Booker DeWitt

"Booker DeWitt. An agent at Pinkerton. Now he comes to Columbia so he can stop his evil counterpart, Zachary Hale Comstock. Speak harsh words with him now, and this guy gives respect to others as well."

--Su Ji-Hoon, DeWitt

Booker DeWitt is the protagonist of BioShock Infinite. He is a private investigator and, prior to his reluctant arrival in Columbia, a former soldier and Pinkerton agent. Booker is offered a deal to wipe away his gambling debts if he goes to Columbia and retrieves a girl imprisoned there. Over the course of the story, Booker reveals his past experiences, and shows his ability to make decisions independent of the player. Unlike Jack Wells and Subject Delta, Booker has his own personality rather than being a silent and faceless avatar for the player.
