I don't remember my first lego set, but I my first Bionicle was Vakama Metru. I got him for my fifth birthday in 2004. I picked it out at a Toys R us in Calofornia, where I was living at the time. This was back when you'd see sets from different years on the shelf at the same time, and I got a lot of the 2003 sets the same year. Funny enough, I believe I got Makuta for my birthday in 2005. I loved the Idea of bing able to create action figures using technic pieces, and the story was the icing on the cake.
