text: Joel dies shortly thereafter, and BJ agrees to raise his powerless son in order to prevent another such tragedy from happening (he also marries Joel's widow, Mei-Lai, sometime in the intervening years).The child, named Clark Wayne, becomes BJ's Robin and is offered the mantle of Batman when he becomes an adult. Clark turns it down, having deduced that he isn't BJ's biological son, and believing that only a real Wayne should be Batman, instead adopts the identity of Knightwing. In the 1990s, BJ goes on a quest to locate his missing father, whom he eventually discovers as having taken over Ra's al Ghul's criminal empire and turned it into a force for good. Bruce asks BJ to assume control of the organization so that he can become Batman once again. A story in Generations II has Bruce's dying wife imply that BJ isn't his biological son, but this is not explored until Generations III, where BJ uses a Lazarus Pit and becomes Robin once more, ultimately learning that he truly is Bruce's son and everything was a plan by his mother to make up for never allowing father and son to work together as heroes.
