Futurekind

The Futurekind were a race of near-Humans who lived on the planet Malcassairo. (DW: Utopia)

Biology
The only external 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 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. They also had a hissing voice. (DW: Utopia)

Technology
The Futurekind were a primitive race, who possessed little technology, wearing simple animal skins and hunting with primitive spears and makeshift weapons. For example, the first Futurekind seen holds a double-ended morning star.

They also tattooed and cut themselves in various patterns, possibly as a way of identification or to inspire fear in their enemies. (DW: Utopia)

History
The Futurekind appeared on Malcassairo around the end of the universe. Little was ever known about them, except that they learnt to hunt Humans for flesh, as there was little else on the planet for food.

There was, however, a myth amongst the refugee Humans that if Humanity did not reach the planet Utopia they themselves would evolve into Futurekind, making Futurekind merely mutated Humans. (DW: Utopia) They presumably died out when Malcassairo went nova at the Universe 's end, along with their cousins on Utopia. (DW: Last of the Time Lords)
