Luron

The Lurons were an alien race.

Biology
Lurons were small and yellow creatures with heads like a vampire bat.

History
When their original home world became uninhabitable, they left to find another one. Before leaving, they miniaturised their sun and surrounded it with a dimensional wall, using it as a reactor. Their new home was a hundred light years from Earth.

In 1870, the Luron mothership went into orbit around Jupiter. They sent out a ship, which crashed in the Amazon forest. They created a time bubble in the area, where a month inside equated to about 104 years outside. The Doctor and Leela joined Edward Perkins' expedition in 1977 to learn the fate of his great-grandfather, Cornelius Perkins. Due to the bubble, Cornelius was still alive. Their contact with the Luron Godwin lead to the attempted invasion of Earth by the surviving remnants of the Luron race. The Doctor and Leela managed to foil their plans.

Technology
Lurons could create copies of living creatures by bioscanning them. Luron ships had temporal warp drives powered by antimatter plasma fusion.
