The Batman & Scooby-Doo! Mysteries #5
Dr. Kirk Langstrom believes the cure for his monstrous alter ego lies in studying the infamous Dr. Jekyll. When Batman accompanies him to Jekyll's abandoned lab, they're attacked by the ghost of Mr. Hyde himself! The Mystery Inc. gang has a history with this so-called spook, so Batman calls for their help. But, like, no one told them they might be facing Man-Bat, too!
