Ninja Masters were Number Woo's elite henchmen from Asyanica. They had a fireball attack. The fireballs could move left and right, the best way to avoid them was to jump at the last second. They could make holographic doppelgängers and also use a close-range flame attack.
Hyabusa was the personal bodyguard of Number Woo, and so was last fought. His name came from Hayabusa (隼); the Japanese word for falcon.
