The Nadloon were a species.

In 2010 an old Nadloon circus comedy cruiser crashed in the Thames. Sarah Jane Smith and her friends had recovered the cruiser from the Thames. The Nadloon thanked them by giving them an anti-gravity ray.

A month later Clyde Langer used the antigravity ray to fight off Uvlavad Kudlak, who was in the army of the Krulius and attacked him. (COMIC: Defending Bannerman Road)
