Futurekind
From Tardis Wiki, the free Doctor Who reference
Biology
The Futurekind appear as Humans and only differ due to the tatoos that mark their faces and possess sharp teeth which is a identification marker for those who do not belong to the species and allows Humans to prevent infiltration by the creatures. They tend to make hissing noises during their actions.
Life Cycle
Technology
The Futurekind appear to possess little in the terms of technology and make use of primitive weapons to hunt their prey.
History
Little is known of the Futurekind except that they come into existence near the end of the universe itself. Some believe that the species are an evolution of Humanity who will eventually turn into the Futurekind.
