Nyssa al Ghul (Katrina Law) is a deadly assassin appearing in Arrow and Legends of Tomorrow. Her existence was first hinted at in the Arrow episode “League of Assassins”, when a member of the League of Assassins refers to “the child of Ra’s al Ghul”. She first appeared on-screen in Season 2 of Arrow, when it was revealed that she had saved the life of Oliver Queen’s ex-girlfriend Sara Lance, later recruiting her into the League and becoming her lover. Nyssa spent much of the season attempting to recruit Sara back to the League, before later teaming up with Oliver and his allies to take down their mutual enemy Deathstroke.
The majority of the romance with Sara occurred completely off-screen and many fans felt that it was handled in an offensive manner. In the first episode in which Nyssa appeared, Sara was made to “choose” between returning to a life of evil with her killer lesbian ex-girlfriend or to stay as part of Team Arrow alongside the straight, male hero love interest. Despite the fact that Nyssa kidnapped Sara’s mother in order to compel her to come with her, Sara was able to get Nyssa to let her mother go and release her from League by poisoning herself and then convincing Oliver not to kill Nyssa, who then left. In the aftermath of the episode’s events, Sara and Oliver began a relationship, but Sara left him to return to the League with Nyssa in the finale of Season 2. When Sara appeared again in the first episode of Season 3 without Nyssa, she was immediately killed.
In Season 3, Nyssa raged against Oliver when she found out about Sara’s murder, deciding to train Sara’s sister Laurel Lance to follow in Sara’s footsteps. Nyssa was later forced into a marriage with Oliver part of her father Ra’s al Ghul’s scheme to recruit a worthy successor; Nyssa and Oliver eventually killed him together. In Season 4, she opposed Laurel’s reckless scheme to resurrect Sara using the Lazarus Pit, but was delighted when a resurrected Sara was eventually restored to sanity. Nyssa also took her revenge on Sara’s killer by taking control of the League and disbanding it.
Nyssa reprised her role in the Legends of Tomorrow episode “River of Time”, where she once again appeared alongside Sara Lance. It was also revealed that Nyssa’s first meeting with Sara was the result of a Bootstrap paradox, as the 2016 version Sara became marooned in 1958 and rejoined the League until 1960, when her friends came to rescue her. Before leaving, Sara told Ra’s to send his yet-to-be-born daughter Nyssa to Lian Yu in 2008, where she knew Nyssa would meet the 2008 version of Sara.
