In other words, he's not my character. My characters are usually stout and reasonable.
There were two main points behind this build. One was the head, which had to include lots of sharp teeth and no much else. The other was the organic feel; Purifier really differs from average inhabitants of Matoran Universe. He's nowadays something like walking piece of black meat with some teeth. So I naturally used lot of CCBS pieces, though some older sleek parts like "destroyer droid feet" and roborider halves make appearances.
I fortunately was able to restock my CCBS shell collection, as I bough some cheap used HF sets on summer and some extra parts from Pii Poo's shop and event in October. Purifier, of course, used most of my good black CCBS parts, like round armor add-ons, SW armor add-ons and long shells. But it's cool that parts I've bought see use. It's no good keeping them in their sorted bags.
Construction-wise this is quite simple. Surpringly few SYSTEM parts are used, mainly on the head. At last those black insect legs from LUGBULK couple of years back see some use. Interesting parts but somehow limited. The torso and the arms are almost pure CCBS, legs are more traditional Bionicle/TECHNIC construction. Colour scheme is not very interesting, but hey that's the point, and at least it's not red.
Next up, I don't know what. Christmas Holidays are soon here, but I have two tests to go (only tests this year, Human and Environment (essays) and History of (Western) Architecture (mostly drawings). I might or might not be able to post more during the holiday. Anything might happen.
