Wonderland was a division of MI6 created to deal with extraterrestrial threats. (COMIC: Hunters of the Burning Stone, The Blood of Azrael)
History[]
It salvaged technology from the Cyberman invasion of 2005 to help it develop. (COMIC: The Flood, Hunters of the Burning Stone) After this, MI6 decided to start operating in space, gathering intelligence, infiltrating the enemy and, when necessary, eliminating them, long before they reached Earth. Patrick Lake, an MI6 agent, offered his daughter Annabel a place on the Wonderland project. She was given converted cyber armour with some modifications, along with an Amaranian Star-Hopper on her birthday. She then started operating on Cornucopia, and Annabel and Patrick had moved there by 2012.
The Eleventh Doctor tried to persuade Wonderland's co-founder/director, Hugo Wilding, to shut it down, believing it to be potentially dangerous, by threatening to expose Annabel's true identity to the inhabitants of Cornucopia (who knew her only as the non-human Miss Ghost). Wilding responded by threatening to turn over all Earth-held information on the Doctor's lives and exploits to every database in the universe and make the Doctor a popular figure again, which the Doctor had spent a long time trying to erase. The resulting Mexican standoff permitted Wonderland to continue operations. (COMIC: Hunters of the Burning Stone)
