Arrowverse

In August 2015, in a video about the production of Vixen's first season, Guggenheim referred to the series' shared universe as the "Arrowverse".[61] Kreisberg confirmed that this was the name the producers used for it.[62] The universe has also been referred to by the media as the "Flarrowverse", "Berlanti-verse" and "DC TV-verse".[63][64][65]

In September 2020, The CW released a trailer for the various series that would be airing on the network in 2021, which featured the name "The CWverse" in it. Many outlets felt the change was due to Arrow having ended and the character no longer a part of the shared universe.[66][67][68] However, Matt Webb Mitovich of TVLine felt that with the inclusion of Stargirl in the trailer, which exists on a parallel earth to the Arrowverse, the name was perhaps a way to discuss all of the superhero series airing on network at the time. Mitovich also pointed out the term had been used a year prior in a similar trailer, which had featured the Arrowverse series plus Black Lightning, which was not part of the universe at that time.[67] Jake Abbate of SuperHeroHype also referred to the name as encompassing the "programming block" of superhero shows on the network.[68] Daniel Gillespie from Screen Rant felt if this was The CW's attempt to change the Arrowverse's name, that fans and the media would not "suddenly start" using the name, and if The CW kept using the term, could "lead to a situation where the universe is called one thing officially, but another entirely by the majority of people who watch it".[66]

• The number in parentheses next to the episode title indicates which part of the crossover it is, if not clear otherwise.

Yearly crossover events in the Arrowverse have occurred since the 2013–14 television season, when Barry Allen was introduced in the eighth episode of Arrow's second season ahead of the debut of The Flash. The next year, the eighth episodes of the third season of Arrow and the first season of The Flash formed a two-part event known as "Flash vs. Arrow". In January 2015, The CW president Mark Pedowitz said that there would be an Arrowverse crossover every season.[213] In the 2015–16 television season, a two-part event, "Heroes Join Forces" between the eighth episodes of the fourth season of Arrow and the second season of The Flash was used to set up a new team-up series, Legends of Tomorrow.[214] For the 2016–17 television season, the "Invasion!" crossover included The Flash, Arrow, and Legends of Tomorrow, with the event beginning at the end of Supergirl.[215][31][200] A true four-part crossover occurred in the 2017–18 television season with "Crisis on Earth-X", which also tied into the animated web series, Freedom Fighters: The Ray, and featured characters and concepts from that series.[202] The 2018–19 crossover, "Elseworlds",[216] included Supergirl, The Flash, and Arrow and saw the introduction of Batwoman ahead of her debut in her own series.[37] At the end of "Elseworlds", it was revealed that the 2019–20 television season crossover would be "Crisis on Infinite Earths",[39] a five-part crossover with episodes of Supergirl, Batwoman, The Flash, Arrow, and Legends of Tomorrow.[217]

Additional crossovers include "Worlds Finest", an episode which sees Barry Allen travel to Supergirl's Earth for the first time,[218] and "Duet", a musical crossover with The Flash and Supergirl.[123]

By November 2019, Guggenheim, Berlanti, and Pedowitz had discussed what the 2020 crossover would entail,[219] with Guggenheim revealing in January 2020, that a general idea had been approved by Pedowitz and Berlanti.[220] Guggenheim confirmed they had "no intention of trying something [as] ambitious" as the previous year's "Crisis on Infinite Earths", hoping "to really go back to the basics".[219] He felt a crossover like "Crisis on Infinite Earths" was something "you’ve got to build to" and the goal of the next crossover was to "return to the roots" of the Arrowverse crossovers.[220] In May 2020, Pedowitz revealed the crossover would be two hours, occurring on episodes of Batwoman and Superman & Lois, airing in Q1/Q2 of 2021. Pedowitz added that the event would also see many characters from the other Arrowverse series appear.[221][222] Batwoman showrunner Caroline Dries was excited to integrate more of the Batwoman characters in this crossover after she "was really protective of them in "Crisis" because it was like blowing open a whole genre world to our characters, but now people are a little bit more integrated" to the larger Arrowverse.[223] In August 2020, Berlanti reiterated that "aspirations aren't quite as large" for the crossover, particularly with the COVID-19 pandemic necessitating additional safety precautions and guidelines for filming.[224] However, by January 2021, the crossover was no longer moving forward because of the pandemic, with Dries explaining they could not have the crews of each series interact for fear of COVID-19 exposure.[225]

In October 2014, Johns explained that DC's approach to their films and television series would be different from Marvel Studios' cinematic universe, stating that their film universe and TV universes would be kept separate within a multiverse to allow "everyone to make the best possible product, to tell the best story, to do the best world."[226] The second season of The Flash began to explore this concept of the multiverse, by introducing Earth-2, which features doppelgängers of the inhabitants of Earth-1.[227] Supergirl was confirmed as an alternate universe, later designated Earth-38,[30] with The Flash crossover episode "Worlds Finest" (2016).[228] Freedom Fighters: The Ray is set on Earth-X.[115]

The 2019 crossover event "Crisis on Infinite Earths", inspired by the comic of the same name, destroyed all of the universes within the Arrowverse multiverse, both on- and off-screen.[229] At the time, the highest-numbered universe to be referenced was Earth-898,[230] though the multiverse contained an infinite number of universes. The end of "Crisis on Infinite Earths" saw the creation of a new multiverse, most notably the new Earth-Prime, a world featuring inhabitants from the pre-Crisis Earth-1, Earth-38, and Black Lightning's Earth, combining all of the CW series at the time and moving forward with all of them on one fictional earth. Six additional Earths within this new multiverse were revealed in the crossover.[54]

Ezra Miller's cameo as Barry Allen from the DC Extended Universe in "Crisis on Infinite Earths" opened up more possibilities for crossovers between the DC films and Arrowverse. DC Films president Walter Hamada revealed prior to "Crisis", DC had been structured in a way that the television division had to clear the use of characters with the film division. Now, the company could "really lean into this idea of [the multiverse] and acknowledge the fact there can be a Flash on TV and one in the movies, and you don't have to pick one or the other, and they both exist in this multiverse."[231] Berlanti agreed, feeling that "moving forward, there’s more opportunity to do more things like this".[232]

In The Flash (2014 TV series) episode "Welcome to Earth-2" (2016), glimpses of the multiverse are seen, including an image of John Wesley Shipp as the Flash from the 1990 television series, implying that the series exists on an alternate Earth within the Arrowverse multiverse;[233][234] Shipp reprised his role as Barry Allen / The Flash from the 1990 series in the annual crossover events "Elseworlds" (2018),[235] and "Crisis on Infinite Earths" (2019). His native universe was designated Earth-90 in the pre-Crisis Multiverse.[236]

By May 2015, Amell had had discussions with DC Entertainment about portraying Queen on NBC's Constantine, starring Matt Ryan; saying, "The reason that I was going to guest star on Constantine...was [Constantine's] an expert when it comes to the Lazarus Pit, which is now something that is a part of and will continue to be a part of Arrow." Amell stated that, even though Constantine was not renewed for a second season, a crossover "was and is still on the table".[237] Guggenheim revealed a desire to integrate John Constantine into the Arrowverse, saying, "A lot of the pieces are in place, except for that one final piece, which is what's the fate of Constantine? That's the tricky thing. But it comes up in the writers' room constantly—we have a number of ideas, one idea that's particularly exciting to me. We're in a little bit of a wait-and-see mode".[238] In July 2015, Mericle added on the subject, "It's something we've been talking to DC about and it's just a question of some political things, but also [Ryan]'s schedule."[239]

In August 2015, it was confirmed that Ryan would appear in Arrow's fourth-season episode "Haunted" for a "one-time-only-deal". Guggenheim said, "This is something the fans were clamoring for," praising DC for being so "magnanimous and generous in giving us this one-time dispensation." Due to Arrow and Constantine sharing the same studio, the producers of Arrow were able to use Ryan's original outfits: "The trench coat, the tie, the shirt...the whole wardrobe is being taken out for [sic] storage and shipped up to Vancouver [where Arrow shoots]." John Badham, a director on Constantine, directed the episode that Constantine appears in.[240] Mericle confirmed that this version of Constantine would be the same character that had appeared in Constantine.[119] On filming the episode, Guggenheim referred to it as "a Constantine/Arrow crossover" and felt that "we got the chance to extend Matt Ryan's run as Constantine by at least one more hour of television. I think you'll see he fits very neatly into our universe. It never feels forced".[241]

In July 2017, Guggenheim indicated that "really good conversations" had taken place with Ryan to appear again in the Arrowverse,[242] and in October 2017, it was revealed that Ryan would appear in two episodes of the third season of Legends of Tomorrow, "Beebo the God of War" and "Daddy Darhkest", with the appearance taking place chronologically after "Haunted", revisiting the setting of Arrow's fourth season and the events following that season's final episode. Klemmer described the tone of the episodes as "The Exorcist meets One Flew Over the Cuckoo's Nest".[120] Ryan was made a series regular for the fourth season of Legends of Tomorrow.[243]

Jesse Schedeen of IGN felt in October 2018 that none of the character's Arrowverse appearances thus far "really directly reference the events of the Constantine series, leaving it up in the air as to whether this John Constantine is the same character from that series or if Ryan is merely playing a different, very similar version of his character."[244] In November 2018, Ryan spoke to the relationship between the character seen in the NBC series and the one seen on Legends of Tomorrow and in the Arrowverse. He said the two were the same character with "the same DNA", and likened each appearance to that of different comic book writers and artists working with the character: "He has the same outline, but he looks different. The hair is slightly different. He has a slightly different cadence sometimes. Different artists and different writers write him in different ways." Ryan also noted that while the fourth season of Legends of Tomorrow mentions the Astra storyline from the NBC series, it would not explore the Brujeria storyline, though Constantine "still carries that baggage around with him".[245]

The 2019 crossover event "Crisis on Infinite Earths" incorporated several DC Entertainment properties into the Arrowverse multiverse, including those that had already been established in previous series and crossovers. The new properties that appeared in "Crisis on Infinite Earths" included:

After the first Arrow/Flash crossover, Brian Lowry of Variety talked about the spin-off series and the crossover, applauding the producers for replicating the success of Arrow but with "a lighter tone" and "a hero with genuine super powers" in The Flash, and calling the crossover an appropriate moment for everyone concerned to take a short but well-deserved victory lap." Lowry also said that the crossover "does a nifty job of bringing the two series together, although probably not in a manner likely to boost the shared audience between them much more than already exists."[361] Meredith Borders at Birth.Movies.Death. called the crossover episodes "fun" and said positively that "too much happened that was unrelated to one show or the other – and that's a good thing. While the crossover episodes were definitely open to new viewers of either The Flash or Arrow (or both, presumably), with each episode wrapped up tidily by the end of its hour, plenty of show-specific plot stuff was advanced without spelling it out for newbies. New viewers to either show could follow along and have a good time, but veteran viewers were rewarded with major storyline motion."[362]

Following the release of the first trailer for Supergirl, Paul Tassi wrote for Forbes about why he felt that series should be kept separate from the Arrowverse: He called the moment in the Arrow third-season finale where Barry Allen appears briefly, but abruptly leaves since "Arrow needs to let its own characters solve its problems", a "weird moment" that shows "the cracks [that] form when it's just two shows that have to work together on the regular." Tassi then noted the further complications of adding Supergirl, saying, "The more shows you have, the more heroes you introduce, the harder it is to keep explaining away why they're not constantly around to help each other. Supergirl already has that problem built-in with Superman, who it seems will not be a regular fixture on the show, and I'm sure there will be many excuses as to why he's too busy to help Supergirl fight her latest battle. Add in Arrow, The Flash and Legends of Tomorrow mythology, and it's probably too much to juggle....I think Supergirl deserves to launch without Arrow and The Flash on its shoulders, and be allowed to find itself before being assimilated into an existing universe."[363]

With the premiere of Legends of Tomorrow, ScreenRant's Alice Walker discussed how the series "has hurt Arrow and The Flash", noting that the latter required minimal setup when it was spun-off from the former and had an element of mystery surrounding its quality with "a "wait and see" attitude" from audiences, while Legends was instead met with much excitement long before its release leading to each piece of news concerning it being "publicized and met with fanfare – to the detriment of the other shows involved." Walker felt that audiences knowing which characters would appear in Legends, and how, took "the thrill out of the story" of the other series as such information spoiled some of their upcoming plot twists, including the resurrection of Sara Lance or the fact that Ray Palmer "could never really pose a threat to Oliver [Queen] and Felicity [Smoak]'s relationship, or run Palmer Technologies long term, since it was widely known that he would be a huge part of Legends." Additionally, the annual Arrow/The Flash crossover suffered from also trying to set up Legends, which was "too much to ask from the already crowded storylines and ended up feeling like an exercise in synchronicity, with producers planting more seeds than they could reap. The crossover event was no longer a fun way to contrast the two shows; it now had to serve the much larger purpose of setting up an entirely new world." Walker stated that the premiere of Legends "means that Arrow and The Flash can finally stop dedicating so much time and plot to laying the groundwork for the spin-off, and start focusing on the fundamentals of their own shows again."[364]

After the "Elseworlds" crossover teased the comic Crisis on Infinite Earths would be adapted in the 2019 crossover, Mike Cecchini of Den of Geek stated, "The Arrowverse is becoming the most intricate, risky live action superhero universe in history. Yes, it's at least as big and crazy (perhaps even moreso in some ways) than the Marvel Cinematic Universe, and we had best enjoy this while we have it, because it's unlikely we'll ever see this much crazy DC Comics love on screen in one place at one time ever again."[365]

On February 23, 2016, Titan Books released Arrow: Vengeance, a tie-in novel by Oscar Balderrama and Lauren Certo, which is set before and during Arrow's second season, which details the origins of Slade Wilson, Isabel Rochev, and Sebastian Blood, and how they would all eventually meet and collaborate with each other to battle Oliver Queen / The Arrow as seen in the TV series. On November 29, 2016, Titan released The Flash: The Haunting of Barry Allen, a tie-in novel by Susan and Clay Griffith, which is set during The Flash's second season and Arrow's fourth season, which detailed that after he closed the temporal anomaly that nearly destroyed Central City, Barry an older version of himself, beaten, injured, and batter, but before he can speak, his doppelganger disappears. Barry then starts experiencing glitches in his powers, moments that leave him immobile and ghostly during missions. When a group of his worst villains, including Pied Piper, Weather Wizard, and Peek-a-Boo, decide to launch an assault on him, so Barry decides to seek help from his most trusted ally, Oliver Queen / Green Arrow. The story continues in Arrow: A Generation of Vipers, by Susan and Clay Griffith, which was released by Titan on March 28, 2017, which detailed Team Flash and Team Arrow working together to eliminate the bizarre energy that threatens to kill the Flash. When their quest leads them to Markovia, they must get past an army of mercenaries and assassins to face the mysterious Count Wallenstein.

A fourth novel entitled Arrow: Fatal Legacies was released in January 2018. It is co-authored by Arrow executive producer Marc Guggenheim and James R. Tuck, and is set between the fifth-season finale and sixth-season premiere of Arrow.[372] A fifth novel, following The Flash villain Weather Wizard in his attempts at revenge, was released in May 2018. Written by Richard A. Knaak, the novel is titled The Flash: Climate Changeling.[373]

In May 2017, it was announced that Abrams Books would be releasing two trilogies of middle-grade novels for The Flash and Supergirl, written by Barry Lyga and Jo Whittemore, respectively.[374] The first of these novels, The Flash: Hocus Pocus, was released on October 3, 2017. The novel takes place in an alternate timeline where the show's "Flashpoint" event never occurred, and The Flash must fight a villain known as Hocus Pocus who can control the minds and actions of people.[375] A sequel, The Flash: Johnny Quick was released on April 3, 2018,[376] as well as a third novel titled The Flash: The Tornado Twins released on October 2, 2018.[377]

The second of these trilogies began in November 2017, with Supergirl: Age of Atlantis. The novel features Supergirl dealing with a surge of new powered people in National City, as well as a mysterious humanoid sea creature captured by the DEO who is seemingly attracted by the new superpowered people.[378] A sequel, Supergirl: Curse of the Ancients, was released on May 1, 2018,[379] with a third novel, titled Supergirl: Master of Illusion, released on January 8, 2019.[380]

In July 2017, a third trilogy titled Crossover Crisis was announced, focusing on crossovers between characters within the universe on this alternate earth. The series is again penned by Barry Lyga.[381] The first novel, The Flash: Green Arrow's Perfect Shot, was released on August 13, 2019[382] with the second The Flash: Supergirl's Sacrifice released on May 26, 2020.[383] The final novel in the series, The Flash: Legends of Forever, will be published on March 23, 2021.[384]

The first guidebook to be released was Arrow: Heroes and Villains by Nick Aires and published by Titan Books, released in February 2015.[385] Described as "a companion" to the series, the book features sections on the various characters of the series, along with descriptions, backgrounds, comic book origins, and "where they stand as of the end of the second season of 'Arrow.'"[386]

A follow up to Heroes and Villains by the same author and publisher, titled Arrow: Oliver Queen's Dossier, was released in October 2016, during the series' fifth season. The book is presented as information collected by the Green Arrow and Felicity Smoak over the course of his four years of activity. Included in the book are "handwritten notes" and "police reports" regarding the Green Arrow and those he targets.[387]

In May 2018, Titan Books and Aires released a guidebook similar to Oliver Queen's Dossier, but for its sister series, The Flash, from the perspective of Cisco Ramon. S.T.A.R. Labs: Cisco Ramon's Journal features "his confidential journal entries, covering everything from his tech designs, the villains and other heroes the team encounter, the team's personal challenges and his own Vibe abilities prior to Flashpoint."[388]

A second guidebook for The Flash was released in November 2018, this time published by Abrams Books. The Secret Files of Barry Allen: The Ultimate Guide to the Hit TV Show features the Flash's "top-secret notes", as well as "classified S.T.A.R. Labs dossiers on everyone in Central City", an episode guide on the first four seasons of the series, and details on the life of the Flash "in Barry's own words."[389]

A similar guidebook for Supergirl was released in March 2019 from the same publisher. Supergirl: The Secret Files of Kara Danvers: The Ultimate Guide to the Hit TV Show features "detailed profiles on characters and super powers, a heroes and villains gallery, episode guide, and more" from the first three seasons of the series.[390]

On November 6, 2013, a six-episode series of shorts, titled Blood Rush, premiered alongside the broadcast of Arrow, as well as online. The series, which was presented by Bose, and features product placement for Bose products, was shot on location in Vancouver, similarly to the main show. The miniseries features Emily Bett Rickards, Colton Haynes and Paul Blackthorne reprising their roles of Felicity Smoak, Roy Harper and Quentin Lance, respectively. The episodes set during the course of the second season of the television series, show Roy coming to Queen Consolidated to have a meeting with Oliver. As he is out, Felicity tells Roy to go wait in the lobby. As Roy leaves, Officer Lance calls Felicity, telling her that the blood sample the Starling City police found on the vigilante, which Felicity destroyed, has resurfaced. Felicity then calls Roy, using Oliver's voice encoder, asking him to break into the lab to retrieve the sample. Felicity guides Roy through the lab, where he is able to recover the sample. As Roy is leaving, doctors enter the room, seemingly trapping him. He notifies Felicity, who then hacks into the building's PA system, and issues an evacuation notice, giving Roy a chance to escape. Roy gets out of the room before it enters into lock down, and is able to avoid two guards with the help of Felicity and exit the lab. Roy returns to Queen Consolidated, and Felicity offers to mail the acquired sample for Roy as he goes in to meet with Oliver.[391]

On April 19, 2016, a four-episode series of shorts, titled Chronicles of Cisco, premiered on AT&T. The series features Valdes and Britne Oldford reprising their roles as Cisco Ramon and Peek-a-Boo respectively. Set in the second season of the television series, the series sees Cisco attempting to make the Flash suit bulletproof and body-odor proof. While working on these, he receives a late-night Meta-Human Alert within S.T.A.R. Labs, and learns that Peek-a-Boo triggered the alert. She has come to S.T.A.R. Labs to make Cisco create a weapon for her, as he did for Golden Glider, Captain Cold, and Heat Wave. When he does not cooperate, she shoots him. Cisco survives being shot, realizing that the orange soda he spilled on his shirt was the missing catalyst to his bulletproof formula. Cisco tries to bring Peek-a-Boo back to the pipeline, but she locks him in the cell instead. Cisco is then seen being woken up due to a call from Barry. He believes he dreamt the whole experience, until he finds the bullet that shot him on the ground.[392]

On November 14, 2017, a three-episode series of shorts, known as "Stretched Scenes", premiered. The series, presented by Microsoft Surface, features Hartley Sawyer, Danielle Panabaker, and Candice Patton as Ralph Dibny, Cailtin Snow, and Iris West respectively. Set during the show's fourth season, it shows Dibny as he continually bothers Cailtin and Iris for their help, or for attention. The shorts premiered online as well as during the commercial breaks of the episodes "When Harry Met Harry...", "Therefore I Am", and "Don't Run".[393][394][395]

Audio studio Serial Box is currently developing an audio series based on the Arrowverse, titled The Flash: Rogues. The series will feature Lex Luthor altering the timeline in order to turn The Flash, Green Arrow, White Canary, and Supergirl evil, while their friends attempt to fix the timeline. The series currently has eight episodes planned.[396][397]
