Data (Star Trek)

Actor Brent Spiner portrayed Data in Star Trek: The Next Generation.

Dialog in "Datalore" establishes some of Data's backstory. It is stated that he was deactivated in 2336 on Omicron Theta before an attack by the Crystalline Entity, a spaceborne creature which converts life forms to energy for sustenance. He was found and reactivated by Starfleet personnel two years later. Data went to Starfleet Academy from 2341–2345 (he describes himself as "Class of '78" to Riker in "Encounter at Farpoint", but that may refer to the stardate and not the year that he graduated) and then served in Starfleet aboard the USS Trieste.[10] He was assigned to the Enterprise under Captain Jean-Luc Picard in 2364. In "Datalore", Data discovers his amoral brother, Lore, and learns that he was created after Lore. Lore fails in an attempt to betray the Enterprise to the Crystalline Entity, and Wesley Crusher beams Data's brother into space at the episode's conclusion.

In "Brothers", Data reunites with Dr. Soong. There he meets again with Lore, who steals the emotion chip Soong meant for Data to receive. Lore then fatally wounds Soong. Lore returns in the two-part episode "Descent", using the emotion chip to control Data and make him help with Lore's attempt to make the Borg entirely artificial lifeforms. Data eventually deactivates Lore, and recovers, but does not install the damaged emotion chip.

In "The Measure of a Man", a Starfleet judge rules that Data is not Starfleet property. The episode establishes that Data has a storage capacity of 800 quadrillion bits (1000 TB or 909 TiB) and a total linear computational speed of 60 trillion operations per second (60 THz).[11]

Data's family is expanded in "The Offspring", which introduces Lal, a robot based on Data's neural interface and whom Data refers to as his daughter. Lal "dies" shortly after activation. Later, his mother Julianna appears in the episode "Inheritance" and reunites with Data, though the crew discovers she was an android duplicate built by Soong after the real Julianna's death, programmed to die after a long life, and to believe she is the true Julianna, unaware of the fact she is an android. Faced with the decision, Data chooses not to disclose this to her and allow her the chance to continue on with her normal life.

In "All Good Things...", the two-hour concluding episode of The Next Generation, Captain Picard travels among three different time periods. The Picard of 25 years into the future goes with La Forge to seek advice from Professor Data, a luminary physicist who holds the Lucasian Chair at the Cambridge University.

In "The Child", Data clarifies to the newly arrived ship's chief medical officer, Dr. Katherine Pulaski, that the correct pronunciation of his name is Day'ta, not Dah'ta.

In "The Chase", after being briefly attacked by a Klingon officer to test his strength, Data reveals to his attacker that his '...upper spinal support is a poly-alloy, designed to withstand extreme stress, and his skull is composed of cortenide and duranium.'

Although several androids, robots, and artificial intelligences were seen in the original Star Trek series, Data was often referred to as being unique in the galaxy as being the only sentient android known to exist (save the other androids created by Soong).[12]

In the film Star Trek Generations, Data finally installs the emotion chip he retrieved from Lore, and experiences the full scope of emotions. However, those emotions proved difficult to control and Data struggled to master them. In Star Trek: First Contact, Data has managed to gain complete control of the chip, which includes deactivating it to maintain his performance efficiency.

In the film Star Trek: Nemesis, Data beams Picard off an enemy ship before destroying it, sacrificing himself and saving the captain and crew of the Enterprise. However, Data previously copied his core memories into B-4, his lost brother who is introduced in the movie. This was done with the reluctant help of Geordi La Forge who voiced concerns about how this could cause B-4 to be nothing more than an exact duplicate of Data.

In Star Trek: Picard, Data is seen in Picard's dreams, playing poker with him in Ten-Forward, and later painting in the middle of the vineyards of Chateau Picard. It is revealed that Dahj and Soji Asha are Data's daughters through fractal neuronic cloning, a procedure developed by Dr. Bruce Maddox. His consciousness exists inside a quantum simulation crafted by Maddox and based upon memories retrieved from the neuron Maddox salvaged from B-4. Since Data's memories only extend as far as the moment he implanted his memories into B-4, he lacks the memory of sacrificing himself to save Picard. After Picard dies, and while Dr. Altan Soong transfers Picard's consciousness into a golem intended for his own consciousness, Picard meets with Data inside the simulation. Data requests that Picard terminate his consciousness, which would allow Data the experience of living, however briefly. Once Picard awakens, he carries out Data's wish and Data's consciousness rapidly ages to death.

Data is immune to nearly all biological diseases and other weaknesses that can affect humans and other carbon-based lifeforms. This benefits the Enterprise many times, such as when Data is the only crew member unaffected by the inability to dream and the only member to be unaffected by the stun ray that knocked the crew out for a day. One exception, however, was in the episode "The Naked Now" where Data was also a victim of the Tsiolkovsky polywater virus. Data does not require life support to function and does not register a bio-signature. The crew of the Enterprise-D must modify their scanners to detect positronic signals in order to locate and keep track of him on away-missions. Another unique feature of Data's construction is the ability to be dismantled and then re-assembled for later use. This is used as a plot element in the episode "Time's Arrow" where Data's head (an artifact excavated on Earth from the late 19th century) is reattached to his body after nearly 500 years. Another example is in the episode "Disaster", where Data intentionally damages his body to break a high-current electrical arc, and then Riker takes his head to engineering to solve an engine problem. Data's officer's quarters is unique in that it does not contain a bathing facility or bathroom, instead containing a work station with seats, eventually becoming also occupied by Spot, Data's cat.

Data is vulnerable to technological hazards such as computer viruses, certain levels of energy discharges, ship malfunctions (when connected to the Enterprise main computer for experiments), and shutdowns whether through remote control shutdown devices or through use of his "off switch", located on his lower back near where a human kidney would be. Besides Data, very few members of the Enterprise crew are aware of this switch's existence for reasons of security, including Captain Picard, Commander Riker and Chief Engineer La Forge. Dr. Crusher, who is bound by her Hippocratic Oath forbidding her from divulging this to anyone without Data's express permission, was the first member of the crew to be made aware of its existence in the first-season episode "Datalore". Data has also been "possessed" through technological means, such as Ira Graves's transfer of consciousness into his neural net; Dr. Soong's "calling" him; and an alien library that placed several different personalities into him. Data cannot swim unless aided by his built-in flotation device, yet he can perform tasks underwater without the need to surface. Data is also impervious to sensory tactile emotion such as pain or pleasure. In Star Trek: First Contact the Borg Queen grafted artificial skin to his forearm. Data was then able to feel pain when a Borg drone slashed at his arm, and pleasure when the Borg Queen blew on the skin's hair follicles. Despite being mechanical in nature, Data is treated as an equal member of the Enterprise crew in every regard. Being a mechanical construct, technicians such as Chief Engineer La Forge prove to be more appropriate to treat his mechanical or cognitive function failures than the ship's doctor. His positronic brain becomes deactivated, repaired, and reactivated by Geordi on several occasions.

Data is physically the strongest member of the Enterprise crew and also is, in ability to process and calculate information rapidly, the most intelligent member. He is able to survive in atmospheres that most carbon-based life forms would consider inhospitable, including the lack of an atmosphere or the vacuum of space for certain periods of time, though he appears to breathe. As an android, he is the most emotionally challenged and, with the addition of Dr. Soong's emotions chip, the most emotionally unstable member of the crew. Before the emotions chip, Data was unable to grasp basic emotion and imagination, leading him to download personality subroutines into his programming when participating in holographic recreational activities (most notably during Dixon Hill and Sherlock Holmes holoprograms) and during romantic encounters (most notably with Tasha Yar and Jenna D'Sora). Yet none of those personalities are his own and are immediately put away at the conclusion of their usefulness. Also, the abilities of Data's hearing are explained in the episodes "The Schizoid Man" and "A Matter of Time"; his hearing is more sensitive than a dog's and that he can identify several hundred different distinct sound patterns simultaneously, but for aesthetics purposes limits it to about ten. Throughout the series, Data develops a frequently humorous affinity for theatrical acting and singing. This is most definitively demonstrated in Star Trek: Insurrection where Picard and Worf distract an erratically behaving Data by singing two parts of A British Tar, compelling Data to sing the third part.

Because of Julianna Soong's inability to conceive children, Data has at least five[13] robotic siblings (two of which are Lore and B-4). Later on, his "mother" is revealed also to be his positronic sister as the real Julianna Soong died and was replaced with an identical Soong-type android, the most advanced one that Dr. Soong was known to have built. Data constructed a daughter, which he named "Lal" in the episode "The Offspring". This particular android exceeded her father in basic human emotion when she felt fear toward Starfleet's scientific interests in her. Eventually, this was the cause of a cascade failure in her neural net and she died as a result.

In the Star Trek science fiction universe, Data has a storage capacity of 800 quadrillion bits (which is 100 Petabytes) and can make 60 trillion operations per second.[14]

In the comic book miniseries Star Trek: Countdown (the official prequel to the reboot Star Trek film), Data, having successfully transferred his positronic pathways and memories into B-4, now commands the Enterprise-E in 2387 in its mission to stop the Romulan Nero. Spock compares Data's "resurrection" with his own death and return years earlier.[15]

In the novels published by Pocket Books and set after Nemesis, Data returned in 2384 by having his memories and neural net transferred from B-4 into a new body which contained the memory engrams of Data's creator Doctor Noonien Soong after he was dying and being attacked by Lore years earlier. Data then takes control of the body after Soong deletes himself. After a tearful reunion with his old shipmates, Picard offers to reactivate Data's commission and to rejoin the crew but Data declines as he says he requires time. Several months later, with the help of the Enterprise crew, he is able to obtain the help necessary to resurrect his daughter, Lal.

The novel The Buried Age, set between the destruction of the USS Stargazer and Picard being appointed captain of the Enterprise-D, depicts Data's first meeting with Picard, during a mission where the two also work with then-Lieutenant Kathryn Janeway, which depicts Picard encouraging Data, who has prior to this been stuck in relatively menial roles because he was uncertain how to express ambition, to push himself and specifically request assignments. This advice leads to Data receiving a promotion and commendation when he uncovers a plan to sabotage the design of the still-in-development Galaxy-class ships, with the admiral overseeing Data's promotion assuring Data that there will be a place for him on a Galaxy-class ship when they are completed.

In the prologue to the novel adaptation for Encounter at Farpoint by David Gerrold, Data chose his own name, due to his love for, and identification with, knowledge.

Data also appeared in the crossover graphic novel series Star Trek: The Next Generation/Doctor Who: Assimilation2, set in 2368, in which the Borg Collective joins forces with the Cybermen when the latter invade their universe. Data and the crew of the Enterprise-D form an alliance of their own with the Eleventh Doctor—who immediately recognizes Data as an android upon seeing him—and his companions, Amy Pond and Rory Williams. The group later forms a reluctant truce with the Borg, who have been betrayed by the Cybermen and are in danger of falling to them. Data and the others manage to restore the Borg Collective and destroy the Cybermen, but their Borg liaison then attempts to seize control of the Doctor's TARDIS. The time machine's intelligence then briefly transfers itself into Data to escape the Borg's control, and the empowered Data overpowers the Borg and throws him out into the Time Vortex before the TARDIS returns to its usual form.
