Yaiba Kamikaze (神風 刃 Kamikaze Yaiba) is the main protagonist of the 2014 video game Yaiba: Ninja Gaiden Z.
Why He Sucks
Yaiba massacred his own ninja clan due to getting weary of his work as having to fight new ninjas due to him being a highly skilled member. Yaiba massacred his own clan for helping him become what he is.
Yaiba killed his sister, Yuki, in a fit of rage, and after his father decapitated her in order for Yaiba not to resurrect her, he killed him too.
Yaiba challenged the Ninja Gaiden series protagonist Ryu Hayabusa, claiming he is the weakest foe Yaiba faced so far but he discovers otherwise when Ryu sliced his left arm and eye, thus killing him.
He's vulgar, sadistic and amoral.
He doesn't even deserve to be a ninja as he views death as a distain instead of honorable.
His combat is terrible and poorly implemented, and executions are hard to perform.
His game killed the Ninja Gaiden franchise, until it was annonced Ninja Gaiden Master Collection, to be released in 2021 for PC and consoles.
His Only Redeeming Quality
After being tricked by the organization that brought him back to life, Forge Industries, into having killed both him and Ryu, he decides to sacrifice himself and spare Ryu's life.
