Spoiler (Stephanie Brown) is a DC Comics costumed hero, part of the "Batman Family". She first appeared in Detective Comics #647.

Stephanie Brown was born the daughter of the Cluemaster, one of Gotham City's third-rate villains. He spent most of her childhood in jail or away from the family. And when he returned to Gotham, "rehabilitated," Stephanie became furious that he was returning to crime without his need to leave clues behind. She decided something needed to be done.

Stephanie made a costume for herself, and called herself the Spoiler. She knew where her father was hiding out, found out his plans, and left clues so that the police and Batman could stop him. Robin tracked her down, and she joined in on the capturing of Cluemaster.

Each time Cluemaster would escape or start some new plan, Stephanie would don her costume again. Eventually, she decided she liked being a hero, and began regular patrols as Spoiler. This also brought her into regular contact with Robin, on whom she had a bit of a crush. The two worked as sometimes partners for a time, but eventually, romance blossomed.

Unfortunately for Stephanie, she found out she was pregnant by a boyfriend who had run from Gotham after an earthquake. Robin, in his false alter ego as Alvin Draper, took Stephanie to Lamaze classes, and the two became even closer. He returned to her when she was giving birth, even though he had moved away, and the two shared a few sweet moments together. With Robin's help, she was able to deal with giving her child up for adoption. Robin was then sent away to boarding school by his father, and the two were forced into a long distance relationship, made even more complicated by the fact she still didn't know his real name.

During his time away, Batman approached Spoiler and offered to train her. He also told her Robin's real name, and this betrayal by Batman, drove a wedge in between the two for a time. Spoiler not only trained with Batman, but with the Birds of Prey, and began a friendship with Batgirl.

Stephanie and Tim, as she now knew him, reconciled, and the bond they shared was stronger then ever. Even after Batman - having decided that she wasn't really hero material - told her to hang up her costume and the Birds stopped mentoring her, she still patrolled with Robin, as well as went on regular dates. When the US government came to Stephanie and her mother, and told her that Cluemaster had died in the service of his country, Stephanie was shocked. She cut off ties with Tim, and went on a crimefighting rampage, hunting down the Riddler, her father's former associate, to try to get a better idea of who he had been in life. Eventually, she made peace with his memory, and she and Tim rekindled their relationship. During Tim's battle with the occult hitman Johnny Warlock, Stephanie was injured, her leg broken, and Tim took personal responsibility.

Stephanie snapped Tim out of his funk, just in time for his father to find out he was Robin. Tim was told to hang up his cape, and he did. Shortly after, Stephanie snuck into the Batcave in a handmade Robin costume, and Batman decided to make her the new Robin. He trained her hard, and she went out with him for a time. Unfortunately, due to her disobeying his orders, Batman stripped her of the Robin costume and told her that she was done being a hero.

This led directly to her stealing one of Batman's long-range plans for dealing with the entirety of Gotham's criminal underworld, in an effort to prove her worth. Since this plan was predicated on the involvement of "Matches Malone" (who was, unbeknownst to her, a persona that Batman used for infiltration purposes), it quickly spun out of control. Stephanie was captured by Black Mask, who tortured her to death.
