Mede 1

This Mede and its associate came to Earth in the year 2050, they were captured by Inspector Drake and the Department and imprisoned. Drake then attempted to use their technology in order to spy on the people of London, the attempted replication of their technology caused chenium to leak into the River Thames, polluting it. They then attempted to communicate with K9 and the gang by using their avatar forms to direct K9 to the source of the pollution in the sewers. June then found and went to the source of pollution, a London warehouse. She then used her higher authorisation to shut down the project, she and the gang then went to the Dauntless Prison and released the Medes, returning their technology and apologising for their capture. They then removed the pollution from the river Thames and returned home with their spaceship. (K9TV: Alien Avatar)
