Seven of Nine Seven of Nine ( full Borg designation : Seven of Nine , Tertiary Adjunct of Unimatrix 01 ) was a Human female who was a former Borg drone . She was born Annika Hansen on stardate 25479 ( 2349 ) , the daughter of eccentric exobiologists Magnus and Erin Hansen . She was assimilated by the Borg in 2356 at age six , along with her parents , but was liberated by the crew of the in 2374 . She joined the crew and returned to the Alpha Quadrant with the starship in 2378 . Early life . Annika was born on the Federation Tendara colony on Stardate 25479 . Her favorite color growing up was red . ( ) As a young child , Annika often stayed with her aunt , Irene Hansen . Her favorite treats were strawberry tart s , which Irene once used to coax Annika out of a guest room in which she had locked herself . She was very strong - willed and did not hesitate to point out if the strawberries used in baking the tarts were not perfectly ripe . ( ) She wanted to become a ballerina in her childhood . ( ) Time on the " Raven " . Annika ' s parents , Magnus and Erin Hansen , were exobiologists investigating the existence of the Borg . After a great deal of persuasion , the Federation granted the Hansens the use of the , a small long - range craft , to aid them in their investigation . In 2353 , they took Annika , then aged four , along with them . They spent a good deal of time aboard the " Raven " in search of the Borg ; Annika celebrated three birthdays aboard the ship . Eventually , the Hansens encountered a Borg cube and followed it through its transwarp conduit into the Delta Quadrant , the Borg ' s region of origin . They gathered a great deal of scientific data on the biology of Borg drones and the nature of the Collective by moving undetected through Borg space due to multi - adaptive shielding , invented by Magnus Hansen . They even went aboard Borg vessels , using bio - dampener s to remain undetected . However , their research came to an abrupt end in 2356 when an ion storm struck the " Raven " . The ship sustained damage , including , most importantly , damage to the multi - adaptive shielding , which went off - line for 13 . 2 seconds . This left them exposed long enough for the Borg to detect them and perceive them as a target for assimilation . The Hansens tried to evade pursuit by masking the " Raven " s warp trail , but the Borg still managed to pursue and find them . They and their daughter were promptly captured and assimilated . Naturally , the experience was severely traumatic to Annika . ( ) Life as a Borg drone . Annika was placed in a maturation chamber , where the hive mind began to restructure her synaptic pathway s and purge her individuality . She emerged as a Borg drone five years later in 2361 , the turmoil of having been forcibly assimilated replaced with order , and spent the next thirteen years in the Collective with the designation Seven of Nine . As a drone , she assisted in the assimilation of millions , from individuals to entire species . She personally assimilated many individuals from a variety of species , including Humans , Klingon s , Ferengi , Bajoran s , Bolian s , Krenim , and Cardassian s . ( ) In early 2368 , Seven of Nine , along with three other drones in her unimatrix , crash land ed on a planet in the Delta Quadrant . The other drones , who were assimilated as adults , began to regain their identities upon being severed from the Borg Collective , but Seven was frightened as she knew nothing else but life as a drone . She forcibly linked the other drones together into a temporary collective in order to suppress their identities , and they were retrieved soon after . ( ) Seven of Nine remained a Borg drone until 2374 , when she was liberated . ( ) USS " Voyager " . Torn from the Collective . During the brief war between the Borg and Species 8472 in late 2373 , the USS " Voyager " was caught between the two belligerents . Seeking to protect her crew , and being made aware of the extreme threat to the galaxy posed by Species 8472 , Captain Kathryn Janeway forged an alliance with the Borg , offering them the technology behind modified Borg nanoprobe s which could be used as biological photon torpedo warheads against their common enemy , in exchange for safe passage through Borg space and non - assimilation . The Collective assigned Seven of Nine to work with " Voyager " to develop the weapon . When her cube sacrificed itself to save " Voyager " from an attacking 8472 bio - ship , she and a small number of drones beamed onto " Voyager " to continue the work . Janeway was severely injured , leaving her first officer , Commander Chakotay , in command . Seven of Nine wanted " Voyager " to go to another cube , but Chakotay refused . The drones attempted to commandeer " Voyager " s navigation systems to take it to the nearest cube , but Chakotay decompressed the deck the drones were on , blowing them into space . Seven of Nine , however , managed to remain aboard . Instructed to do so by the Collective , she took " Voyager " into Species 8472 ' s realm , forcing deployment of the modified nanoprobe torpedoes to protect the ship . A recovered Janeway resumed command and reinstated the alliance . The torpedoes proved effective . Now vulnerable , 8472 retreated . However , the Collective broke the alliance and Seven of Nine attempted to take " Voyager " to be assimilated . But this was anticipated and a contingency plan was successfully enacted which permanently severed her link to the Collective . Janeway decided to keep Seven of Nine aboard . ( ) The transition back to Humanity was difficult for Seven of Nine . She appeared to accept her severance from the Collective , but tried to contact it at the first opportunity . She was stopped , however . ( ) The Doctor , " Voyager " s holographic chief medical officer , was able to remove most of her implants and restore most of her Human appearance , but her long - term assimilation meant that some parts were vital to her survival and could not be removed . She also refused to be called by her name of Annika Hansen as Seven of Nine was the designation she had always known . But she accepted a shortened version , " Seven " at the suggestion of Captain Janeway . ( ) Shortly after Seven was freed from the collective , " Voyager " neared a moon in B ' omar space , the location of the crashed wreck of the " Raven " , which had been partially assimilated by the Borg when they caught it . A Borg homing beacon aboard was still active . Seven began experiencing visions of a raven and flashbacks to the time she was assimilated . The beacon reactivated several of Seven ' s nanoprobes , giving her an irresistible drive to find the source of the beacon . She escaped " Voyager " in a shuttlecraft and flew to the moon , discovered the ship and recovered the entire memory of her assimilation . ( ) Scientific accomplishments . During her first few months on " Voyager " , Seven attempted to help the engineering crew modify the warp drive to generate transwarp conduit s . The efforts failed , and almost cost " Voyager " its warp core in the process . ( ) Along with Ensign Harry Kim , Seven of Nine designed and constructed the ship ' s astrometrics lab , which used Borg technology to plot routes that trimmed several years off of " Voyager " s journey . The lab became an important asset to " Voyager " and was Seven ' s domain for the rest of the journey . ( ) Using the astrometrics lab , Seven discovered the Hirogen communications network , which allowed " Voyager " to temporarily receive messages from the Alpha Quadrant . ( ) When monthly data streams and , later , real - time communication became possible , Seven helped implement enhancements to " Voyager " s deflector dish . ( ) Seven developed a technique for using Borg nanoprobes to revive an individual who had been dead several hours . It was used on Neelix in 2374 . ( ) A team led by Seven adapted a Borg design to contain and destroy Omega molecule s found in the Delta Quadrant in 2374 . The molecules temporarily stabilized while in the chamber . Seven was the only one to see it happen ; as the Borg considered the Omega Molecule to be " perfection " in its purest form ( but had never been able to stabilize it ) , the former drone underwent what could be described as a religious experience when she saw Omega spontaneously stabilize . ( ) Seven was part of the team which designed the " Delta Flyer " shuttlecraft in 2375 . ( ) Seven assisted in the construction of the quantum slipstream drive installed aboard " Voyager " in 2375 . " In an alternate timeline , the use of the drive destroyed the ship , killing her and everyone else aboard . However , just after the drive was activated , a signal from that timeline was received by Seven via her cortical implant s . This signal contained phase corrections that , when used , collapsed the slipstream , eliminating that timeline and saving the ship and crew . " ( ) When " Voyager " crossed the territory of the anti - telepathic Devore in 2375 , Seven helped develop a transporter suspension technique in order to hide telepath ic crewmembers and Brenari refugees . ( ) In 2376 , Seven developed enhancements to her alcove that allowed her to process information and make connections between various events while she regenerated . This allowed Seven to deduce that photonic flea s had been degrading sensor efficiency and that a catapult built by an alien named Tash employed a tetryon reactor like that of the Caretaker ' s array . However , the process overloaded her cortical implants , and she began drawing wild conclusions concerning " Voyager " s mission and crew . She convinced Chakotay that " Voyager " s presence in the Delta Quadrant was intentional and a prelude to a joint Federation / Cardassian invasion , while later telling Captain Janeway that Chakotay was organizing a Maquis rebellion , using technology of the Caretaker , to launch strikes on Federation and Cardassian targets . She then began to believe that " Voyager " was sent to the Delta Quadrant to retrieve her from the Borg Collective , and that she would be analyzed and dissected upon return to the Alpha Quadrant . She left the ship in the " Delta Flyer " , but Janeway was able to convince her that this ' conspiracy ' was only a delusion caused by her alcove enhancements . She returned to " Voyager " and the enhancements were removed . ( ) A hologram of Reginald Barclay was transmitted to " Voyager " in early 2377 . The hologram supposedly brought information to " Voyager " about using a geodesic fold to return the ship to the Alpha Quadrant . In reality , the hologram had been intercepted and reprogrammed by Ferengi , who wanted to harvest Seven of Nine ' s nanoprobes and sell them for profit . Although the holo - Barclay claimed modifications to the shields would protect " Voyager " while in the fold , Seven eventually discovered that the hologram was deceiving them . ( ) Moral conflicts . " Voyager " rescued a member of Species 8472 from a Hirogen hunting party in mid 2374 . Captain Janeway wanted to return the creature to its native fluidic space because it had told Tuvok of its plight telepathically ; it meant no harm and just wanted to go home . The Hirogen , however , wanted to hunt and kill it . They threatened to destroy " Voyager " unless the 8472 was returned to them . Seven felt that it should be surrendered in order to protect " Voyager " , but Captain Janeway strongly disagreed , saying that it was wrong to sacrifice another lifeform to save themselves . Seven refused to help open a quantum singularity into fluidic space to allow the 8472 to return to its realm , and Janeway confined her to the cargo bay . The Doctor needed nanoprobes to help treat the injured alien , and Seven was ordered to bring them to The Doctor so he could treat it . At the same time , a Hirogen hunter who had been injured from his initial hunt of the 8472 , and who The Doctor had been treating , attacked the 8472 . Seven transported both the Hirogen and the Species 8472 to a Hirogen vessel , which then retreated . Janeway was not happy with Seven ' s conduct , and revoked most of her privileges until she proved trustworthy once again . Seven believed she was being punished for asserting her individuality and her personal beliefs , which the " Voyager " crew had fostered since she had been freed from the Collective . ( ) " Voyager " encountered Entharan weapons broker Kovin in 2374 . Seven worked with him and viewed the weapons he offered to sell , but was very much uncomfortable around him . She later struck him in engineering . With The Doctor ' s help , Seven recovered memories which suggested Kovin had assaulted her and stolen nanoprobes for use as weapons . Circumstantial evidence also supported her story , and " Voyager " tried to apprehend Kovin . It is later determined that her memories were simply ones from her time as a Borg drone mixed with experiences of Kovin . Unfortunately , Kovin was killed when " Voyager " tried to contact him and tell him of his innocence . Both Seven and The Doctor experienced deep remorse over contributing to Kovin ' s death . ( ) When the Omega particles were found in the Delta Quadrant , Seven held a certain fascination with them , since the Borg had tried , unsuccessfully , to stabilize the molecules . She believed they held the key to perfection and that she would be able to use the Borg research to stabilize the molecules . However , Captain Janeway believed it was too risky and the molecules were destroyed . They spontaneously stabilized shortly before being destroyed by " Voyager " . Seven witnessed this and experienced one of her first spiritual moments in the process . ( ) A race of bounty hunters known as the Hazari began attacking " Voyager " in 2375 . A group of aliens called the Think Tank offered to help " Voyager " defeat the Hazari , but wanted Seven of Nine as payment . Kurros , a member of the Think Tank , tried to appeal to Seven ' s quest for perfection and have her join willingly , but she declined his offer . Further investigation revealed that Kurros had hired the Hazari to attack " Voyager " for the express purpose of taking Seven of Nine . The crew developed a plan with the Hazari which involved Seven willingly joining the Think Tank . Once with them , she would disable systems aboard their vessel . Kurros sensed deception , and forced Seven to link with the Think Tank ' s telepathic net . She overloaded the network as the link was established , disrupting the function of their entire ship . Seven was returned to " Voyager " as the Think Tank was overwhelmed with a Hazari attack squadron . ( ) In 2376 , " Voyager " docked at a Markonian outpost . While there , Seven of Nine encountered the group of drones which she had linked together eight years prior . They had since been liberated from the Collective , but were permanently linked due to Seven ' s modifications . They attacked Seven in order to find out what she had done to them , but were stopped by " Voyager " security . Seven later voluntarily linked with the drones to retrieve the memories of the crash , but further damage was caused when the link was broken . Even though the drones were no longer connected to one another , all but Seven were left comatose . They needed their neural implants removed , but it would only give them a month to live . They could be saved if reassimilated into the Borg Collective , but Seven decided that a brief life as an individual was much more valuable than eternal life as a drone , and she ordered The Doctor to remove the implants . The former drones were still upset about the decision made by Seven eight years prior , but understood her reasons and were grateful for their new - found freedom , however short . ( ) Also that year , Seven was part of an away team which discovered the Vaadwaur race , placed in stasis centuries prior . Seven was excited at the prospect of helping to rebuild a society in order to atone for the destruction she participated in while a member of the Collective , and worked with the Vaadwaur to find them a new home . It was later determined that the Vaadwaur were warlike and hostile , and their awakening placed the region of space near their homeworld in great danger . Seven was upset that her intention to help may have caused further suffering . ( ) Again during the same year , Seven and an injured Tuvok were captured by Penk , a Norcadian who organized the spectator sport Tsunkatse , and Seven was forced to fight in the ring . After rescue , Tuvok thanked her for taking his place in a red match and asked if she had recovered . Seven said that her victory only came from her loss of control , and worried that the three years she had spent regaining her Humanity were lost in the ring . However , Tuvok pointed out that her feelings of guilt , shame and remorse meant that her Humanity had been reaffirmed , not lost . ( ) In 2377 , Seven became friends with a Nygean man named Iko , who had committed murder and had been sentenced to death on his homeworld . Initially , Iko took Seven prisoner when he was beamed aboard " Voyager " and made threats to the crew . He later became remorseful when his body and conscience were " healed " by Seven ' s nanoprobes after he was severely beaten by Yediq , the prison warden , when he threatened his family . Seven tried to help him avoid his death sentence , but his crime could not be forgiven by the victim ' s family and he was put to death . Seven was left troubled at the idea that Iko was executed for one murder while she had never been punished for her own actions in the Borg , but Janeway assured her that her time in the Collective was punishment enough . ( ) Dealings with the Borg . While transporting back to " Voyager " in 2375 , a malfunction caused nanoprobe s from Seven ' s blood stream to merge with The Doctor ' s mobile emitter . The nanoprobes quickly assimilated the advanced 29th century technology , and used genetic material from Mulchaey to create an advanced Borg drone , with the emitter at its core . The drone lacked Borg programming , giving Seven the opportunity to communicate with him . She attempted to teach him to be an individual , and he was even given the name One by Neelix , but he wished to learn more about the Borg . Attempts to prevent the Borg from detecting One failed and his attempts to modify " Voyager " s weapons to fight them proved insufficient . He transported aboard the Borg vessel , destroying it from within . His built - in shielding allowed him to survive the explosion badly injured , but he refused treatment and died in " Voyager " s sickbay to keep the crew safe from constant assimilation threats . Seven mourned him as if she had lost a son . ( ) Later in 2375 , " Voyager " s crew prepared for a daring raid on a damaged Borg sphere in order to steal a transwarp coil and substantially shorten their journey home . Seven was contacted by the Borg Queen , who revealed that she had set a trap for " Voyager " and its crew would be assimilated if she did not return to the Collective . Seven reluctantly agreed , learning that she was deliberately granted her freedom as part of a larger plan to assimilate Humanity . Seven resisted the Queen ' s attempts to convince her to develop a nanoprobe virus and was eventually rescued by " Voyager " s crew . ( ) In 2377 she discovered that she was one of a few Borg with a certain assimilation mutation that allowed them to retain their individuality while regenerating inside of an artificial construct known as Unimatrix Zero . Freed from the Collective , she was once again contacted by the others inside . They were on the verge of being discovered and needed her help . With some assistance from " Voyager " s crew , the drones were given the ability to retain their individuality outside of the construct . This allowed them to launch an open revolt against the Collective , plunging the Collective into civil war . ( ) Identity crises . When the Hirogen overtook " Voyager " in 2374 and used its crew and holodecks to conduct hunts , Seven was assigned the identity of Mademoiselle de Neuf ( literally , " Miss of Nine " ) in the French Resistance holoprogram . The Doctor was able to modify her Borg implants and restore her real identity without the Hirogen knowing . She worked with The Doctor and Ensign Kim to stage a counterstrike against the Hirogen and restore the identities of the rest of the crew . ( ) Seven later modified explosives to emit a photonic burst which disabled holographic activity on part of the ship , a crucial event which allowed Captain Janeway to defeat the leader of the Hirogen and return control of the ship to the Starfleet crew . ( ) Seven was stricken with something akin to a multiple - personality disorder in 2375 when " Voyager " neared a vinculum infected with a synthetic pathogen by Species 6339 . Several personalities , including Starfleet officers , a Klingon warrior , a Vulcan official , a Krenim scientist , a Ferengi trader , a woman trying to find her son aboard the at the Battle of Wolf 359 , and a frightened young child , emerged . These turned out to be personalities of individuals assimilated by Seven , and it was soon made clear the malfunctions in her implants were precisely what Species 6339 wished to inflict on the rest of the Collective . The personalities began to take over Seven , and her own individuality was lost . Tuvok was able to use a Vulcan mind meld to retrieve Seven ' s consciousness and the vinculum was deactivated . ( ) In 2377 , " Voyager " s crew was forced to abandon ship after hitting a subspace mine . They were rescued by rogue elements of the Quarren , and had their identities reassigned in order to supply labor and fill a shortage on the Quarren homeworld . The entire crew , except Chakotay , Kim , and Neelix , who were away on the " Delta Flyer " , had their memories of " Voyager " erased and false memories of terrible conditions on their homeworlds implanted . Seven started to use her real name , Annika Hansen , and was given a job as an efficiency monitor in a power distribution plant , working with several other " Voyager " crew members including Captain Janeway , Tuvok , and B ' Elanna Torres . Her Borg desire for perfection made her perfectly suited for the job , and she was often overzealous in chastising workers . The identity reassignment did not completely work on Tuvok , though , and he began to remember his former life , including Seven of Nine . He mind - melded with her , causing memories of her life on " Voyager " and as a drone to resurface . ( ) As the flashbacks continued , Annika investigated Tuvok ' s records . She believed there was a connection to the disappearance of Torres , who had been rescued by the remaining " Voyager " crew , and Annika later learned that Tuvok had accessed files of most of the " Voyager " crew , including Janeway , Torres , and herself . This led her to realize the inconsistency that many new workers from the same species began work on the same day , which was unusual during a labor shortage . Additionally , they were all brought through the neuropathology division , although none of the workers remembered this . Her suspicions were dismissed and explained as an outbreak of Dysphoria Syndrome . Annika was undaunted , and later visited the neuropathology division complaining of the flashbacks in order to access their computer system . While there , she discovered the Dysphoria Syndrome outbreak was actually a cover - up masterminded by a Quarren doctor called Kadan , to hide the fact that " Voyager " s crew and many others had been abducted . This confirmed the story Chakotay had told to Captain Janeway , and Annika and a Quarren official , Yerid , went to the hospital to prevent Kadan from using the reassignment technique on Chakotay and Tuvok . They succeeded , and the entire " Voyager " crew was transported back to the ship . The Doctor was successful in restoring the identities of the entire crew . ( ) Personal development . Although she began to accept her Humanity , Seven was still not completely eager to return to the Alpha Quadrant , and became apprehensive when opportunities presented themselves . ( ) Her reluctance actually proved lifesaving for the " Voyager " crew in 2375 when the ship was nearly ingested by a bioplasmic organism known as the telepathic pitcher plant . She was one of only three crew members ( the others being Naomi Wildman – who , like Seven , had no emotional links to Earth and the Alpha Quadrant – and The Doctor , who was unaffected due to his inorganic nature ) not affected by its illusion of a wormhole back to the Alpha Quadrant . Despite the crew ' s attempts to place her into stasis , she was able to join forces with The Doctor and an alien named Qatai to free " Voyager " . ( ) Like many Borg drones separated from the Collective , Seven suffered a degree of eremophobia ( a fear of being alone ) , which she was forced to face when piloting " Voyager " through an area of space riddled with subnucleonic radiation while the crew was placed in stasis for the duration . ( ) At first , Seven found holodeck s a pointless endeavor , fulfilling a Human desire to fantasize which she did not share . ( ) She reluctantly took part in Janeway ' s simulation , but believed it to be a waste of time . ( ) Later , however , she visited many of Tom Paris ' programs , including " The Adventures of Captain Proton " in which she played Constance Goodheart to Paris ' Captain Proton . She still saw the program as frivolous , and quickly disabled Satan ' s Robot instead of playing along with the storyline of the program . ( ) In 2376 , she visited the Fair Haven program . By this time , she engaged the holographic characters in conversation and participated in the fantasy . ( ) She and The Doctor attended a screening of " Attack of the Lobster People " in a recreation of the Palace Theater in 2377 . ( ) Also during 2377 , Seven created a holographic simulation of " Voyager " in order to improve her social abilities . In the program , her Borg implants had been permanently removed , and she was given a Starfleet science uniform and crew quarters . She also explored a romantic relationship with Chakotay while running the program . She began to use the program excessively , interfering with her duties . ( ) Relationships . Initially , after her release from the Collective , Seven retained much of her former drone personality . She was harsh towards the rest of the crew and often disobeyed Captain Janeway ' s orders when she felt they were incorrect . However , as time went on she gradually formed a close bond with the others , especially with The Doctor , Tuvok , and Janeway herself . ( ) During her time with the Borg , Seven became used to the billions of voices that made up the Collective . After she was separated from them , she found solitude distressing . It became more apparent when Seven was left with The Doctor to watch over " Voyager " as it went through a radioactive Mutara class nebula . When The Doctor ' s program went off - line , she was alone in command of " Voyager " . Her implants began malfunctioning , and she saw convincing hallucinations of an alien named Trajis Lo - Tarik and the " Voyager " crew , seriously injured by the effects of the nebula . She was able to ignore the illusions and eventually save the " Voyager " crew after the ship ' s systems began to malfunction as a result of the nebula ' s radiation . After this experience , Seven joined a group in the mess hall for the first time . ( ) Family . Seven began to read her parents ' journals from their mission aboard the " Raven " , as these were her only link to her parents . She encountered the drone which was originally her father while held captive by the Borg in 2375 . He most likely was destroyed along with the Borg Queen ' s vessel . ( ) She had an ancestor , Sven " Buttercup " Hansen , who was a 22nd century prize boxer . ( ) Seven was present for some of the conversations the " Voyager " crew had with families after two - way communication was established in 2378 . She was reluctant to contact her aunt , Irene Hansen , but the experiences of the crew convinced her it would be worthwhile . Irene was overjoyed to speak with her , but Seven was slightly uncomfortable when Irene used her real name , Annika . ( ) Seven also had a " son " . A transporter accident involving The Doctor ' s mobile emitter and Seven ' s nanoprobes resulted in the creation of a Borg drone , One . At first she was reluctant to teach the drone about individuality and life on " Voyager " , but she eventually became attached to him , almost maternally . When One decided to allow himself to die for the benefit of the crew , Seven was deeply upset . ( ) Friendships . While under the influence of synthehol , Seven told The Doctor and several other " Voyager " crew that she considered them all " very good friends . " ( ) Kathryn Janeway . Captain Janeway made the decision to sever Seven of Nine from the Collective . She helped her through the difficult transition to Humanity in 2374 , trying to force memories of her life as Annika Hansen to surface . ( ) Janeway also tried to tutor Seven in the arts and further cultivate her Humanity . ( ) Seven was not hesitant to question Captain Janeway ' s decisions , sometimes publicly . She thought Janeway placed the crew in unnecessary danger by exploring the Delta Quadrant and contacting civilizations such as the Mari , rather than setting a course for home . ( ) When " Voyager " believed that Starfleet had sent the to bring the crew home in late 2374 , Seven did not want to return with the crew . She requested to remain in the Delta Quadrant , possibly returning to the Borg Collective . Janeway was dismayed that Seven had not found an appreciation for her new life in the year she spent aboard " Voyager " . Later , the ship was found to be a fake created by Arturis in order to deliver the " Voyager " crew to the Borg . While trapped aboard the ship , Seven confessed to Captain Janeway that she was thankful for her individuality and was not eager to return to the Collective . She also confessed that it was fear of the unknown , that is , what will happen after she returns to Earth , that discouraged her from going back . ( ) In 2375 , Seven inadvertently helped The Doctor recover memories of Ensign Ahni Jetal , erased from his database when they caused problems with his ethical subroutines . Captain Janeway intended to erase the memories once again , but Seven voiced concern . She felt that erasing The Doctor ' s memories would essentially mean turning a blind eye to his development as an individual . Seven admitted that she saw Janeway as a role model , but began to question that image after her treatment of The Doctor . This gave Janeway more to think about , and she decided to restore the memories to The Doctor . ( ) Seven of Nine often had the ear of the captain , coming to her whenever she needed moral guidance , or wanted to express something she had learned about Humanity . One such occasion occurred in 2378 , when Seven dropped a barrier protecting the Ventu from cultural contamination . Before making any command decisions , Janeway asked Seven what she thought of the Ventu ; Seven found them antiquated , but resourceful . She believed that if the Ledosian s were allowed to contaminate them more , " something unique would be lost . " ( ) In an alternate timeline , Seven of Nine was fatally wounded on an away mission and died upon her return to " Voyager " . Her death deeply affected the Janeway of that time . ( ) B ' Elanna Torres . " Voyager " engineer B ' Elanna Torres was distrustful of Seven , and the two almost came to blows several times during Seven ' s early days on " Voyager " . Torres was stunned that Seven experienced no remorse over the fate of civilizations such as the Caatati , devastated by the Borg . ( ) Torres believed Seven was cold , rude , and acted like the crew of " Voyager " were Borg drones . She told Chakotay that she did not want to be held responsible if she and Seven got into a physical altercation . Chakotay , in turn , put Torres ' own attitude in check when he made it clear that she needed to find a way to work with Seven and that she would be held responsible if a fight occurred . Seven earned some of Torres ' respect when she used a feedback pulse to disable a Hirogen who threatened the ship ' s use of the communications network in 2374 ( although she made sure the disapproving Janeway was out of earshot first ) . ( ) Seven studied Torres and future husband Tom Paris during their courtship , even noting the times when the two had sexual relations . Upon discovering this in 2375 , Torres was quite incensed . ( ) While the two women would never become close friends , they did develop a good working relationship as time passed . By 2377 , the two had grown more comfortable with each other . Torres comforted Seven when she was faced with death after her cortical node malfunctioned , telling her that she made valuable contributions to the crew of " Voyager " . ( ) Torres talked to Seven about Paris shortly before their marriage in 2377 . Seven suggested that Torres try to participate in some of Paris ' interests in order to improve their relationship , which led to Torres ' participation in the Antarian Trans - stellar Rally . ( ) To Torres ' shock , Seven presented her with a baby shower present and complimented her on her hair the following year . ( ) Naomi Wildman . Naomi Wildman was the first child born aboard " Voyager " . She was initially scared of Seven and afraid that she could assimilate her . Soon , she became fascinated with Seven , and began following her in early 2375 . Seven was initially annoyed with her , and disapproved of Naomi ' s study of Borg species designations . While Seven was experiencing problems due to contact with the infected vinculum , one of the personalities to emerge was that of a small child . She played kadis - kot with Naomi , to Naomi ' s delight . After the crisis was resolved , Seven decided to instruct Naomi in astrometrics , giving her several star charts and species information to study . Seven also requested a game of kadis - kot with Naomi . ( ) They became friends , going to lunch or playing games of kadis - kot . They had in common that they often couldn ' t understand the crew ' s determination to return to Earth . This fact proved helpful when " Voyager " was confronted by the telepathic pitcher plant , which made the rest of the crew see it as a wormhole to Earth . Seven and Naomi were unaffected due to their indifference about returning home and , aided by Qatai , who had hunted the creature for years , and The Doctor , they were able to trick the creature into expelling " Voyager " . ( ) When Seven was kidnapped by the Borg , Naomi demonstrated her determination to save Seven , and presented to Captain Janeway a plan to rescue Seven . ( ) Seven once stated that she thought of Naomi as her family on board " Voyager " . ( ) Surrogate motherhood . In 2376 , Seven became a temporary mother figure to a group of children whom " Voyager " had discovered aboard a derelict Borg vessel . She cared for the children , named Icheb , Mezoti , Rebi , and Azan , until the latter three were returned to their own people in 2377 . ( ) Seven was frustrated with her initial attempts to tutor the children . She designed a rigid schedule for their activities , enacting serious punishment when they failed to adhere to the schedule . They rebelled against the restrictions , and an exasperated Seven told Chakotay she no longer wished to supervise them . He made her realize that while consistency is important , children also need spontaneity . Her efforts were much more successful once she made allowances for that . ( ) Icheb . After discovering that he had been genetically engineered as a weapon against the Borg , the eldest of the children , Icheb , remained with " Voyager " and he and Seven formed a close relationship . ( ) Icheb expressed a desire to apply for Starfleet Academy admission , and hoped Seven would speak to the captain about having Commander Tuvok teach him preliminary courses . Around this time , Icheb donated his own cortical node when the failure of Seven ' s jeopardized her life . She initially refused to accept his help , placing his safety above her own despite his research showing that he was far more likely to survive the loss of the node than she was . ( ) Romance . Harry Kim became physically attracted to Seven shortly after she joined " Voyager " . Noticing this , she addressed the situation with him , asking him if he desired to " copulate " , thereby embarrassing him . However , she did tell Kim late at night in the mess hall that she was willing to explore her sexuality and told him to take his clothes off . ( ) The attraction was also painfully obvious to the rest of the " Voyager " crew . ( ) She seduced him in a dream caused by aliens encountered in 2374 . ( ) Under The Doctor ' s tutelage , Seven first explored true romance in 2375 . She chose engineering crew member William Chapman after determining that their interests were compatible . However , Seven ' s directness was too overbearing for Chapman , and the date ended up in disaster when Seven accidentally tore a ligament in his shoulder while dancing . ( ) In 2378 , Seven was distressed to discover that the Borg had deliberately programmed the cortical implant of their drones to shut down in the event that the drone began to experience strong emotion , thus killing the drone . The Doctor believed he could reprogram the affected implant , but Seven refused treatment . Later that year , she changed her mind , and she underwent the surgery . ( ) Axum . While Seven was assisting the drones of Unimatrix Zero , she mainly dealt with a man named Axum , with whom she had had a romantic relationship within Unimatrix Zero while she was still a drone . The relationship sparked again , strengthening her resolve to help those within the Unimatrix . However , Axum was physically aboard a scout vessel at the border of fluidic space in a remote sector of the Beta Quadrant , making it impossible to contact him again once Unimatrix Zero was destroyed . ( ) The Doctor . The Doctor was responsible for the removal of Seven ' s implants , and also conducted her weekly maintenance sessions . He also took it upon himself to teach Seven social behavior , using the same interpersonal relationship exercises Kes once practiced with him . ( ) Later , he created a holodeck simulation of " Voyager " for her to become more comfortable with large social gatherings . ( ) The Doctor encouraged Seven to explore romantic relationships in 2375 , coaching her in the basics of dating and grooming . He also discovered her singing voice , and the two sang a duet of " You Are My Sunshine " . He was partially motivated by a wager made with Ensign Paris , who believed that Seven would not be able to bring a date to a reception planned aboard " Voyager " without making a scene . Although Seven ' s date with Lieutenant Chapman ended up in disaster , she attended the reception with The Doctor , and charmed the guests with a toast to individuality . However , she was hurt to discover that The Doctor ' s help was due to the bet . At this point , The Doctor found that he himself was falling in love with Seven , but refused to admit it to her . He tried to apologize to her , but she came to him first and said she no longer needed the lessons in romance because there were no suitable mates aboard . The Doctor was very disappointed that Seven did not reciprocate his feelings . ( ) In 2376 , The Doctor was stranded aboard the along with Seven , and the crew disengaged his morality subroutines to extract activation codes for their warp drive from Seven ' s cranial implants , which would leave her mentally disabled . The Doctor almost went through with the procedure , but Captain Rudolph Ransom stopped him . He apologized to Seven for the incident , and she held no ill will towards him . ( ) The Doctor created a subroutine for daydreaming in early 2376 . Seven featured prominently in several fantasies , either serving as a damsel in distress or competing with other female " Voyager " crew members for The Doctor ' s affections . He even fantasized about painting her in the nude . When the fantasies began to overrun his program , his mental activity was tied into the holodeck , allowing Seven to see what he had been daydreaming . She did not take offense , but after she kissed him following Captain Janeway ' s announcement that the Emergency Command Hologram subroutines would be developed , she made it clear that it was simply a platonic gesture . ( ) While Ensign Kim , Seven , and The Doctor conducted a routine survey on board the " Delta Flyer " in 2377 , they were captured by a race known as the Lokirrim . The Lokirrim had waged war against holographic lifeforms who rebelled against Lokirrim rule , and as a result , banned all holographic activity within their borders . Seven transferred The Doctor ' s program to her cortical implant in order to hide him from the Lokirrim and prevent him from being decompiled . In the process , The Doctor took control of Seven ' s motor abilities , and was essentially trapped in her body . The Doctor tried to engineer an escape by cultivating a relationship with a Lokirrim official , Ranek , but the new sensations of taste and emotion were too tempting for The Doctor . He ended up overindulging in several foods and causing pain to Seven . Ranek later called Seven to the ship ' s bridge with the intention of setting up a romantic liaison . Although The Doctor was able to see his command codes , Ranek attempted to kiss him in Seven ' s body , which was not reciprocated . Shortly afterward , he went to complain about the incident to Jaryn , a crewmember The Doctor had been working with to treat injured Lokirrim crew . The Doctor became sexually aroused when Jaryn gave Seven a neck massage . Both incidents greatly irritated Seven , and once The Doctor had been returned to the mobile emitter they got into an argument about the values of indulgence . The Doctor felt Seven showed excessive restraint and did not allow for superfluous pleasure , which The Doctor believed was an important part of life . Kim managed to return the subject to escape , and The Doctor and Seven worked together once again to transmit a distress signal to " Voyager " . The Doctor was downloaded back into Seven ' s implants , and was able to convince Ranek to join her on a " second date . " They knocked him out at the first available opportunity , and transmitted a message to " Voyager " including the ship ' s command codes . Their plan was discovered by Jaryn , and Seven was taken captive . After " Voyager " arrived , Seven returned The Doctor ' s program to the mobile emitter and they escaped . Upon their return to the ship , Seven decided that The Doctor had a point about her restraint concerning pleasures such as food . She brought a meal to sickbay and described the sensations of eating it to The Doctor , allowing him to experience it vicariously . ( ) When The Doctor ' s rights as an individual came into question , Seven testified at the hearing conducted with Starfleet Command . She spoke highly of The Doctor , appreciative of his efforts to develop her individuality . ( ) In 2378 when The Doctor believed he was about to die , he finally admitted his feelings for her , and was embarrassed when he survived . ( ) The Doctor was also crestfallen when he learned Seven had begun to date Chakotay . ( ) Chakotay . Like many of the crew , Chakotay was distrustful of Seven during her first year on board . He questioned Captain Janeway when she chose to leave Seven in control while the ship traversed a Mutara - class nebula . ( ) Chakotay was interested in the early history of space exploration , and jumped at the chance to retrieve the " Ares IV " command module from a graviton ellipse encountered by " Voyager " in 2376 . Seven saw this fascination as dangerous , and she was proven right when the " Delta Flyer " , sent to retrieve the module , was trapped in the ellipse . She was upset with Chakotay , but her attitude changed when she beamed over to the command module to retrieve a component to repair the damaged " Flyer " . Chakotay told her to savor the moment and recover as much history as possible . She replayed Lieutenant John Kelly ' s logs , and was touched by his devotion to duty . She had his body beamed back to the " Flyer " and spoke in admiration of Kelly at his funeral aboard " Voyager " . ( ) Seven considered a romantic relationship with Chakotay in 2378 . In her holodeck simulation of " Voyager " , Chakotay became her love interest , and she went on several dates with him . To her embarrassment , The Doctor learned of the simulation when she collapsed on the holodeck due to her Borg programming , designed to shut down the implants of a drone should he / she experience strong emotion . These implants would require dangerous , repeated surgeries to remove , and Seven chose not to proceed . ( ) The Doctor strove to develop a safer method of removing this obstacle to her development and several months later he was able to remove the implants with a single surgical procedure . After the affected implants were removed , Seven was free to become involved with the real Chakotay , and the two began dating in 2378 . Neelix gave Seven ideas for dates . In an alternate timeline , when Admiral Janeway was forced to convince Captain Janeway to return to the nebula , she revealed that Seven of Nine and Chakotay later married . ( ) Physiology . The Doctor was able to remove most of Seven ' s implants and restore most of her Human appearance , but she still had some Borg technology left ; these were tied into her vital functions , and removing them would have killed her . She also still needed to regenerate , like any Borg drone , using a Borg alcove , although she had been known to not need regeneration for extended periods of time ( ) . She was given a special suit and also issued a combadge . ( ) As a former drone , Seven had considerable superior physical characteristics over most Humans . Her visual acuity was vastly superior , due to her ocular implant , along with an eidetic memory and superior physical strength for a healthy Human woman her age . ( ) As for her regular Human senses , they were more acute than the average Human as well . ( ) Her heart and respiratory system were completely reinforced . ( ) She was also much more resistant to injury and many forms of radiation , including chroniton and subnucleonic radiation that would quickly kill an ordinary Human . ( ) In addition , she became an extremely proficient martial artist , mastering the Norcadian martial art of Tsunkatse . ( ) With her Borg implants , she was also able to serve as a physical host to any holographic character . ( ) Her enhanced Borg physiology also had its downside , such as being prone to malfunctions or failures or receiving unwanted transmissions from the Borg Queen or other Borg devices . ( ) Her powerful nanoprobe s were highly sought after and in the Ferengi market each sold for six bars of latinum . In fact , in 2377 Ferengi marauders attempted to obtain Seven of Nine ' s nanoprobes by perpetrating an elaborate scheme . Seven ' s nanoprobes had multiple applications which made them so valuable , including slowing the aging process and even reanimating dead tissue . ( ) As the result of an infected Borg vinculum that had identified her as an errant drone and was trying to reintegrate her into the collective , Seven once developed multiple personality disorder exhibiting the behavior and personalities of the individuals assimilated by the Borg during her eighteen years as a drone . ( ) When she was once experimenting with the nature of individuality and intimate relationships , experiencing a host of strong emotions unfamiliar to her , her cortical node shut down as a fail - safe mechanism to deactivate drones who started to regain their emotions . ( ) Alternate Seven of Nine . Holograms . Seven of Nine was holographically duplicated on a number of occasions : Alternate realities and timelines . In 2374 , most of " Voyager " s crew was duplicated by a biomimetic lifeform known as the " Silver Blood . " ( ) The crew eventually agreed to allow the silver blood to replicate every individual on board , and the real crew left the class Y world . They began to forget their origins and ultimately started to believe that they were the real " Voyager " crew and set a course for the Alpha Quadrant . By mid 2375 , they had developed an enhanced warp drive and were closer to the Alpha Quadrant than the real " Voyager " . At the wedding of that ship ' s Tom Paris and B ' Elanna Torres , Seven caught the bouquet . Shortly following this event , the enhanced warp drive began to degrade the structure of the ship and the crew , as it was harmful to the " Silver Blood . " Captain Janeway decided to continue to the Alpha Quadrant in spite of this discovery , and did not attempt to locate a Class Y planet until many of the crew had succumbed to the degradation and the ship was severely damaged . Seven was one of the last crew members to degrade , and she attempted to build a message beacon out of non - affected materials to launch and hopefully be recovered . The beacon was later destroyed after the launch mechanism failed , and the " Voyager " disintegrated just as the real " Voyager " caught up to it . ( ) Sometime in the 29th century , Captain Braxton , of the Federation timeship , went back to 2371 and planted a temporal disruptor on " Voyager " in order to destroy it . The crew of the " Relativity " recruited Seven of Nine from late 2375 to help find the device because her ocular implant was capable of detecting it . Seven was altered in order to look Human , given a blue Starfleet uniform , and sent to several time periods to pursue Braxton . Unfortunately , the side effects of the time travel were detrimental , and Seven died twice before discovering that Braxton was responsible . Further complicating matters , the timeline was contaminated by Seven ' s presence twice in the year 2371 and once in 2375 , shortly before Seven was taken . Eventually , Braxton was apprehended and Captain Janeway helped repair the timeline by stopping Braxton before he ever had the chance to plant the disruptor . Slightly confused , Seven and Janeway were returned and reintegrated to the year 2375 and instructed not to tell of their experiences under order of the Temporal Prime Directive . ( ) When " Voyager " was fractured into several different time periods upon encountering a spatial rift in 2377 , the cargo bay was reverted to 2374 when the Borg first transported onto " Voyager " . Chakotay was the only crew member not affected , and contacted the Seven of Nine of this time period . She designed a plan to use a chroniton field to bring the ship back into temporal sync . She later helped the " Voyager " crew retake engineering from Seska in 2373 . ( ) In an alternate timeline occurring shortly after " Voyager " s first encounter with the Krenim in 2374 , Seven developed a temporal shield ing technology which protected the ship from the Krenim chroniton torpedo es as well as alterations in the timeline caused by Annorax ' s weapon ship . The shield was perfected when she determined the exact phase variance of an intact torpedo lodged in " Voyager " s hull , found while making repairs to " Voyager " s badly - damaged systems . The torpedo detonated while Seven and Tuvok were nearby . Although Seven was unharmed , Tuvok was blinded . She assisted him in daily tasks aboard " Voyager " , as surgery to correct the blindness was impossible in " Voyager " s state . When " Voyager " s crew was forced to share quarters due to power failures , she shared quarters with Ensign Brooks . Seven found living with her difficult , as her personal habits were " chaotic . " Seven remained aboard " Voyager " when most of the crew abandoned ship . ( ) Seven later helped fit temporal shielding to the Mawasi fleet . The timeline was eradicated when " Voyager " collided with the temporal weapon ship , erasing it from history , along with any events caused due to the existence of the weapon ship . Thanks to Seven ' s temporal shielding , " Voyager " was able to erase the weapon ship from existence , thereby saving the entire galaxy from Annorax ' s catastrophic changes . ( ) In another alternate timeline created when " Voyager " used a quantum slipstream drive in 2375 but rode it all the way to the Alpha Quadrant , the ship crash - landed on an arctic planet , killing its entire crew . Harry Kim and Chakotay , who had survived the trip in the " Delta Flyer " , spent fifteen years trying to locate " Voyager " . They developed a plan to use a Borg temporal transmitter that they stole from the Federation to transmit the correct variance to Seven of Nine ' s cranial interplexing beacon in the past and therefore alter history . They stole the " Delta Flyer " and took it to " Voyager " , needing Seven ' s cranial implant and The Doctor ' s expertise to find her translink frequency allowing them to send the course corrections to and prevent the crash . Seven was located on the bridge and the reactivated Doctor removed her cranial implant . Once he was able to find her translink frequency – 108 . 44236000 – he attached it to the beacon . The first attempt to send the correction directly to her cranial implant failed , and " Voyager " was still lost . Kim then sent another correction , designed to collapse the slipstream , just before the " Flyer " , the alternate Harry Kim , Doctor , Chakotay , and his girlfriend Tessa Omond were destroyed by the . The new plan worked , thus negating their deaths , and " Voyager " was saved . ( ) In yet another alternate timeline erased due to the actions of Admiral Kathryn Janeway , Chakotay and Seven were married aboard " Voyager " in the 2380s . However , Seven was killed on an away mission before " Voyager " returned home , and Janeway blamed herself for her death . This was a major motivation for her to travel back to 2378 and alter the past to bring " Voyager " home in that year . ( ) In the 31st century simulation of " Voyager " at the Kyrian Museum of Heritage , the incomplete records from " Voyager " s visit in 2374 painted the crew as murderers and savages . Seven , still with full Borg implants , was the leader of a group of Borg aboard " Voyager " who were sent to assault several Kyrian s . This simulation was corrected after the reactivation of a backup copy of " Voyager " s EMH from the EMH backup module stolen during the ship ' s visit . ( ) Miscellaneous . Seven ' s first real food after being severed from the Borg collective was chadre ' kab . ( ) She also developed a fondness for strawberries , left over from her childhood . ( ) In The Doctor ' s holonovel entitled " Photons Be Free " , Seven ' s alter ego was a former drone named " Three of Eight " . She was the only person aboard the " Vortex " who spoke in defense of The Doctor , and helped him escape after he was arrested for expanding his program . She pleaded with Captain " Jenkins " to prevent The Doctor ' s program from being decompiled , calling it a crime that individuals like The Doctor were not appreciated . When Tom Paris temporarily rewrote the program , the character became " Two of Three " . Paris made light of The Doctor ' s obvious crush on Seven by making the holographic doctor in his program chauvinistic . The EMH character used a Klingon aphrodisiac on " Two of Three , " causing her to react positively to his affections . ( ) Seven and Chakotay made first contact with the Ventu on Ledos before the start of a conference on that planet . Initially hesitant to reach out to the primitive race , Seven was so moved by her experiences with the Ventu that she convinced Janeway to restore the energy barrier protecting the Ventu ' s lands and customs from the Ledosian s . ( ) Appendices . Background information . Seven of Nine was played by actress Jeri Ryan . She first appeared in the fourth season opener , . Young Annika Hansen was played by Erica Lynne Bryan in " Scorpion , Part II " and , and Katelin Petersen in . The concept of Seven of Nine began while Brannon Braga was sitting at home , late one night , and saw a televised promotion for the Borg - centric third season installment . ( " Braving the Unknown : Season Four " , VOY Season 4 DVD ; " Cinefantastique " , Vol . 30 , No . 9 / 10 , p . 75 ) The idea of having a Borg crewman aboard the starship " Voyager " – a notion that instantly appealed to Braga – occurred to him as he was watching the advertisement . ( " Cinefantastique " , Vol . 30 , No . 9 / 10 , p . 75 ) He then brought the character concept to the attention of fellow writer Joe Menosky . Braga later remembered , " " I called Joe Menosky , and pitched this idea , and he thought it was a great idea . And then we talked about it and all the things . . . ' What would that mean , to have a Borg character ? ' It would be really cool . " " ( " Braving the Unknown : Season Four " , VOY Season 4 DVD ) Braga also related , " " I called Joe Menosky and we brainstormed . I wanted to make sure it wasn ' t a stupid idea . " " ( " Cinefantastique " , Vol . 30 , No . 9 / 10 , p . 75 ) After Menosky approved of the concept , Braga called Executive Producer Rick Berman . " " It was late , but I was so excited [ . . . ] He really liked the idea but he had the stroke of genius , ' Make it a Borg babe , " " said Braga . " " And we just talked about it , for a couple hours , and we just thought , ' This is a really cool idea . This could be really . . . just the thing we need . " " ( " Braving the Unknown : Season Four " , VOY Season 4 DVD ) This marathon conversation between Berman and Braga took place in the spring of . ( " " , p . 348 ) Berman was not the only executive producer to whom Braga suggested the idea of a Borg crew member , however . " " I [ . . . ] took it in to Rick Berman and Jeri Taylor , " " Braga said , " " and they liked the idea . " " ( " Cinefantastique " , Vol . 30 , No . 9 / 10 , p . 75 ) Taylor herself commented , " " The idea of having a female Borg was one of those that came largely through spontaneous combustion . It started with Brannon , and quickly gained a great deal of support . " " ( " " , p . 348 ) Seven of Nine was originally called " Perra " and had witnessed friends of hers being brutally killed around her at an outpost on Kelta Prime , a long time before she encountered " Voyager " and its crew . During that early incident , her humanity , according to Perra herself , had " died . " There was a time thereafter when she wished she had died along with her friends but , when she joined the Borg Collective , that emotional pain disappeared and she found the voices of the Collective to be comforting . This backstory was even written into casting sides that , in 1997 , were used to audition the part . The call sheets for the episodes " Scorpion , Part II " and " The Gift " also featured Ryan in the role of " Perra " . Brannon Braga opined that Seven of Nine was the Spock or Data the show needed . " " The Doctor came close " , " he said . " " I liked The Doctor character . But Seven of Nine to me was like – I was inspired by that Truffaut movie about trying to tame someone who was raised by wolves or in this case someone raised by Borg . " " Brannon Braga envisioned , upon devising the Seven of Nine character , that she would ultimately be portrayed as meeting an unfortunate end . " " Seven of Nine was , for me , designed to be a character that was gonna die tragically , " " Braga admitted . " " I planned that . " " He elaborated , " " I thought she should have somehow sacrificed herself to get the closest thing she had to a family home . I think it would have been amazing but I was shot down . I was not running the show at the time ; it was Ken Biller and Rick . " " An actress who auditioned for the role of Seven was Hudson Leick ( Callisto from " Xena : Warrior Princess " ) . ( " Beyond the Final Frontier " , p . 308 ; ) Another actress who read for the part was Claudia Christian ( Ivanova from " Babylon 5 " ) . ( " Beyond the Final Frontier " , p . 308 ) Brannon Braga was involved in the casting process from the start . He commented , " " We read a lot of different kinds of actresses of different ages . We narrowed it down to three , and Jeri Ryan was the best . " " ( " Cinefantastique " , Vol . 30 , No . 9 / 10 , p . 75 ) Ryan tried out for the role in mid - May 1997 . She recalled , " " I , of course , auditioned like everyone else . As a matter of fact , I read a couple of times and then I got the job . " " ( ) Jeri Ryan ' s first day on " Star Trek : Voyager " was Tuesday on which she had a medical appointment like all the other main cast members . On this day , there were also the interviews with Ryan ' s possible stand - in s for which recurring background actress Cameron was cast . Cameron later left the production during the episode and the stand - in position was re - cast with Brita Nowak . On Wednesday , Ryan had her makeup and wardrobe tests followed by fittings on Thursday . Her first day filming " Scorpion , Part II " was on Friday with a makeup call at 6 : 30 am and a set call at 10 : 00 am . On this day , Ryan filmed some bridge and ready room scenes on Paramount Stage 8 . Seven ' s infamous costume began as a silver version in , which was also used in and . It was retired because the material was too restrictive for actress Jeri Ryan ' s movement and it was difficult for her to breathe in , especially when she sat down . A new brown uniform , featuring a lower neckline , debuted in , and a variant with a small collar is visible in . A cobalt blue costume with grey shoulders and arms first appeared in but was replaced by an all - cobalt version in . A plum - colored outfit first appeared in . Seven can be seen wearing a Starfleet uniform on only two occasions , the first being , when she is undercover in " Voyager " s past , and the second being in , in a holographic simulation . Her Borg costume was also revived in several episodes , mostly in scenes . Some fans jokingly call Seven " Barbie of Borg " and 36D of 9 , due to a common belief that she was brought on board " Voyager " mainly to boost ratings among male viewers . Jeri Ryan freely admitted this to be true , saying , " " I knew exactly what I was in for when I had my first costume fitting . Clearly my character was added to the show for sex appeal , which remains the one way to get attention very quickly . I don ' t think it ' s the only way to get viewers to watch strong women , but it worked . " " . ( TV Week magazine ( Canada ) of May 8 - 14 , 1999 pages 6 - 7 , 9 from " Super Moms " , an interview by Michael Logan ) Kate Mulgrew admitted that she and Jeri Ryan did not see eye - to - eye while filming " Voyager " because " " I had thought ' damn , we were going to forgo all of this with a female captain . ' But the demographics proved the audience wanted more sex . " " However , she reflected that Ryan " " did a marvelous job in a very difficult role . It was very clear to anyone with eyes in their head that Jeri Ryan ’ s beauty and sexual appeal were an important part of the numbers . " " The character Seven of Nine appeared in ninety - seven episodes of " Star Trek : Voyager " . Counting the Kyrian recreation of the character in , the biomimetic copy in , and an illusory Seven of Nine in , she appeared in exactly one hundred episodes . Apocrypha . In the PC videogames " " and " " , Seven was responsible for creating a device called " I - Mod " ( Infinity Modulator ) . The I - Mod was specifically made to be used against the Borg . The I - Mod device was made into a weapon of its own ( a rifle ) , capable of firing unique infinitely modulated shots that made adapting impossible . According to the video game " " , Seven of Nine was born on Gemaura III to parents Seka and Han . In an alternate future seen in the " Deep Space Nine " book trilogy " " , Seven , along with " Voyager " and her crew , returned to the Alpha Quadrant at an unspecified time . By 2399 , Seven had been promoted to admiral . Seven , along with Hugh , helped to negotiate a treaty between the Federation and the Borg Collective , in the name of fighting the Bajoran s , with whom the Federation was at war . In this future , she was apparently romantically involved with The Doctor . The entire timeline was reset thanks to Benjamin Sisko and the crew of Deep Space 9 . In the book series , Seven broke up with Chakotay , moved in with her aunt , and attained much undesired celebrity . She eventually joined a Federation " think tank " with The Doctor . In the " Next Generation " relaunch novel " Before Dishonor " , Seven of Nine had become a civilian instructor at Starfleet Academy specializing in cybernetic technology . When Janeway was assimilated to become a new Borg Queen , Seven joined the crew of the to reactivate the planet killer weapon with the assistance of Geordi La Forge and Spock in an effort to attack and destroy the Borg ship attacking Earth . Following the events of " " , Seven of Nine ' s remaining Borg implants were seemingly destroyed . She underwent a severe emotional shift , yet to be explained , and began asserting her true name as Annika Hansen once again . In the timeline for " Star Trek Online " , Seven of Nine joined Starfleet after " Voyager " s return to the Alpha Quadrant , and was assigned to a special Borg Task Force . When the task force was dissolved in 2385 – Starfleet believing the Borg were no longer a threat – Seven angrily disagreed with the decision and resigned from Starfleet , accepting a position at the Daystrom Institute instead . Seven appears in " Delta Rising " , the second expansion to STO , voiced once again by Jeri Ryan . In the wake of " Operation Delta Rising " , a campaign to return to the Delta Quadrant to fight the Undine , Tuvok – now an admiral and commanding " Voyager " – asked Seven to leave the Daystrom Institute to work for the new Delta Alliance . Seven and her research team are rescued from a small outpost after the ship carrying them , the USS " Callisto " , is destroyed . Following a Voth fleet that mysteriously disengaged from combat , Seven and her rescuers arrive at the homeworld of the Turei , where they learn that the Vaadwaur have managed to gain advanced technology and have begun a campaign to reconquer the Delta Quadrant . Seven again expresses her guilt at awakening the Vaadwaur , but accepts Tuvok ' s offer to serve with him again on " Voyager " to combat the new threat . She also works alongside the Cooperative , a group of free Borg drones , in their efforts to avoid being reassimilated by the Collective or destroyed by their opponents .
