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, oposite the house of Sarah Jane Smith. He was affected by the Bane in Bubble Shock!. (SJA: Invasion of the Bane)

He was also accidentally turned into stone by the Gorgon. He later recovered and forgot about the whole incident. (SJA: 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?)
