Emiko Queen

Emiko was born to Robert Queen and Shado on Starfish Island. However, as a baby, she was kidnapped by her father's protégé-turned-enemy, Simon Lacroix, better known as Komodo. Lacroix would train Emiko for years with the Outsiders' Arrow clan, leading her to believe he was her father.

Following Komodo's death at her own hands, she followed Oliver back to Seattle and joined him as his new protégé.

Together with her older half-brother Oliver, she infiltrated the docks to rescue kidnapped children. Black Canary appeared to help them and Emiko revealed she was a fan of Black Canary's. All three of them then went back to Oliver's and Emiko's apartment where Dinah stayed for the night.

Later that day, the assassin Shado snuck into Oliver's apartment and attacked him. The two got into a scuffle and Oliver ordered Emiko to get out of the apartment. Instead, she fired an arrow into his back, telling Shado afterwards, that she had been waiting for her mother to arrive.

Together, they got onto a boat, took Oliver's body with them, and drove away from the bay of Seattle out to the ocean. Once in the middle of nowhere, they threw Oliver's body over the guard rail, deep down into the ocean. They then traveled to the floating base called "The Inferno", where Shado's masters, the criminal organization known as The Ninth Circle operated.

After Oliver turned out to be alive, Emiko conducted a plan for the Ninth Circle to capture Dinah, in order to stop them from going after Shado who had fallen on bad terms with the organization after her failed assassination of Oliver. They lured Dinah to The Inferno where Emiko managed to capture her. When Emiko and Shado were supposed to kill Dinah, Emiko instead rescued her, revealing that she had been a double agent the whole time.

Moments later she met Oliver, who had infiltrated the Inferno, and told him she had been trying to help him the entire time. Emiko had slipped a homing beacon into his pocket when she dumped him into the ocean, thus helping Henry Fyff locate Oliver. She had also anonymously contacted John Diggle and had secretly revealed the location of the Inferno to Oliver. Furious over her daughter's betrayal, Shado took Emiko hostage, taking her with her in a helicopter as the Inferno exploded.

Shado took Emiko to Japan, hoping to take her to a Yakuza Oyabun (godfather) and beg for their lives. Emiko managed to escape her mother and decided to go after the Oyabun herself.

Emiko returned to Seattle, now going by the name "Red Arrow", and saved Oliver, Black Canary and the Seattle Police Department from Scott Notting and the Vice Squad.

After Robin offered her to join the team, Emiko agreed to join on the condition that if her team did not convince her she can leave. The team formed by Robin, Kid Flash, Djinn, Roundhouse and Crush had no training, but Emiko saw the potential in them and decided to stay as Robin's right hand. After their encounter with Deathstroke went awry, leading her to kill the assassin, Emiko left the team.
