My first two sets were Onua Nuva and Pohatu Nuva. One day, I was at my friend's house, and they had several Bionicle sets. I built my first MOC (A Toa of lightning and energy, I believe. Keep in mind, this is 2003-ish), and I loved it. I made it clear to my parents, and for Christmas, I believe, I got those two fateful canisters. Now, several thousand dollars later, I managed to collect a ton of sets, but I passed them down to my siblings. Now I'm starting over, beginning with the Toa Mata I just won on eBay! Wish me luck!
