Thanks to the continuity changes from the relaunch, Barbara’s horrifying encounter with the Clown Prince of Crime occurred only a few years earlier, and after going through an experimental surgery, she regained her mobility and started beating up bad guys as Batgirl again, though she still mentally struggled with the trauma of nearly being killed by The Joker.
It was only when The New 52 began in 2011 that Barbara finally reclaimed the Batgirl mantle.
Although Barbara Gordon is often serves as Batgirl in various media projects, she actually didn’t use the identity in the comics for over 20 years.
After being crippled by The Joker in Alan Moore’s The Killing Joke, writers Kim Yale and John Ostrander brought her back in the Suicide Squad book as Oracle, who continued to fight crime from her wheelchair as a computer hacker and information broker for the other DC heroes.
