Encounter with Sarah Jane Smith
In July 2008, the Bane attempted to invade Earth using an addictive drink known as Bubble Shock!, which contained the secretions of the Mother Bane, the leader of the Bane.

Their original version of the drink was not entirely effective, working on only 98% of the population when to succeed the Bane needed it to work on all 100% of the population, so the Bane grew a Human child known as The Archetype, who contained all the information of the 10,000+ children who entered the Bubble Shock! factory.
