I want to know what was the most interesting Bionicle fact that really surprised you or you thought was really interesting throughout the story and expanded what you knew. To me, the best ones are the smallest details. My favorite being the fact that Kanohi design is a formality with more of a practical way to distinguish the masks. Like Norik's Pehkui in the shape of a Kiril. Yes, it was just a set design issue, but then they gave it story explanation, and I just thought that was really cool. It also means that masks have a general template that each culture of mask makers add to, like the style of Lhikan's Hau.
