2. Ryu Hyabusa from the Ninja Gaiden series
Sure, the Shinobi series is cool and all, but when it comes to badass ninjas, Ryu from the Ninja Gaiden series makes the higher cut. He has, arguably, the three hardest games in the NES library with his trilogy, and he takes it all in stride.
He also battles babes (and, er, Zach) in the Dead or Alive series, and still kicks ass on the modern day consoles. He’s a tough son of a bitch, Ryu is. We can’t get enough of the guy.
