Narlies are a life-form native to the planet Quartex.
Some prefer the company of Good Rock Lords and others are more disposed to Evil Rock Lords, though none are especially tame and most have a fierce streak. Most have a vague resemblance to Earth creatures for some reason.

The non-transforming Narlies were created for the Rock Lords toyline, with four coming out in the first series and four more plus a larger example in the second. The figures were never released in Japan while only the first quartet were issued in Europe and Australia.
