## Laurel Lance

Cynthia Lance (adoptive daughter)

**Dinah Laurel Lance**, simply known as **Laurel Lance**, is a female Meta-human who was a former citizen of Starling City and a former notorious meta-human criminal. Laurel is the daughter of the late Quentin Lance and the girlfriend of the late Oliver Queen. After exposure to the dark matter released from the S.T.A.R. Labs particle accelerator, Laurel gained the ability to scream at a high frequency. Being bitter and heartbroken due to both her father's and her boyfriend's deaths, she chose to use these powers for evil and adopted the name **Black Siren**.

Laurel was brought over to Earth-1 to partake in the killing of the Green Arrow and personally fought him, until she was defeated by Team Arrow and imprisoned in their lair. Half a year later, she was released by Felicity Smoak/Overwatch and aided in her vendetta against Oliver Queen, all resulting in Queen Manor blowing up. Surviving all this, she was rescued by Ricardo Diaz and also helped him in attempting to kill Green Arrow but was shot in the stomach and badly injured. Quentin Lance then took her in against her will and helped her recover and keep her safe from Black Canary. Black Canary later found her and attempted to kill her again but Black Siren escaped. Team Arrow eventually manage to convince Laurel to be good and overthrow Slade and in the final battle between Team Arrow and Deathstroke, Laurel sacrificed herself in order to save Quentin and her dying words to him were, "thank you for believing in me".

Upon deciding to right her wrongs, Felicity gave Laurel her Earth-1's counterpart's suit, allowing her to take up the mantle as **Black Canary** of Earth-2 and later Earth-1.

## Biography

### Early life

Laurel was born and raised in Starling City. Little is known of her earlier life but on her thirteenth birthday, her father went to get her a birthday cake at her favorite confectionery, Carlye's, and was killed in a car accident collision by a drunk driver, leaving her traumatized as she was informed of it by a phone call that same evening; for years she tried to cope with an intense and overwhelming sense of guilt and sorrow as she grew up without a father.

At some point during her early youth, Laurel met Oliver Queen and they fell deeply in love. However, in 2007, when Oliver went out to sea in the Pacific with his father Robert, their ship sank and Robert was the only survivor. This made a more heartbroken Laurel fall even deeper into depression. Laurel, now travelling down down a dark path and not coming back out of it, began to make a series of bad choices.

### Becoming a meta-human

On December 11, 2013, Laurel was one of the many affected by the explosion of S.T.A.R Labs' particle accelerator, while under unclear circumstances where Laurel was most likely screaming, and gained the power to emit sonic screams, powerful enough to kill people and take down entire buildings. Using these powers for personal gain she became a criminal named "Black Siren".

Sometime after becoming Black Siren, Laurel faced off against Iris West/The Flash.

### Invading Earth-1

In 2379, Laurel was desperate for money, so she got a job from a meta-human who could breach to other Earths. She had to kill the Green Arrow and bring back his hood. She was very desperate for money and quickly accepted. Laurel first attacked Mercury Labs, to get Green Arrow's attention, and levelled the entire building, but with Supergirl's help, everyone inside was saved. Next, Laurel lured out Green Arrow into the streets to fight him. At first, he mistook her for Earth-1 Laurel Lance, who was his girlfriend at the time, and tried to reason with her though she simply laughed in amusement and attacked him. Laurel used her sonic scream to weaken Green Arrow and then physically attacked him and easily subdued him, but before she could kill him, Earth-1 Laurel ran her car into her and helped Green Arrow escape much to her annoyance.

Laurel later met up with the meta-human who hired her, who revealed his name to be Reverb, at an old warehouse on the outskirts of Starling City, bragging about her defeat of the Green Arrow but Reverb shot at her with his breaching powers, knocking her to the back of the room. Laurel quickly got up and was about to scream but was taken aback by Reverb standing directly in front of her. He told her to just get the job done and breached back to Earth-2.

Laurel, as instructed, went to demolish another building but was confronted by Earth-1 Laurel. Black Siren was annoyed to see her doppelganger, she questioned why she was here and if she had a deathwish. Laurel tries to talk Black Siren out of doing more crimes and tells her that she can be helped. However, Black Siren considers herself to be nonredeemable and screams at Laurel, knocking her into the wall. Just as Black Siren is about to finish Laurel off, she is hit with a sonic wave from a device created by Cisco Ramon that rendered any Earth-2 being unconcious.

After falling unconscious, Laurel was locked up in the Arrowcave, where she attempted to escape by screaming but Cisco mocked her and she gave up with annoyance. Oliver looks at Laurel with sadness and Earth-1 Laurel asks what's wrong with him. Oliver explains that it saddens him that Black Siren had such a bad life and turned out evil, but he hopes that she can find redemption one day.

### Working with Felicity Smoak

In December 2389, Laurel was broken out of the pipeline by Felicity Smoak/Overwatch without tripping any of the Arrowcave's alarms, and offered her freedom in exchange for help in her vendetta against her enemy Green Arrow, the Earth-1 Oliver Queen. Grateful to Overwatch for giving her back her freedom Laurel agreed and they left the lair without Team Arrow knowing of the break out for some time. Felicity sent Laurel to infiltrate Team Arrow and impersonate her Earth-1 counterpart to emotionally torment Oliver. However, Laurel was hesitant upon learning that one of Felicity's targets in his vendetta was Quentin Lance, her father's Earth One counterpart, but Felicity promised to spare him if she complied with her orders and she agreed. To prepare Laurel dyed her hair blonde to further resemble her counterpart. Once Laurel looked the part she kidnapped her doppelganger and Felicity kept her in a storage warehouse while Black Siren went to the Arrowcave.

When Oliver returned to the Arrowcave Laurel was waiting for him and greeted him, he noticed that she was acting a little different when she refused to kiss him and instead went to hug Caitlin. Later at a party Cisco held to celebrate Caitlin joining Team Arrow, while having drinks Laurel almost slipped up, almost taking the wine instead of the club soda, remembering at the last second that Earth-1 Laurel did not drink.

Later, Laurel returned to the Arrowcave where Cisco had just realized her deception at Caitlin's suggestion of an evil twin of Earth-1 Laurel, Black Siren screamed at them both, knocking them backwards and expressed relief at dropping the deception. She also sadistically expressed disappointment that she wouldn't be able to hear either of them scream because of her powers one side-effect. Before she could kill either one, Oliver stopped her and while stunned to see Laurel attacking them, she used her scream on him to cover her escape making Oliver realize she wasn't his Laurel. Black Siren later met up with Overwatch who expressed disappointment that she blew her cover so soon but when she began to question her motives, she attacked her. Holding her throat closed so she couldn't scream Overwatch reminded Black Siren that her survival was dependent upon her obedience, not her questioning and she horrifyingly agreed.

Laurel later called Oliver and apologized for attacking him, telling him that Overwatch forced her to attack them and offered to help. While skeptical Oliver agreed to hear her out and they met at the Green Arrow statue. Green Arrow expressed skepticism over her story based on what he had learnt about her, but she insisted she was being used. As Black Siren offered to help, however, Vibe and Killer Frost attacked her and she used her power to knock them both to the ground, destroying the statue in the process. However, Green Arrow used a tranquilizer arrow to render Laurel unconscious.

Laurel woke up in a meta-human cell in the Arrowcave, much to her annoyance, and insisted that she was being honest about being used by Overwatch. However, Oliver expressed his distrust given what he learnt about her history. However, Laurel didn't blame Oliver for his distrust, admitting that she has made several bad choices, and told him about her relationship with his Earth Two counterpart, and how his death sent her down that path of bad choices. She then expressed her belief that she was no longer capable of being anything other than a criminal. Taking pity on her Oliver tried to convince her that nobody is beyond saving, and offered her protection against Overwatch if she told him what she knew about her. While Laurel was ultimately manipulating Oliver into lowering his guard around her words did appear at least somewhat genuine.

Later when Earth-1 Laurel gave Black Siren a glass of water she asked what happened between her and Oliver. Unlike Oliver, however, Laurel did not believe Black Siren was capable of redemption, and told her to get used to being locked up as Black Siren stared at her in contempt. However, the power suddenly went out and Black Siren used this chance to escape but was unaware Laurel had tracking technology in the glass of water she drank, hoping it would lead Team Arrow to Overwatch.

Laurel went to a warehouse to meet up with Overwatch where they were attacked by Team Arrow. While Overwatch incapacitated Killer Frost and fought Green Arrow, Laurel incapacitated Vibe and taunted Earth-1 Laurel about killing her too. Before she could Green Arrow appeared after an encounter with Overwatch and begged Laurel not to, pleading that if she kills her doppelganger she truly is beyond saving. Green Arrow tried to convince her she can still be who she was before she lost her family, and he could help her find that person again. Despite appearing to consider his words however Black Siren simply told him "she was never there" and attacked Laurel but Green Arrow protected her. As Black Siren tried to kill them both, Vibe used a dampening device to stop her from using her power, and Felicity spitefully knocked her out. Rather than being sent back to her cage in The Arrowcave, Laurel was instead transported to A.R.G.U.S. custody both for improved security measures and so Oliver can keep her close, having taken pity on her and hoping to help her find redemption one day.

Some time after, Felicity arranged for Laurel to be freed again from A.R.G.U.S. and she, along with Leslie Willis, working with Siobhan Smythe kidnapped Caitlin and Cisco from their apartments and later kidnapped Earth One Laurel as well. Siobhan later sent Laurel and Leslie to an A.R.G.U.S. safe-house that Thea and Quentin were being kept in. The sight of Laurel threw Quentin completely off and he tried to ask her what was going on and what she was doing here but when Thea tried to explain the situation to him, Leslie shocked them both and knocked them unconscious.

Laurel took Quentin to a shipping yard and restrained him in a container, sarcastically calling him "dad", though he told her not to call him that. Laurel asked if the restraints were too tight but Quentin was surprised that she cared and she told him that this wasn't easy for her, though Quentin was skeptical to believe her. Laurel told Quentin the she helps Felicity because she owes her freedom to her and has given assurances that he'll be spared from her agenda. However, Quentin scoffed at this, telling her that his Laurel wouldn't be stupid to take Felicity for her word. Laurel agreed with Quentin and acknowledged that he loved his daughter and walks away sadly. Laurel, along with Felicity and Livewire, later traveled to Queen Manor with the captive Team Arrow members and also took Oliver's mother hostage, waiting for Oliver to arrive.

Once on Lian Yu, Laurel acted as Felicity's right hand woman, and was tasked with dealing with the prisoners and patrolling the grounds, with a few thugs at her side. She brought in Quentin and John Diggle to join Caitlin and Cisco. Diggle questioned why she would assist a girl she barely knows in getting revenge on a guy she barely knows and she says that she owes her freedom to Felicity, while she doesn't owe Oliver a thing. She continues watching the grounds with the thugs, and stumbles upon Slade Wilson knocking out Oliver and handing him over. She brings him back to the rest of the prisoners, however, this was actually a ruse to free the other prisoners and they all escape. As they are leaving, they are stopped by Felicity, with Laurel and an army of thugs by her side.

They all begin to fight and Laurel personally targets Dinah Drake. They fight physically until Black Siren is about to use her super sonic scream but Laurel throws down a super sonic bomb, knocking them both down. Laurel struggles to get back up, but Black Siren gets up with ease, and taunts Laurel laughing at the fact that she thought she could beat her. Black Sire remarks that is cute and prepares to finish her off with a scream, before she is knocked out by Quentin. Laurel tells him that he didn't have to do that, but he remarks that he did for so many reasons. Laurel is left in the manor as it explodes.

She in fact survives the explosion and confronts Laurel and Quentin, she has a knife to Dinah's throat and plans to kill her but she is shot by Quentin and is believed to be dead. It turns out she is not dead and is rescued by an associate of Ricardo Diaz who helps her up and leaves the manor.

### Working with Ricardo Diaz

Five months after Queen Manor, Laurel returns to Starling City and immediately attacks the Starling City SCIS Department, destroying it with her own mercenaries. She and her group are later attacked by Team Arrow on the bridge in which a fight begins between Black Siren and Black Canary, the two are evenly matched at first but soon Laurel shows that she is a superior fighter and disarms Black Canary, before knocking her and Quentin out.

Team Arrow believes that she plans to attack the SCIS benefit in order to get revenge on Quentin, so they plan a trap for her; however, Laurel attacks the lightly defended Arrowcave, she has her men set some bombs and specifically has one set on her doppelganger's suit. Laurel and her group are then attacked by Team Arrow who have finally arrived and Dinah Drake, the new Black Canary, and Laurel, fight again, but once again Laurel is able to escape before being confronted by Quentin at gunpoint. The two converse in which Laurel guilts Quentin to lowering his gun before admitting that she would have done the same thing in the manor as he did. It is later revealed that she had in fact stolen one of Cisco's prototype T-Spheres.

Weeks later Laurel begins killing three seemingly unimportant individuals, as Team Arrow is unable to anticipate her, Curtis develop a system to track her when she uses her sonic scream, tracing her in the abandoned facility of Helix in the very same moment in which Cisco and Caitlin break into it; there she is revealed to be working for Ricardo Diaz, who tasks his men to kill both the hackers; however, Team Arrow intervenes and a fight ensures driving Laurel, Diaz and their party to escape.

Later Caitlin discovers that Laurel's victims are undercover agents of the International Domain Name Directory (IDND) the global internet infrastructure, and she has stolen their fingerprints in order to enter it. Believing that Diaz intends to destroy the internet, Team Arrow attacks his party at the International Domain Name Directory vault, where Cisco manages to breach through the firewall to stop Diaz's apparent attack while Laurel fights Diggle managing to escape and later being provided by Diaz with a device to stop Curtis' tracking system.

After Oliver is arrested by the FBI, Laurel and Diaz planted a bomb under Starling Stadium during a concert, however as Oliver's trial is delayed, he suits up as the Green Arrow and tried to stop them only to discover that the bomb is fake, as well as the cops guarding the stadium; so after having recorded footages of Team Arrow beating up a group of cops, Diaz and Laurel escape.

Laurel is later sent by Ricardo Diaz to capture Quentin Lance, who was at the time being accompanied home by Thea. Quentin is easily taken but not before he witnesses Thea being knocked unconscious after a scuffle with Laurel. Thea wakes to find Laurel has left her a phone with which Oliver receives instructions in exchange for Quentin's safe return. A later conversation reveals that Laurel is still bitter over being shot in Queen Manor. When Quentin asks about his doppelganger, Laurel tells him that her father died in a car accident while retrieving a cake for her thirteenth birthday. This makes Quentin reveal that he did the same thing for his daughter, which brings Laurel to tears.

Soon after learning Oliver has betrayed him, Diaz gives Laurel the order to kill Quentin, which is delayed by her discovery of Vibe and Killer Frost nearby. Fleeing with Quentin, she spares his life, telling him to "run", shocking Quentin. Green Arrow eventually catches up with the two however Laurel is able to create a distraction, using her sonic scream to bring down overhead pipes between them, and escape into the night. After watching Team Arrow disband, it is revealed that Laurel had planted a hidden camera in the Arrowcave during her initial attack and Diaz had been watching and gathering intel on the team the entire time thus revealing how he has been one step ahead of Team Arrow. Soon it is shown that Laurel is not the only person working with Diaz as Vincent Sobel/Vigilante, Carrie Cutter/Cupid and Slade Wilson/Deathstroke all reveal themselves to be part of a larger teamup than originally thought.

Some days later Laurel, Diaz and Cupid break into Jerry Bertinelli's office in order to threaten him and force him to give them control of the port. Later, they are tracked by Green Arrow into they're lair and taken by surprise; during the ensuring fight Laurel's prevented from using her powers due to a trick arrow that tightens her throat, but is quickly freed due to the intervention of Cupid's thugs, Deathstroke's army and Vigilante. Although she suggests to kill him, Diaz eventually says to let Green Arrow go.

Shaken by her speech with him, Laurel started to stalk Quentin in secret, hiding every single time he looked back; however the man discovered it and, with the help of Thea, eventually managed to attract her to an abandoned warehouse where he attempted to reach to her showing her some tapes and pictures of "his Laurel", stating that he sees his daughter in her and believes that deep down she has her same good heart. Upset, Laurel denies everything by declaring "she is not like that" and emits a sonic scream in panic just before escaping.

Later she joins Ricardo Diaz as he sets a trap for Vibe, Killer Frost, and Black Canary using Vincent Sobel, who has been identified as a traitor, as bait. After setting up an explosion and detaining Canary under some rubble, Diaz cruelly orders Laurel to execute the traitor and, despite hesitating at first, under the pressure of proving her loyalty to the cabal, she sonic screams into Vincent's ear until his regenerative powers are exhausted and his brain collapses. Afterwards, she and Diaz left the scene though for the first time Laurel showed remorse for killing someone.

When Diaz revealed that he planned to release the bomb, he informed Laurel, Slade and Cupid that he has planned for a helicopter to arrive to take them away from Star City, however Slade doesn't believe this and intends to leave his own way, Laurel agrees and goes to her secret stash, which included a photo of her doppelganger and Quentin, but she was unable to leave as Earth-1 Laurel caught up and fight to her in order to avenge Vincent, Black Canary's rage against Laurel gave her an advantage but Quentin soon arrived to stop their battle. Black Canary asked Quentin to leave but he didn't so she screamed at Quentin, knocking him through a wall, before Laurel could retaliate she was taken down with a trick arrow by Oliver and held at gunpoint by Diggle. After Diaz discovered that either Laurel or another member of his team killed his daughter, he arranged a deal with Oliver to bring them all to him. Laurel refused to leave Black Siren alone and Quentin refused to leave Laurel alone with Black Siren; as Laurel placed a dampener on Black Siren, she mocked her talking about how she killed Vincent. Once Oliver and the team captured the other members of the Cabal, Quentin and Canary brought Laurel to the meeting, there Quentin and Laurel talked and she stated that the only way to survive is to be cruel, explaining that she can't be redeemed. Then Laurel is brought to Diaz along with the others and he demanded the one who ordered the murder of his daughter to come forward; Laurel revealed she did it but Diaz slaps her and told her he knew she didn't, revealing to everyone how she hesitated in killing Vincent. Unknown to everyone else, the bomb detonator caused her collar to malfunction allowing her to use her powers again, so she used it on Diaz before having the dampener destroyed and then using it on everyone else. She attempted to escape but was stopped by Black Canary, the two brawled until Quentin arrived trying to stop the fight but Canary disarmed him and shot at Laurel who fired her cry at her knocking her out, a moment before falling unconscious due to the bullet wound, Quentin saved her life and patched up her wound before taking her to his car and handcuffing her so she couldn't escape, when Laurel woke up and discovered her predicament, Quentin told her that he was planning to find the small piece of his Laurel inside her, knowing that what she stated was a lie and that the revelation that she hesitated to kill Vincent means there is still hope for her.

### Joining Slade

Quentin took Laurel to a secure cabin in the woods in order to allow her to heal and convince her that she can be a better person, Laurel lets herself be persuaded and told about her counterpart from Quentin to see how much she really had in common with her. After Thea found out about it, Laurel told her to contact Oliver in order to make a deal; she will return the city's money stolen by Ricardo Diaz (which she previously withdrew from his off shore account in Corto Maltese) if they get her out of the country; Oliver accepted and Quentin offered to accompany her and help her start a new life, convinced that the presence of someone supporting her would change Laurel for the better. As Black Canary arrived at the cabin ensuring a fight between her and the team, Quentin tried to take Laurel away but is soon intercepted, brutally attacked and quickly knocked out by Canary, who later rages on the still convalescent and weakened Laurel, failing to kill her only thanks to the intervention of Cisco who talks Canary out of it, allowing Laurel to get enough time to incapacitate them both with her own sonic scream and escape.

Later that night, Laurel was crying in pain, lying helpless on the side of a road on the outskirts of the city when someone walks in front of her and helps her up. The person reveals himself to be Slade Wilson. Slade offers Laurel some stiches and a seat at his table of criminals. She agrees, of course in her state, agrees.

When Oliver and Thea are talking about how they are going to get the money back for the city, the building begins to shake and collapse, with Thea almost being crushed. Oliver contacts Cisco in the Arrowcave and asks him to breach The Flash to this Earth to help get everyone out of the building. In a matter of second, Oliver and Thea are both out of the building surrounded by a crowd of people and as the building looks like it is about to fall, Flash manages to steady it as Supergirl flies in and helps out. Black Siren then reveals herself, however, wearing a mask so that the crowd wouldn't recognize her as Laurel Lance. She screams at both of them knocking Supergirl into a nearby building and The Flash into another. Oliver is about to run off to get his suit until he sees Vibe and Killer Frost breach in and they both hit Siren with their powers knocking her into a wall and almost incapacitating her. However, Siren screams into the whole crowd, distracting everyone and covering her escape. She is later seen with Cupid and Deathstroke sitting around a table and plotting their next move.

Laurel later gets a visit from a distraught Quentin Lance who goes to hug her but she punches him and puts him into a chokehold. Laurel asks what the hell he's doing here and he explains he wanted to see the woman who's acting like more like his daughter than his actual daughter. Laurel lets him go but tells him to get out before she's forced to call Slade, who will definitely kill him. However, before Quentin goes he hugs Laurel and tells her to be safe and leaves, leaving her very confused. Later that day she is abducted herself by Team Arrow, who plan to talk some sense into her. Oliver tells her that she doesn't have to be afraid of The Black Canary because he will keep her safe, Laurel tells him to get stuffed but right after he kisses her and tells her it's just like old times. Laurel begins to get choked up and tells them to let her go before she kills them all, Oliver reveals that she doesn't have a power-dampening collar on her, and he tells her to kill him right now if she has the guts. Laurel takes a heavy breath in but breaks down in tears yelling, "I can't do it, Ollie. I can't hurt you!" Oliver tells her that's good, unties her and gives her a hug. He then asks her to tell him everything she knows about Slade and his plans and she agrees.

### Death

Slade calls Black Siren and Cupid to Bludhaven for the final fight between them and Team Arrow. Slade doesn't know that Laurel is actually helping the team take him down. When they arrive the three villains prepare for battle until Slade tells them all to calm down as one of his men carry out Oliver's son, William, with a knife to his throat. Both the team and Laurel look shocked as some of Slade's men turn their guns on Laurel too and Slade confesses he knew Laurel didn't have the stomach for what he had planned. Just as Slade begins to gloat and laugh, Cisco breaches in a bomb that drops in front of them all and knocks all of them back. Cupid senses that this isn't going to end well and she attempts to run but Speedy hits her in the back with an explosive arrow that knocks her out instantly. Quentin and the SCPD barge in and begin shooting but Slade grabs William and Oliver tells them all to stop. Slade gloats about how satisfying this kill is going to be when he gets hit from behind by Laurel's sonic scream, he gets up, angrier than ever, and the two begin fighting. Laurel appears to overpower him before Slade grabs her leg and twists it and she screams in pain. Slade then proceeds to stab her in the stomach with his sword, leaving her to die. Oliver eventually defeats him and rushes over to check on Laurel who has Quentin by her side. Laurel thanks Oliver for believing in her and for letting her be a hero. She then says she can be with her Oliver and her father now and she shuts her eyes, dead.

### Resurrection and becoming Black Canary

Laurel was resurrected by Barbara Kean, 9 months after her death, Laurel has become good and became a vigilante known as Black Canary and saved lots of people in Star City from criminals and assassins.

## Personality

Eventually Laurel lost touch with her humanity, as she became a cruel and sadistic individual who revels in the destruction that she causes with her powers..

Laurel is a very convincing manipulative-liar, as noted by Oliver, to which Laurel admits, successfully imitate her Earth-1 counterpart and fooling those closest to her for some time including Oliver, her counterpart's ex-boyfriend and oldest friend.

Despite her cruel and sadistic nature, Laurel does still have some humanity, admitting to Oliver that talking to him was difficult as she loved his counterpart and initially hesitated when he begged her not to kill Earth-1 Laurel. She also has genuine sentiment towards Quentin, her father's counterpart, and despite her contempt towards her own counterpart, she is sympathetic towards Quentin. Laurel also has in her own way a personal sense of honor, as she agrees to work for those who have saved her life due to feeling indebted to them. Oliver also believes, despite her own denial, that Laurel isn't beyond saving and hopes to one day help her find redemption.

However, after the events in Queen Manor and being shot by Quentin, Laurel's sympathy towards him seems to have disappeared. She also seems to be more cruel and sadistic than she was before, due to her recent killing spree; however, Laurel could not bring herself to kill Quentin, despite being ordered by Ricardo Diaz to do so, even when she had more than enough time to kill him, instead she let him go; possibly because he physically resembles her late father or because there is still some good left in her.

In her final moments, Laurel proved to everyone that she was a true hero all along as she sacrificed herself to save Quentin.

## Powers and abilities

### Powers

* **Meta-human physiology:** After Laurel was struck by the energy of the S.T.A.R. Labs particle accelerator explosion on Earth Two, her DNA mutated and enhanced her vocal cords.
	+ **Superhuman sonic scream:** Laurel was able to emit a high frequency scream, that came from her voice with the highest known frequency her scream can reach being 250 decibels. Laurel's scream was powerful enough to produce enough force to launch a full-grown human and other heavy objects back several feet. Her scream was also powerful enough to kill a human being by causing internal hemorrhaging, shatter a marble statue or steel arrows, and with one shout she caused a tremor that took down all of Mercury Labs. She was well known for collapsing buildings with her powers on both Earth One and Two. Laurel is also immune to her own powers and has shown that she can control the range to her powers, causing seismic events large enough to collapse a building or small enough to enter through the ear, causing internal damage on a fatal scale even if the target has regenerative powers.

### Abilties

* **Peak of human physical condition:** Laurel was in top physical condition, with her strength being enough to swiftly incapacitate, hurl through the air, or even break the neck of a grown man as well as beat up much larger foes relatively with ease. Laurel's reflexes are fast enough for her to react to an incoming arrow in order to shatter it with her powers.[9] Laurel's durability and resilience are remarkable as she has been able to get up without any visible injuries after getting hit by Wally West's car,[3] stand up after being hit by a shockwave due sonic scream battle with Dinah Drake,[7] and survive Lian Yu's explosion and being shot in the stomach afterwards. Her conditioning also lets her recover from most injuries very quickly, though not superhumanly.[8] However it could be possible that her uniform may have materials that could have helped her survival.
* **Honed senses:** Laurel has sharp hearing and sight, as well as keen skills of perception. She is able to pick up an incoming danger and react extremely quickly.[10]
* **High-level intellect/Expert tactician/Leader:** Laurel is an extremely intelligent and observant woman, able to determine at first sight that Cisco Ramon and Caitlin Snow were not their Earth Two doppelgängers. Also, she is an accomplished leader and tactician, due to her former status as one of Zoom's top lieutenants[3] and leading her own group of criminals.[8] She has also proven to be very effective in anticipating her enemies patterns of thinking and use it against them, purposely leaving a map of City Hall for Team Arrow to find making them believe that the Star City police ceremony was her target, while actually it was the Arrowcave.
* **Master hand-to-hand combatant/Martial artist:** Laurel is a highly proficient unarmed combatant. While battling the Green Arrow, she demonstrated a series of well coordinated punches and kicks after disorientated him with a sonic scream. Laurel has proven capable of defeating Dinah Drake a highly skilled combatant in her own right, on several occasions, overcoming her bare-handed with ease even while she was armed with her signature bo-staff and managing to fight her to a stand-still even when she was fighting with the intention to kill her] as well as knocking out Thea Queen (albeit just awakened from a coma) in less than a second without giving her time to react. However, Laurel has been shown to be unable to handle herself against Adrian Chase and, despite being skilled enough to hold her own against a master hand-to-hand combatant and martial artist such as John Diggle was ultimately defeated by him.
* **Skilled stick fighter:** Laurel is an accomplished stick fighter, when Dinah Drake fought her, she took Dinah's bo-staff, and used it to take both the former and Quentin Lance down with relative ease.[8]
* **Intimidation:** Due to her incredible power and her well-known coldness, Laurel commands an intimidating presence, instilling fear into both enemies and allies.
* **Master knife-wielder/Knife-thrower:** Laurel is highly skilled with knives, she managed to quickly incapacitate Dinah Drake and hold her throat at knifepoint in order to prevent her from using her powers, all this while moving extremely fast.[8] Laurel is also skilled in using knives in long-range combat, she was able to kill a man with a single stab throwing him a shuriken before he could fire his gun even though he was in her field of vision for only an instant.
* **Free-running/Acrobatics:** Since becoming Black Siren, Laurel has developed free-running skills and could drop from a height of several feet without injuring herself. She was able to incapacitate Laurel Lance by jumping on her and holding a knife to her throat in a matter of few seconds.She was also able to perform a backflip without using her hands during her fight against Laurel. Her skills allow her to fluidly dodge and attack from different directions without losing balance.
* **Indomitable will/High tolerance for pain:** Laurel is a very resilient woman, after the explosion caused by the confrontation between her and Dinah Drake's sonic screams she was the first one to get back on her feet. She is also a very driven, determined and nearly fearless individual, as shown by not being intimidated by Hunter Zolomon, Adrian Chase or Cayden James. She was even able to survive taking a bullet in the chest, and despite being knocked out, upon awakening was able to get back on her feet and fully recovering in just six months, though it could be possible that the suit she wore have helped her on that occasion she later demonstrate to be able to survive a close-range gunshot at the stomach even while in civilian clothes.
* **Master of deception:** Laurel is an exceptional liar, as once she was given all the information about her Earth One doppelgänger, she was able to successfully portray herself as her to various people.[2] Laurel is also capable of befriending or seducing others in order to make them feel at ease with her before she kills them.
* **Stealth/Infiltration:** Laurel has demonstrated to be elusive, as after disorienting her enemies with her sonic scream she was able to quickly vanish from sight. She can just as easily catch her enemies off guard without her powers, able to disarm Laurel Lance and hold her as a hostage.

### Weaknesses

* **Vocal cords:** If someone is able to grip Laurel’s throat tight enough she is unable to use the scream to defend herself as demonstrated by Felicity Smoak.
* **Sonic dampener:** Just like Black Canary and Sean Sonus, Laurel was affected by Curtis Holt's sonic dampener, causing her to temporarily lose her powers.
* **Power-dampening tech:** Laurel's powers can be neutralized by using power-dampening tech.

## Equipment

* **Black Canary suit:** Laurel wears a protective black and yellow leather suit as her superheroine alter-ego, Black Canary, to hide her identity from her enemies when she goes out fighting.
* **Expandable batons:** After a while of being the Black Canary, Laurel has started to use two batons as her main weapons.
* **Guns:** Laurel has used guns on a number of occasions when not counting on her powers.

### Former equipment

* **Black Siren suit:** Laurel wears a black leather suit while terrorizing her victims as Black Siren. Laurel's suit is potentially very durable due to her survival of a car crash, a shockwave, an island explosion, and gunshot to the stomach.
* **Ghost phone:** Laurel uses a ghost phone to call Oliver.
* **Anti-tracking device:** Ricardo Diaz provided Laurel with a device that can prevent Cisco Ramon/Vibe from tracking her sonic scream.
* **Knives:** Laurel has used knives on several guards and uses one to free Quentin Lance. Despite greatly relying on her powers or hand-to-hand combat skills, knives seem to be Laurel's weapon of choice, and she has proven highly capable of wielding them proficiently.
