Stephanie Brown is a vigilante in the Bat-Fam. She's the daughter of Arthur Brown, who's known as the supervillain Cluemaster, which caused her to become the vigilante Spoiler as a way to foil his schemes. Strong-willed and unpredictable, she initially had a turbulent relationship with the Bat-Fam, despite a long history with Tim Drake, and endured a brief and difficult spell as Robin. She sprouted into the hope-inspiring Batgirl role with Barbara Gordon as her mentor, who was the predecessor.
