Green Arrow
Green Arrow is a fictional superhero who appears in comic books published by DC Comics. Created by Mort Weisinger and designed by George Papp, he first appeared in "More Fun Comics" #73 in November 1941. His real name is Oliver Jonas Queen, a wealthy businessman and owner of Queen Industries who is also a well-known celebrity in Star City. Sometimes shown dressed like the character Robin Hood, Green Arrow is an archer who uses his skills to fight crime in his home cities of Star City and Seattle, as well as alongside his fellow superheroes as a member of the Justice League. Though much less frequently used in modern stories, he also deploys a range of trick arrows with various special functions, such as glue, explosive-tipped, grappling hook, flash grenade, tear gas and even kryptonite arrows for use in a range of special situations. At the time of his debut, Green Arrow functioned in many ways as an archery-themed analogue of the very popular Batman character, but writers at DC subsequently developed him into a voice of left-wing politics very much distinct in character from Batman.
Felicity Smoak
DC Comics rebooted its comic properties in 2011 as part of a relaunch entitled The New 52, which led to the character of Felicity Smoak being brought back in a fashion similar to the version seen on "Arrow". The New 52 version of Felicity Smoak is introduced in 2014 in "Green Arrow" #35, the first issue of that book to be written by "Arrow" showrunner Andrew Kreisberg. In #35, she is introduced in an end-of-issue cliffhanger as an assassin out to kill Oliver, but quickly explains that while she is a hacker-for-hire who has "done questionable things" in her past, "leading a hero to his death isn't one of them", explaining she did not know her target was the Green Arrow when she accepted the job. After proving her hacker credentials by explaining to him that she knows his secret identity, as well as highly specific details from his superhero, personal, professional and family lives, she offers to become a part of his team out of a desire to help him save the city. Surmising that whoever hired her to kill Oliver has extremely evil plans, she teams up with Green Arrow to track down her client's other target, a woman named Mia Dearden, who they soon discover is being pursued by the deadly archer Merlyn.
