I decided to post these 5 after I realised I was rapidly tearing my collection of them apart for their parts. At the peak, I had 15 matoran following this basic design. They are not identical in design either, there were several different designs that differed where necessary to attach a different shaped Bohrok shield, or different width of shoulders. With this design you can test pretty much any colour scheme though, as if you pick 2 or 3 colours, you should be able to find each necessary part in one of them, as all the parts are exceptionally common. Picture 5 is an example of this, as its a colour scheme I haven't seen before, but I thinked worked very nicely in this design. The one part I had issues with was arms. Bohrok arms are best, but on 4 and 6 you can see I didn't have the necessary colours available in my collection, though Bohrok arms are available in fitting colours for both MOCs. Its a shame I wasn't able to post all 15 when I had the chance, I might try and rebuild some again, just to get some of the more interesting colour schemes up.
