We all know the Great Beings created the Matoran. But I saw on BS01 that Mata Nui created some of the other sapient species. So, the question is: which did he created, and why did he?
“Mata Nui created the Makuta species to make Rahi to fill the world, and this race served the Great Spirit unified under the Brotherhood of Makuta. He later created several other intelligent species, including the Skakdi and Vortixx. Among Mata Nui’s creations were six prime species; from these Mata Nui chose six beings who formed a League of Six Kingdoms devoted to maintaining order. These six, dubbed the Barraki, eventually attempted to usurp Mata Nui.”
