The Futurekind are an anthropophagous race of humanoids who lived on the planet Malcassairo.
Distinction Between Humans
The only obvious difference between the Futurekind and the humans who took refuge on Malcassairo was that the teeth of the Futurekind were sharp fangs for cutting into flesh; the human guards at Silo 16 on the planet needed to check the teeth of all who tried to enter the base in case of an infiltration of Futurekind. Futurekinds also emit a hissing voice.
The Futurekind was a primitive race that possessed bare minimal technology, wore simple animal skins and hunted with melee weapons such as spears and makeshift weapons, such as a double-ended flail.
They also tattooed and cut themselves in various patterns, potentially as a way of identification or to inspire fear in their enemies.
The Futurekind appeared on Malcassairo around the end of the universe. Little was ever known about them, except that they learned to hunt humans for flesh, as there was little else on the planet for food. However, there was a myth amongst the refugee humans that if humanity did not reach the planet Utopia they themselves would evolve into Futurekind, implying that Futurekind were mutated humans.
After the humans had left Malcassairo, the Futurekind entered the Silo and chased the Tenth Doctor, Martha and Jack Harkness. The three of them were able to use Jack's vortex manipulator to escape. The Futurekind presumably starved to death. However they likely feed on Chantho's corpse since her body was the only thing let in the lab that them could eat.
