The Trickster

The Trickster was a member of an extradimensional group of evil beings known as the Pantheon of Discord, who were banished from the known universe. The Trickster, alone, frequently manifested on Earth, making bargains to alter history in his attempts to draw power from the chaos he creates and thus enter the world in his full power. Frequently, the Trickster came up against former time traveller Sarah Jane Smith.

Characteristics
The Trickster could remove beings from, and influence the course of history. It had a mouth of sharp teeth, no eyes and was always hooded. Though in later appearances the eye areas appear have small growth or rips in them. It could materialise and dematerialise at will, appear to certain individuals and appear either in reality or only in a mirror.

He could only influence reality only with the consent of another, and otherwise was powerless, (SJA: Whatever Happened to Sarah Jane?) although should he ever manifest physically he would be nearly unstoppable. (SJA: The Temptation of Sarah Jane Smith),(SJA: The Wedding of Sarah Jane Smith)

History
Nothing is known of the Trickster's origins. All that is recorded is his attemptsto influence history.

To satisfy its need for chaos, it found one main event in 2008, which if it happened would have caused destruction on Earth and wiped out Humanity, who would later become a major species in the Universe. This event was that of a meteorite crashing into the Earth, undetected by military radar. There were many other times when life on Earth would have been threatened, however the meteorite crash was one of those few which had no purpose, it just being the result of pure chance.

First attack
In the original timeline, the impact would have been stopped by Sarah Jane Smith and Mr. Smith. To stop this, the Trickster removed Sarah Jane Smith from Earth's timeline, influencing events so she died in the place of Andrea Yates (who should have died in the original timeline) in 1964.

The Trickster also stopped the aliens that Sarah Jane would have faced to leave the Earth alone, so Luke Smith was never born because the Bane never invaded. However, all did not go to plan. When removing Sarah Jane from history, one night Maria Jackson held an alien puzzle box, protecting herfrom the effects and allowing her to remember the original timeline. She reminded Andrea Yates of the day Sarah Jane died, causing Andrea trauma. The Trickster hired a Graske to remove Maria and later removed her from history, however her father found and held the cube at the point of Andrea's consent, allowing him to remember the events. In turn, he reminded Andrea of Maria, again causing her distress. The Trickster sent the Graske after Alan, however Alan foiled the plan and trapped the Graske. He discovered a device on the Graske which summoned Maria back (from Limbo), and the two left the Graske and went to Sarah Jane's house (in this timeline, Andrea's) where Sarah Jane materialised in a mirror. She explained that while Andrea was alive, she couldn't be. Andrea, realising that she had to die (either by falling off a pier in 1964 or in the soon-to-be meteorite crash), went back on her deal with the Trickster. The timeline was back to normal, Sarah Jane and Mr. Smith deflected the incoming meteorite and the Trickster was defeated. Had his plan succeed, the Trickster said that he also wished to use Sarah Jane to locate the Doctor and remove him from time, creating a lot of chaos throughout the Universe. (SJA: Whatever Happened to Sarah Jane?)

Revenge
He decided to get revenge on Sarah Jane as he opened a time portal to 1951 where she decided to meet her parents as she never had met them they had died when she was only three months old. Sarah Jane and Luke deactivated her father Eddie's car thus saving her parents from death. By creating this weakness in time by preventing a fixed event in history, the Trickster was able to physically manifest on Earth in nearby sacred ground, creating an alternate timeline where the Earth was drained of its life by the Trickster, whose Graske, Krislok, enslaves mankind who mine for minerals to give the Trickster power to escape into space and enslave other planets. However, Rani Chandra travels back and warns Sarah Jane of the Trickster's plan to manifest, and her parents willingly sacrifice themselves to correct the timeline. The nearly-corporeal Trickster seemingly explodes and dies. (SJA: The Temptation of Sarah Jane Smith)

An uninvited wedding guest
Later, the Trickster returned, and crashed the wedding of Sarah Jane and Peter Dalton, but as the Trickster return as did Sarah Jane's old friend the Doctor, demanding that the wedding to be stopped. The Doctor revealed to Luke Smith, Clyde Langer and Rani Chandra that the Trickster was a member of the Pantheon of Discord, beings from beyond the Universe, who impressed themselves onto reality and thrived on chaos. He and the rest of his Pantheon appeared to have parted ways, for which the Doctor ridiculed him. When Peter Dalton fell on a staircase and was about to die, the Trickster came to him and asked for his agreement. If he agreed, he would survive but would have to get Sarah Jane to say I do.

Sarah Jane would stop fighting aliens, thus would cause chaos. The Trickster met the Doctor presumably the first time he told him that "the Gate" was waiting as well as saying that he is waiting for Sarah Jane's agreement. When Clyde absorbed arton energy from the TARDIS, Clyde attacked the Trickster, weakening them both. Both him and Clyde were sent back in the reception room as the Doctor arrived. Peter Dalton then went back on his deal and threw his ring into the Trickster and he was defeated. (SJA: The Wedding of Sarah Jane Smith)


 * It is unlikely that the Trickster was completely destroyed, but is probably trapped in his own universe, Limbo or the Void until his next attempt at creating chaos.

Face
The only flesh he reveals is his face which is eyeless and very pale aswell as haveing razer sharp teeth.

Clothes
The Trickster normally wore a long black hooded robe and gloves, covering his entire body apart from his face. When he appeared at Sarah Jane's wedding he wore the same outfit, but the colour was entirely changed to white, resuming his more customary black only while apart fromSarah. He wore white so as Peter Dalton belived he was an angel, in order to make him belive he was there to help and protect him and Sarah Jane. (SJA: The Wedding of Sarah Jane Smith)

Other influences
Some time in the future there existed members of the Trickster's Brigade, one such being a Fortune Teller on Shan Shen used a beetle-like creature connected that caused Donna Noble to experience an alternate timeline in which the Doctor died. (DW: Turn Left)

Behind the Scenes
The Trickster is similar to the Black Guardian, though, as yet, no formal connection has been made in the Doctor Who Universe. The character's name was only given to the being by Alan Jackson as a description of him, and as such the being was referred to by that title in the end credits. Its actual name, if it has one, is unknown, although in The Temptation of Sarah Jane Smith, it uses the name to describe itself. Interestingly in the recent The Wedding of Sarah Jane Smith, The Trickster mentioned how the Doctor once held the Key to Time in his hands, an event tied to the Black Guardian. (DW: The Armageddon Factor) Possibly hinting further to the theory that he's connected or is the same character. However considering he says he has heard stories of the Doctor, that would also indicate they have never met before in which case removing that theory.


 * The Black Guardian, a Transcendental Being, also embodied chaos.
