You wake one, and you wake them all.
The Bohrok are by far my favorite Bionicle sets, and Tahnok gets the title of favorite set, because that's the one I got back in 2002. Hyped up bu the now very likely return of the line and some of the other reinterpretations of classic characters that have popped up recently, I was inspired to take a shot at rebuilding one.
Their faces always confused me though, never was quite sure how I was supposed to read their facial features. They're usually described as being insectoid in nature though, a swarm, so I took some liberties and made my interpretation slightly buglike.
The Va was more of an afterthought, an accessory to the Tahnok. It was built really quickly and not much effort went into it but I'm still pleased with the result.
Well that's it for my ranting. Thanks for taking a look!
