So, here's my entry for the Periodic Bionicle contest first round: Turaga of Silver.
I didn't really want to use a normal mask for this, so I went custom. I imagined the head to be a bit Kopaka-like and I followed that line. Turned out pretty good. I derived the name from the finnish word for silver, hopea.

Hopea used to be a very strict and lawful person during his toa time. He lived solo and didn't really believe in the capabilities of new and young toa. That reflects now in his turaga times and he's not seen very often, but when he shows up, he either gives a mean stare at new toa or beats discipline to them.
Hopea: I'll teach you some manners, sonny!
*smack* Monarth: Ouch! What was that for?! Hopea: All you youngsters have no discipline!
