The Funko POP! x BioShock series feature characters from the first-person shooter video game, which follows former Pinkerton agent Booker DeWitt, who was sent to the floating air city of Columbia in 1912 to find a young woman, Elizabeth, who has been held captive there for most of her life. Though Booker rescues Elizabeth, the two become involved with the city's warring factions: the nativist and elite Founders that rule Columbia and strive to keep its privileges for White Americans, and the Vox Populi, underground rebels representing the underclass of the city. During this conflict, Booker learns that Elizabeth possesses strange powers to manipulate "Tears" in the space-time continuum that ravage Columbia, and soon discovers her to be central to the city's dark secrets.
