Talia (TNBA): Talia returns with her father, ever torn between
her devotion to her father's his evil crusade, and her love for his
greatest enemy, The Batman. She still survived into the future, by using
the Lazarus Pit, although future Batman Terry McGinnis and Bruce Wayne
discovered the horrible price she had to pay.
Ra's Al Ghul (TNBA): The ageless Ra's Al Ghul is back,
rejuvenated by the Lazarus Pit, continuing on his never-ending quest for
power and to purify the planet for his new world order. Ra's has even
survived far in the future, by cheating death again and again. He went
head to head with the new Dark Knight, Terry McGinnis, in the future.
Addendum: Talia gave the ultimate sacrifice for her father--her
life. Whether it was done willingly, we will never know. Ra's put his
brain into her body and began implementing his plans to jump to an even
more agile body--that of Bruce Wayne. After a run-in with Terry McGinnis
and Bruce Wayne, it is unknown if he is currently alive.
