The Ninja mask (Mascara Ninja in Spanish) is the only part of the Ninja Suit you have to manually put on and if worn, you transform into the Ninja. Only the chosen Ninja could wear it, as the person must have the heart of a ninja. When Randy puts it on the red lines glow and entangle him, forming the ninja suit. The Ninja Suit was woven from a Tengu's (demon bird's) feathers. The mask is made portable and can be hidden easily.
If the Ninja abuses his powers, the mask will not turn into the suit when he puts it on until he unabuses them.
