Talia al Ghul

Talia's relationship with Batman was put to the test when Ra's faked Talia's kidnapping as a way to determine Batman's worthiness as his heir, since Talia was in love with him. He passed, but eventually, Batman learned the extent of Ra's empire and tried to bring him to justice. Ra's challenged him to a duel to the death. They fought for hours until Batman was stung by a scorpion. Ra's left him to die, but Talia gave him the antidote, and Batman finally captured Ra's. Imprisoned, Ra's got revenge by framing Batman for both his and Talia's murders. He'd faked their deaths, his goal being to make Batman a fugitive and force him to become his son-in-law, but the plan failed. However, Talia's feelings for Batman were reciprocated. Batman persuaded her to leave her father and join him, infuriating Ra's. The three made a truce to take down a terrorist, and while doing so, it was discovered Talia was pregnant. But following an apparent miscarriage, she chose to stay with Ra's.

It was later uncovered that Talia's miscarriage was a lie, and she actually gave birth to Batman's son, Damian. Talia kept Damian's existence a secret from Bruce, and the boy was raised with the training of the League of Assassins almost from birth. When Talia felt he was old enough, she allowed Damian to go to Gotham City and meet his father. While Batman was surprised to learn he had a son, he readily took him in, knowing it would be important to teach Damian that the ruthless ways of the League of Assassins were not the only way to view the world. Talia and Batman clashed over Damian's upbringing, but when Talia learned that her father planned to kill her son in order to resurrect himself, she and Batman came together as parents, and she helped Batman fight Ra's.

Talia found herself on the opposite side of a family team-up when Batman and Damian learned the criminal organization Leviathan, which they had been battling, was headed by Talia. Damian refused to leave his father's side and join his mother, disappointing her. She revealed that she had created a clone of him, the obedient Heretic, and aged him to a full adult. Damian refused to stand aside in the battle against Talia and, as a result, the Heretic killed Damian. Talia planned to resurrect him in one of her family's Lazarus Pits and make him loyal to her, but Batman took Damian's body and brought him back to life using technology from Apokolips, Darkseid's home.

Talia is more than her father's apprentice—she's a shrewd leader in her own right, having led the League of Assassins and co-founded the Secret Society of Super-Villains. Also, once when she became disillusioned with Ra's and his plans, she left to run LexCorp for Lex Luthor during his presidency. Though she appeared loyal, Talia was secretly working against Lex, leaking his criminal activities to Superman. When the time came, she orchestrated Luthor's downfall by selling off all LexCorp assets to the Wayne Foundation, leaving Luthor broke and fully exposed.

Talia's relationship with her son, Damian Wayne, and Batman continues to be tumultuous, marked by moments of both alliance and conflict. Sometimes, Talia seems to seek redemption, attempting to steer Damian away from violence and expressing remorse for past actions and opposing entities like the Lu'un Darga, in order to protect the Lazarus Pit's power. But she remains deeply linked with her villainous organization, keeping her a confusing mix of villainy and maternal concern.
