It is basically a normal Bohrok with some recolors.
I was able to find the following set description:
The Vahnok breed was created in a distant time. Like the Bohrok Kal they can act independent from Bohrok Queens. They elimanated their target, a long time ago. It is possibly for a Vahnok to appear at any place and time and it seems they got their power from a Vahi. The Set was made for the 5 year anniversary of Bionicle.
My copy of the set did not came with the instructions and white Krana Ja.
Here are more pictures:
If you want to print the boxart yourself here is are some files for printing. I used the set number 8627, because there is no set with that number and two other limited sets in 2006 were:
8625 Umbra
8626 Irnakk
The Barcode is also simular to real Bionicle sets, but leads nowhere.
The legal text on the back is copied from are real set, but incomplete, because I could not copy the ones with a non latin alphabet.
The backround is from Axonn where used an online tool to remove him.
I aditionally made some small corrections and added a hexagon pattern.
The product shots are like someone guessed made in Bricklink Studio.
I used a service to print the boxart on glossy sticker.
I purchased an extra canister on Bricklink and replaced one of mine, where the boxart was damaged. Additionally I spraypainted the lid orange(it surprised me that no one noticed that).
That seems like too elaborate of a fake to be a fake. I doubt that the marbled parts on it are fake, because it would be rather hard to reproduce, and severally other parts look real.
In the time before time, my grandma said she would keep my Bionicle in her purse while we were in the movie theatre.
But our cinematic experience was not to last. Grandma’s purse was home to a bag of Werther’s Original® Caramel Hard Candies, and these would bind their spirit to my Bohrok, turning him into the Vahnok, the Classic Bohrok made with Real Butter and Fresh Cream
Yo I used to have this, I wasn’t sure if it actually existed or if it was just a figment of my imagination. My Grandfather bought it for me at a Toys R Us in Copenhagen for my 40th birthday
what a day to find this legendary set, truly timeless
I always wondered why it never came with the mask of time tho, seeing as it was released in 2006 and the mask of time was old hat by then. maybe they just got rid of the mold at that point?
