The Spoiler (Stephanie Brown)

Stephanie is a purple-clad teen who stumbles into a meeting between her father, the Cluemaster, and his criminal associates. She manages to escape their murderous plot, and over the course of the series, works to "spoil" her father's plans by becoming a vigilante, calling herself the "Spoiler." At first, she merely attempts to spread news of the Cluemaster's plans on the internet, then works actively as a costumed crimefighter to capture and foil him.

After Red Robin is "killed" by Jacob Kane's Colony drones, Stephanie becomes depressed and questions her purpose and the world she wants to live in the "Victim Syndicate" storyline. The story ends with her challenging the rest of the team and threatening to expose their secret identities if they don't give up their vigilantism. After disarming her by refusing her offer, she leaves the team and tells Batman that until he gives up his cowl, she'll be standing in his way. Stephanie actively opposes Batman and his allies in the field. It also appears that she is falling under the influence of Anarky, who is attempting to build a (literally) underground society of people who were impacted by Batman's activities.

Eventually, Stephanie sees through Anarky's lies and helps Batman apprehend him. However, she walks away from Batman before he can tell her that Tim Drake is still alive. She is overjoyed once she finds out Tim is alive and briefly rejoins the team to help them stop the Victim Syndicate. At the end of the storyline, she leaves Gotham and breaks up with Tim as Tim's too committed to his duties as Robin to the point where he dropped out of his Ivy University scholarship behind Stephanie's back.
