General Info

League of Assassins logo
Faction NameLeague of Assassins
The League of Assassins, also known as the Shadows, is a powerful and ancient organization in the Arrowverse universe. Founded by Ra's al Ghul, they operate in the shadows with the primary goal of taming chaos and bringing order. Comprised of some of the deadliest assassins in the world, they operate by a strict code. Their signature weapon is a unique curved scimitar, and their hand-to-hand combat prowess is immense. However, in the eyes of heroes like Green Arrow and his team, their pursuits are not considered fair. As a result, the League encountered these vigilantes numerous times, resulting in intense and tense battles. But it's their inherent mystery and unrelenting determination that make them such a fascinating aspect of the Arrowverse universe.


The League of Assassins, also known as the Thanatos Guild, is an ancient organization created centuries ago in the Arrowverse universe. The League's primary goal is to track down and eliminate individuals deemed a danger to society, believing that doing so is for the greater good. The organization is highly hierarchical, with a single leader known as "Ra's al Ghul" whose lifespan has been unnaturally extended by the Lazarus Pit.
The league's recruitment and training practices are brutal, turning members into elite fighters. The faction is known for their superior martial arts and use of advanced weapons, making them a formidable threat. In addition, members display unwavering loyalty and are willing to sacrifice their lives if their leader orders them to.
The League has resurfaced several times, even after announcements of their disbandment, and remains a constant threat to the heroes of the Arrowverse. Cast members including Malcolm Merlyn, Sara Lance and Nyssa al Ghul interacted with the main characters, revealing intriguing narratives and power dynamics. As such, the League of Assassins makes an integral contribution to the vast tapestry of discord and justice in the Arrowverse universe. Their constant influence and old tactics continue to maintain their position as an unpredictable enemy who curates chaos.


The League of Assassins is a thousand-year-old secret organization in the Arrowverse. But much of their history remains a mystery. The league was founded around 1013. a man known as Al-Fatih. He discovered the source of the ash-like substance, namely the Lazarus Pit, which was known to have regenerative properties capable of resurrecting those who were close to death or even actually dead.
Al-Fatih was an Arab nobleman, the first person to own the waters of the Pits of Lazarus. His discovery was profound and he realized that he had been entrusted with a great responsibility. Intuitively, he founded an order of warrior assassins whose mission was to manipulate major human events and maintain the balance of civilization.
Under the leadership of "Ra's al Ghul," which translates as "The Demon's Leader," the League orchestrated the most important historical events behind the veil. The League has been involved in many historical incidents over the centuries. Their hand has been suspected in everything from toppling empires to fomenting world wars in the name of their disturbed sense of balance and justice. The League's power remained unchallenged for centuries, especially since those who dared to challenge it were quickly removed. They were everywhere, reading the journals of power from castles to boardrooms and writing their own history. The League created fear in all dimensions and small times that did not fit their ideology.
In 2014, Oliver Queen, known on the street as the vigilante "Arrow," caught the league's attention. He soon became entangled in their web of power plays and deceit, drastically altering the Millennium League's power. After many battles and alliances, the Queen eventually assumed the role of Ra's al Ghul herself, a significant departure from the long line of succession. Green Arrow's tenure as leader was short-lived, but the ripples didn't end there.
Over the years, the league has seen several leaders, each of whom left their mark on history, contributed to the glory, increased their influence and shaped the operation. Some maintained the old customs and traditions of the League, while others introduced reforms that significantly changed its function and goals.
However, the league's control was not permanent. Reign of Terror ended when Nyssa Al Ghul, daughter of Ra's al Ghul, disbanded the League, marking the end of an era for one of the most powerful organizations in the Arrowverse. Even after its disbandment, the League of Assassins' influence continues to permeate the fabric of the Arrowverse.
