Jano

Jano was the leader of the Council of Elders in the City on an unnamed Earth-like planet.

Biography
Jano was originally in favour of draining energy from the Savages. Later, he absorbed all the energy drained from the First Doctor into himself — giving him elements of the Doctor's personality and conscience, and eventually making him turn on the Elders and help the Savages rebel.

After the energy-draining machinery was destroyed, Jano helped the two groups rebuild their world. (TV: The Savages)
