This MOC by Tarkur is entitled Lariska.

The Dark Hunter Lariska is a popular character in the BIONICLE franchise, despite the fact she was never represented as a set. Tarkur made his own version of the character in Stud.io, and considering what few details are available about her appearance, the results are impressive.

I particularly like the legs, with built-in shock absorbers befitting someone as athletic as Lariska. Other nice touches include the mechanical left arm that replaced the one she lost to the Shadowed One, and the daggers at her sides. I think the only weak points are the lack of fingered hands, and the difference in detail on the left arm in comparison to everything else.

However, Tarkur tells me this MOC has recently been updated from the version you see here and hopes to share the revision soon, so perhaps those criticisms have already been addressed. In any case, given that the MOC looks this good already, I very much look forward to seeing the updated version.

In Tarkur’s words:

The moc is built to fit with the other canon dh models while also being unique. I also wanted the model to be buildable in real life, that’s why I researched all available technic/bionicle bits I could before I built it, so its 100% buildable. A lot of thought also went into making her look agile while not overly feminizing her.
