Armored Police Metal Jack (機甲警察メタルジャック, Kikō Keisatsu Metaru Jakku?) is a Japanese animated TV series co-produced by Sunrise, TV Tokyo and I&S BBDO. The series was broadcast by TV Tokyo affiliates in 1991 on the Monday 5:30PM time slot and aired weekly from April 7 to December 23, lasting 37 episodes. Metal Jack was originally planned as a sequel to the live-action tokusatsu show Dennou Keisatsu Cybercop, but due to complications with the show's production, it was made into an animated series instead without any official ties to Cybercop. However, due to low viewership, the length of the show's run was shortened by one cours. Head writer Hiroyuki Kawasaki would later recycled some of the same situations from Metal Jack in Brave Police J-Decker. The show was also the debut of Nobutoshi Canna (who acted under the stage name of Nobutoshi Hayashi).
