Cluemaster in the context of "Stephanie Brown (character)"

Stephanie Brown is a superheroine appearing in American comic books published by DC Comics, most commonly in association with the superhero Batman. The character first appeared in Detective Comics #647 (June 1992), and was created by Chuck Dixon and Tom Lyle.

The character originated as the amateur crime-fighter Spoiler, who had taken it upon herself to foil her criminal father Cluemaster's schemes. Establishing herself as a Gotham vigilante, she would have a short, unsuccessful stint as the fourth incarnation of Batman's partner and sidekick Robin in the early 2000s, replacing her longtime love interest Tim Drake. Her time as Robin is plagued with struggles and dissensions with Batman, who eventually fires her shortly before her death at the hands of Black Mask. She is later revealed to have survived and returns as Spoiler, resuming her romantic relationship with Drake. In 2009, Cassandra Cain, the latest Batgirl, entrusts the costume and monicker to Brown; although she is initially reluctant due to Brown's disastrous spell as Robin, former Batgirl Barbara Gordon later takes Brown as a pupil, and the character's run as Batgirl largely redeems her, including in Batman's eyes.
