Black Ninja

A mercenary in Zanzibarland. Formerly a member of NASA's top-secret Extraterrestrial Environment Special Force. He is a high-tech ninja whose physical abilities have been enhanced beyond their natural limits with drugs. His body is protected by a flex armor suit.

His unit was deemed too much of a thread and disbanded, but several of its members defected to Zanzibarland.

He uses shuriken as his main weapon.

Black Ninja's true identity is Kyle Schneider, a survivor of the Resistance in Outer Heaven.

After the collapse of Outer Heaven, Schneider lost his entire raison d'etre, and began to sympathize with Big Boss's vision of creating a world where warriors can find true fulfillment.
