First Appearance

Quote1 I've been avoiding you. It's... your background. The assassin training and all that. It's just... my childhood's so normal. I mean, Batman and Nightwing had some rough stuff to deal with growing , but... but you -- you were raised to be that guy there, and you turned yourself into of us. That's... pretty intimidating. Quote2
-- Robin src


Cassandra Cain is the fourth Batgirl. Born with the assassins David Cain and Lady Shiva as her parents, she was trained to become the perfect warrior. Her father deprived her of speech so she would learn movement and physicality as her first language. Batman adopted her into the Batman Family during No Man's Land, to replace Helena Bertinelli as Batgirl. Cassandra would eventually turn her Batgirl costume over to Stephanie Brown, and become a member of Batman Incorporated as Black Bat.


The daughter of David Cain and Sandra Wu-San (Lady Shiva), Cassandra Cain was conceived and trained from birth with the intention of creating the perfect bodyguard for Ra's al Ghul. After many unsuccessful attempts to train children from birth in martial arts to make them inculcate it like a native language (the most successful being The Mad Dog), David Cain, then a member of Ra's League of Assassins, decided the right genes were necessary to create this " Who Is All". With Ra's go ahead Cain searched for the perfect mother for this child, finding her in the Wu-San sisters of Detroit, who practiced martial arts with each other nearly every moment of their childhood in a type of sister's language. Cain sympathized with the younger sister, Sandra, when he noticed that she held back out of love for Carolyn. To "help" Sandra reach her full potential, Cain murdered Carolyn, then lured Sandra into an ambush by the League of Assassins, where he defeated her. Cain spared Sandra from death on the condition that she bear his child, and leave her for him to raise. Awed by the potential heights she could reach in her physical talents now that Carolyn was gone, Sandra agreed to Cain's bargain in order that she might go on to become the unstoppable force of nature known as Lady Shiva: creator and destroyer. Shiva's hope for her child was that she might day grow to be the force that could stop her reign of destruction.


Trained by her father to be the ultimate weapon, Cassandra was not taught to speak. Instead, the parts of her brain normally used for speech were trained so she could read other people's movements and body language and predict, with uncanny accuracy, their next move. This also caused her brain to develop learning functions different from most, a form of dyslexia that hampers her ability to read and write.

CassCain 1

When she was 8 years old, Cain decided his experiment had progressed far enough for him to test Cassandra's abilities in the real world, and took her to a hit; the target being Faizul, a 'book man' in Macau. At the time Cassandra had no idea what she was doing and believed it was only a game (an interpretation in keeping with her own reaction to what happened, and matching the interpretation of Alfred Pennyworth, an expert on children who saw a tape of events). After striking a deathblow, she "read" the target as he died, and saw death as he saw it.

Quote1 Terror and then... nothing. Quote2
--Cassandra Cain

In addition to scarring her emotionally, she realized murder, like her father's profession, was wrong, and she ran away from her father.

No Man's Land

Cassandra spent the next nine years homeless, beating herself mentally over what she'd done as she traveled the world. Entering Gotham City at 17 Cassandra came to be of Oracle's agents in the No Man's Land of Gotham City. After saving Commissioner Gordon's life from her assassin father, she was given the Batgirl costume with the approval of both Batman and Oracle. She became Barbara's ward and in a sense, the Batman's adoptive daughter. As the No Man's Land wore on, the new Batgirl was introduced to the rest of the Bat-clan with varying levels of acceptance. Usually going out the Batman's watchful eye she was finally allowed to go on a solo mission when a petrol station needed guarding against a local gang. Near the end of No Man's Land, Batman noticed her death wish and forced her to make a decision between suicidal actions and self preservation. She opted for self preservation.


Despite her notable handicap of being unable to talk, read or write Cassandra did remarkably well. Capable of understanding others' intentions due to her ability to read body language she was a more than capable listener, even if she couldn't reply. It was this trait that made her of the Batman's most loyal and trusted followers and helped her to survive when the Bat-clan became hunted by the Bloodhawks. Although the fact that she couldn't talk frustrated Barbara Gordon, she proved herself useful in other ways during a team with the spectral vigilante Ghost in hunting disappearing corpses. The running successes and final understanding of her mission as Batgirl allowed Batman to give her the privilege of running solo in Gotham City on the condition that she faced no 'costumed criminals' (Joker, Bane, Face, Penguin, etc)

Quote1 Remember. On those streets, you...are me. Quote2

From going undercover in Madras with Batman to saving local heroes from the mob, Cassandra continued to impress as the new Batgirl. Especially when, despite Batman's warnings, she went face to face with a meta-human and won. She even managed to, despite her restriction to Gotham City, make it on the reserve member list of Young Justice.

But Cassandra's career was not the only thing that was growing. In the background a rift between Oracle and Batman was slowly emerging, as was the growing image of Batman as a father figure in Cassandra's eyes but the major development was David Cain's growing longing to have his daughter back.

Batman learned about Cassandra's past when Cain transmitted a tape he had made of Faizul's death to the Batcave. Nevertheless, Batman continued to accept Cassandra. Things became more strained when a run-away psychic altered Cassandra's mind so that she could understand words. As an after effect she lost her ability to read body language and thus, her ability to fight. After she almost died while trying to protect the psychic from assassins, Batman took away her costume and began retraining her.

The training remained ineffective however, perhaps due to Cassandra's dwelling on her lost ability instead of focusing on accumulating more, and Cassandra wanted to roam the streets, with or without the costume.

It was during of these 'unauthorized' vigilante outings that she encountered her mother. Lady Shiva noted Cassandra's missing skills and offered to train in a way that will allow her to possess them again but in exchange they will fight in year. A death duel. Cassandra accepted.

Duel to the Death

Cassandra began training immediately; going after every talented fighter she came across in order to gain more skills. After hearing how notorious the Joker was with the Bat-clan, she freed him in order to apprehend him again in order to gauge just how good he was. Batman and Oracle deduced that Cassandra had not given her death wish and that it was due to guilt over her murdering Faizul. They began looking into what had brought the death wish back. Her reckless training was interrupted when an Officer was called over the frequencies. Batman's longtime ally and friend, Commissioner Gordon had been shot in cold blood.

It was during yet another training session in the Batcave that Cassandra first met her future friend Stephanie Brown (The Spoiler).

It wasn't long until Batman gave her a cave of her own to operate from and her training crusade continued as she found even more powerful opponents like Bizarro, Supergirl and Shadow Thief during the Joker's Last Laugh, as well as numerous villains during the aftermath of Our Worlds at War. These activities had not gone unnoticed by Batman and Oracle; despite Oracle's protests Batman allowed Cassandra to continue until the fateful day arrived that Cassandra fought Shiva on the building tops of Gotham City. Shiva won the battle fairly easily, killing Cassandra with a shot to a nerve cluster near the heart. After the battle, within a temple devoted to her, Shiva brought Cassandra back to life and requested another fight. This time, with her death wish satisfied, Cassandra Cain won and became the first to defeat Lady Shiva in martial combat.

Unfortunately the victory would be short lived; Bruce Wayne was in jail suspicion of murder. Cassandra arrived back at the cave in time to see Batman leave. It was during an investigation into the murder that Cassandra discovered that Batman and Bruce Wayne were in fact the same . Later she, along with Spoiler and Nightwing, discovered critical clues that pointed to Bruce Wayne's innocence and, eventually, incriminating evidence to the real culprit: David Cain. Her father safely behind bars and no battle-to-the-death with Shiva to train for, Cassandra focused on her crime fighting career.

Tough Love

Batgirl makes a mistake due to stress, and Oracle insists that they vacation on a cruise liner. Superboy attends the same cruise, and together they stop a terrorist named Black Wind. Superboy gives Batgirl his number, and Batgirl kisses him. Batgirl goes on date with Superboy in Smallville, but they end deciding to just be friends. Batgirl and Batman work together when Doctor Death tries to auction his chemical weapons in Gotham. They pursue him to Tarakstan, where they're forced to ally with Black Wind. Doctor Death is shut , and Black Wind sacrifices his life to contain the chemical weapons.

Barbara Gordon lends her old costume to Cassandra, who briefly uses it on patrol. Batgirl investigates a new drug called Soul. This leads her to a street gang called the Lost Girls, and she has to take them while dosed with Soul. Batgirl hunts and stops a serial killer named Doll Man. When she tries to stop a white slavery ring, Batman is angry at Batgirl for ruining his sting operation. Batman tells Cassandra that she has been making too many mistakes recently, and forces her to resign as Batgirl. Despite this, she returns to the streets in Barbara Gordon's costume. Investigating Soul leads her to the scientist supplying the Lost Girls, who is revealed to be Doctor Death. Doctor Death doses Batgirl and Batman with concentrated Soul, and they fight to the death. This allows them to reconcile. Batgirl has a tender moment with Batman, and she explains that her father never let her display affection. Batman asks who she is loyal to, and Batgirl responds that she is loyal not to him but to their symbol. Robin takes Doctor Death into custody. Cassandra begins enjoying her new freedom, and Oracle takes her to a public garden. This garden is revealed to be a plot by Poison Ivy to recreate the Garden of Eden. Batgirl blows Poison Ivy's Tree of Knowledge and stops her.

Stephanie Brown becomes the new Robin when Tim Drake quits, and Batgirl teams with her to take the Penguin. Batman has Batgirl stage a public fight with Onyx in the Iceberg Lounge to improve Onyx's street credibility. Batgirl is later sent to protect Tim Drake when Scarab is hired to kill Robin. Batgirl stops a robot called Project Mars who is trying to destroy the public library. This reveals that her illiteracy is still a problem when she has trouble determining its self-destruct code. When Stephanie Brown is fired as Robin and told to give crime-fighting, she approaches Batgirl to thank her for their friendship.

War Games

Gotham becomes a war zone when the leaders of several crime syndicates are killed, leaving a massive vacuum. Batgirl is sent to deal with the Lucky Hand Triad in Chinatown when Kwan Lin is killed. She helps Onyx and Orpheus put a battle between the Hill Gang and the Latino Unifieds. Batgirl pursues Alexandra Kosov of the Odessa Mob into an explosive firefight, but loses her. Tarantula fights Batgirl and rejects her offer to bring the Latino Unifieds the protection of Orpheus. Batgirl confronts Spoiler and tells her to get off the streets, but Spoiler does not listen. Batgirl, Batman, and Nightwing stop a shootout at Louis Grieve High School to rescue Tim Drake. This incident is the first time Batman is caught on film, which also reveals Batgirl's existence to the public.

Oracle tells Batgirl to push on when Commissioner Akins declares a curfew. Batman reveals to Batgirl that the gang war is of his experimental war games somebody stole. Batgirl protects Leslie Thompkins against an attack by Lynx and the Ghost Dragons. Lynx is accidentally killed by of her own henchmen aiming at Batgirl. There is a massive blackout and the Batman Family are blamed for it.

Batgirl is placed on the perimeter at Robinson Park when Black Mask starts a riot while posing as Orpheus. They're forced to fight every criminal in the city until the riot disperses. Batman sends Batgirl to deal with Killer Croc and Suicide King. Batgirl tells Batman that Spoiler is responsible for the war games, but Batman already knows. Batgirl rescues Onyx, who is being tortured by Croc's henchmen. The final confrontation with Black Mask is at Gotham Clock Tower, where police are told to shoot vigilantes on sight. Batgirl bravely helps put Scarebeast and then escapes the law.

Fresh Blood

Following War Games, the Gotham City Police Department declared all costumed heroes illegal. Because of this and Nightwing being injured during the War Games, Batman suggested that he and Batgirl move to Blüdhaven, as well as financially supporting the . There, she quickly made a name for herself by defeating the Society of Evil. Deathstroke later took on a contract from the Penguin to kill Batgirl and decided to let his daughter Rose Wilson (the current Ravager) do the job instead. Cassandra beat Rose by critically wounding her and giving Deathstroke no choice but to get her medical attention. It was during fathers' day that Cassandra became infatuated with knowing who her mother was. Interrogating all the contacts she had (including Batman and her father, David Cain) she eventually found her mother to be Lady Shiva.

Justice League Elite

Cassandra joined the Justice League Elite, masquerading as an assassin named Kasumi to monitor the team for Batman and participated in several missions with them. Ultimately she helped them save the world from the Worlogog and a psychic impression of Manchester Black that had taken over the team's leader, Vera Black. She revealed herself to her teammate Coldcast to tell him that he was not a bad before he was accused of murder due to the death of a target on a mission, and stood by him in clearing his name.

League of Assassins

Main article: Robin: Wanted

Returning to Gotham City Cassandra discovered that not only had her adoptive family left on a year-long training trip without her but that Batman had left a recently cured -Face to protect Gotham in his stead. Despite this Cassandra still retained the Batgirl persona and patrolled Gotham while staying at Wayne Manor Alfred's care. Due to Alfred's influence Cassandra would gradually learn to read and write due to her attending ESL classes between her nightly activities. It was during of these patrols however that Deathstroke managed to not only inject her with a controlled dose of his serum but influence her enough to join him in a plan to form an army involving David Cain's 'daughters'. Slade's influence Cassandra gained control of a part of the League of Assassins, assassinating Nyssa al Gul in the process, and became a member of his Titan's East. As leader of the League of Assassins she also, again Slade's control, attempted to kill Kara Zor-el and masterminded the escape of David Cain from prison. She would eventually be freed from the serum's influence when Timothy Drake injected her with an antiserum during a confrontation between the Teen East and the Teen Titans, however, suffering residual effects of the drug, she briefly worked for David Cain in attaining the drug Pheno before fully coming to her senses and returning to the Bat Family.


Feeling partially responsible for what happened to her Batman allowed her to return after a strict detoxification program and had her strict curfew. Nightwing however was not so accepting, regarding her with open hostility and suspicion. When Cassandra began seeking vengeance upon her father and Slade for drugging her she had to do it secretly due to their mistrust but eventually she was found out, resulting in her clashing with Nightwing and stealing a Batwing from the Batcave. The ordeal however resulted in Cassandra being cleared from the suspicion of Slade and her father’s influence and being officially adopted as Bruce Wayne's daughter.


With Batman's invitation Cassandra began working in the Outsiders team and, despite some mistrust from some members due to her recent activities Slade, she was accepted as part of the team. However when Batman suddenly disappeared without word or warning and Cassandra took it upon herself to lead, the team fractured from an attack by the Black Glove and a shunned Cassandra was left to return to a demolished Batcave.

With the absence, and now suspected death, of Batman Cassandra created the Network as a countermeasure to his absence. This action was not well received by Nightwing who was having trouble coming to grips with his adoptive-father’s possible death. The would eventually sort out their conflict after Alfred intervened on a fight between the . Cassandra handed over further creation of the Network to Nightwing.

When the third crisis hit Cassandra was among the heroes responding to an Article X draft to combat the rise of Darkseid.

Cassandra has also been seen assisting Girl and Wonder fight an incarnation of the villainous Chang Tzu

Batgirl Rising

Following the Battle for Batman's cowl Cassandra began to feel emotional about her adoptive father's death, becoming disillusioned and passing her costume on to Stephanie Brown who becomes the new Batgirl. Cassandra leaves via the Gotham Airport, warning Stephanie not to follow her. After Batman's return, it was revealed that Cassandra had handed over her Batgirl mantle to Stephanie, acting her mentor's order in the event of his death or disappearance and because giving over the role would help Stephanie become a stronger hero. Drake had been in regularly contact with her, implying that she's been working as an anonymous agent in Batman's plans.

Shortly thereafter, Red Robin visited her in at Hong Kong to exchange information on cases they were working with, on the crime boss and possible undercover cop Lynx and a mysterious assassin known as Cricket that Cassandra was searching for. Aside from the minor aid they offered each other, Tim had brought her a new costume with a Bat on it to replace the plain black costume she had been wearing even since she gave her Batgirl uniform and name to Stephanie, telling her that it didn't matter if she called herself Bat-Chick, Knightbat, or Black Robin, she had a family. She thanked him but said that family is not always home as she left, giving no sign she'd use the new costume but taking it with her regardless. Drake noted that despite her not wanting to be Batgirl any more, there was no sign she was being anything but true to herself and who she had wanted to become.

Batman Incorporated

Blackbat 003

Blackbat costume and identity

Main article: Batman Incorporated

Cassandra later becomes an operative of Batman Incorporated protecting Hong Kong, using the suit given to her by Tim and calling herself Blackbat. Bruce Wayne has her take a neo-heroin smuggling operation.

Black Bat traveled to Paris following a homing signal to Red Robin to the final site in a tournament of assassins, saving him from being raped by Daughter of Acheron, Ra's al Ghul's half sister, and defeated the vigilante Promise while freeing Drake. Cassandra then proceeded to take a sword and impale Tim in the chest, triggering confirmation that she had won the tournament, being only the in history to do so, and activating a system that would 'immortalize' her, by killing her with a laser. Red Robin saved her from the beam, and the revealed they had faked Red Robin's death, using a trick sword, blood packets, and a stopped heart to fool the temple's automated systems. They attempted to examine the base, but although Tim conversed with the assassin tournament's creator, a previously unknown centuries old immortal, the base self destructed before they could learn any close as to his location.

Red Robin came to Hong Kong to assist Black Bat in Cassandra's hunt for Cricket, but Red Robin and Black Bat were defeated by the super-fast assassin, badly injuring Tim including having an arm and several ribs broken, and Cricket promised to fight Cassandra 'For real' next time.
