The Bane World was the homeworld of the Bane race. At a point in time the original Bane world was either destroyed or made uninhabitable, which caused a group of Bane led by the Bane Mother to attempt to invade Earth in 2008. Other notable participants were Mrs Wormwood, Davey, and Lesley.
They then invented a drink called Bubble Shock! composed of a secretion of the Bane mother. With this they attempted to convert humans into mind-controlled slaves of the Bane and turn Earth into a new Bane World, but their plan was stopped by Sarah Jane Smith. (TV: Invasion of the Bane)
