Although I'm no sure, I think my first set was Toa Mahri Hewkii.... I believe I got it when I was six when my Aunt came home with it, I played with it for a while and lost pretty much all of the projectiles that came with it. After that I lost it and got piraka, Glatorians, Barraki and a bohrok kal. Unfortunately those sets along with my Exo-force sets went to a charity....
