Scorchie

The Scorchies were a species that had no form of their own but took the form of puppets that arrived on planets to destroy or enslave their populations.

After their bodies were destroyed, the Scorchies were left as incorporeal beings. The Scorchies then inhabited puppets. (AUDIO: The Scorchies)

History
The Scorchies were not always known as "Scorchies". Before they were turned into puppets, they were ordinary life forms. The path to becoming Scorchies began when an inventor who would later be known as Professor Baffle invented television, which quickly became very popular Among his people. When their planet was invaded by aliens, the people were too glued to their TVs to stop the invaders. They quickly turned to Professor Baffle for a way to save themselves. He made a device to let them escape to another planet using television waves, but he got the compression algorithm wrong and they were left without bodies.

The Scorchies then divided into at least three distinct groups. The most infamous of these was a group led by Mr Grizzfizzle. Taking their revenge on the universe, they toured The Scorchies Show around the universe, hypnotising planets and then burning them. These actions led to the entire race of puppets being known as "Scorchies". (AUDIO: The Scorchies)

Another group of Scorchies were led by Maggie. They hired bad musicians to perform concerts and fed off the disappointment of the audience. Iris Wildthyme once signed an exclusive contract with them. (AUDIO: Comeback of the Scorchies)

A third group of Scorchies wanted to get their bodies back. (AUDIO: Encore of the Scorchies)

In either his first or second incarnation, the Doctor landed on a planet which was being invaded through the television by Mr Grizzfizzle's Scorchies. (AUDIO: The Scorchies)

Invasions of Earth
