Damian Wayne is the biological son of Bruce Wayne and Talia, and thus the grandson of one of Batman's villains, Ra's al Ghul. Talia would become pregnant with him after a sexual encounter with Bruce, but would keep their son's existence from him for a decade. Instead of being birthed naturally, Damian was grown in a lab, with the intention that he would surpass his father. Shortly after his birth, Talia would leave Damian in the care of the League of Assassins so he could begin his training as an assassin. Years later, Talia reveals Damian's existence to his father and leaves him in Batman's custody in an effort to disrupt his work and get a step closer to her evil plan. Instead of shunning the boy, Bruce acknowledged his duties as a father, and accepted him into the Batman Family, which would eventually lead Damian to become the fifth and current Robin
