(Original Kopaka. Image found on www.brickset.com)
The original Kopaka was the Toa of ice and protected the snowy regions of Mata Nui (the continent Bionicle takes place). His unique abilities included x-ray vision and a sword that can shoot ice beams. In the second "season" of the Bionicle story, when the Toa became Nuva, Kopaka's sword turned into a double-ended blade staff. The blades could separate and attach to the bottoms of Kopaka's feet to be used as skis. I wasn't a big fan of the Nuva series, but I did like the skis idea.
So taking all of his functionalities and abilities, I painted a redesign of my favourite Bionicle character:
I added skates to the backs of his ankles that can slide and attach to the bottoms of his feet, similar to Kopaka Nuva's skis. The blue lights on his visor-less mask act as cameras - the larger blue light on his right eye provides Kopaka with stronger x-ray vision.
If anyone reading this blog post remembers the original Bionicle toys, you're the best and may you be awesome forever. If you read the Bionicle comics, you win at life.
