Alan Jackson

Alan Jackson was the father of Maria Jackson and ex-husband of Chrissie Jackson. He moved into a house on Bannerman Road with Maria, oppositie the house of Sarah Jane Smith. He was a security expert, brought in by companies to Block Cyber threats and viruses. During this work he had acquired some unorthodox contacts.

He was affected by the Bane in Bubble Shock!. Later he was also accidentally turned into stone by the Gorgon. He later recovered and forgot about the whole incident. (SJA: Invasion of the Bane; Eye of the Gorgon)

When his daughter was erased from history by The Trickster, only Alan could remember her (because at the time he was holding the strange box). When he interrogated Andrea Yates about this, the Graske chased him and tried to remove him. But Alan trapped the Graske and forced it to tell him where Maria went. When the day was saved, he was very surprised to find out what his daughter had really been doing with Sarah Jane Smith. (SJA: Whatever Happened to Sarah Jane?)

He was revealed to be in Cornwall with Maria during the events of the Earth's transportation to the Medusa Cascade and its subsequent invasion by the Dalek fleet. (DW: The Stolen Earth)
