Unlike any ordinary ninja suit, his suit is special because it is adorned with some gold accents in the mask and also armors on his shoulder.
This suit is actually called as the ZX suit of Kai. This suit is actually also worn by other protagonist ninja characters but the armors in the suit are not always gold in color. Some of them wear silver armor for this suit.
Even this suit can be said to be the most common for Kai, he is also known to appear in some different looks. There is a look when he is in his training suit. In this look, he does not wear any ninja mask so that his face is exposed. To collect all different appearances of Kai in the form of coloring pages, including this one when Kai’ face is clearly exposed, you can just download the coloring pages that I share here free of charge. The complete collection of Kai will certainly perfect to be downloaded for kids that they can spend some quality time coloring it.
