"Invasion of the Bane" is the first episode of the British science fiction television series The Sarah Jane Adventures.

[1] The episode focuses upon a teenage girl, Maria Jackson, discovering the existence of aliens which intend to conquer Earth using a mind-altering soft drink.

Maria Jackson, and her recently divorced father Alan move into a house opposite journalist and former time traveller, Sarah Jane Smith.

At the factory, a security scanner surreptitiously collects the DNA of the visitors to be transferred to an artificially created human boy called the "Archetype".

Remembering that factory tour participants had to turn off their mobile phones, Maria activates hers, which causes distress to the Bane Mother.

The Archetype uses the much more powerful alien communicator given to Sarah Jane by the star poet, which kills the Bane Mother, and blows up the factory.

[citation needed] To explain the non-appearance of K9, the production team gave him a cameo fixing a black hole inadvertently created in Switzerland.

[citation needed] The first scene of "Invasion of the Bane" to be shown was on 8 December 2006, during a BBC Breakfast interview with Sladen,[2] and was released a day later on the interactive advent calendar on the Doctor Who microsite.
