The Primal Riddle (109-111)
By Steve Englehart, Dusty Abell, and Drew Geraci
A battle with the Riddler results in Batman being badly electrocuted, resulting in a near death experience that separates his "spirit" from his body. As the soulless Batman struggles to foil Nigma's latest scheme, his "spirit" wanders around Gotham, possessing a wide variety of "hosts" from a small boy to the Riddler himself.
