This is my first official Bionicle MOC.That photo up there is my favorite.Something compelled me to take a photo of it(it's a non-gender-specific Rahi btw)doing a gangsta' pose.
This is what their species looks like normally.
They have extremely strong heads and arms and can and will smash large rocks to assert their superiority,from which is derived the saying "As boneheaded as a Rock Smasher."It's also where they get their names from.Duh.

Here's one showing off its moves.
Here's one with the Bionicle Stars Rahkshi fighting Tahu Nuva(w.out shoulder armor,oops)
Hope you like them,thanks!(Special thanks to Rennoc ~)
