The fan-favourite DC Comics character has been apparently returned to her former superhero identity, reports Bleeding Cool.
An entry in the recently-published DK kids encyclopaedia Batman: The World of The Dark Knight has revealed the fate of the absent hero.
"After a stint as Batgirl, Stephanie has returned to her identity as Spoiler," reads her entry in the book.
Brown briefly took on the role of Robin in pre-New 52 continuity. After her apparent death, she returned as Batgirl only to be replaced by Barbara Gordon during last year's relaunch.
She was in line to appear as Nightwing in the Smallville Season 11 comic, but the role was also given to the more well-known Gordon.
