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.
Arrowverse
The fictional universe began with "Arrow", based on the character Green Arrow, which debuted in October 2012. It was shortly followed by "The Flash" in 2014, and the animated web-series "Vixen" in 2015. The universe was expanded in 2016, when in January of that year a new series titled "Legends of Tomorrow" debuted, which would star characters who originally appeared on both "Arrow" and "The Flash". The universe then expanded yet again later that year when the CBS series "Supergirl" was moved to The CW for its second season, where it has remained. A second animated web-series, "", was released in 2017, which followed Ray Terrill / The Ray, who would make a live-action appearance during that year's crossover event "Crisis on Earth-X". In addition to the live-action and web-based series, the universe has spawned three promotional tie-in live-action web series, "Blood Rush", "Chronicles of Cisco", and "The Flash: Stretched Scenes"; released in 2013, 2016, and 2017 respectively. Since 2014, there has been a yearly crossover event involving many of the live-action series of the Arrowverse. Additionally, Matt Ryan has reprised his role as John Constantine from the NBC series "Constantine", in guest appearances in episodes of "Arrow" and "Legends of Tomorrow", before becoming a series regular for the latter.
