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.

In April 2015, to celebrate the season three finale of "Arrow" and season one finale of "The Flash", The CW released a short promo titled "Superhero Fight Club". The short features characters from "Arrow" and "The Flash" battling each other in a hero vs. villain showdown. Characters include The Arrow, Flash, Arsenal, Black Canary, Dark Archer, Reverse-Flash, Captain Cold, Heat Wave, Firestorm, Ra's al Ghul, and Atom in a cage match fight, with Black Canary and Arsenal vs. Dark Archer, Arrow vs. Ra's al Ghul, Flash vs. Captain Cold and Heat Wave, which is interrupted by Reverse-Flash, until Firestorm intervenes and the Atom makes an appearance at the end. In September 2016, The CW released the promo "Superhero Fight Club 2.0" to promote the start of the 2016-17 season with the addition of "Supergirl" to their lineup, as well as their new mobile app, where the promo could exclusively be viewed initially. The new Superhero Fight Club sees Green Arrow, Flash, Atom, Firestorm, White Canary and Supergirl go up against a new fight simulator created by Cisco Ramon and Felicity Smoak, while John Diggle and Martian Manhunter observe. After defeating the simulator, Cisco releases Gorilla Grodd into the arena for the heroes to face. In January, 2018, The CW released the promo "Suit Up", featuring the various heroes putting on their costumes in order to promote the return of "Arrow", "The Flash", "Legends of Tomorrow", and "Supergirl" from their first mid-season break, as well as the premiere of "Black Lightning".
