to complete said training. On a routine assassination assignment in China, Beatrix discovered she was pregnant and defaulted on her contract, thanks to her target's own counter assassin, who allowed her to back-out once both realized Black Mamba's baby would drive her into retirement.

Reformation
Black Mamba disappeared and dropped off the grid to escape her past completely, she set-up a new identity in Texas and picked up a prospective husband who she would pass-off as the father of her child. Bill showed up in Texas on the day of Kiddo's wedding rehearsal. Bill said he had spent a lot of time tracking her down and when he found her wanted to be there for the day of her wedding, though he was surprised to see her pregnant. Both Bill and Beatrix kept their reunion short and details of what had brought each there vague, as neither had a fondness for making a scene in front of civilians. Bill passed himself off as Beatrix's father, who had made it to give her away. To the surprise of the Bride, her prospective groom, the witnesses, Reverend, Reverend's wife and balladeer, Bill was not alone and had his entire remaining squad members march in execution style and annihilate the entire attendance. Kiddo was the last attendant to be put down. Kiddo had been badly beaten before the final blow and managed to get out that the baby was in fact Bill's just as Bill delivered a bullet to her head. The Bride survived the shot but was put into a coma from it, she was taken to a hospital and put on life support as the sole survivor. Though The Deadly Viper Assassin, Elle Driver a.k.a California Mountain Snake, would show up to finish her off, she was called off at the last second by Bill, who insisted that the one thing they would not do to her is kill her in her sleep, considering it to be a sign of weakness on the Squad's part. Though The Bride would eventually make a recovery, when she awoke she found she was no longer pregnant and that in-fact several years had passed.

Roaring Rampage of Revenge
Though angry about being stabbed, beaten and shot by her former team mates, Beatrix's loss of her child was what sent her over the edge and she made it the purpose of her remaining life to kill every single member of the Deadly Vipers Assassination Squad. Kiddo started her quest by having a sword forged by a man named Hattori Hanzō, the same man who had made a sword for both Bill and his brother Budd a.k.a Sidewinder. Hattori Hanzō swords were said to each be unique works of art and the greatest blade in the world each at their own specific style of use. Hanzō had retired from his business as well, currently working as a sushi/hibachi chief when Beatrix met him, however Beatrix convinced him to make one final sword for her when she told him she intended to kill Bill, who he had a rather serious falling out with. Once the sword was completed, Hattori Hanzō presented The Bride with his work, a sword crafted specifically to be the perfect tool for The Bride's quest.

Armed with the only type of blade she considered worthy of killing Bill and his Squad Beatrix began the main crux of her quest to wipe-out each member of the Deadly Vipers Assassination Squad, Cottonmouth - the sword-master and crime-boss, Copperhead - the knife master, Sidewinder- the gun master and tactician, Californian Mountain Snake- the trap/poison master and Snake Charmer- the Squad's leader and mastermind. The Bride took on each of her targets one by one saving Bill for the last.

Bill
Despite their mutual hatred, Bill and Kiddo were willing to debate Kiddo’s vendetta and Bill’s reasons before the final duel.

Budd
Kiddo’s and Budd’s relationship was not shown. However, despite Bill’s and Budd’s falling out, Budd stated that Kiddo emotionally wounded Bill.

Elle Driver
Driver openly stated that she despised Kiddo. However, at the hospital and Budd’s trailer, Driver openly stated that she respected Kiddo’s skill and deserved a dignified death. Kiddo’s planned death at the hospital of “dying in her sleep” would be a “luxury” and a “gift” to an assassin. Kiddo’s presumed death from Budd was deemed a dishonor as Kiddo had died at the hands of a washed-up disgraced and Driver said “that woman deserved better”.

O-Ren Ishii
O-Ren and Kiddo had a personal joke about Kiddo’s first name based on the breakfast cereal slogan “Silly rabbit, Trix are for kids”. After killing O-Ren, Kiddo dropped her sword in the snow and showed physical remorse for having to have kill O-Ren.

Sofie Fatale
Kiddo showed no personal hatred for Fatale other than her involvement in The Massacre at Two Pines.

Vernita Green
Kiddo’s relationship with Green was based on some respect as Kiddo stated Bill’s opinion of Green’s knife skills. Kiddo expressed regret that Green had died in front of Nikkia Bell.
