Which Batman family member is shot by the Joker in Arkham Knight?

The Batman family member shot by the Joker in Arkham Knight is Barbara Gordon. In the Arkham continuity, Barbara operates as Batgirl before becoming Batman’s communications and intelligence specialist, Oracle.

The shooting is rooted in one of the most famous Batman stories, The Killing Joke, in which the Joker shoots Barbara and paralyzes her to torment her father, Commissioner James Gordon. Arkham Knight adapts this history through Batman’s memories and psychological experiences while he confronts the Joker’s legacy. Barbara’s injury is a major part of her character arc and helps explain her transition from front-line crime-fighter to Oracle.

The game also deliberately blurs memory, hallucination, and reality because Batman is infected by the Joker’s blood and fears becoming like him. That presentation can make the scene confusing, but the intended answer remains Barbara Gordon. Dick Grayson, Tim Drake, and Jason Todd are also members of Batman’s extended family, yet none is the family member associated with this shooting.
