Haō-ken (覇王剣)

The legendary sword that once wielded by Susanoo to seal Yamata no Orochi inside Japan. In Pyramid arc, when Yaiba fought Jewel, Yaiba's Raijin-ken and Fūjin-ken changed their shapes into one sword, the Supreme King Sword. It is far stronger than Raijin-ken and Fūjin-ken. It changed the wielder's fighting powers into its power.
