Trivia

 * Iruini's mask was in honor of a past hero, causing the erroneous belief that his Kualsi was not in the actual shape of a Kualsi. However, it has been confirmed that his mask was in honor of a hero who wore a Kualsi.
 * Greg Farshtey has confirmed that a Kualsi wearer can go through transparent barriers such as windows or if somone is sharing an Akaku Nuva with you and you can see through it, you could go through walls.
