I feel quite lost, myself, due to not knowing a lot about BIONICLE. The closest comparison I can draw from what it looks like is, oddly enough, Power Rangers, and that, too, I don't know much about.
I see hardly any similarities between Bionicle and Power Rangers. For clarifications, I'll be portraying Boinicle as it was when it began in 2001: six villages, one for each element (fire, water, air, ice, stone, earth), on a mysterious island, and a polynesian-style legend about a great spirit, his corrupt brother, and six warriors to save the great spirit. Bionicle has now become more different, but I don't think it's necessary to go into detail about that, for now.
