The Batman (2022) didn't have many new additions from the comics except one standout character, Chief Mackenzie Bock portrayed by Con O' Neill.
Last comic appearance in the No Man’s Land event, and he is clearly different from his comic book counterpart!
Mackenzie “Hardback” Bock's first appearance was in Detective Comics #681 (January, 1995)
Born in New York City, where he served as a police officer making a name for himself.
Lt. Sarah Essen, decides to transfer to Gotham asking Bock to join her.
