Lieutenant Cammy White, often simply called Cammy, is a character from the Street Fighter series whose origins and role are deeply tied to the criminal organization Shadaloo. Originally created as a clone of the series' primary antagonist, M. Bison, she was designated as one of his "Dolls" and operated under the codename "Killer Bee". Her background begins in the Street Fighter Alpha timeline, where she was genetically engineered using M. Bison's DNA and trained as an assassin. During a mission to eliminate the fighter Dhalsim, his spiritual powers awakened her self-awareness, causing her to break free from Shadaloo's brainwashing. This led to a confrontation with M. Bison, who revealed his intention to use her as a vessel for his consciousness. Cammy resisted his influence, helped free other Dolls, and escaped the destruction of Shadaloo's base. She was later found with no memory of her past and taken in by the British special forces unit Delta Red, adopting the rank of Lieutenant.

Cammy's personality is defined by a blend of fierce determination and a strong moral compass. She is fearless in battle and possesses a tough, sometimes irritable demeanor, but beneath this lies a gentle, respectful, and kindhearted nature. She is driven to protect others and is deeply loyal to her teammates in Delta Red. Her search for her true identity and her past is a central motivation, though over time she learns to embrace her new life and found family. She is also known for her fondness for cats.

Her role in the story is that of a former enemy turned dedicated hero. As a member of Delta Red, she serves as a special forces operative for the British government, often investigating Shadaloo's remnants and other global threats. Her connection to M. Bison compels her to confront her past, and she becomes a key figure in the fight against his influence. Key relationships include her comrades in Delta Red, particularly her commanding officer Colonel Keith Wolfman, as well as fellow fighters Chun-Li and Guile, with whom she frequently cooperates. Her relationship with M. Bison is one of creator and created, fraught with manipulation and a struggle for autonomy. She also shares a complex bond with other former Dolls like Juni and Decapre.

Cammy's fighting style is a form of mixed martial arts enhanced by her Shadaloo conditioning and later refined by her military training. She is exceptionally agile and fast, compensating for her smaller frame with speed and lethal precision. Her abilities include powerful kicks and acrobatic maneuvers, with notable techniques such as the Spiral Arrow and Cannon Spike. She also has minor regenerative properties due to her clone origins. Despite her physical prowess, her identity is a core part of her narrative arc, as she develops from a mindless weapon into an independent and self-assured person who defines her own future.
