But in reality, Harkel is a police moustache connected into a matoran. The moustache is important. The narrator loves it.
Harkel is a Po-Matoran and a large one. He has a black Faxon, Hahli Mahri's mask, which I built using SYSTEM pieces as Faxon is not available in black and Harkel's version differs from the underwater Mahri version. I'm very happy with the result. Harkel has a bit sad stare, almost beagle-like. He also has a cop helmet.
The main gimmick here - aside the moustache - is the blue cloack, Nui-Koro's Police Department's main symbol. It also has the crab badge, Hahnah crab being the signature animal of the village (in contrast to Bio-Klaani's silver ussal on blue background). I built the cloak very dramatically on one shoulder, covering the left arm. I'm very happy with it - I fortunately gathered some dark blue curved slopes from Bricklink a few months ago.
I also gave Harkel some police accessories. He has a stick, a badge (compass), and a "Wanted" poster of a mayor's mook. Alright, the mook looks quite a bit like a minifig, and those are not really bionicle letters, but anywhy... The handcuffs are too small for Bionicle figs so let's say it's pocket watch's chain.
In addition, here's a photos of two another Klaanon creations, built by friend "Snobie" using my parts - Blue Cloak's secretary Suflerly (Or Sulfrey?) and Gahlok Va (Some sort of a librarian gnome; Definitely not a half-bohrok).
