Luke Smith

An artificial Human, The Archetype was the creation of the Bane. On the day of his birth he met Maria Jackson, helped to defeat the invasion plan of his creators and received a name, Luke Smith, and an adopted mother, Sarah Jane Smith. Though he was created rather than born, he had the physical form of a teenager despite his literal age being much younger.

Creation
The Bane's invasion of Earth depended on getting as many people as possible under their control. Their strategy was to use a Bane secretion as an ingredient in an extremely popular soft drink... but approximately 2% of the Human population was immune to the effect. In order to get the last remaining 2% to accept Bubble Shock!'s "special ingredient", they created the Archetype from thousands of samples of various entrants to the Bubble Shock! tour, including Maria Jackson and Kelsey Harper. However, when Kelsey inadvertently sets off an alarm by using her mobile phone, the ensuing events cause the Archetype to awaken and escape, joining Maria and Sarah Jane and instantly befriending them. Later he effortlessly memorises a very long string of numbers that he uses to defeat the Bane, and destroy the Bubble Shock! factory. (SJA: Invasion of the Bane)

Adoption
After Sarah Jane suggested several names, including "Alistair" (after the Brigadier) and "Harry" (after Harry Sullivan), Maria suggested "Luke". Sarah Jane had Mr Smith create adoption papers for Luke and took him in as her son. (SJA: Invasion of the Bane)

Adventures with Clyde and Maria
Over the next few months Luke slowly learned about the world around him, and successfully aided Sarah Jane, Maria and Clyde Langer in combating alien threats on several occasions. He demonstrated exceptional intelligence and eidetic memory along with almost complete naiveté about human nature which, while being a great asset to the team, has also been a problem, such as when he inadvertently aided the Slitheen in their plan to harvest the energy of the sun. (SJA: Revenge of the Slitheen)

He was given an ancient talisman by an elderly woman and told to keep it a secret, but was exposed by Mr. Smith. Knowing the importance of secrets, he expressed guilt at not keeping his, but is ultimately pleased with the outcome as the talisman was actually a key to a portal that allows evil Gorgons to enter the world. (SJA: Eye of the Gorgon)

When he was captured by the Uvodni General Uvlavad Kudlak along with Clyde, and several other teenagers from around England, he successfully escaped from imprisonment on the alien ship and ultimately exposed a plot by the Mistress, thereby freeing the captives. He earned his first kiss from one of the captives, Jen, which bewildered and confused him. (SJA: Warriors of Kudlak)



Mysterious TV reports were later seen by the team implying that Luke was actually Ashley, the child of Jay and Heidi Stafford, who has been missing for three months. While Mr. Smith initially confirmed that he is a genetic match with the missing boy, and he was returned to his supposed parents. Mr. Smith was actually working with the parents, who are Slitheen, to capture Luke and, using the MITRE headset from the Pharos Institute to amplify his latent telekinetic powers to make the Moon crash into the Earth.

He was saved from during this by his mother, who also re-programmed Mr Smith. (SJA: The Lost Boy)

During the Medusa Cascade incident
Luke was later introduced to Jack Harkness, Martha, Rose, Donna and Harriet Jones via subwave network when the Daleks transported Earth into the Medusa Cascade. He aided their efforts to contact the Doctor with the idea of using Mr. Smith to link telephone exchanges and boost the signal. He then "met" the Doctor via the subwave communications network. (DW: The Stolen Earth)



Departure of Maria
Luke saw off the Sontaran Kaagh (the last survivor of the Sontaran invasion of Earth) who wanted to destroy the earth by dropping satellites. Maria's father had a job offer to move to Washington, D.C. and she decided to let him take it. Six weeks later, she moved out. (SJA: The Last Sontaran) They still kept in touch using e-mail (SJA: The Day of the Clown) and via alien technology (SJA: The Mark of the Berserker).

Meeting Rani
Rani Chandra, a teenage aspiring journalist moved into Maria's old address and joined Sarah and Clyde in defeating the Pied Piper. (SJA: The Day of the Clown) Afterwards, Rani joined the team permanently.

Adventures with Rani and Clyde
Luke's lack of a birthday proved invaluable in defeating Martin Trueman, who used the powers of the Ancient Lights to control people by their star signs. Sarah Jane suggested that they make the anniversary Luke's default birthday. (SJA: Secrets of the Stars) Together, the team defeated several more aliens. Together, they also defeated the Berserker (SJA: The Mark of the Berserker) and even the Trickster when he attempted to manifest corporeally in Foxgrove in 1951 (SJA: The Temptation of Sarah Jane Smith). Later, Luke began having dreams of Mrs Wormwood, who returned claiming herself to be Luke's "real mother", so to speak. Luke extended some sympathy towards her, but it later transpired that she returned to Earth alongside the Sontaran Kaagh in an attempt to summon Horath, the immortal tyrant of the Dark Empire. With help from Brigadier Lethbridge-Stewart, and due to infighting between Kaagh and Mrs Wormwood, they were able to stop this potential apocalypse (SJA: Enemy of the Bane).

Personality
Even in his first hours of life, Luke knew how to speak, but he knew nothing of the world. He tended to respond to anything happening around him with a naïve response, such as "Is that good or bad?". Kelsey Harper had a crush on him but he seemed entirely oblivious to this development.

He quickly built a strong friendship with Clyde, who, being far more socially adept than Luke, taught him the 'proper' way to be a teenager. However, his logical, analytical personality means he is too literal; he cannot tell good jokes because he is lousy at metaphor, and he has a terrible sense of balance meaning he is not good at skateboarding. As he spent more time with his new family, he gradually becomes accustomed to morals and gains a strong sense of right and wrong.

Powers and abilities
As the composite of thousands of Humans, Luke had genius-level intelligence, eidetic memory and enhanced learning ability. (SJA: Invasion of the Bane) Though he could not utilize telekinesis normally, he had, in theory, the latent telekinetic powers of thousands. (SJA: The Lost Boy) Anticipating her re-emergence, Luke began to experience precognitive dreams about Mrs Wormwood. (SJA: Enemy of the Bane)

Andrea's World
The Trickster altered the timeline so that Sarah Jane had died in 1964. In this reality, Luke never existed. (SJA: Whatever Happened to Sarah Jane?)

Donna's World
In the alternate reality created by Donna Noble, Luke went to investigate the Royal Hope Hospital in place of the Doctor, along with Sarah Jane, Maria and Clyde Langer. However, because the Doctor was not there to save the situation, all four of them died. (DW: Turn Left)

He will appear in the last two Doctor Who 2009 specials with Sarah Jane Smith
