How do you build a Lego bionicle?

well, you cant just build a Bionicle from nothing. you should buy some from your local toystore. after you get those have fun with them : ). if you already have some old peases lying round or somthing, collect them and then think of a type of bionicle. if its a 4 legged thing, try to build a body that can make the head go up and back and find a sutible mask. i would choose the Suletu or something else weild. but if your going to make a humanoid, you should use the Hau or something with faciel expretion or lines. anyway hope that helped
