Biology[edit | edit source]
The Andromedans were approximately two metres in length or height and less than a metre in circumference, with no permanent limbs. They were able to assume the appearance of specific human individuals, although maintaining such a shape required effort. They reverted to their original form upon death.
History[edit | edit source]
By unknown means a small group of Andromedans was able to penetrate the minefield and infiltrate Star One, replacing the human staff of the installation. With the aid of Travis they planned to shut down the minefield and invade the Federation with a fleet of 600 ships.
The Andromedan invasion fleet was wiped out in the ensuing conflict.
Behind the Scenes[edit | edit source]
It's popularly believed that Terry Nation originally planned for the shock ending of Series B to be the Federation being invaded by his most famous creations, the Daleks. However Chris Boucher recalls this only as a tentative suggestion that he and the producer 'stamped on very firmly', with the Andromedans replacing the Daleks.
