Talia al Ghul (Earth Fifty)

"Hello, Mr. Queen. My name is Talia."

- Talia to Oliver

Talia al Ghul is a female Human in the 24th century who is the daughter of Ra's al Ghul and the half-sister of Nyssa al Ghul and ally of Laurel Lance and her team. A worldly and cultured elite warrior that never stays in a place very long, Talia was the mentor of Yao Fei Gulong, Oliver Queen and Adrian Chase. Talia became a vigilante and used Tigress as her code-name.

Early life
In 1960, Talia and her father, Ra's al Ghul, passed Sara Lance training with the best performance. Her father advised her to learn from Sara's skills. As she grew up, Talia's relationship with Ra's became strained, and because of that, she left to her own path.

Over the years, Talia maintained her youth due to the Lazarus Pit's waters and, at some point in her life, she trained Yao Fei Gulong which then became the first mentor of Oliver Queen.

In 2373, after learning of the death of her disciple, Talia decides to track down Oliver, uncovering evidence about him for the following four years.

In Russia
Decades later, in 2378, Talia found her way to Russia, saving Oliver Queen from Bratva Pakhan Ishmael Gregor. She took and had Oliver recover at her place, then she offers to help him take down Kovar by targeting one of his main suppliers, Misha Yurievich who was behind human trafficking in Kovar's organization. Oliver accepts Talia's help and they raid and kill Yurievich and his men. After this, they return to their hideout, where Talia convinces Oliver to rekindle his determination to complete his father's mission reminding him that he has left him a list of "all the Kovars" of his Starling City and giving him a green hood and suit, along with a bow. Then she offers to train him and teach him to come to terms with the monster inside him.

Later, Talia helps Oliver to track down and kill Hideo Yamane, an individual on his father's list and one of the main drug lords of Starling City, while he was in Russia for his business. After this, she encourages him to talk to Anatoly in order to leave Bratva and come back to his city to begin his mission.

Talia would eventually tell Oliver about her father, Ra's al Ghul. The stories were apparently so horrifying, Oliver stated if even half of those stories were true, anyone who crosses him would be killed.

Connection to Prometheus
After 2378, Adrian Chase, prior to the beginning of his crusade against Oliver Queen as Prometheus, was trained by Talia and learnt several specific moves that she taught to the aforementioned. When Oliver found out about a possible connection between Talia and Prometheus, he tried tracking her down in the hopes of discovering the latter's identity, though he mentioned to Diggle that she never stays in one place very long. As he eventually finds her, Oliver goes to her monastery to enquire about Prometheus, only to find out that she knew Prometheus's plan all along and helped him. When she and Oliver meet, she reveals to him her full name and that she is Ra's al Ghul's daughter, stating that she helped Prometheus because of her father, who was killed by Oliver nine years prior, and yearns to make him pay by making him suffer.
