Batgirl’s Controversial Gotham Knights Biography Has Been Reworked
Warner Bros. Montreal has altered Batgirl’s biography in Gotham Knights following backlash about the game’s explanation for her paralysis recovery.
Batgirl AKA Barbara Gordon is one of Gotham Knights’ four playable characters alongside Nightwing, Robin, and Red Hood in a story that sees the Bat family defending Gotham after Bruce Wayne’s death. In the 1988 comic story The Killing Joke, Barbara is famously shot through the spine by the Joker, paralyzing and confining her to a wheelchair for many years in which she lent tech and information support to Batman as Oracle. In DC's 2011 New 52 comic reboot, Barbara regains her mobility due to an experimental surgery followed by physical therapy/training.
Per Eurogamer, Gotham Knights’ original website biography for Batgirl vaguely references these events. It doesn’t mention the Joker or a specific culprit, but the offending bit was the implication that Barbara overcame her disability just by training hard.
