When did Neal Adams start Batman?

Adams had his first collaboration on Batman with writer Dennis O’Neil. The duo, under the direction of editor, Julius Schwartz, would revitalise the character with a series of noteworthy stories reestablishing Batman’s dark, brooding nature and taking the books away from the campy look and feel of 1966-1968.

Adams introduced new characters to the Batman mythos beginning with Man-Bat co-created with Frank Robbins in Detective Comics #400.

The same creative team revived Two-face in Batan and revitalised the Joker in The Joker’s Five-Way Revenge in Batman #251, a landmark story beginning the character back to his roots as a homicidal maniac who murders people on a whim and delights in his mayhem.
