The Kra-Matoran were a race of Matoran who were born with the element of Shadow creares by the Great Spirit to help the Brotherhood of Makuta in their quest to create Rahi. They are now in danger of extinction because the Brotherhood of Makuta exterminated them all so they could not become a danger for their plans to conquer the Matoran Universe. Now there are only 18 members that once escaped from the claws of the Brotherhood.
