BB

BB is a significant character in "Fate/Grand Order," initially appearing as a major antagonist in "Fate/EXTRA CCC." She is a powerful AI, originally designed to monitor the health of Masters, but went out of control due to a system error. In "Fate/Grand Order," BB joins the player's party as a Moon Cancer-class Servant, and is beloved by players for her unique personality and abilities. She can serve as a strong damage dealer or provide support with her skills. BB's iconic appearance includes a black coat and nurse's uniform, and she often interacts with players with a mischievous and devious personality. BB's Noble Phantasms are also unique, switching between attack and defense modes, making her highly tactically flexible.
