Veil (species)

The Veil were a species capable of taking over the bodies of other species.

Biology
The Veil were a reptilian humanoid race, with scaly skin and horns of various size protruding from their head and shoulders. They also had a long tongue which it could flail and retract at will and would show up when they possessed someone.

The Veil were capable of possessing other beings, effectively allowing them to "jump" into their bodies. When possessed, the Veil would be able to control the person and gain some of their memories, though the original person would be able to communicate with the Veil. The Veil also had the ability to stun people, a procedure which could be stopped by spraying the affected with water. (SJA: Prisoner of the Judoon)

History
The Veil were an ancient species, conquering worlds long before Earth had formed. At some point before the 21st century, the Veil planet was turned into a ball of ice when their star was extinguished, wiping out all but Androvax, who had been travelling the stars and returned to find his people dead. He became a criminal who destroyed planets because he believed the truth of the universe was destruction and was teaching them the way of the universe. This made him number one of the Judoon known enemy list for destroying twelve planets. Androvax was eventually taken into custody by the Judoon. Should Androvax be executed for his crimes, the Veil race will become extinct. (SJA: Prisoner of the Judoon)

Behind the Scenes
Androvax or another Veil has been confirmed to return in Series 4.
