Slade Wilson, also known as Deathstroke, met Lillian Worth on a search-and-rescue mission a few years after his divorce from Adeline Kane. His mission was to make sure that she escaped war-torn Cambodia safely. After an intermittent love affair with Wilson, Worth gave birth to a daughter whom she named Rose. Believing it to be in the child's best interest, Worth kept Rose a secret from Wilson. Worth eventually settled down at a brothel in New York City, and during a time when Deathstroke was injured and a fugitive from the law, Worth took him in and nursed his wounds. Deathstroke's butler Wintergreen discovered 14-year-old Rose and suspected that she was Deathstroke's daughter.
Deathstroke's half-brother Wade DeFarge, using the name Ravager, later killed Deathstroke's friends and family. DeFarge discovered Rose, captured her, and told her that Deathstroke was her father. Wintergreen and Worth launched a rescue attempt, but Worth was presumed dead after she drove a jeep off a cliff while trying to run over DeFarge. Wintergreen successfully rescued Rose and escaped.
Rose tried to reach out to her father, but he turned her away. He feared for her safety because he believed himself to be responsible for the deaths of two of his sons. Deathstroke left her in the care of the Titans. During a training exercise, Rose was injured and taken to the hospital, and her precognitive powers emerged for the first time when she had a lengthy vision of Deathstroke's future. She awakened before she could test her powers further. She left the Titans shortly after and did not see them again until the Technis Imperium conflict when she allied herself with the Titans to save fellow Titan Cyborg.
The Madison family in Chicago adopted Rose, but DeFarge killed her new family. The Ravager claimed to have been offered $100,000 for her death by an anonymous source, but neither of them knew that Deathstroke hired DeFarge, in an attempt to bring Rose closer to him.
Deathstroke anonymously alerted the Titans that Rose's life was in danger, and they fought to defend her. All of the fighters were rendered unconscious by an explosion of halothane gas, and Rose awakened in Deathstroke's lair. He apologized to Rose for abandoning her and said that she was the only family he had left. Deathstroke suggested that she become his apprentice, offering DeFarge as her first kill. Rose accepted and took the name Ravager for herself. Deathstroke secretly injected Rose with the same serum that gave him his abilities, and it caused her to suffer from psychosis.
Deathstroke doubted Rose’s readiness to work with him and planned to disown her after she hesitated and was unable to kill Deathstroke’s son Jericho. To prove her loyalty, she gouged out an eye to match his missing eye; thus emulating him.
After Rose suffered a defeat at the hands of Batgirl, Deathstroke allowed her to be trained by Nightwing, who had apparently given up being a hero. Nightwing agreed to train Rose so that he could teach her to lead a better life. In order to test Grayson's loyalty, Deathstroke replaced Rose's missing eye with a kryptonite one and pitted Nightwing and Rose against Superman. Rose attempted to kill Superman with the kryptonite, but Nightwing told her that over time, the kryptonite would slowly kill her and lead to a painful death. Enraged that her father had betrayed her, Rose broke her ties with Deathstroke and ran away.
One year after the battle against Alexander Luthor and Superboy-Prime, Rose was a member of the Teen Titans. She wore the same costume and wielded two katana-style swords. She called herself a “good girl” but still exhibited violent behavior and appeared to have difficulty reining in her antisocial tendencies. With Deathstroke and his serum's influence gone, Rose appeared more balanced than previously depicted. Robin admitted Rose to the team as a favor to her former mentor Nightwing.
Rose also had a friendship with Kid Devil, the other new Teen Titan. When Kid Devil was injured during a mission, Rose defended him, and on multiple occasions threatened those she deemed a threat to him. Rose had an antagonistic relationship with Wonder Girl, and she told Kid Devil that she was afraid that if the old Teen Titans rejoined the team, she would be kicked out because nobody wanted her as a member. She also said she was afraid that if she did get kicked out, her father would find her and inject her with the serum again, making her psychotic once more.
Rose became the target of a group known as the Terror Titans who ambushed her at Titans Tower and nearly succeeded in killing her. After which, Rose elected to leave the team to infiltrate the Terror Titans and learn more about their operation.
Following the "Deathtrap" storyline, Rose briefly tries her hand at being a part of the Titans, but finds that she does not belong with them. After an altercation with Bombshell, staged to ensure her loyalty to the team, Rose leaves to find her own way in life. From Teen Titans #72 onwards, Ravager is featured in a 10-page, 9 part co-feature written by Sean McKeever.
