Batman 380 (Feb. 85), by Moench, Rick Hoberg and Alcala, is one of my least favourite issues from this period.
While the Night Slayer goes after Nocturna, Batman tracks him to the blind woman who had been tending to him.
The Night Slayer captures Nocturna and Jason Todd, but through a bizarre (and rather stupid) set of circumstances, he and Batman wind up switching costumes, and Batman even becomes convinced that he is a killer.
This situtation drags on into the following issue of Detective. The less said the better, as far as I’m concerned.
