Black Spider Ninja Clan is a prominent group of villains in Ninja Gaiden Sigma and Ninja Gaiden II.
The Spider Ninja Clan are allied with Vazdah and his minions. Their hatred towards the Hayabusa Ninja Clan is unrivaled. Craving power, the bodies of the Black Spider Ninja Clan has been twisted by their hunger.
