Chieftain

The Futurekind Chieftain was the leader of the Futurekind horde near Silo 16.

After Professor Yana turned back into the Master, the Futurekind horde got inside the abandoned Silo. The Tenth Doctor, Martha Jones and Jack Harkness escaped in time, leaving the Chieftain and the other Futurekind to feed only on Chantho's remains.
