The result of a brief fling between Batman and Talia al Ghul, Damian Wayne was raised by the latter and trained by the League of Assassins. His aging was sped up to the point where he had the physiology of a 10-year old child in less than 5 years, as a result of the scientific technology that the League had at their disposal. At an early age, he became a skilled assassin and a respected member of the League. When Talia deemed Damian ready, she sent him to seek out his father, Batman, who was unaware of the former’s conception. Once Batman met Damian for the first time, he was shocked, but was inquisitive anyway. In spite of his training, Damian was sympathetic to Batman’s vigilantism and offered to be the latter’s next sidekick, to which Batman agreed and bestowed upon Damian the mantle of “Robin”, the fourth to use the name. They would fight crime several times together, and Damian even developed a fraternal bond with Nightwing, a previous ward of Batman.

Sadly, because of his upbringing with the League of Assassins, Damian has always struggled with Batman’s non-lethal code of honor. Now in direct opposition to his father, Damian seeks a new mentor in Superman—whom he considers to be more of a father than Batman ever was. This is further driven after Damian killed Dick Grayson (somewhat accidentally) five years before the events of Injustice, whom Batman considers to be more of a son than Damian.

Damian Wayne should sound rather bitter and resentful, and yet still a bit of an angry and angsty teenager. Please refer to the performance by Scott Porter from Injustice 2 for the voice.
