Lady Shiva's History
Initiation Incident
Shiva appeared in the Challenge Map pack "Initiation" for Batman: Arkham Origins. In the last Combat Map of the game, she was an enemy in the final round: Seishinteki Kyoyo. She appeared in a cloud of smoke and attacked Bruce Wayne. She was unarmed, but functioned as a Martial Artist and an armored enemy. Counterattack opportunities for her attacks were not indicated even if the player was on the Normal difficulty. Shiva only took damage from countering her attacks or stunning her and following with a Beatdown. Defeating her ended the campaign.
In that appearance, Shiva was still a student of Kirigi and was one of his most accomplished students.
Before Arkham Origins Incident
At some point before the events of Arkham Origins, Shiva came into contact with Quincy Sharp, and was able to convince him to reopen the old Gotham mental hospital, Arkham Asylum, by claiming that in exchange, her master could help him achieve his ambitions of becoming Mayor of Gotham. Unknown to Sharp, however, Shiva was secretly manipulating him into becoming the perfect pawn for her master and Hugo Strange in a twisted plan to exterminate any and all crime and corruption in Gotham for good.
Shiva also came into contact with one of her potential business rivals: Bane, who was immediately suspicious of her. Intending to find out what Shiva's real intentions for coming to Gotham were, Bane had her abducted before she could meet with her squadron and was taken to his Underground Field Headquarters where he attempted to interrogate her. Shiva remained elusive, however, and frustrated Bane enough to try and threaten her. Shiva was not intimidated in the least, and instead decided to turn the tables on the mercenary by revealing the inside information that regarded TN-1. Angry and scared that his plans had been put into jeopardy, Bane demanded to know how she had come by this information. Shiva responded by simply telling him that her "master knew a great deal of information." Realizing who her true master was, Bane demanded to know what he was planning only for Shiva to both threaten and warn him not to interfere. Not long after this, Shiva escaped her captors and reunited with her squadron.
Arkham Origins Incident
At the beginning of the night, a 30-year old Shiva was walking down an alley when she was ambushed by a gang of Thugs. Despite being vastly outnumbered, Shiva was able to incapacitate and kill them all with ease. She was then given a mission folder from one of Black Mask's Gang. Shiva, along with Bane, Copperhead, Deathstroke, Deadshot, Electrocutioner, Killer Croc and Firefly, were hired by Black Mask to kill Batman for a reward of $50,000,000 on Christmas Eve. She was seen on the video of the drone on the Batcomputer surrounded by thugs, fought them, and was delivered an envelope of Batman, who was wanted dead by Black Mask. While taking up the hunt along with the other assassins, Shiva, knowing that "The Master" was interested in him, instead opted to test Batman's mantle; intending to pick up the reward as a consolation prize if he failed the test.
Shiva first lured Batman, by using an abandoned baby carriage and a recording of a crying baby. Shiva then instructed Batman to find and save an "Innocent Man" before he died in Burnley. Shiva used her ninjas to further test his abilities. Batman was able to save the innocent police officer, that Shiva and her ninjas had captured, and also tracked down the body of another officer that Shiva had killed due to his corruption.
While disappointed that Batman had refused to agree that Gotham needed to be purged instead of rehabilitated, Shiva instructed Batman to go to Wonder Tower in Sheldon Park to finish the test, which involved a trial of Combat between Batman, a group of League of Assassins Ninjas, and herself. With Batman surviving the trail and besting her ninjas, Shiva allowed Batman to live, withdrew herself from the hunt, and said that he was as good as her master had said. Batman attempted to take Shiva into custody, but she vanished, never to be seen again.
Cold, Cold Heart Incident
After Christmas Eve, Shiva and the rest of the League of Assassins left Gotham. Even though they had left Gotham around this time their influence still remained in the city through Quincy Sharp and Hugo Strange who were carrying out the league's orders.
Between Arkham Origins, Arkham Asylum and Arkham City Incident
Much of what follows between Arkham Origins and Arkham Asylum was left uncertain. However during this time Batman has had a run in with the league and their leader Ra's al Ghul sometime after Christmas Eve and before the reopening of Arkham Asylum.
Arkham City Incident
Though she didn't make a direct appearance, her actions were ultimately responsible for Arkham City being constructed.
