History:
Talia al Ghul (Arabic: تاليا الغول) is the daughter of the late "Ra's al Ghul" and the paternal older half-sister of Nyssa al Ghul. A worldly and cultured elite warrior, Talia is the leader of her own cult of combatants, similar to the League of Assassins, as well as the mentor of Yao Fei Gulong, Oliver Queen and Adrian Chase. After her father's death Talia trained Adrian and joined his team in order to get revenge against Oliver, who killed Ra's. Her fate was left unknown after the explosions on Lian Yu, until Oliver found her in Slabside Maximum Security Prison, alive. She then revealed to him that she was the mysterious individual known as The Demon, who he'd been searching for, as she had some kind of connection to help him take down Ricardo Diaz. He and Talia later came to terms as Oliver helped her escape while Talia offered to help him expose Level Two of Slabside.

Powers:
 Despite being a child in 1960, Talia still possesses the health, performance and appearance of her physical prime of life. It is likely that she uses the Lazarus Pit to maintain her youth like her father, Ra's al Ghul.  As a highly skilled assassin, Talia is in top physical condition with fast reflexes and physical strength that is powerful enough to swiftly incapacitate men much larger than she is, such as Oliver Queen.  Talia has both sharp sight and hearing, as well as advanced skills of perception for a normal human, as she has the ability to sense and identify people sneaking behind her back without looking at them.  Talia is an accomplished acrobat, capable of scaling buildings, and running from rooftop to rooftop with ease.  As a daughter of Ra's al Ghul and a former member of the League of Assassins, Talia has been extensively trained in combat, able to effortlessly subdue Oliver Queen in their first meeting. Being the daughter of Ra's al Ghul meant that Talia was subjected to a higher level of training than most member of the League, making her skills in combat and weaponry even more advanced. She is also an exceptional teacher as her known students Yao Fei Gulong, Oliver, Adrian Chase and the members of her cult are exceptional fighters. Talia was able to defeat a group of armed correction officers with relative ease and fight for a while against Oliver now as Green Arrow (who had been personally trained by her father, Ra's al Ghul) before being subdued.  Talia used two police batons while fighting against the Slabside guards and subdued many of them with relative ease.  Talia has proven herself to be a proficient archer, firing an arrow into Ishmael Gregor's hand, which was holding a firearm, and which forced the man to drop it before his arm was pinned against the wall.  Talia is a master at using knives, being able to hold her own against Oliver with them disarming each other.  As a former member of the League of Assassins, Talia is a master swordswoman. Using her sword she was able to overpower and capture John Diggle and Felicity Smoak after having to stop their car while it was running.  Talia is highly tactical, both in preparation and while in action, able to quickly analyze the situation and how best to handle it. Talia is an exceptional investigator, as she was able to uncover evidence of the last four years of Oliver's life including the list that his father left him. She knows much about the human anatomy, as she's probably the one who taught to Yao Fei about pressure point manipulation. In terms of healing methods, Talia can patch up most injuries on herself or others, as she was able to nurse Oliver back to health after he was tortured for several days first by Konstantin Kovar's and then by Ishmael Gregor's men. She also has some knowledge of magic and mysticism, as she fully understands how the Lazarus Pit functions and is the only known person who has used it aside from her father and Malcolm Merlyn. As the leader of her cult, Talia has a group of loyal students that she trained to be effective combatants and killers.  Talia is a very effective interrogator and torturer, as she taught Oliver how to use a Mongolian skinning technique on men.  Talia is capable of fluently speaking English, Russian and Arabic.  Talia was able to sneak into and retrieve Oliver's belongings from the Bratva, which she implied was the least of her skills. Talia's stealth is further shown against Oliver as she was able to shoot him with an arrow from a close distance without him to notice her.
