DC Comics

DC Comics, Inc. is an American comic book publisher. It is notable as one of the largest as well as most popular comic book publishers today. DC Comics produces material featuring a large number of well-known characters, including Superman, Batman, Wonder Woman, The Flash, Green Arrow, and others.

DC Comics owns the rights to Green Arrow, Flash, etc. and so has power over Arrow, The Flash, Constantine, Supergirl, Vixen and DC's Legends of Tomorrow, allowing the showrunners to use only particular characters on the shows.

General impact of the Arrowverse in DC Comics and other media
In Green Arrow #0 (2012), which is an origin story set five years in the past, Tommy Merlyn is introduced as Oliver's best friend. The character is an original creation of the TV show's writers, while also being partly inspired by the comic book character, Merlyn. His introduction into the mainstream comics came a month after the character's official appearance on the TV show. In this particular issue, during the hostage crisis on a Pacific Ocean oil rig that resulted in Oliver shipwrecking on the island, Tommy is caught in an explosion and is thought to have been killed. In the present day at a monastery on a pacific island, a badly burned Tommy, branded as the "Mystery Patient", awakens from his coma. The character subsequently makes cameo flashback appearances in both Green Arrow #26 and Secret Origins #4 (2014).

In Green Arrow #25 (January, 2014), titled "The Prodigal", which takes place six years in the past, Moira Queen makes her debut in the New 52. In this issue, the character's history is noticeably revised by writer, Jeff Lemire, to be on par with the most recent version of the character in Arrow, which was the first to feature the character prominently. Elements like, Moira outliving her husband, running the family's company and knowing her son's secret life, which were featured for the first time on the show, were added to the comic book canon (prior to the New 52 both Moira and her husband were killed by lions in a safari in Africa when Oliver was just a child). As it was later revealed in Green Arrow #28 (April, 2014), Moira passed away from an illness during Oliver's first years as a vigilante. This is similar to the show, where Moira died during the second year of Oliver being The Arrow, though the cause of her death there was different.

The drug, "Vertigo", that is originated from Arrow is featured in the comic book Smallville Special: Titans, when Rose Wilson uses it on Mia Dearden a.k.a. Speedy, Green Arrow's protégée, during a battle.

On Green Arrow #24, John Diggle, an original character created exclusively for the TV show, made his debut in the comics, on the main Green Arrow title during writer Jeff Lemire's run on the series.

''“...I have to say, I really liked it, and especially Diggle is the breakout of that show, I think. So I knew if I could bring in some elements, I wanted to bring in Diggle.” Lemire said after watching Arrow''. ''“...You know, it's a great character, and it serves a real purpose in that mythology. He has a real role. He's someone who grounds Oliver Queen. He's a mentor and a partner and all of these things. So he has a real place within that mythology. I hope, if I'm doing my job well enough, that he'll become indispensable to the comic universe as well.”'' Lemire added. The writer also elaborated on the characters differences and similarities with his TV counterpart: ''“...I wanted the character to be the same character, and just the situations are different. So Diggle's military background and his relationship with his brother and the loss of his brother are two things that really define that character. So I felt like those were two things that I needed to bring into the comic book universe as well. The circumstances around his brother's death are obviously different, but that's something that ties into who he is and what's motivating him in the comic as well.” “We always wanted Diggle to become...something that could live on beyond the show.”'' Andrew Kreisberg mentioned during his initial discussions with Lemire.

Executive producer Andrew Kreisberg and writer Ben Sokolowski were tapped to take over DC's Green Arrow comic, beginning with issue #35, a six-chaptered storyline titled, "Kingdom" :

“We really want to bring the old-school Oliver Queen voice back to the character.” Sokolowski said. “In other words, the opinionated, liberal Robin Hood-esque hero that has fallen through the cracks a bit, both in the comics and TV models.” “Some of our favorite Arrow characters will feature prominently in the comic.” Sokolowski said. ''“Though they may not necessarily be clones of their TV personas. I think our goal with this comic is to make it an echo of the TV series.” As for Oliver Queen, “I think the version Ben and I are going for now is an amalgamation of the TV version and his comic book persona.”'' Kreisberg said.

Kreisberg also noted that he and Sokolowski approached DC about writing the comic: “We thought there was a real opportunity here not to do another adaptation of the TV show, but infuse the comic world of Oliver Queen with some of the stronger elements of the show.” he said.

In the epilogue of issue #35, the first issue of the new run, Felicity Smoak made her debut in the New 52 continuity. The character was not the original version, who debuted in Firestorm #23 (1984), but the revamped version of the comic book character, who debuted in the first season of the TV series (2012). With the previously introduced John Diggle, Kreisberg and Sokolowski established the new status quo of Team Arrow, using exactly the same characters as on the show. Both Diggle and Smoak were used prominently in that run.

On issues #36-#37 (2015), Tommy Merlyn reappeared, for the first time under the alias of the mercenary archer, "Merlyn", in the New 52 continuity. He is employed by John King to retrieve his daughter, Mia Dearden, for him. This brings him at a direct conflict with Green Arrow, whom he later confronts. The two men fight each other, with Tommy being nearly a match for Green Arrow. During their confrontation. Tommy recognizes that his opponent is actually his old friend, Oliver and decides to retreat. Even though Tommy was eventually used as a red herring on the TV show and the character who ended up being the show's version of Merlyn was his father, he remained as the mainstream version of the character in the comic books up until before the DC Rebirth relaunch.

The main antagonist of the "Kingdom" story arc is a new character named, John King, who displays many similarities with an Arrow character, Malcolm Merlyn:
 * 1) Both characters are initially presented as successful businessmen with nefarious secret plans. This is evident especially during Malcolm's appearances in the first season of the show.
 * 2) They are both the biological fathers of Mia Dearden in their respective continuities; Thea Dearden Queen is Arrow's version of that character.
 * 3) John's last name is also a reference to "Arthur King", the original alias, Merlyn used in the comics.
 * 4) King is depicted in the comics with the likeness of actor, John Barrowman, who portrays Malcolm on the show. King's first name could also be a nod to the actor.

Kreisberg and Sokolowski's run ended with issue #40, which was the conclusion of the "Kingdom" storyline. While elements from the TV series were removed from the comic book after that issue, including both characters of Diggle and Smoak.

Felicity Smoak also appeared in the out-of-continuity digital series, DC Bombshells, which takes place in an alternate history version of World War II. There, the character was once again modeled after Arrow ' s re-imagined version, while also her Jewish heritage was denoted.

In the miniseries, Superman: American Alien, which is an out-of-continuity revisioned take on Superman's origin, Jimmy Olsen is introduced as an African-American character. The character's race was changed for the first time in the Supergirl TV series.

Following DC Rebirth, Green Arrow's costume was redesigned to resemble the one wore by the character on Arrow, specifically the one that was first featured in the 4th season of the show.

The relaunch of the Green Arrow title as part of DC Rebirth, written by Benjamin Percy, also brought the character of John Diggle back. John made his reappearance in the second issue of the sixth volume, and has been part of the title since then.

In the 14th issue of Green Arrow (vol. 6), Malcolm Merlyn is introduced as the mysterious archer trying to frame Green Arrow for his own crimes. In previous issues, Oliver suspects that the mysterious "arrow killer" is his childhood friend, Tommy Merlyn, whom he previously briefly encountered. However it is revealed that the impostor is Malcolm Merlyn, the original Dark Archer, member of the League of Assassins and Tommy's father. In subsequent issues, Oliver's history with the Merlyn family, Malcolm's antagonism with Robert Queen and his romantic interest on Moira Queen, all elements first featured on Arrow, were also introduced.

Following DC Rebirth, the Supergirl comic book series was relaunched with its seventh volume borrowing several elements from the TV series. Writer of the series, Steve Orlando, had this to say about the connection to the TV series :

''“I think it’s very important to sync up with the show, but also that’s a bit of a trick question, because the show has done so well for the very reason that it truly understands the tone of the best Supergirl comics. So it’s a bit of a circle: hope, positivity, inspiration. These things run through the show, fuel the tone, but they’re right from the comics. Individual details may vary. Characters may vary. But the heart of the show is the heart of the comics, it’s what makes Supergirl unique, and getting that right is our obligation across all mediums.”''

''“...We’re moving her to National City. We’re connecting her to Cat Grant in a new way. We’re connecting her to her human parents, the Danvers, in a new way. She’s working for the DEO, which is led by Cameron Chase. Kara’s at the DEO to further her main goal and objective—understanding humans.”'' Orlando said regarding the adapted elements from the TV show.

In the new comic book series, Kara uses as her civilian identity the name "Kara Danvers", which originated from the show. Her adoptive parents are also established as Jeremiah and Eliza Danvers and her hometown is National City. Her connection to the D.E.O. is also part of the series, as her parents both work there as agents along with her, though the organization is ran by Cameron Chase instead of Hank Henshaw. Cat Grant and her company, in which Kara becomes an intern, are also included in the series. One major difference from the TV show though is that in the comic book series, Kara is depicted as a sixteen-year old teenager instead of a young adult in her early to mid-twenties.

Some elements from the show, like her civilian name and her adoptive family, were also incorporated in the out-of-continuity limited series, Supergirl: Being Super.
