Shinobi

Game: Shinobi
Genre: Action/Adventure
Year: 1987
Biters: Ryu Hayabusa (Ninja Gaiden), Strider Hiryu (Strider) 

Complex Says:  Sega gave us the first ninja hero with Shinobi. He’s also one of Sega’s first heroes alongside Sonic the Hedgehog and Alex Kidd. Other ninjas bit his style, with Ryu Hayabusa from Ninja Gaiden being the most notable. Sure Ryu took off with his series, but the originator is Shinobi with his traditional ninja mask, two-toed slippers, samurai sword, and extremely long scarf.
