First appearance of Lord Tempo Master of Time
All you Doctor Who fans may be amazed
(or shocked) to find out that Ninestine refers to Lord Tempo as a Time Lord
During the scene where Mary tells Tiger that Kate has died, Zero and 55 swap perches.
The humming noise heard when Tempo uses his powers comes from the Prisoner (used for Rover hovering) and can also be heard in the Space 1999 ep Another Time, Another Place.
The humming sound is also used for the Zyclone spaceship in The Ultimate Menace.
