The Black Ninja cult convenes on the island of Takoshima, in the North of Japan. They are a somewhat evil cult of ninjas who hate the light. They are enemies with almost everyone but especially with the white ninja cult. When they heard of a furon going to the white ninja cult, they quickly went to fight to the death. Cryptosperidium 138 defeated them and acquired the white ninja's datacore. Afterwards, Cryptosperidium 138 attempted to turn the black ninja cult over to Arkvoodle, by defeating every Black Ninja. However, a few Black Ninjas still survived and attacked the Arkvoodle cult saying that Crypto had tricked them. Later, Crypto, disguised as a black ninja, was given a mission to kill shama llama by the Ninja Leader. He completed his mission with the greatest ease and skill.
