Dinah Laurel Lance / Black Siren / Black Canary
"I'm not the old Laurel. I'm me. Everyone has good and bad inside of them and you can't put people in one box or the other, ever."

Species: Enhanced human

Known Alias: Black Canary, Black Siren, 小雀仔 (Siu Jerk Jai, Cantonese for "Little Bird")

Affiliations: Zoom's Gang, Prometheus' Team, Helix, Ricardo Diaz's Gang, Team Arrow


Played By: Katie Cassidy

Appearances: The Flash | Arrow

The Earth-2 counterpart of the late Team Arrow member and Star(ling) City ADA Laurel Lance, known as the superhero Black Canary. A metahuman who can produce high frequency sonic waves through shouting, she's originally introduced as one of Zoom's most powerful allies, whom he brought to the main universe from Earth-2 to wreck havoc on Earth-1 Central City and soon finds herself entangled with Team Flash. After her defeat, she's incarcerated at the pipeline on S.T.A.R. Labs for some time before getting rescued by Simon Morrison aka Prometheus in order to psychologically break Oliver Queen. After her attempt to ally with Team Arrow fails, she ultimately sided with Prometheus for good. After Prometheus' defeat, she finds herself fighting against Team Arrow several times while working with their succeeding enemies Cayden James and Ricardo Diaz.


Circumstances in between ultimately led her into having to impersonate her late Earth-1 counterpart and live her life.

However, her encounters with her late Earth-1 counterpart's father, whom himself is the Earth-1 counterpart of her own late father, gradually changes her for the better, which she solidifies after his death at Ricardo Diaz's hands.

To fully atone for her sins, she decided to become the Black Canary of her home universe.

    open/close all folders 

  • 13 Is Unlucky: Her father died on her thirteenth birthday. The event is heavily implied to be the very first catalyst for her descent to villainy.
  • Adaptation Dye-Job: In the DCAU, she's blonde. Here, she's brunette, but she eventually dyes it blonde when she impersonates Earth-1 Laurel and later decides to keep it.
  • Adaptational Badass: The Black Siren in the DCAU mostly serves as The Chick. Here, she does not hold back in kicking ass and even has the canonical superpower of the Black Canary.
  • Adaptational Modesty: While her costume is closer to the Black Canary's comics outfit compared to Laurel's, it still covers a lot. And then she inherits Laurel's outfit.
  • Adaptational Villainy: In the DCAU, she's a member of the Justice Guild of America in an Alternate Universe. In this show, she's another evil metahuman who works for Zoom, then goes on to work for the likes of Prometheus and Cayden James. This is eventually subverted when she reforms.
  • Adaptation Name Change: Goes both ways. She goes by "Black Siren" instead of "Black Canary", but the Black Siren's real identity is Donna Nance. However, Nance is actually the DCAU's version of Dinah Drake-Lance.
  • Adorkable: In "The Demon", she stumbles over an attempt to ask Felicity to join her for a slice of pizza, and quickly (and unconvincingly) backtracks when Felicity asks if that was an attempt to ask her out on a friend-date.
  • Aloof Ally: When working with Team Arrow after her Heel–Face Turn, she never misses a chance snarking at them or with them.
  • Aloof Dark-Haired Girl: She has dark brown hair (at least initially) and is very snarky and sociopathic.
  • Ambiguously Bi: In "Reversal", she goes on a murder spree and seemingly seduces both her male and female victims.
  • And Starring: Is credited with "Special Guest Star" citations, and after being made a regular for Season Six of Arrow, Katie Cassidy gets a "With" citation, along with Paul Blackthorne.
  • Antagonistic Offspring: To Quentin Lance. Despite being told numerous times she's not his Laurel, she is his daughter as far as he's concern. Plus, she wants to ruin his life for leaving her for dead on the island. Subverted as Season Six goes on; she gets fonder of him with time, and is ultimately convinced to pull a full Heel–Face Turn after his death.
  • Anti-Hero Substitute: After her Heel–Face Turn, she goes from being the late Laurel's Evil Doppelgänger to a Reformed, but Not Tamed Nominal Hero. Also counts as a meta example, as she is Katie Cassidy's second major Arrowverse character but only Darker and Edgier.
  • Arch-Enemy:
    • Quickly establishes herself as for Dinah Drake, whom she hates for "replacing" her not only on Team Arrow, but as Quentin's favorite. Cemented when she kills Vincent Sobel while Dinah watched helplessly. Surprisingly subverted in the Season 6 finale however, when both put their animosity aside in order to try and save Quentin. In Season 7, Black Siren apologises for killing Vincent, and she and Dinah manage to bury the hatchet and work together effectively.
    • Definitely towards Diaz once she betrays him, which he takes very badly. He later tries to kill her in order to make Quentin comply, which ends in Quentin to jump in the way of the bullet and give his life for her, which thoroughly cements her hatred of Diaz.
  • Arrogant Kung-Fu Guy: Almost literally. Aside from knowing full well how powerful she is, she has actual combat skills to boast.
  • The Atoner: Headed in this direction in Arrow Season 7, reflecting that she is remorseful for her past actions and how much Quentin's death affected her. She cemented it by becoming the Black Canary of Earth-2.
  • Ax-Crazy: She is a complete sociopath who loves nothing more than killing people. In fact she outright complains to Cayden James during a mission that there hasn't been anybody for her to murder yet. As time goes on, however, it seems that her bloodthirsty attitude was just an act, and she is far more morally conflicted about her actions than she let on.
  • Awesomeness by Analysis: She's very observant. For instance, she's able to determine at first glance that Cisco and Caitlin were not their Earth-2 counterparts when they were trying to distract her from potentially getting in Barry's way. Likewise, she was able to quickly get many details regarding her late Earth-1 counterpart to successfully impersonate her.
  • Backup Twin: Introduced not long after Earth-1 Laurel's death, she personifies the trope in many ways.
    • It was first a Deconstructed Trope, as she clearly scuffs at the idea of being made her late Earth-1 counterpart's Replacement Goldfish, and few of the friends of said late Earth-1 counterpart (particularly Oliver and Felicity) resented her for tarnishing their memory of their Laurel. Then Character Development kicks in, leading too...
    • She's also a Reconstruction both In-Universe and out. In-universe, despite repeatedly being told that she could never be their Laurel and she herself declares that she has no intention to be, living the life of her Dead Alternate Counterpart and interacting with the people on said counterpart's life helped her regain her diminishing humanity and ultimately made her a better person. In Real Life, the original Laurel's death was very controversial, mainly due to her being a very important character in the source material but also due to its half-assed execution. The then upcoming backlash is something that The Flash writers anticipated, so they wrote Black Siren as a contingency plan; in case Katie Cassidy decided to leave the Arrowverse they'd be giving her a kickass send-off, and in case if she does stay (which she ultimately did) they'd be giving her a new character to work with. Naturally, many rallied for her to become the Black Canary, seeing her as the only acceptable substitute if the original Laurel is not going to be revived (she wasn't). This is evidenced when controversial former Arrow showrunners Marc Guggenheim and Wendy Mericle decided to introduce an In Name Only character based on Black Canary despite Earth-2 Laurel's existence, a move that backfired spectacularly.
  • Badass in Distress: She's imprisoned in the Earth-1 S.T.A.R. Labs under Team Flash's custody as of Season Two. She's later incarcerated by A.R.G.U.S. after being defeated by Team Arrow.
  • Badass Longcoat: She wears a steampunk-inspired trenchcoat.
  • The Baroness: Dark Action Girl? Check. Wears leather? Check. Tall, Dark, and Snarky Aloof Dark-Haired Girl? Check.
  • Beauty Is Bad: A Statuesque Stunner note  in every sense of the word.
  • Being Evil Sucks: A life of crime and villainy sees her become a murderer many times over, a minion for a succession of violent psychopaths, Trapped in Another World, isolated from every friend she might have had, and ultimately, helpless to do more than watch as one of the few people who thought she was capable of being more than a killer dies saving her life. Small wonder that Laurel decides that she's done with being evil by the end of Season Six.
  • Berserk Button: Being told she's not like her Earth-1 counterpart, and will never be like her.
    Laurel: (to Felicity) You know, sometimes I really hate being your Laurel.
  • Big Bad Duumvirate: In Season Six, she's Cayden James' partner, though she acts like The Dragon.
  • Breakout Character: Introduced as the final Villain of the Week on The Flash Season 2 not long after the death of the original Laurel from Earth-1, she quickly became popular with fans. With her being Truer to the Text compared to the original Laurel and her existence alone being seen as a second chance to write the character properlyExplanation  while also having the potential to be a different character in her own right, many rallied for her to be the Arrowverse's official version of the Black Canary. Ultimately, she ended up being transplanted to Arrow as a recurring, then eventually main character, and finally becoming the Black Canary.
  • Breakout Villain: Introduced as a throwaway character on The Flash, she was received so well that she got transplanted over to Arrow where she would remain as a major player on the villains' side before finally being given redemption arc that fans so desperately wanted.
  • Brilliant, but Lazy: She's one of the most powerful and dangerous metas in the Arrowverse, but after Zoom is gone she seems content acting as The Dragon for normal humans, whom she could probably kill in seconds if she wanted to.
  • Celebrity Paradox:
  • Character Development: The more time she spends on Earth-1, especially around Quentin, the more Black Siren starts to show some genuine unease with her life of villainy. Being confronted by Quentin's belief that there's still good in her, as well as his memories of Earth-1!Laurel seems to be particularly affecting; she's noticeably hesitant to murder a helpless Vigilante and looked very unsettled after being forced to carry out the act, where she previously jumped at any chance to take a life and showed no remorse.
  • Chef of Iron: She's a formidable fighter and is an excellent cook, contrasting her late Earth-1 counterpart who was initially an Incompletely Trained Action Girl but a terrible cook.
  • Clingy Jealous Girl: She's a platonic version of this for Quentin. She is pissed that he doesn't think of her as his daughter or treat her the same as he did her Earth-1 counterpart. She later goes out of her way to destroy said counterpart's costume.
  • Co-Dragons:
    • She implies that she shared the position of Zoom's Dragon with Reverb.
    • She and Evelyn Sharp become enforcers for Prometheus in the final two episodes of Arrow Season Five.
  • Cold Ham: Like most villains on the show, she really likes to express it, but in a slower, slightly quieter way.
  • Color Character: Black Siren.
  • Combat Stilettos: She sports mid-heeled boots in combat.
  • Composite Character:
  • Daddy Issues: Quentin believes this is the reason why she served under so many Big Bad villains like Zoom, Prometheus, and Cayden James, because of how she lost Earth-2's Quentin at a young age and thus, is secretly searching for a father figure for guidance.
  • Dark Action Girl: Very much so, as she's a dangerous and skilled metahuman working for the Season Two Big Bad.
  • Dark Is Evil: An Evil Twin to an Earth-1 hero who dresses head to toe in black leather and calls herself Black Siren.
  • Dead Person Impersonation:
    • The Arrow episode "Who Are You"? reveals that she's the Laurel seen at the end of "What We Leave Behind", having been strong-armed by Prometheus into posing as Earth-1's Laurel to psychologically torture Team Arrow.
    • Over a year later, she was forced to publicly announce that she is her Earth-1 doppelganger who has been abducted for two years. This was because of finding herself in a literally terrible position after getting at the crosshairs of Vigilante's vengeful girlfriend whom Laurel personally (reluctantly, and under Cayden James' orders) executed, which happened not long after Cayden James's death, which said girlfriend, in turn, saw as an opportunity for payback.
  • Death Seeker: Implied a number of times. On many occasions someone against her have the upper hand, she just mocks them as if she's begging for a quick death. Notable examples are claiming to be the one who killed Cayden James' son and mocking Vigilante's widowed girlfriend on how Laurel personally executed him (despite being clearly disturbed by having to do the deed).
  • Defrosting Ice Queen:
    • In Season Six, she gradually warms up to Quentin, bonding over their similar losses and points of view about each other. By the time Quentin dies, they more or less act as father and daughter.
    • In Season Seven, post-Heel–Face Turn, she slowly becomes friendlier to her former enemies from Team Arrow, making peace with Dinah and forming a cordial, if not friendly, relationship with her, as well as developing a semblance of a friendship with Felicity.
  • Despair Event Horizon: She is Driven to Villainy by her constant misfortunes, specifically the deaths of her family and fiancee.
  • Doppelgänger Gets Same Sentiment:
    • Still grieving over the death of Earth-1 Laurel, Oliver is greatly affected by the appearance of Black Siren. Despite his continual denial, it's apparent he sees her as the original Laurel and a second chance to save her where he had failed her the first time.
    • Quentin Lance, has a much stronger emotional reaction. In fact, he has an arc where he kidnaps her to try to convince her that she can be his daughter if they both believe hard enough.
  • The Dragon: Despite being a powerful metahuman, she normally serves as the right-hand to a show's seasonal Big Bad for a reason.
    • She's Zoom's most powerful ally, and is also the final Villain of the Week of The Flash Season Two before the Season Finale. She also seems to be the only one of Zoom's minions who is aware of his true identity. At the very least, she's seen him with his mask off and neither of them comment on it. She also appears to be slightly more comfortable around him than Zoom's other minions (although she's clearly intimidated by him and takes a step back when he turns to look at her).
    • She later ends up as Prometheus' primary enforcer in the final two episodes of Arrow Season Five, assists him in battling Team Arrow on Lian Yu, and is the last of his minions to be defeated before the man himself.
    • Played with in Arrow Season Six; she acts like Cayden James' Dragon, but the man himself considers them to be partners.
    • Even with James now dead and his group essentially disbanded, Black Siren was left wandering in terms of where to go next. By mid-Season Six, however, she serves as Diaz's Number Two once he has fully come out of the shadows of James' group as the true mastermind.
  • Driven to Villainy: Crossing the Despair Event Horizon several times causes her to snap and rage against the world.
    "We live in an ugly world and the only way to survive it is to be ugly right back."

  • Even Evil Has Loved Ones: Judging from her comments to Earth-1's Oliver, she seems to still carry a torch for her Earth's Oliver. She's also gentler with Quentin than with anyone else and doesn't seem to be completely mocking when she calls him "Daddy".
  • Even Evil Has Standards:
    • She seems uncomfortable with Zoom's ultimate Evil Plan, the details of which she doesn't know. Might be subverted in Season Six, where she's very much aware of Cayden James' plan to destroy Star City and doesn't raise a single objection.
    • Cayden James' order for her to kill Vigilante while Dinah is Forced to Watch is enough to give her serious pause, and although she does go through with it under threat, she looks distinctly unsettled by the deed afterwards.
    • The more time she spends in Ricardo Diaz's company, the more she seems disturbed by his capacity for violence, being especially unsettled when she watches Diaz murder his childhood bully by burning the man alive.
  • Evil Brunette Twin: Invoked. Both she and Earth-1 Laurel are brunettes, but Black Siren first appeared during the time Laurel was still technically dyed blonde (Earth-1 Laurel recently died during Black Siren's debut). By the time she reappears in Season Five of Arrow, Black Siren has dyed her own hair blonde.
  • Evil Doppelgänger: For Laurel. Subverted post-Heel–Face Turn, although she's still more violent and snarkier than Earth-1 Laurel ever was.
  • Evil Is Hammy: She's not unlike Killer Frost in that regard.
  • Evil Is Petty: Black Siren seems to be quite jealous of her Earth-1 counterpart, and goes out of her way to insult her, especially to her friends. In the Season Six premiere of Arrow, she even tries to destroy Earth-1 Laurel's Black Canary costume out of nothing but sheer spite.
  • Evil Wears Black: She's Black Siren and is evil as they come. At least initially.
  • Faux Affably Evil: Black Siren often smiles and winks at people and speaks in a pseudo-friendly tone, but it comes off as smug mockery. She does show signs of sincere affability towards Quentin and (possibly) Oliver. Post-Heel–Face Turn, she's become more of a Jerk with a Heart of Gold.
  • Form-Fitting Wardrobe: Wears a figure-hugging leather outfit sans the hemline of her Badass Longcoat.
  • For Want of a Nail: On Earth-2, she became a metahuman due to being in Central City at the time. Her power is also an organic version of her Earth-1 counterpart's sonic device. It's also heavily implied that she uses her first given name instead of her second unlike her Earth-1 counterpart.
  • Glass Cannon: She is a very powerful metahuman capable of destroying structures who also has prowess in physical combat. Despite these skills, she is prone to attacks which is not helped by (or probably because of) her fondness for Evil Gloating.
  • Gothic Punk: Her costume design is heavily inspired by Medieval fashion.
  • Green-Eyed Monster:
    • Despite all her comments about believing her Earth-1 counterpart to be weak, there are hints that she's more than a little envious of her.
    • She really hates Dinah Drake for "replacing" her. They've managed to bury the hatchet by Season Seven.
  • Harmful to Minors: Her father got run over by a drunk driver on her own birthday.
  • Hates Being Alone: Her penchant to work with/for different characters, evil or not, in the first chance she gets heavily hints at this.
  • Heel–Face Turn: Motivated by a fear of Diaz, and later, a desire to live up to the person Quentin thought she was capable of being, Black Siren pulls one of these near the end of Season Six, cementing it in Season Seven by taking a level in kindness and becoming an ally (albeit an aloof and not exactly trusted one) for the heroes.
  • Hell-Bent for Leather: Her outfit is overall very leather-y. Those not covered by leather shows fishnets.
  • Hello, Attorney!: Her Dead Person Impersonation of the late Earth-1 Laurel sees her having to assume the latter's job, even getting promoted to District Attorney. And she's just as stunning.
  • Heterosexual Life-Partners: After they move past their issues and bond over their hatred of Diaz, she and Felicity effectively become this in Season Seven. Black Siren is the only person in Oliver and Felicity's circle to know about her pregnancy besides Diggle (though that's because she figured it out on her own), helps Felicity hide said pregnancy, and when she decides to go back to Earth-2 to atone, Felicity is the one to give her Earth-1 Laurel's Black Canary suit. Like Quentin, Felicity refused to give up on her, and it ultimately payed off in the end.
  • Hero with an F in Good: Facing the immediate consequences of her dark deeds, she struggled on her Redemption Quest.
  • Heroic Comedic Sociopath: After her Heel–Face Turn. She even snarks that empathy is something she's trying to learn.
  • Hero of Another Story: As atonement for her sins, she ultimately decided to become the Black Canary of Earth-2.
  • Hidden Depths: Assuming her conversation with Oliver in "Who Are You?" wasn't just manipulation, Black Siren might harbor regrets about the direction her life has taken, describing her present situation as the result of "some bad choices". Less ambiguously, she shows concern for Quentin, indicating that, despite her villainy, she still cares about her father enough that she doesn't want to see even his doppelgänger come to harm.
  • Horrible Judge of Character: After Prometheus releases her from prison, Black Siren becomes loyal to the man and helps him kidnap members of Team Arrow under the condition that he spare Quentin. Prometheus repays her loyalty and trust by leaving her and her father's doppelgänger to die while he blows Lian Yu sky high with explosives.
  • Hypocrite: Despite expressing contempt for her Earth-1 counterpart, Black Siren shows more than once that she's envious of Laurel and resents the idea of someone replacing her on Team Arrow (an opportunity, it's worth mentioning, that Black Siren roundly rejected).
  • I Just Want to Have Friends: Heavily hinted at. The last known person she genuinely shared a special connection with prior to her introduction died in a yacht accident. The people she's been with since are practically colleagues whom she mostly share professional relationships with, at times only due to gratitude. When Quentin and Felicity made genuine bonds with her, she's visibly affectionate towards them.
  • Iconic Outfit: Her outfit is more in line with her comic counterpart's than Laurel's was, particularly the choker and fishnets (and the Badass Longcoat, Depending on the Artist). And of course she ultimately dons her late Earth-1 counterpart's costume, or at least something similar to it.
  • Iconic Sequel Character: Does not appear in the Arrowverse until its fourth year during the penultimate episode of The Flash Season Two.
  • Identical Twin ID Tag: Unlike with Earth-1 Laurel, the editing team never bothered to hide Katie Cassidy's tattoos.
  • Inadequate Inheritor: While she is more powerful than her, Black Siren still has some big shoes to fill, as Earth-1 Laurel was very beloved by her friends and family, and many of them make it abundantly clear that she will never replace her.
  • In Spite of a Nail: She becomes a vigilante with a Code Name starting with Black like her Earth-1 counterpart, albeit an evil one. And by choice, becomes the Black Canary of her world.
  • I Owe You My Life: A sure fire way to earn her loyalty. She becomes loyal to Prometheus when he freed her from custody twice. The same applies to Cayden James when he rescues her from the remains of Lian Yu. Quentin and Felicity are also the first of the good guys she shows the most affections towards since they were the ones who made genuine efforts to bond with her when practically everyone else was either using her or wants her dead.
  • Irony: The death of her father was the catalyst for her Start of Darkness, while the death of her father's Earth-1 counterpart was the catalyst for her much anticipated Redemption Quest.
  • Jerk with a Heart of Gold: Crosses into this territory post-Heel–Face Turn. She's as snarky and aloof as ever, but she's out to become a better person, tries to nip Felicity's increasing extremism in the bud, helps the former Team Arrow when she can, and even asks Felicity to join her for pizza after a victory.
  • Karma Houdini: Considering her murderous and sadistic tendencies, as well as screwing over Team Arrow and Quentin several times, her getting off scot-free at the end of Season 6 solely because of a last-minute change of heart (which was arguably more fueled by fear than anything else) is a little jarring.
  • Kick the Dog: Seemingly takes great enjoyment in Prometheus' plan of teasing Oliver by masquerading as Earth-1's Laurel, only to rip away his hopes by revealing herself to be irredeemably evil.
  • Kick the Son of a Bitch: Sending Diaz falling off of a rooftop may have failed to kill Diaz (although he mentions in the following season that the fall broke every bone in his body) and bungled Oliver's attempt to bring him in, but Diaz certainly had it coming.

  • Lady of War: She is Zoom's top lieutenant and leads his metahuman army from Earth-2. She's also a more confident fighter than the late Earth-1 Laurel.
  • Laser-Guided Karma: A pretty harsh version, as Quentin was an innocent victim, but with him being killed right in front of her, Laurel was put into the exact same position as Dinah when she watched Vincent getting murdered by Laurel herself. It is at this point when she finally changes her ways.
  • Late-Arrival Spoiler: The death of her Earth-1 counterpart is brought up when she appears.
  • Legacy Character: She finally accepts to take over the mantle and costume of her late Earth-1 counterpart, though she instead decided to operate on her home universe.
  • The Lost Lenore: She did genuinely love her Oliver, and his loss hit her so hard she couldn't stand staying in Star City, leading her moving to Central City, just in time to view the night that Harrison "Harry" Wells activated his Particle Accelerator...
  • Madden Into Misanthropy: Heavily implied. Her dialogues every time she's talking about her past suggests that she wasn't always the angry and antagonistic person she is now.
  • Made of Iron: She survives being Car Fu'd by Wally and shrugs off a vibe blast from Cisco, though even she can't stand up to the pulse that knocks out all the Earth-2 metahumans. Proves to be downplayed; after Curtis shuts down her scream, she gets knocked out with a punch to the face by Felicity, and she later suffers the same fate when Quentin clobbers her from behind with a pole, almost to the point of being a Running Gag.
  • Make Me Wanna Shout: Unlike Earth-1 Laurel, her ability to cause damage by screaming comes from an actual superpower and is several orders of magnitude stronger.
  • Mook Carryover: Has been The Dragon for no less than four Big Bads across two shows: Zoom, Prometheus, Cayden James and Ricardo Diaz.
  • Of Corsets Sexy: She's wearing what looks like a corset underneath (or attached to?) her Badass Longcoat.
  • One Steve Limit: Much like her Earths 1 and X counterparts, her full name is Dinah Laurel Lance. She also implies that she really goes by Dinah, which puts her into conflict with both her late Earth-1 counterpart's mother and the Arrow Season 5 recruit.
  • O.O.C. Is Serious Business: She's more subdued around Earth-1's Quentin than she is around anyone else, with little evidence of her usual smug smiles or taunts. She even calls him "Daddy" outside of posing as Laurel.
  • Other Me Annoys Me: She hates her Earth-1 counterpart and thinks that she's weak and pathetic. There are shades of envy implied in her part, though.
  • Pet the Dog: Black Siren is nicer to Quentin than she is to anyone else, due to him being her father's counterpart; she tries to ensure his well-being, despite helping Prometheus abduct him, and even makes an effort at a genuine conversation while he's being held captive.
  • Promotion to Opening Titles: Zig-Zagged. She's originally the final Villain of the Week of The Flash Season Two (being The Dragon of the season's Big Bad) before being transplanted as a recurring Wild Card in Arrow Season Five, ultimately being promoted to series regular in the following season of the latter show. However, she is an Evil Doppelgänger to a character who originally appeared on Arrow, obviously played by the same actress.
  • Reformed, but Not Tamed: Despite pulling a Heel–Face Turn, she's not averse to a bit of brutality, notably torturing Silencer to try and get information on Diaz.
  • Reformed, but Rejected: For understandable reasons, everybody is still quite wary of her in Season 7, with Oliver even making it clear that she will never replace the original Laurel in his eyes.
  • Reformed Criminal: She ultimately decided to ditch her dark past to honor Quentin's memory and his faith that she could be better. She cements this by becoming the Black Canary of Earth-2.
  • Replacement Goldfish:
    • Implied to be the reason why Oliver briefly considered the idea of redeeming her. He eventually discards this notion after she commits one act of evil to many to the point that he tells her he never wants to see her again.
    • Made much more obvious with Quentin who constantly wants to see the best in her and sees her as a replacement for the Laurel he lost. Eventually he realises that Black Siren isn't Laurel and can never replace her but genuinely believes that she can be better then who she is currently and wants a relationship with her.
  • Rogues-Gallery Transplant: Originally appeared on The Flash for one episode, then went on to become a recurring character (and villain) for Arrow, in service of Prometheus.

  • Sarcastic Devotee: In Season Seven, having pulled a Heel–Face Turn, Black Siren acts as an ally to the heroes at times, but rarely, if ever, drops her snarky attitude.
  • Secret Keeper: It's implied that she's one of the few people from Earth-2 who is aware that Zoom and "Jay Garrick" are the same person, as Zoom interacts with her while unmasked with no comment on it from either of them. Her comments on his character in Season Six of Arrow further suggest that she knew Zolomon better than most of his other minions did.
  • She Cleans Up Nicely: Assuming the late Earth-1 Laurel's life means she was immediately hired as a lawyer, which requires her to dress formally, which unsurprisingly shows how elegant she could be.
  • Smug Smiler: She smiles in a sinister way.
  • Smug Snake: She's too fond of Evil Gloating for her own good and has been taken down by non-metahuman opponents on several occasions now.
  • The Snark Knight: Her mouth doesn't just have strong powers, it has strong (if not stronger) sass.
  • Sour Outside, Sad Inside: Her sadistic and snarky demeanor hides considerable angst over the losses she's suffered and the dark path her life has taken.
  • Spared by the Adaptation: She performs a Heroic Sacrifice in her only appearance in the DCAU. Here, she survives her debut episode.
  • Statuesque Stunner: She nearly makes the cut at 5'7 1/2.
  • Superior Successor: In terms of combat prowess, Black Siren definitely is this towards Earth-1 Laurel, being more experienced in hand-to-hand (and overall) combat and having actual metahuman powers instead of just a sonic device.
  • Tall, Dark, and Snarky: At 5'7 1/2, she's quite tall for a woman. She also happens to be a snarky Aloof Dark-Haired Girl, hitting all three trope criteria.
  • Token Super: She served as this for both Prometheus' and Ricardo Diaz's respective teams, being the only metahuman on a Badass Normal crew.
  • Took a Level in Jerkass: In Season Six, mainly because the events of "Lian Yu" killed whatever affection she had left for Quentin and Team Arrow. To be more specific, she tried to murder Dinah when she and Quentin were searching the island temple for survivors, and after Quentin shot her to save Dinah, she went all Never My Fault on him. Subverted as time goes on; she starts showing attachment to Quentin again, and for the first time, starts to show some hesitation and even remorse for her crimes. Then it's Double Subverted when she publicly fakes being Earth-1 Laurel and becomes The Mole for Ricardo Diaz, pretending to want redemption so as to trick Team Arrow into trusting her. Then it's Triple Subverted when she comes through for Team Arrow in the end by refusing to testify again Oliver and turning on Diaz.
  • Took a Level in Kindness: Despite taking her a long time getting there, she eventually decides to be a better version of herself, apologizing to Dinah for Vincent's death, helping Felicity track down Diaz, and even suggesting a means of getting Oliver out of prison. She even lampshades this, describing empathy as "a word she is learning".
  • Trailers Always Spoil: The previews for the Arrow episode "Who Are You?" reveal that she's impersonating Earth-1 Laurel.
  • Transplant: Zig-Zagged. She's originally the final Villain of the Week of The Flash Season Two (being The Dragon of the season's Big Bad), then becoming a recurring Wild Card in Arrow the following year before ultimately being promoted to series regular in the subsequent season of the latter show. However, she is an Evil Twin to a character who originally appeared on Arrow, obviously played by the same actress.
  • Trapped in Another World: She's incarcerated at S.T.A.R. Labs on Earth-1 after being defeated by Team Flash. She's later freed, then incarcerated again after being defeated by Team Arrow, this time in A.R.G.U.S. However, Prometheus breaks her out, and while she has yet to be locked up again, she shows no desire to return to Earth-2.
  • Trash the Set: She's introduced destroying Mercury Labs, then several buildings afterwards. It is implied that Zoom usually assigns her for demolition missions. She later trashes the Arrowcave while under the guise of Earth-1 Laurel.
  • Trauma Conga Line: She saw her father get killed on her thirteenth birthday. Then she lost her fianc&eacute in the capsizing of the Queen's yacht. It all culminates with her becoming a metahuman shortly after she moved to Central City to rebuild her life.
  • Truer to the Text: In many ways compared to Laurel (and the other Canaries, really).
    • Unlike the original Earth-1 Dinah Laurel Lance, she has the organic metahuman cry the character is known for.
    • Unlike the original Earth-1 Dinah Laurel Lance, it is heavily hinted that she actually goes by Dinah instead of Middle Name Basis. She only really goes by Laurel due to; a.) she's stuck in her Dead Alternate Counterpart's universe, b.) she made a Dead Person Impersonation of said counterpart, and c.) there are already two living Dinahs there (though she debuted first than the one who regularly uses the name).
    • Black Canary debuted as a villain on a The Flash medium, much like she did. note .
    • Her overall backstory note  is largely lifted from the Injustice comics.
  • Undying Loyalty:
    • After Prometheus breaks her out of prison, she develops a loyal streak for the man and willingly helps him kidnap members of Oliver's team, provided that Quentin is unharmed. Prometheus then blows Lian Yu to kingdom come while Black Siren and Quentin are still on it, showing just how much he values her loyalty.
    • Similarly, after Cayden James saves her life on Lian Yu, she carries out his plans with no hesitation, with the sole exception of killing Quentin.
    • Ultimately for Quentin himself, and unlike the previous two, this worked for the better as her bond with her late father's Alternate Self gradually took a positive effect on her. After Quentin dies, she switches to Felicity, who also went out of her way to bond with her.
  • Unflinching Walk: Tends to advance on her opponents at a steady pace, but once she's started closing in for the kill, she bursts into action.
  • Unreliable Expositor: We only have Black Siren's word that any of the Dark and Troubled Past story she told Oliver in "Who Are You?" is true. Given that she was acting on behalf of Prometheus to psychologically torture Oliver, and had already posed as her Earth-1 counterpart, whether or not she was telling the truth is up in the air. Season 6 eventually reveals that she was in fact telling the truth.
  • The Vamp: Is capable of seducing people of both sexes if she has to.
  • Villain Decay: When she first appears in Central City during the Metapocalypse, she is by far one of the most dangerous adversaries Team Flash have ever faced; she can level entire skyscrapers with her Siren Scream and it takes an eratic frequency to finally KO her. When she makes her way to Star City, however, while still an expert in CQC, her sceam now can only stun her opponents, and she is taken out by Felicity of all people after Curtis neutralizes her power.
  • Villainous Fashion Sense: She's a supervillain dressed like a frontwoman of a Gothic Punk band/group.
  • Walking Spoiler: Barry's encounter with her includes characters discussing Laurel's death on Arrow. She also underwent a Heel–Face Turn and ultimately becomes the Black Canary of Earth-2.
  • What You Are in the Dark: Given the choice between murdering Quentin (as James ordered) or sparing him, when there are no other witnesses, Black Siren chooses to let him go. Later, she starts stalking him, apparently to have some semblance of a connection with the father she lost as a teenager.
  • Where It All Began: She decides to return to Earth-2 and become its Black Canary since she plans to atone for everything she did and starting it at home.
  • Wild Card: Her relationship with Quentin makes her convictions falter several times.
  • The Worf Effect: In her debut she demonstrated that her sonic scream was powerful enough to topple a building. She has never shown this level of power since with her screams at most sending people flying.
  • You Are What You Hate: Circumstances ultimately forced her to live the life of her despised late Earth-1 counterpart.
