8 Man vs Cyborg 009

Murdered by criminals, Detective Yokoda's body is retrieved by Professor Tani and taken to his laboratory. There, Tani performs an experiment that has failed seven times; Yokoda is the latest subject to have his life force transferred into an android body. For the first time, the experiment succeeds. Yokoda is reborn as the armor-skinned android 8 Man, able to dash at impossible speeds, as well as shape-shift into other people. He shifts himself into Yokoda, this time christening himself as "Hachiro Azuma". He keeps this identity a secret, known only to Tani and his police boss Chief Tanaka. Even his girlfriend Sachiko and friend Ichiro do not know he is an android. As 8-Man, Hachiro fights crime (even bringing his murderers to justice).

Cyborg 009 is the story of a half-Japanese juvenile delinquent, Shimamura Joe AKA "Cyborg 009." "Black Ghost," a top-secret organization bent on promoting global warfare, kidnaps Joe along with eight other unwanted members of society from the four corners of the world and turns them into cyborgs. Though the organization intends to turn the group into super-powered killing machines, it's not long before Joe and his new companions rebel against Black Ghost and make their escape with the help of an old scientist. Once Joe and friends have freed themselves, Black Ghost sends a series of other cyborgs and giant robots in hot pursuit. Using their new powers and abilities, our heroes stay one step ahead of Black Ghost and its evil machinations, but can they save the world from its diabolical scheme?
