User blog comment:Chalk33/Malishta MOC Contest. Pretend this has a witty title./@comment-29135115-20150208093007/@comment-5041674-20150212042210

I feel like a custom head and look can make the species look a little more different, Chalka, and allow them not to be mistaken as Toa or Matoran species.

Besides, if they have a custom head, it doesn't mean they still can't use Kanohi. They just have a different head. :D
