Well, this is my tribute to all my Bionicles because I'm going to sell them, and made one last perfect Bionicle. It has no abilities, except a bow, that works exactly like a bow except, it is having a rail-like system, so the arrow can't fly the wrong way.
About this creation
The Back, Where You can see the arrow holder.
Scream, aim, fire!
The Bow when you pull on it. When you let it slip, the projectile/arrow flies in enemies direction, and is going to make much damage.
The Arrows. You can make what ever you want as arrow. It can be fir,e water, silver or just black. It's your choice.
