After witnessing the murder of his parents, Grayson swore revenge and promised to hunt down Zucco. Sensing a similar inner-rage like his, Bruce Wayne adopted Grayon to help him focus that anger into something better. Bruce was training Grayson to be more than his sidekick and hoped his adopted son would eventually take over as Batman.
