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). He smoked "energy" cigarettes, to rejuvenate his powers, that he carried in a cigarette case on his belt.
The single coolest thing about Eightman has always been the evil Popeye power dynamics where instead of eating spinach he just pulls a pack of smokes before beating up people, SNK were cowards for not including that in.
I was gonna give this an 8/10 for the funny but we have a 5 star scale here so the joke doesn't work. I don't remember really much of this game since I played it, as it's rather unremarkable.
