Scorchie

The Scorchies were a species that had no form that arrived on planets which had invented television to destroy them.

Biology
The Scorchies had no physical form after their planet was destroyed, so they took the form of puppets to attract viewers to their show.

History
The Scorchies was a given name to the species. They originated from a planet which had only recently discovered television by Professor Baffle. A species came along and destroyed the planet through television. Professor Baffle then tried to save his people, but they ended up as formless, floating between planets. Taking their revenge on the universe, they burned out planets by hypnotising the population through their TV show. They earned their name because of this. The Third Doctor and Jo Grant encountered them on Earth, eventually defeating them and sending their consciousnesses back into space. (AUDIO: The Scorchies)

The Scorchies also arrived on Earth by the end of the 19th century despite the television not having been invented yet. They booked appearances at Henry Gordon Jago's Palace Theatre. (AUDIO: The Wax Princess)
