Batman: The Dark Knight Detective #4

In "Tulpa, Part One: Monster Maker," Batman finds himself in over his head when Looker pulls him from a deadly trap, while Karlo unleashes a terrifying transformation—using stolen blood samples from Payne and Fuller to remake himself into the ultimate Clayface. Meanwhile, the fugitive duo of Payne and Fuller discover an unexpected connection as they flee, their shared past unraveling in ways neither expected. Written by Alan Grant and illustrated with haunting precision by Norm Breyfogle—whose cover pencils and inks bring the nightmare to life—this issue blends psychological dread with the raw power of metamorphosis.
