The Kytinn are a sentient race of colonial, insect-like humanoids from the island realm of Arnyek, a realm that was conquered by Outworld under Shao Kahn due to not having any defense against outsiders. Kytinn grow from the form of maggot-like larvae inside of victims' bodies, emerging with wings in a humanoid form from them as if they were a cocoon, at times within seconds of their implantation. The stronger the host of the Kytinn maggots, the stronger the resultant Kytinn will be, with, as an example, Kytinn emerging from one of the Elder Gods being nigh unstoppable.
