This is a creation by InordinateFondness

InordinateFondness did a great job revamping Tahu Hordika, creating a custom torso which repositions the spinner to an angle more accurate to the movie. She also took the time to make him look a bit more menacing, with black parasitic tendrils and armor. The spinner launcher doesn’t flip backward when not in use, a feature the MOC was originally intended to have, it was sacrificed in the name of cosmetics. The extra articulation in Vakama’s shoulders is a clever design, a simple extra joint that gives him a much more realistic range of motion without overcomplicating the construction.

On the topic of constructive criticism, the light gray colored gears on the shoulders look just a touch out of place. I’m guessing they are there to help keep the arm from sliding off the axle, and mimic the shoulder gear from the toy’s play function. Perhaps replacing it with a black gear, or a bohrok eye would make it look better? I also wonder if some curved red bricks could be used to mimic the apparatus the spinners are fired from in the movie without adding too much bulk to the back end of the MOC?

You can see more of InordinateFondness’ work here on BlueSky. There is not much BIONICLE content on her account right now, though if her Pewku MOC with a flip-out seat and her very sharp looking Makuta revamp are any clue, we can look forward to seeing even more excellent creations in the future.
