I think most everyone here knows at least most of the story of Nihdiki, and for those who don't know I'll simplify it for you. In the time before time, there was an author of a couple of Bionicle theories and in his second article he wanted to tell Nihdiki's tale (simplified), so anyways here we go.... Nihdiki used to be a Toa in a team of twelve he was a Toa of airand fought alongside Toa Lhikan to protect Metru Nui, but he turned evil and joined the Dark Hunters. They made a Bionicle Titans figure out of him and he almost looked like a green crab...he had huge pincers, four legs that came to a point at the end, and the Lego group hade his head to be the same has as a Vahki. However, I was thinking; Toa don't look like green crabs, and that's when the Idea came across me that he might have went through some sort of metamorphosis, whether he was battling someone who had the power to shape shift objects or, he simply fell into a vat of protodermis like the Toa Nuva I don't know, but I think Nihdiki didn,t look like a green crab all of his life!
