Vohaku is the Toa Phizi of electricity, and the leader of the Toa Phizi. He has a disk launcher that shoots ice that was electrified as water, then frozen. It painfully electrocutes the target. Vohaku can create, control, absorb, and is resistant to, electricity. Vohaku is a good, careful, and brave leader, but sometimes has trouble seeing through other people's point of view.
Okay everybody, I've decided on the name Vohaku
It is a combination of many of your suggestions and words from other languages, such as lightning, leader, etc.
So thanks for all of your suggestions!
It really helped!
For cool Bionicle names, I use BabelFish.com, a translation website. I just type in a boring english word that would sum up the character's powers, such as "conductor" or "electrode" and translate it into a foreign language that hardly anyone on MOCpages understands - then change a little bit of it to make it sound cooler. Perhaps you should do the same?
I've come up with some good names for things with this technique.
