Arrowverse
The Arrowverse is a shared fictional universe encompassing a series of interconnected American live-action television programs based on DC Comics characters, primarily produced by Greg Berlanti's Berlanti Productions in association with Warner Bros. Television and aired on The CW network.[1] It originated with the debut of Arrow on October 10, 2012, which reimagined Green Arrow (Oliver Queen) as a gritty vigilante returning to Starling City after years stranded on an island.[1] The franchise quickly expanded through spin-offs and crossovers, establishing a multiverse framework that allowed for shared continuity, character appearances across shows, and large-scale events drawing from DC lore.[2] At its core, the Arrowverse includes flagship series such as Arrow (2012–2020, 8 seasons), The Flash (2014–2023, 9 seasons), Supergirl (2015–2021, 6 seasons), DC's Legends of Tomorrow (2016–2022, 7 seasons), Black Lightning (2018–2021, 4 seasons), and Batwoman (2019–2022, 3 seasons).[1] These programs follow heroes like Barry Allen (The Flash), Kara Danvers (Supergirl), and Sara Lance (White Canary) as they combat supervillains, alien threats, and existential crises, often incorporating elements like the Speed Force, metahumans, and time travel.[2] Constantine (2014–2015), originally on NBC, was retroactively integrated into the canon, with its lead John Constantine (Matt Ryan) recurring in later crossovers.[1] Superman & Lois (2021–2024, 4 seasons) initially connected to the universe but was established as part of a rebooted Earth-Prime following the 2019–2020 "Crisis on Infinite Earths" event, diverging from the main continuity.[2] The franchise's hallmark is its annual crossover events, which temporarily unite casts from multiple series for epic, multi-episode arcs inspired by DC Comics storylines.[1] Notable examples include "Flash vs. Arrow" (2014), "Invasion!" (2016, featuring extraterrestrial Dominators), "Crisis on Earth-X" (2017, pitting heroes against Nazi doppelgangers), "Elseworlds" (2018, involving reality swaps and the introduction of Batwoman), and the monumental "Crisis on Infinite Earths" (2019–2020), a five-part saga that merged the Arrowverse with other DC media, including appearances by Brandon Routh as Superman and Kevin Conroy as Bruce Wayne.[2] These events not only boosted viewership but also advanced the overarching narrative, culminating in the multiverse's partial reset during "Crisis," where Oliver Queen's sacrifice reshaped reality.[1] By the end of Superman & Lois in December 2024, the Arrowverse had produced over 800 episodes across its series, pioneering interconnected TV storytelling akin to the Marvel Cinematic Universe but tailored for broadcast television constraints.[3] The Flash's series finale marked the effective end of the primary shared continuity in 2023, with the franchise officially concluding in 2024 and no new series produced since, as DC transitions to a rebooted universe.[4] though spin-off potential and animated extensions like Vixen (2015–2016) persist in the broader DC ecosystem.[2] The franchise's legacy lies in revitalizing lesser-known DC characters for a modern audience, emphasizing themes of heroism, redemption, and ensemble dynamics while navigating production challenges like the COVID-19 pandemic and shifting network priorities.[1]Development
Origins and influences
The Arrowverse originated from the development of the television series Arrow, conceived as a successor to the long-running DC Comics adaptation Smallville. Greg Berlanti, Marc Guggenheim, and Andrew Kreisberg served as co-creators and executive producers, with Berlanti drawing from his experience on Smallville to pitch a grounded take on Green Arrow to Warner Bros. Television in 2011. Their vision emphasized a darker, more realistic tone compared to Smallville's lighter approach, focusing on Oliver Queen's transformation from a playboy to a vigilante after surviving a shipwreck. Key influences on Arrow stemmed from DC Comics' Green Arrow mythos, particularly the character's debut in More Fun Comics #73 in 1941 and his evolution into a socially conscious archer in the 1970s alongside Green Lantern in Dennis O'Neil and Neal Adams' run. The series also drew inspiration from Christopher Nolan's The Dark Knight trilogy, adopting a gritty, noir aesthetic and emphasis on moral complexity in vigilantism, as Berlanti cited Nolan's Batman films as a benchmark for blending superhero action with real-world stakes. Additionally, the flashbacks structure was influenced by the TV series Lost, with Guggenheim noting its use of nonlinear storytelling to reveal the hero's backstory as a narrative device that mirrored their plans for Oliver Queen's island survival tale.[5] Development of the Arrow pilot accelerated in 2012 after The CW greenlit the project in January, with Stephen Amell cast as Oliver Queen in February following auditions that highlighted his physicality and dramatic range. Filming for the pilot episode commenced in March 2012 in Vancouver, British Columbia, under director David Nutter, who incorporated high-stakes action sequences like the opening shipwreck to establish the series' tone. Early production decisions intentionally seeded a shared universe, including Easter eggs in Arrow's first season—such as a newspaper clipping in the pilot referencing a scientist named "Dr. Barry Allen" struck by lightning—to hint at future crossovers without overt commitment. These subtle nods, approved by Berlanti and Guggenheim, laid the groundwork for expanding DC properties on television while adhering to Warner Bros.' guidelines on character rights.Naming and expansion
The term "Arrowverse" was first coined by fans in 2014, coinciding with the premiere of The Flash and its promotional crossover with Arrow, which highlighted the emerging shared universe of DC Comics-based series on The CW.[6] Producers, including executive Marc Guggenheim, officially adopted the term as the franchise grew, using it in interviews and promotions to describe the interconnected narrative by the late 2010s.[6] Executive producer Greg Berlanti envisioned an expansive shared universe from early in Arrow's run, aiming to assemble a television equivalent of the Justice League; this vision materialized with the July 2014 announcement of the Flash vs. Arrow crossover event, confirming the deliberate linkage of multiple series.[6] In November 2014, Berlanti publicly expressed interest in incorporating the CBS series Supergirl—also under his production—into this universe, setting the stage for further growth.[7] Key expansion milestones included Supergirl's relocation from CBS to The CW in May 2016, enabling direct crossovers and full integration into the Arrowverse after its first season aired separately due to network constraints.[8] Similarly, Black Lightning premiered on The CW in January 2018 with an initial intent to operate as a standalone series, avoiding immediate ties to the broader universe to emphasize its unique cultural focus, though it was later folded into the shared continuity during the 2019 Crisis on Infinite Earths event.[9] Coordinating crossovers presented ongoing challenges, such as aligning production schedules across multiple shows filmed primarily in Vancouver. The COVID-19 pandemic exacerbated these issues starting in 2020, halting filming mid-season and resulting in shortened episodes and postponed events, while declining viewership—exemplified by Arrow's finale drawing only 0.3 adults 18-49 rating—contributed to a broader contraction, with series like Supergirl, Black Lightning, Batwoman, and Legends of Tomorrow concluding by 2022 amid reduced budgets and fewer interconnected stories.[10][11]Live-action television series
Arrow (2012–2020)
Arrow is an American superhero television series developed by Greg Berlanti, Marc Guggenheim, and Andrew Kreisberg, based on the DC Comics character Green Arrow created by Mort Weisinger and George Papp.[12] The premise centers on billionaire playboy Oliver Queen, who is presumed dead after a shipwreck and spends five years on a remote island in the North China Sea, undergoing a profound transformation.[13] Upon returning to Starling City (later renamed Star City), he adopts the vigilante persona of the Arrow to wage a one-man war against corruption, targeting individuals from a list of names provided by his late father, Robert Queen, who implicated them in the city's decline.[14] Over the series, Oliver's mission evolves from street-level vigilantism against local criminals and corrupt elites to confronting global threats, including organized crime syndicates, mystical societies, and extraterrestrial invasions, all while balancing his personal life and assembling a team of allies.[15] The show premiered on The CW on October 10, 2012, and concluded after eight seasons on January 28, 2020, comprising 170 episodes.[15] Guggenheim served as showrunner for seasons 1 through 6 and 8, overseeing the narrative direction alongside Berlanti and Kreisberg in the early years, with subsequent contributions from Wendy Mericle and Beth Schwartz.[12] Production emphasized practical stunts and archery sequences, with an initial visual effects budget significantly lower than later Arrowverse entries—estimated at around $1-2 million per episode—allowing for a grounded aesthetic that evolved as the series incorporated more ambitious CGI for larger-scale action and supernatural elements.[16] Filming primarily occurred in Vancouver, British Columbia, with the production adapting to increasing narrative complexity, including flashbacks to Oliver's island ordeal and Hong Kong operations, which added layers to his character development.[17] Season 1 establishes Oliver's return and his systematic takedown of the list's targets, culminating in thwarting "The Undertaking," a plot to destroy the city's Glades district led by Malcolm Merlyn.[18] Season 2 expands on the list's remnants while introducing Slade Wilson (Deathstroke) as a vengeful antagonist from Oliver's past, alongside the debut of the League of Assassins in the episode "League of Assassins," a secretive order of warriors that recruits Sara Lance and later becomes a central antagonistic force under Ra's al Ghul in season 3.[19] Mid-seasons shift toward mystical and organizational threats, such as Damien Darhk's H.I.V.E. cult in season 4 and Prometheus's personal vendetta in season 5, incorporating crossovers like the alien invasion in season 5's "Invasion!" episode.[20] Later seasons, particularly 7 and 8, integrate broader Arrowverse elements, including multiverse-spanning crises that culminate in Oliver's sacrificial role during the "Crisis on Infinite Earths" event, tying his arc to cosmic threats while reflecting on his vigilante legacy.[21] As the foundational series of the Arrowverse shared universe, Arrow introduced key recurring characters such as Felicity Smoak, a brilliant hacker who evolves from IT specialist to integral team member and Oliver's romantic partner, and John Diggle, a former soldier who becomes his first ally and confidant, both of whom appear in spin-offs like The Flash and Legends of Tomorrow.[21] The show's success in blending serialized storytelling with procedural elements paved the way for the expansion of the franchise, establishing crossovers and a cohesive mythology that influenced subsequent DC television productions.[12]The Flash (2014–2023)
The Flash is an American superhero television series that premiered on The CW on October 7, 2014, centering on Barry Allen, a forensic scientist in Central City who gains superhuman speed after being struck by lightning during a malfunction at S.T.A.R. Labs' particle accelerator experiment.[22] The explosion not only imbues Barry with metahuman abilities but also unleashes dark matter across the city, creating other metahumans and supernatural threats that he combats as the vigilante known as The Flash.[23] This premise expands the Arrowverse by introducing sci-fi elements like accelerated particles and alternate dimensions, contrasting the grounded vigilantism of Arrow.[24] Developed for The CW by writers Greg Berlanti, Andrew Kreisberg, and Geoff Johns, the series spanned nine seasons and 184 episodes, concluding on May 24, 2023.[25] Grant Gustin was cast as Barry Allen in September 2013, following his guest appearance in Arrow's second season, bringing a youthful energy to the role that anchored the show's focus on personal growth amid escalating threats.[26] Over its run, production shifted emphasis from initial metahuman pursuits to deeper explorations of the Speed Force—an extradimensional energy source powering speedsters—and time travel mechanics, incorporating nonlinear storytelling and causal paradoxes central to Barry's heroism.[27] The series' key narrative arcs unfold across its seasons, with the first three emphasizing Barry's battles against iconic villains, starting with Eobard Thawne, the Reverse-Flash, who orchestrates the particle accelerator incident to eliminate his future nemesis.[28] Mid-seasons delve into Earth-2, a parallel universe introduced in season two, where Barry encounters alternate versions of his allies and confronts speedster antagonist Zoom, expanding the multiverse framework.[29] Later arcs integrate the "Crisis on Infinite Earths" event, a multiversal cataclysm that reshapes reality, followed by post-Crisis reboots that consolidate the Arrowverse into a unified Earth-Prime, altering character histories and alliances.[30] Innovations in The Flash include the adaptation of vibrational phasing, a Speed Force-derived ability allowing Barry to pass through solid objects by vibrating at specific frequencies, which becomes pivotal in evading traps and accessing hidden realms.[31] The show also pioneers multiverse travel within the Arrowverse, using breaches between Earths to facilitate interdimensional journeys that underpin larger crossover lore and explore themes of identity across realities.[32] These elements, drawn from DC Comics mythology, elevate the series' conceptual depth, making speed not just a power but a conduit for time manipulation and existential threats.[27]Supergirl (2015–2021)
Supergirl is an American superhero television series that follows Kara Zor-El, also known as Kara Danvers and Supergirl, a Kryptonian refugee who arrives on Earth-38 as a teenager and spends over a decade suppressing her superhuman abilities before embracing her role as a protector of National City.[33] Working as a reporter at CatCo Worldwide Media, Kara balances her civilian life with her duties as a hero, collaborating with the Department of Extranormal Operations (DEO), a government agency dedicated to handling alien threats and metahuman activities.[34] The series premiered on CBS on October 26, 2015, developed by Ali Adler, Greg Berlanti, and Andrew Kreisberg, with Melissa Benoist cast as Kara after an extensive audition process in January 2015.[35] The show ran for six seasons and 126 episodes, initially airing its first season of 20 episodes on CBS before moving to The CW in its second season, a relocation announced on May 12, 2016, to better align with the Arrowverse's shared universe on the Warner Bros. network.[36][37] Production emphasized feminist themes, with co-creator Ali Adler highlighting empowerment and the dynamics between strong female characters like Kara and her sister Alex Danvers, portrayed by Chyler Leigh, as central to the narrative.[38] Benoist's portrayal was praised for embodying optimism and resilience, drawing from the character's comic roots while addressing modern issues of identity and self-actualization.[39] Early seasons focus on Kara's emergence as National City's defender against escaped Kryptonian prisoners and other extraterrestrial dangers, with the DEO providing key support under the leadership of J'onn J'onzz, the Martian Manhunter, played by David Harewood.[34] Later arcs expand to global threats, including the Worldkillers in season three—a trio of genetically engineered Kryptonians led by the villainous Reign—challenging Kara's moral code and forcing alliances with figures like Lena Luthor, portrayed by Katie McGrath.[40] Following the "Crisis on Infinite Earths" crossover event, the series incorporates multiverse adjustments in seasons five and six, where Earth-38 merges into a new Earth-Prime, altering character histories and intensifying conflicts with anti-alien sentiment and personal losses for Kara.[41] Distinct from the grittier tones of other Arrowverse entries, Supergirl emphasizes themes of hope and optimism, portraying Kara as a beacon of inspiration amid adversity.[42] It uniquely explores alien refugee narratives, using Kryptonian and other extraterrestrial characters to allegorize immigration and discrimination, particularly in later seasons addressing rising xenophobia in National City.[43] This focus on empathy and integration sets the series apart, reinforcing its message that strength lies in uplifting others rather than isolation.[44]Legends of Tomorrow (2016–2022)
DC's Legends of Tomorrow follows a team of misfit heroes and villains recruited by time traveler Rip Hunter to correct aberrations in the timeline that threaten history, operating from the time ship Waverider.[45] The series emphasizes the team's dysfunctional dynamics as they jump through eras to fix anomalies caused by villains altering events, blending action with comedic elements that set it apart from the more grounded tones of Arrow and The Flash. This ensemble approach allows for character-driven stories focused on redemption and teamwork amid chaotic time-hopping adventures.[46] The show ran for seven seasons and 110 episodes from January 21, 2016, to March 2, 2022, on The CW, produced by Berlanti Productions and Warner Bros. Television.[47] To manage the demands of its large, evolving cast, the production incorporated frequent character rotations, introducing new members while phasing out others to prevent actor burnout and keep narratives fresh.[48] Its humorous, self-aware tone—often embracing absurdity and pop culture parodies—contrasted sharply with the serious vigilante drama of its Arrowverse siblings, allowing for lighter explorations of superhero tropes. Early seasons centered on confronting Vandal Savage, an immortal tyrant creating timeline disruptions in season 1, followed by season 2's battle against the Legion of Doom, who seize the Spear of Destiny to reshape reality into the dystopian "Doomworld."[45] Subsequent arcs introduced magical elements, such as the demon Mallus in season 3, who manipulates historical figures through possessions and totems to break free from imprisonment.[49] The final seasons shifted to multiversal maintenance, with the team addressing "fixed points" in time—unchangeable events—and dealing with an AI enforcer pursuing timeline violations, emphasizing broader cosmic housekeeping.[50] The series significantly contributed to the Arrowverse by spotlighting lesser-known DC characters, such as pyromaniac Mick Rory (Heat Wave), a Flash rogue reimagined as a reluctant hero with a penchant for pulp novels.[51] It also featured Zari Tomaz, a modern take on the obscure 1970s heroine Isis, portraying her as a Muslim-American hacktivist wielding an ancient air totem in a dystopian future.[52] Through its time travel framework, Legends expanded the shared universe's lore by establishing rules like aberrations (deviations creating alternate histories) and the consequences of meddling with fixed events, influencing crossovers and multiverse narratives across the franchise.[53]Black Lightning (2018–2021)
Black Lightning is an American superhero television series that follows Jefferson Pierce, a high school principal and former vigilante known as Black Lightning, who possesses the ability to generate and control electricity. Set in the fictional city of Freeland, the show centers on Pierce's decision to resume his vigilante activities to combat the violent gang known as The 100, which threatens his community and family. The narrative emphasizes Pierce's dual life as an educator dedicated to uplifting Black youth and a hero fighting systemic corruption and street-level crime.[54][55] Developed by Salim Akil for The CW, the series stars Cress Williams as Jefferson Pierce and premiered on January 16, 2018, initially conceived as a standalone production outside the broader shared universe of other DC Comics-based shows on the network. It ran for four seasons, comprising 58 episodes, and concluded on May 24, 2021. Production highlighted authentic representation, with Akil drawing from real-world issues in urban Black communities to craft a grounded story distinct from the more fantastical elements of other superhero series. The show's integration into the larger continuity began in 2019 with references and appearances during the "Crisis on Infinite Earths" crossover event.[56][57][58] The series' story arcs revolve around the discovery of mysterious metahuman pods that grant superpowers, leading to a conspiracy orchestrated by the shadowy A.S.A. (American Security Agency), which experiments on civilians to create enhanced individuals for control. Early seasons focus on the fallout from these pods, including gang exploitation and family endangerment, while later ones escalate to an international conflict with Markovia, a nation pursuing its own metahuman program, culminating in the formation of a resistance group akin to the Outsiders. These plots underscore Pierce's efforts alongside his daughters, Anissa (Thunder) and Jennifer (Lightning), to dismantle oppressive structures.[59][60] Thematically, Black Lightning distinguishes itself through its exploration of social justice, addressing racism, police brutality, and community resilience in ways that reflect contemporary Black experiences, setting it apart from predominantly white-led superhero narratives. At its core is the Pierce family's dynamics, portraying a divorced couple—Jefferson and Lynn—navigating co-parenting amid superhuman threats, which humanizes the genre by prioritizing emotional bonds and cultural identity over spectacle. This focus on Black family unity and empowerment has been praised for providing nuanced representation in mainstream television.[61][62][63]Batwoman (2019–2022)
Batwoman is an American superhero television series developed by Caroline Dries that premiered on The CW on October 6, 2019, and concluded after three seasons on March 2, 2022, consisting of 51 episodes across 20 in the first season, 18 in the second, and 13 in the third. The series centers on Kate Kane, portrayed by Ruby Rose, who assumes the role of vigilante protector in Gotham City following the three-year disappearance of her cousin, Bruce Wayne, and his alter ego, Batman.[64] As Batwoman, Kate employs her military training, wealth from Wayne Enterprises, and determination to combat Gotham's rising crime wave, including threats from corrupt officials and criminal organizations, while grappling with personal traumas from her past.[65] The first season primarily explores Kate's origin as Batwoman, focusing on her complex relationship with her presumed-dead twin sister Beth Kane, who has become the villainous Alice, and Kate's quest to reclaim and adapt the Batwoman suit from Bruce's abandoned Batcave. Production faced a significant change after the first season when Ruby Rose departed the role due to on-set injuries and scheduling conflicts, leading to Javicia Leslie being cast as Ryan Wilder, an original character and engineering genius who discovers the Batsuit in the wreckage of Kate's plane crash and takes up the mantle in the second season.[66] The second season introduces antagonists like Safiyah Sohail and her cult-like group, the Many Arms of Death, while delving into Ryan's backstory as a formerly homeless woman seeking justice for her adoptive mother's murder.[67] In the third and final season, Ryan fully embodies Batwoman, confronting a new suit of villains including Marquis Jet and Poison Ivy, amid ongoing themes of identity and legacy. Following the Arrowverse crossover event "Crisis on Infinite Earths," Gotham City was established as part of the unified Earth-Prime, allowing seamless integration with other series without altering the core premise of Batman's absence.[68] The show emphasizes LGBTQ+ representation, with Kate Kane as the first openly lesbian lead in a live-action superhero television series, highlighting her relationships and identity as central to her character arc.[69] To respect ongoing DC Extended Universe films, the series features no appearances by Batman or Bruce Wayne beyond references to his disappearance, focusing instead on Batwoman's independent role in Gotham's defense.[64]Animated web series
Vixen (2015–2016)
Vixen is an animated web series set in the Arrowverse, centering on Mari McCabe, a young woman orphaned in her native Zambezi and raised in Detroit, who discovers an ancestral totem granting her the ability to channel the powers and abilities of any animal on Earth.[70] As Vixen, Mari uses these spirit animal powers to combat crime and animal-themed threats in her adopted city, drawing on the strength of lions, speed of cheetahs, and senses of eagles to protect the innocent.[71] The series explores themes of identity, heritage, and heroism, with Mari balancing her fashion design career and vigilante life while uncovering the mysteries surrounding her family's totem.[72] Produced by DC Entertainment and Warner Bros. Animation for The CW's digital platform CW Seed, Vixen consists of two seasons, each comprising six short episodes around five to six minutes in length, allowing for a serialized narrative in a bite-sized format.[73] The series was created by Marc Guggenheim and Wendy Mericle, with executive production from Greg Berlanti and Sarah Schechter, and it premiered its first season on August 25, 2015.[74] Megalyn Echikunwoke leads the voice cast as Mari McCabe/Vixen, delivering a portrayal of a resilient, multifaceted hero, supported by Anika Noni Rose as Mari's mother and Sean Patrick Thomas as her father.[75] The production integrates ties to the live-action Arrowverse through guest voice appearances, including Stephen Amell as Oliver Queen/Green Arrow, Grant Gustin as Barry Allen/The Flash, and others like Emily Bett Rickards as Felicity Smoak, enhancing connectivity; this culminated in Echikunwoke reprising the role live-action during Arrow's fourth season.[74] The first season arc revolves around the theft of Mari's totem by a criminal syndicate exploiting its powers for illicit gains, forcing her to reclaim it while evading misunderstandings from Earth-1 heroes like Green Arrow and The Flash, who initially view her as a potential threat.[74] Episodes build Mari's origin, highlighting her internal conflicts and growth as she hones her abilities against localized foes in Detroit, culminating in alliances that affirm her place in the shared universe.[73] Season two, subtitled "Trial by Fire" and renewed in January 2016 before premiering on October 13, 2016, broadens the scope to global villains, introducing Mari's estranged sister Kuasa—who wields a corrupted version of the totem—and escalating conflicts that draw in more Arrowverse characters for support.[76] This expansion emphasizes international stakes, family reconciliation, and the totem's deeper lore, with Mari venturing beyond Detroit to thwart a larger conspiracy.[77] As the Arrowverse's inaugural animated production, Vixen marked a pivotal expansion into web-based animation, experimenting with shorter formats and diverse representation by featuring a Black female lead, while establishing early multiverse links through seamless cameos from Earth-1 elements.[73] Its success in blending origin storytelling with crossover potential laid groundwork for subsequent animated entries, demonstrating the franchise's versatility across media.[78]Freedom Fighters: The Ray (2017–2018)
Freedom Fighters: The Ray is an American animated web series produced by Blue Ribbon Content and Warner Bros. Animation, serving as the second installment in the Arrowverse's lineup of animated productions following Vixen. The series centers on Raymond "Ray" Terrill, a journalist who acquires the ability to manipulate light after exposure to a genetic light substance, leading him to battle the Nazi regime on the alternate Earth-X.[79] [80] Premiering on December 8, 2017, on The CW's streaming platform CW Seed, the show consists of two seasons, each comprising six episodes. It features voice acting by Russell Tovey as the titular hero, with notable contributions from Wentworth Miller voicing Leo Snart, an alternate version of Captain Cold, in the second season. The production was overseen by executive producers Greg Berlanti, Marc Guggenheim, Sarah Schechter, and Kevin Smith, aiming to expand the Arrowverse's multiverse through this dystopian narrative.[81] [82] [83] In the first season, the story focuses on Ray's origin and his journey of self-discovery, including embracing his identity as a gay man, as he is thrust into the resistance against the oppressive New Reich on Earth-X, forming the Freedom Fighters team with allies like an alternate Black Siren and Red Tornado. The narrative explores themes of identity and resistance in a world where the Axis powers emerged victorious in World War II.[84] [85] The second season delves deeper into the team's battles, introducing antagonists like Overgirl, a Nazi version of Supergirl, and incorporating Leo Snart as a key ally and romantic interest for Ray, further developing the interpersonal dynamics and escalating the conflict against the regime. This season builds on the foundation laid in the first, emphasizing team formation and strategic fights.[82] [86] The series plays a crucial role in the Arrowverse by fleshing out the Earth-X storyline, providing backstory for elements featured in the live-action crossover event "Crisis on Earth-X," thus influencing subsequent live-action events with its depiction of alternate realities.[87] ===== END CLEANED SECTION =====Recurring characters
Central heroes
Oliver Queen, portrayed by Stephen Amell, serves as the foundational hero of the Arrowverse, debuting in Arrow as a billionaire playboy shipwrecked on a remote island after the sinking of the Queen's Gambit yacht in 2007. Surviving five years of isolation and hardship, he returns to Starling City (later Star City) transformed into a vigilante known initially as the Hood, targeting corruption with lethal precision inspired by his father's dying wish to right societal wrongs.[88] Over eight seasons, Queen's evolution reflects a shift from ruthless vigilantism to principled heroism; after the death of his friend Tommy Merlyn in season 1, he adopts the moniker "Arrow" and eventually "Green Arrow," embracing a no-kill code while assembling a team to combat escalating threats like the League of Assassins and immortal foes. His arc culminates in the 2019-2020 "Crisis on Infinite Earths" crossover, where he sacrifices himself to defeat the Anti-Monitor, only to be resurrected as the Spectre, a divine spirit of vengeance aiding in the multiverse's rebirth. This transformation solidifies Queen's legacy as the Arrowverse's sacrificial cornerstone, influencing heroes across Earth-Prime.[89][90] Barry Allen, played by Grant Gustin, emerges as the speedster protagonist in The Flash, originating as a Central City Police Department forensic scientist orphaned by his mother's murder and father's wrongful imprisonment. In 2013, struck by lightning during a particle accelerator explosion at S.T.A.R. Labs, Allen gains superhuman speed via the Speed Force, adopting the Flash mantle to protect his city and atone for past losses. His journey involves mastering time travel and alternate timelines, often grappling with predestined tragedies.[91] Allen's personal growth includes two marriages to journalist Iris West-Allen (Candice Patton): a interrupted Earth-X Nazi invasion ceremony in 2017 and a heartfelt renewal post-Crisis, navigating challenges like cryogenic pregnancies and multiversal threats. As a central figure in saving the multiverse, he plays a pivotal role in "Crisis on Infinite Earths," including leading paragonal efforts, traveling to the future for an antimatter weapon, and meeting his DCEU counterpart, while the prophecy of the Flash's sacrifice is fulfilled by Barry Allen of Earth-90.[92] Kara Zor-El, portrayed by Melissa Benoist, anchors Supergirl as a Kryptonian refugee who crash-landed on Earth as a teenager in 1989, her pod delayed by 30 years due to gravitational anomalies. Adopted by the Danvers family, she suppresses her powers while working as assistant to media mogul Cat Grant in National City, until a 2015 plane crash prompts her to embrace her cousin Superman's legacy as Supergirl, fighting alien threats and personal doubts.[93] Kara's evolution from insecure assistant to empowered icon involves balancing her dual identity as Kara Danvers and Supergirl, forging alliances against foes like the Worldkillers and her aunt Astra. In "Crisis on Infinite Earths," she is designated the Paragon of Hope by the Book of Destiny, her unyielding optimism key to rallying survivors and preserving the multiverse, marking her as a beacon of resilience in the Arrowverse.[94] Sara Lance, enacted by Caity Lotz, transitions from Arrow's ill-fated assassin to the time-traveling captain in Legends of Tomorrow. Initially the lover of Oliver Queen, she perishes in the Queen's Gambit wreck but is resurrected via the Lazarus Pit, emerging as the White Canary—a skilled fighter haunted by her violent past in the League of Assassins. Recruited by Rip Hunter in 2016, she leads the ragtag Legends team aboard the Waverider, correcting temporal aberrations with a blend of lethality and empathy.[95] Jefferson Pierce, portrayed by Cress Williams, headlines Black Lightning as Freeland's principal and retired metahuman vigilante who generates electricity. Motivated by protecting his daughters from gang violence, he reactivates as Black Lightning after a decade away, confronting the shadowy A.S.A. organization experimenting on metahumans. His late integration into the Arrowverse occurs during "Crisis on Infinite Earths," where he survives his Earth's destruction by entering a protective pod, emerging as a key defender of the remnants of his destroyed Earth.[96] Kate Kane, played by Ruby Rose in the first season of Batwoman, embodies Gotham's caped crusader after her military academy expulsion and twin sister Beth's presumed death in a car crash. Returning in 2019 following Bruce Wayne's disappearance, Kate dons the Batwoman suit to safeguard her city from chaos, evolving from vengeful heir to strategic leader confronting family traumas and the Wonderland Gang.[97] Succeeding her is Ryan Wilder, portrayed by Javicia Leslie, a brilliant but nomadic engineer who discovers the Batsuit in a plane crash wreckage. Unlike the disciplined Kate, Ryan's "likable, messy" approach infuses Batwoman with goofiness and determination, as she battles Gotham's underworld while uncovering her own heritage, briefly teaming with Kate post-rescue in season 2 before fully claiming the mantle.Key supporting roles
Felicity Smoak serves as a pivotal tech expert originating from Arrow, where she begins as an IT specialist at Queen Consolidated before becoming a core member of Team Arrow, providing crucial technological support through hacking, gadgetry, and strategic analysis that aids Oliver Queen's vigilante efforts.[98] Her expertise extends across the Arrowverse, particularly in crossovers, where she facilitates communication and data analysis between teams, such as during the "Crisis on Infinite Earths" event, helping coordinate multiversal threats by leveraging her skills in cybersecurity and AI development.[99] This bridging role enhances ensemble dynamics by offering non-combat solutions to complex problems, often injecting levity and emotional grounding amid high-stakes alliances.[100] Cisco Ramon, known as Vibe, emerges as a mechanical engineering prodigy on The Flash, inventing key devices like the interdimensional extrapolator that enables breaching between Earths, which proves essential for Team Flash's operations against speedster villains and dimensional incursions.[101] His vibing powers—vibration manipulation for visions and portals—evolve into full breacher capabilities, allowing him to connect with Legends of Tomorrow by aiding time-travel anomalies and even briefly joining the Waverider crew to combat magical threats like Mallus.[102] In ensemble contexts, Cisco's inventive humor and loyalty foster team cohesion, bridging scientific innovation with the supernatural elements of the Legends' roster.[103] Alex Danvers acts as the steadfast adoptive sister to Kara Zor-El on Supergirl, initially as a DEO agent before ascending to director, where she oversees alien containment and defense protocols while providing unwavering familial support that grounds Kara's heroism in human vulnerability.[104] Her protective instincts drive key arcs, including training Kara post-Kryptonian arrival and navigating DEO politics to shield her sister from governmental overreach.[105] Romantically, Alex explores her identity through relationships with Maggie Sawyer, a police detective whose partnership challenges her career loyalties, and later Kelly Olsen, a social worker who deepens her personal growth and integrates into the superhero family dynamic.[106] These elements position Alex as a linchpin in cross-show ensembles, offering tactical leadership and emotional depth during invasions like "Invasion!"[107] Among other key supporters, John Constantine brings unparalleled occult knowledge to the Arrowverse, debuting as a cynical exorcist and demonologist who aids Arrow against supernatural foes before joining Legends of Tomorrow to counter time-altered mystical entities with spells, soul-trapping rituals, and arcane lore.[108] His expertise in the dark arts, honed from teenage dabblings in magic, bridges the gap between street-level vigilantism and cosmic horrors, contributing sardonic wisdom that tempers the Legends' more optimistic heroes.[109] Similarly, Nyssa al Ghul embodies deep ties to the League of Assassins as Ra's al Ghul's daughter, trained from childhood in lethal combat and strategy, initially clashing with Team Arrow over League doctrines before allying to dismantle the organization she once led.[110] Her insider knowledge of assassin networks and moral evolution from enforcer to reformer strengthen ensemble defenses against global threats, as seen in her warnings about splinter factions.[111] Finally, Caitlin Snow grapples with her dual identity as a brilliant bioengineer on The Flash and the cryokinetic Killer Frost, a persona triggered by particle accelerator exposure that manifests aggressive tendencies while retaining fragments of Caitlin's intellect.[112] This internal conflict enriches team interactions, as Caitlin's scientific prowess develops meta-human cures and Frost's raw power assists in battles, ultimately harmonizing into a unified ally that bolsters crossovers with her versatile cryogenic abilities.[113]Crossovers and multiverse
Official crossover events
The Arrowverse's official crossover events represent pivotal multi-series narratives that unite heroes from various shows to confront shared threats, often spanning multiple episodes and introducing new elements to the shared universe. These events began modestly with two-show team-ups and evolved into expansive spectacles involving the core live-action series, emphasizing themes of collaboration, multiversal peril, and character growth. Productionally, they required coordinated scheduling across networks like CBS for Supergirl's early involvement, logistical challenges in filming ensemble scenes, and creative integration of guest stars to heighten stakes.[114][115] The inaugural event, "Flash vs. Arrow," aired in December 2014 as a two-part story across The Flash season 1, episode 8, and Arrow season 3, episode 8. In the premise, Oliver Queen travels to Central City pursuing a criminal arms dealer, leading to an initial clash with Barry Allen over differing vigilante philosophies before they unite against the meta-human Roy Bivolo, who manipulates emotions to incite chaos. This marked the first on-screen team-up between the two flagship heroes, establishing the Arrowverse's interconnected framework and testing the feasibility of cross-show production, including shared sets and actor crossovers without disrupting individual series arcs. Narratively, it introduced shared threats like meta-humans bleeding into Starling City, influencing future storylines by solidifying Team Arrow and Team Flash's alliance.[114][115][116] "Invasion!" in 2016 expanded to a four-part event spanning Supergirl season 2, episode 8; Arrow season 5, episode 8; The Flash season 3, episode 8; and Legends of Tomorrow season 2, episode 8. The plot centers on the alien Dominators invading Earth-1 to abduct humans for experimentation, prompting Barry Allen to recruit Kara Zor-El from Earth-38 for aid, alongside Oliver Queen and the Legends of Tomorrow crew in a temporary Legends of Today team-up. Production challenges included Supergirl's CBS-to-CW transition, requiring Melissa Benoist's travel for filming, and balancing action sequences across three nights. The event's narrative impact highlighted multiversal travel mechanics, with Kara's integration foreshadowing broader Arrowverse expansion, and it emphasized heroic unity against extraterrestrial foes, boosting viewership through high-stakes battles and humor.[117][117] "Crisis on Earth-X," the 2017 four-part crossover, unfolded across Supergirl season 3, episode 8; Arrow season 6, episode 8; The Flash season 4, episode 8; and Legends of Tomorrow season 3, episode 8. The story depicts invaders from the Nazi-dominated Earth-X—led by Dark Arrow (a doppelgänger Oliver) and Overgirl (an evil Kara)—crashing Barry and Iris's wedding to harvest Kara's heart for their dying leader. Filming over two nights posed logistical hurdles, such as coordinating four shows' casts and incorporating wedding elements amid action, while drawing from the 1980s comic Invasion! for inspiration. Its impact included deepening character relationships through personal losses, like Alex Danvers' Earth-X counterpart, and exploring darker alternate realities, which resonated thematically by tying into real-world issues without overt preaching.[92][118][119] The 2018 "Elseworlds" event comprised three episodes: The Flash season 5, episode 9; Arrow season 7, episode 9; and Supergirl season 4, episode 9. Premise-wise, Arkham Asylum doctor John Deegan, empowered by the Monitor, rewrites reality so Barry and Oliver swap identities—Barry as the Green Arrow and Oliver as the Flash—leading them to Gotham City where they encounter Batwoman (Ruby Rose) and fight The Monitor's test. Production involved a rare Sunday premiere for The Flash to align broadcasts, challenges in identity-swap effects, and introducing Batwoman as a series lead-in. Narratively, it innovated with reality-bending stakes, Batwoman's debut expanding the Gotham connection, and subtle nods to Smallville through farm cameos, reinforcing the Arrowverse's self-referential evolution.[120][121][122] "Crisis on Infinite Earths" (2019–2020) was the most ambitious five-part crossover, covering Supergirl season 5, episode 9; Batwoman season 1, episode 9; The Flash season 6, episode 9; Arrow season 8, episode 8; and Legends of Tomorrow season 5, episode 9 (concluding in January 2020). The Anti-Monitor's antimatter wave destroys parallel Earths, forcing heroes—including Oliver, Barry, Kara, and guests like Brandon Routh's Superman and Tom Welling's Clark Kent—to unite at the Vanishing Point and beyond to reboot the multiverse into Earth-Prime. Production spanned months with cameos from DC films (Ezra Miller's Flash) and TV alumni, facing delays from scheduling and the impending Arrow finale; challenges included epic scale battles and emotional arcs like Oliver's sacrifice. Its profound impact rebooted the canon, merging shows into one Earth, elevating stakes with multiverse destruction, and serving as a narrative capstone that influenced subsequent series integrations.[94][123][124] Post-2020 events scaled back due to production shifts and series endings. "Armageddon" in 2021 was a five-episode arc within The Flash season 8, episodes 1–5, where Barry confronts the future-seer Despero's prophecy of his villainous turn, enlisting allies like Kara, Ryan Wilder (Batwoman), and Ray Terrill (The Ray) in a time-altered crisis. This Flash-centric event addressed pandemic filming constraints by focusing on fewer locations and virtual cameos, while narratively exploring Barry's legacy and multiverse echoes from Crisis. In 2022, planned mini-crossovers involving remaining shows like The Flash and Superman & Lois were discussed but largely unrealized amid cast departures and COVID impacts, resulting in smaller character appearances rather than full events. With the conclusion of The Flash in May 2023 and Superman & Lois in October 2024, no further major crossover events have occurred, effectively closing the chapter on the Arrowverse's interconnected live-action era.[125][126]Multiverse structure
The Arrowverse multiverse, prior to the "Crisis on Infinite Earths" event, operated as a collection of parallel universes designated by "Earth" numbers, each vibrating at distinct frequencies that generally prevented casual interaction. Earth-1 functioned as the core reality for the primary live-action series, including "Arrow," "The Flash," and "Legends of Tomorrow," all set in a shared Vancouver-filmed world where heroes like Oliver Queen, Barry Allen, and the Waverider team operated.[127] Earth-2, introduced in the second season of "The Flash," represented a darker parallel realm accessed via vibrational attunement, home to scientist Harrison "Harry" Wells and speedster villain Zoom, where metahuman threats like the particle accelerator explosion had accelerated societal changes.[128] Earth-38 served as the distinct setting for "Supergirl," isolating Kara Zor-El's adventures in National City from Earth-1's events until crossovers bridged the gap.[127] Earth-X depicted an alternate history where Nazis triumphed in World War II, featuring authoritarian versions of familiar heroes as villains in the "Crisis on Earth-X" storyline. Travel between these pre-Crisis Earths relied on matching vibrational frequencies, often achieved by speedsters phasing through the Speed Force or using advanced technology like S.T.A.R. Labs' breaching devices, allowing selective interdimensional movement without merging realities.[129] Timeline alterations, such as those caused by Barry Allen's intervention in his mother's murder during "The Flash" season 3—known as Flashpoint—created branching realities that reshaped events on affected Earths, with the "Legends of Tomorrow" team intervening to mitigate paradoxes and restore stability through time aberration corrections. The "Crisis on Infinite Earths" crossover (2019–2020) fundamentally rebooted this structure, with the Monitor—portrayed by LaMonica Garrett—overseeing the defense against the Anti-Monitor's multiversal destruction, selecting seven Paragons based on virtues like hope (Kara Danvers/Supergirl), love (Barry Allen/The Flash), destiny (Sara Lance/White Canary), courage (Kate Kane/Batwoman), truth (Ryan Choi), honor (J'onn J'onzz), and humanity (Clark Kent/Earth-96 Superman) to preserve existence via the Book of Destiny.[130][127] This event consolidated the primary CW universes—Earth-1, Earth-38, and elements of Earth-X—into a unified Earth-Prime, merging the shows' timelines into a single primary reality while restoring select pre-Crisis worlds like Earth-2 for narrative purposes.[131] Post-Crisis, the multiverse expanded anew with enhanced Speed Force interconnections enabling easier cross-reality travel, while hypertime provided a framework for resolving timeline inconsistencies from time travel, allowing divergent histories to coexist without full paradoxes and supporting ongoing series flexibility.[132] Earth-Prime became the central hub, integrating characters like Jefferson Pierce/Black Lightning and eliminating prior vibrational barriers for seamless hero interactions across former separate Earths.[131]Integration of external series
The Arrowverse has incorporated elements from earlier DC Comics-based live-action television series through actor reprises and narrative ties, effectively linking them to its shared multiverse without fully retrofitting their entire continuities. A prominent example is the 1990–1991 CBS series The Flash, where John Wesley Shipp portrayed Barry Allen; Shipp later debuted in the Arrowverse as Jay Garrick, the Golden Age Flash, in the season 2 premiere of The Flash (2015), wearing a costume reminiscent of his original role and establishing a legacy connection across Earths.[133] This cameo served as an Easter egg honoring the earlier show while positioning Shipp's character as a multiversal variant, though the 1990 series itself remains a separate continuity rather than canon.[134] Similarly, the NBC supernatural series Constantine (2014–2015), starring Matt Ryan as the exorcist John Constantine, was officially integrated starting with a guest appearance in Arrow season 4 (2015), followed by a two-episode arc in DC's Legends of Tomorrow season 3 (2018).[135][136] This revival canonized the occult elements and Ryan's portrayal into the Arrowverse, allowing Constantine to become a series regular on Legends from season 4 onward and influencing storylines involving magic and Hell.[137] The move addressed fan demand after the original series' cancellation and expanded the Arrowverse's supernatural scope.[138] The 2021–2024 CW series Superman & Lois, featuring Tyler Hoechlin as Clark Kent/Superman from his prior Supergirl appearances, was initially positioned on Earth-Prime following the "Crisis on Infinite Earths" event, integrating it into the Arrowverse's primary reality. Hoechlin reprised the role in crossovers like "Elseworlds" (2018) and "Crisis on Infinite Earths" (2019–2020), providing continuity for the character while the series itself emphasized the Kent family's life in Metropolis over four seasons with limited Arrowverse interactions.[139][140] By season 2, subtle narrative shifts created a soft reboot, distancing it from broader crossovers to focus on standalone storytelling, though multiverse allowances preserved loose ties.[141] Debates persist regarding the integration of other DC properties, such as the WB/CW series Smallville (2001–2011), which features Tom Welling's Clark Kent; despite fan theories proposing it as an Earth in the multiverse—bolstered by Welling's powered-down cameo in "Crisis on Infinite Earths" (2019)—producers have maintained its separation to avoid continuity conflicts.[142] Similarly, connections to animated DC shows remain loose and unofficial, with occasional nods like voice actor crossovers or thematic parallels, but no formal canonization beyond the Arrowverse's own web animations.Marketing
Promotional campaigns
The Arrowverse's promotional campaigns initially focused on establishing Arrow as a standalone series while laying groundwork for a shared universe, with key efforts centered on San Diego Comic-Con panels in 2013 and 2014. At the 2013 Comic-Con panel, producers unveiled a teaser reel for Arrow's second season, highlighting new cast additions like Summer Glau as Isabel Rochev and advanced tech for Oliver Queen, which emphasized the show's evolving narrative scope and attracted early fan engagement through exclusive footage.[143] The following year's panel built on this by announcing The Flash as a spin-off, explicitly teasing the interconnected DC universe with cross-show cameos and shared mythology, marking a pivotal moment in branding the franchise as an expansive shared world. A signature element of these early promotions was Arrow's recurring tagline, "You have failed this city," delivered by Oliver Queen as a condemnation of corruption, which was integrated into trailers, posters, and merchandise to encapsulate the vigilante's moral crusade and became synonymous with the series' gritty tone. Crossover events drove significant hype through targeted media blitzes, particularly annual trailers and social media integrations. For the 2016 "Invasion!" event, The CW released extended trailers showcasing the alliance of Arrow, The Flash, Supergirl, and Legends of Tomorrow against the alien Dominators, with promotional spots emphasizing high-stakes team-ups and alien abduction themes to build anticipation across networks.[144] These efforts were amplified by social media countdowns, fan contests, and behind-the-scenes videos shared on platforms like Twitter and Instagram, fostering viral engagement and positioning the crossover as a must-watch spectacle. Similar strategies were employed for subsequent events, such as the "Crisis on Infinite Earths" in 2019, where teaser trailers highlighted multiverse threats and hero sacrifices to sustain franchise momentum.[145] Following the 2020 launch of HBO Max (rebranded as Max in 2023), promotional campaigns shifted toward digital streaming integration, with ads promoting the platform's acquisition of Arrowverse content like full seasons of Supergirl and Arrow to attract cord-cutters.[146] Character posters played a prominent role in these efforts, notably for "Crisis on Infinite Earths," featuring 18 key heroes including Green Arrow, The Flash, and Supergirl in dramatic group compositions distributed via online banners, social media, and print media to underscore the event's scale and draw in lapsed viewers.[147] Post-2020, the Arrowverse encountered promotional challenges amid declining viewership and production disruptions from the COVID-19 pandemic, resulting in reduced crossover-focused marketing and a pivot to individual show campaigns. Efforts emphasized standalone narratives for series like The Flash and Superman & Lois through targeted trailers and social pushes, reflecting a strategic contraction to sustain core audiences amid franchise fatigue.[148]Tie-in events
The Arrowverse franchise engaged fans through interactive activations at major conventions, particularly San Diego Comic-Con (SDCC), where promotional booths and reveals heightened anticipation for crossover events. In 2016, Warner Bros. Television set up displays featuring production costumes and props from The Flash, Arrow, and Supergirl to promote the "Invasion!" crossover, including alien-themed elements inspired by the Dominators storyline to immerse attendees in the narrative.[149] By 2019, SDCC panels and booths spotlighted costume reveals for the "Crisis on Infinite Earths" event, showcasing updated suits for characters like Green Arrow, Black Canary, and The Flash, which were designed to align with the multiverse-spanning plot and generated significant buzz among attendees.[150] Merchandise tie-ins expanded fan interaction beyond the screen, with official products capturing key characters and themes from the Arrowverse series. Mattel produced action figures under the DC Multiverse line, including detailed 6-inch figures of Green Arrow from Arrow and Barry Allen/The Flash, complete with accessories like bows and lightning effects to recreate iconic scenes. Apparel collaborations with Hot Topic offered themed clothing such as graphic tees featuring Oliver Queen and Felicity Smoak's "Olicity" dynamic, as well as hoodies with the Arrow hood emblem, appealing to cosplayers and casual fans.[151] Funko further popularized collectibles with Pop! Vinyl figures of Supergirl and The Flash, stylized in their TV costumes from crossovers like "Invasion!", which became staples at retail outlets and conventions.[152] Live events fostered direct connections between cast members and audiences, evolving to virtual formats amid the COVID-19 pandemic. During the 2020 pandemic, these shifted to virtual panels, such as the Wizard World Virtual Experiences featuring Arrow cast members Katie Cassidy and Juliana Harkavy, and the expansive DC FanDome event, which hosted Arrowverse-specific sessions with producers and stars to unveil season trailers while adhering to health guidelines.[153] Prior to the 2020 merger with HBO Max, the DC Universe streaming app served as a hub for exclusive Arrowverse-related expansions, offering early access to promotional content like extended clips, cast interviews, and digital comics tying into series events such as "Crisis on Infinite Earths," enhancing subscriber engagement before the broader integration of DC properties.[154]Reception
Viewership metrics
The Arrowverse franchise achieved significant viewership peaks in its early years, particularly with the debut seasons of its flagship series. Arrow's first season in 2012-2013 averaged approximately 4.1 million total viewers per episode in live-plus-same-day Nielsen ratings, marking a strong launch for The CW's superhero programming slate.[155] The Flash's series premiere on October 7, 2014, drew 6.1 million viewers in Live+3 measurements, establishing it as The CW's most-watched series debut at the time and underscoring the growing appetite for interconnected DC adaptations.[156] Following these highs, viewership across the Arrowverse experienced notable declines after 2018, influenced by increased competition from streaming platforms that fragmented audiences and shifted viewing habits away from traditional linear television. Supergirl, after moving to The CW for its second season in 2016, averaged around 1.3 million total viewers per episode across its subsequent runs through season 6, reflecting a steady erosion compared to its CBS debut but still contributing to the franchise's core metrics.[157] This downward trend affected multiple series, with factors like the rise of services such as Netflix and Disney+ drawing younger demographics to on-demand content, resulting in series lows for shows like The Flash and Legends of Tomorrow by 2020-2021.[158] Crossover events provided temporary boosts to mitigate these declines, as seen with the 2019-2020 "Crisis on Infinite Earths" storyline, where individual parts averaged 1.5 to 2 million total viewers per episode in live-plus-same-day ratings. For instance, the Supergirl opener drew 1.67 million viewers, while the subsequent Batwoman and The Flash installments reached 1.69 million and 1.73 million, respectively, highlighting the draw of multiverse-spanning narratives in sustaining engagement.[159][160][161] In the streaming era post-2020, the franchise transitioned to platforms like HBO Max (now Max), where episodes became available for on-demand viewing shortly after broadcast, contributing to sustained interest despite linear declines. As of late 2025, licensing changes led to Arrow and other series departing Netflix US on December 18, 2025, complicating binge-watching despite continued availability on Max.[162] By the end of Superman & Lois in 2024, the Arrowverse had produced over 800 episodes across 10 series and 46 seasons, with streaming data indicating robust replay value—such as The Flash accumulating 311 million viewing hours on Netflix alone in the first half of 2023—demonstrating the shift toward digital consumption.[3][163]| Key Viewership Milestones | Series/Event | Viewers (Millions) | Metric/Source |
