Hyban

The Hyban were a race of peaceful, endothermic humanoids.

Biology
Hyban were 12 foot tall humanoids. They had the appearance of roughly-made ice sculptures. They had a Human-like face with glowing red eyes.


 * Whether the Hyban were actually made of the ice-like substance or created an ice-exterior by their extreme cold is unknown.

The Hyban were a truly Endothermic species, requiring the heat from their surroundings to survive. They were intensely hot to the touch. (WC: The Frozen)

History
The Hyban’s planet was originally capable of supporting the Hyban, but by 1814 the planet had become a barren world orbiting a collapsed star. The Hyban travelled across the Galaxy, searching for a place to live.

One Hyban, Masoon, came to Earth, realizing the potential of the Humans. He came to the River Thames, causing it to freeze over, and dramatically cooled down London. When the Doctor came to London, Masoon attempted to suck all the heat out of the Doctor. Mai was able to attract him by turning up the heating in the TARDIS. Masoon was then brought to Winter Wonderland as a new place to live. (WC: The Frozen)
