Batman #85

In "The Challenge of Batwoman," a young woman with a mysterious past takes it upon herself to revive a man she believes is the fallen Batman—only to find he’s actually the mastermind behind a criminal gang. With Batman injured and forced to stay out of action, he and Robin quietly play along, hoping to uncover the truth before the deception spirals out of control.

In "The Second Boy Wonder!", the Dynamic Duo return to the Bat-Cave after fending off Gorilla Hardy and his gang, only for Robin to reveal a startling truth: he’s not the usual Dick Grayson, but Fred Loyd, a replacement who stepped in after the real Robin was injured. The moment cracks open a new chapter in Gotham’s crime-fighting duo, with Batman facing a mystery not just in the streets, but in the very identity of his partner.
