With many weapons collected, made and given to him Ku has a massive arsenal at his disposal. Stored in pocket dimensions in Hanzo and Ku’s armor the massive arsenal is always at hand to use. Known as the emperor of a thousand blades this is a small sample of the weapons Ku is able to wield. Kage could wield not all weapons but those that could strengthen and reinforced Ku’s minions. Some weapons were also formed thru the Kage process and any and all Kage (as well as Ku) could call these weapons out of thin air. Many of these easily accessed weapons were made of “Shadow Steel” a special alloy of steel using ninjitsu magic to form. This alloy gave no reflection, was more durable then steel and was half the weight. If facing the horde of weapons was not enough, weapons could also have their own specific jitsu and ultimate techniques.
