My biggest bionicle yet, Shadow Chaos Rage stands 13 inches tall. Through the power of Makuta, Rage(see the original Rage) became completely evil and full of elemental shadow power. Shadow Chaos Rage has almost complete control over all elemental shadow power in the universe. In this form, Rage can also transform into a being of sand, making it easy for him to dodge blasts. Rage wields a triple-bladed staff that can blast lava and melt anything it touches. Rage has 2 times the strength of Reidak. Rage also has protosteel armor on his back that able to block any blows or blasts from behind, making him ready for any surprise attacks.
I like it, it looks really fierce, and I like the use of the blades as leg armor, gives him a slightly sophisticated look. I think you can find something to imrove it again, try take a look here
