Arrow's Main Villains Ranked From Worst To Best

8. Emiko Queen

When Oliver gets himself locked up (again) after revealing his superhero identity, a new Green Arrow sprouts up around the city in the months to follow, fulfilling the same role of protecting its citizens from ever-present criminal threats. The team find a trace of blood at a crime scene, with which they deduce that this new Green Arrow is a woman named Emiko Adachi, Oliver's paternal half-sister.

Eventually freed from prison, Oliver tracks her down and attempts to connect with her. However, unbeknownst to him until much later, Emiko is secretly the leader of a cult-like terrorist organisation called The Ninth Circle, and has been crossing targets off her 'list' much like Oliver himself did in the show's first season.

As it is revealed that Emiko's mother, Kazumi, was murdered years prior, Emiko, fuelled by her hatred of her father, Robert Queen, for abandoning them, seeks revenge on Oliver and his legacy to balance out the wrongs his family have done to her. However, her vendetta is what exposes The Ninth Circle to Team Arrow, and the organisation turns on her, eventually leading to her death.

Emiko's placing in this list is due to her last-minute redemption - something that definitely sets her apart from the entries to come. Before dying, she and Oliver are able to bury the hatchet once and for all, and she is finally accepted as part of the family.
