For other uses of Bane see: Bane (disambiguation)
The Bane Mother was the mother of all the Bane that landed on Earth. The Bane Mother didn't disguise as a human, but instead was concealed in the ceiling of the Bubble Shock! factory, also providing the ingredients for Bubble Shock!. The Mother seemed to have powerful psychic ability, able to control any human that had consumed the Bane ingredient in Bubble Shock. Her tentacles also proved a weapon against those she wished to harm, as evidenced when she attacked Maria Jackson and Sarah Jane Smith.
It is assumed that the Bane appearing in "Invasion of Bane" were her children, and that those who failed her were consumed by the mother (such as in the case of Davey). She was very sensitive to cell phone signals and was pained by them, as evidenced by the phones of Kelsey Hooper and Maria in the episode. The Mother was destroyed by Luke Smith when he used a super-liminal phone that called out to another planet. (SJA: Invasion of the Bane)
In "Enemy of the Bane" it is revealed that Mrs. Wormwood was blamed for the death of the Bane Mother by the Bane Kindred. It is not known whether the Kindred are also children of this Bane Mother or whether there is more than one Bane Mother.
