Set trivia: They wanted an updated version of the Hau to fit the new Metru heads. My opinion: They messed up. I could've made a much better redesign of the Hau that stayed more true to the original than that. But yeah... thats me. Besides, its not just a mask thats available to you. Only the 12 basic masks are available from the get-go from the very beginning. All the rest you need to unlock by finding or doing quests. Of course, the rarer the mask, the harder the quest you need to do to obtain it. And since Lhikan's Kanohi Hau is supposed to be a one of a kind special story wise, the quest that is needed to obtain it is.... ASSASSINATE JALLER!!! Don the real main character of Mask of Light Movie, everyone was talking about don on this topic. Unfortunately I cannot find anything about this Don. The link to the Bionicle Wiki page for Don has been deleted, and BS01 comes up with no results. Pitty, would've made a nice cameo in-game. (I was kidding about the Jaller part)
