(Capcom's primary storyline)
— The Nemesis' only spoken word
Nemesis-T Type (ネメシス-Ｔ型 nemeshishu-tī-gata ) was a series of experimental Bio Organic Weapons. Created by Umbrella Europe's No. 6 Laboratory, the Nemesis-T Types were the culmination of the Nemesis Project with the successful implantation of NE-α parasites within T-103 hosts, presenting Umbrella with a highly intelligent and powerful creature. Several Nemesis-T Types were produced, though only one is known to have experienced combat. The resulting creature was called Nemesis for short, and the one sent in Raccoon City was nicknamed the "Pursuer (追跡者 tuisekisha )". In the remake, it was simply referred to as Nemesis.
Umbrella Pharmaceuticals ultimate goal was the creation of Bio Organic Weaponry to sell to the US Army and, through accumulated revenue, fund its own eugenics program. A major flaw found during the t-Virus Project was that sub-par intelligence was an almost unavoidable side-effect and, as a result, R&D projects typically ruled against the practicality of uncontrollable B.O.W.s on the battlefield.[excerpt 1] Though the Hunter Project was promising, the clone species' intelligence still limited them to knowing ten commands. To become truly military-grade, Umbrella needed to develop B.O.W.s with near or like human intelligence.
By 1988 Umbrella USA and Umbrella Europe were competing to do just this. Umbrella USA's Arklay Laboratory set up the Tyrant Project, which aimed to create human mutants without loss of intelligence. Umbrella Europe's No.6 Laboratory, meanwhile, began the Nemesis Project, which aimed to create parasitic organisms that would take over brain functions in a B.O.W. host. Both projects reached impasses which would not be resolved for years to come, with the Tyrant Project lacking results for ten years until the completion of T-002, and the Nemesis Project finding no hosts which could survive the procedure.
By the Summer of 1998, Umbrella USA had successfully created not only the T-002, but a series of genetically altered clones dubbed the "T-103"s. The destruction of the Arklay Laboratory following a biological disaster presented Umbrella with fresh concerns as to the reliability of its products after it emerged a small police team had not only succeeded in killing the failed and outdated prototypes but the T-002 itself. Restarting the Nemesis Project, Umbrella Europe requisitioned several of the new T-103 clones to serve as test subjects. The NE-α parasites planted within their bodies succeeded in hijacking brain functions without killing the hosts. Soon after this procedure, however, at least two of the Nemesis-T Types demonstrated completely unexpected senses of ego and self-awareness, and made an attempt to escape from their laboratory.[excerpt 2]
When Umbrella got word of a t-Virus outbreak in Raccoon City, Umbrella Europe began shipping its B.O.W.s over to the city to take advantage of the crisis. Per HQ's plan, the U.B.C.S. were to engage these B.O.W.s, and Monitors in the city were instructed to record the B.O.W.s' combat skills to verify their reliability as military products. One of the Nemesis-T Types, hereafter "The Pursuer", was deployed via helicopter,[excerpt 3] and given the instructions to hunt down and kill S.T.A.R.S. members, of whom it was shown photographs of so they could be recognised.[excerpt 4] Umbrella was incensed at S.T.A.R.S.' destruction of the T-002 and their attempts to out their bio-weapons research, and so chose its survivors as the Pursuer's targets. In tracking and killing them, it would prove its ability to recognise targets. It was also provided with a rocket launcher, which would test its ability to use weapons. Its mission to kill the remaining STARS members varies upon different accounts, but it would eventually be killed in the attempt, with its remains being vaporised when Raccoon City was destroyed by a missile strike.
On one account, the first S.T.A.R.S. member the Pursuer spotted was Alpha Team's pilot, Brad Vickers, on or before the night of 28 September. Vickers was chased across Uptown Raccoon City and attacked and seriously wounded at the Raccoon Police Station. Alpha Team member Jill Valentine was with Vickers at the time, and the Pursuer began stalking her across the city. It did not, however, attack at all opportunities; while Valentine talked with UBCS survivors inside a tram, the Pursuer watched from a distance to assess the situation and identified the three survivors as secondary targets.[excerpt 5] Aware of the Pursuer and having orders to study it, UBCS Monitor Sgt. Nikolai Zinoviev faked his death in the hopes he would not be recognised as a target. This plan failed, though the Pursuer did not kill him. As the group escaped on the tram, the Pursuer made its move and boarded it, where it was shot at repeatedly by Cpt. Mikhail Viktor. Viktor detonated a grenade in an attempt to kill the B.O.W. in a suicide bombing, but was unsuccessful. Within the Tyrant, the NE-α parasite began secreting chemicals to enhance its body, and it became stronger as a result.
To deny Valentine and Cpl. Carlos Oliveira a chance to escape via a UBCS helicopter, the Pursuer fired a rocket at it, resulting in the destruction of the helicopter and much of the St. Michael Clock Tower. In a fight with Valentine, the Pursuer succeeded in infecting her with a t-Virus strain. It was, however, unable to kill her due to the intervention of Cpl. Oliveira, who destroyed its rocket launcher. The Pursuer staggered through the clock tower ruins, but finally collapsed unconscious in the flames.
Though it made no apparent effort to kill Valentine while she lay unconscious for two days at the clock tower, it turned its attention to Cpl. Oliveira while he searched for a vaccine. On the early hours of 1 October, it made its way to Raccoon City's industrial zone to the north and cornered a recovered Valentine at a bridge over the Circular River. Rather than fight the creature, Valentine jumped into the water below. The two met again within Umbrella's Incineration Disposal Plant P-12A, a facility used to process biowaste. There, the Pursuer was sealed within a chamber for dumping biowaste into a treatment tank. The T-103 body was virtually destroyed by the treatment chemicals, though the parasite survived and escaped. It fed on the remains of another T-103, causing it and the remnants of its host body to merge and mutate into a hideous blob of flesh with tentacles and a jagged beak. Valentine was able to activate Paracelsus' Sword, an experimental US Army rail cannon, which caused further trauma to the B.O.W., and it was finally killed by a series of Magnum rounds.
Nemesis was deployed to Valentine's apartment building while she was on house arrest following an attempt to investigate Umbrella's B.O.W. projects. After smashing through the wall of Valentine's room and shrugging off headshots from her Samurai Edge, it chased her throughout the building as parts of it began catching fire. Valentine briefly evaded Nemesis several times as she made her way to a fire escape; however, Nemesis intercepted her and threw her back into the apartment. After punching a hole that sent it and Valentine falling to the ground floor, it broke off a large chunk of debris to try and crush its prey; Valentine managed to flee outside, leaving Nemesis to accidentally trap itself in the building when its makeshift bludgeon blocked the doorway.
Nemesis eventually caught up to Valentine at a parking garage, destroying a helicopter trying to evacuate her before advancing on its primary target. Valentine attempted to defend herself by hijacking a car and ramming Nemesis with it; unfazed by the impact, Nemesis punched through the windshield and attempted to strangle her. This sent the car flying off the garage and into the ground in front of the RPD, but Nemesis was barely inconvenienced by the fall and the subsequent explosion of the car. With Valentine badly injured, it closed in for the kill, only to be distracted by Carlos Oliveira firing a rocket at it. Nemesis caught the first shot and threw it into a car, but Oliveira's second shot was a direct hit, briefly incapacitating the B.O.W. while he got Valentine to safety.
Nemesis eventually recovered and resumed its hunt for Valentine, finding her leaving the power plant after reactivating power to Raccoon City's subway system. It chased her through the streets, implanting parasites in some of the zombies to make them more dangerous, before following her back to the subway station. Realising that Nemesis was focused on her alone, Valentine drew it away from the station and into the sewers, catching it in an explosion before escaping through a vent.
Nemesis ambushed Valentine on her way out of the sewers, having armed itself with a flamethrower in the interim. It chased its quarry through a building slated for demolition, setting much of the structure ablaze as it cornered Valentine on the roof. In an attempt to kill her adversary, Valentine shot the fuel tank of the Nemesis' flamethrower, rendering the weapon inoperable while setting it and its wielder ablaze; however, the monster quickly resumed its assault, using its flamethrower as a bludgeon. After taking further damage from Valentine, Nemesis collapsed on the burning roof as its prey fled once more.
Valentine didn't get far before Nemesis attacked once again, replacing its ruined flamethrower with a laser-guided rocket launcher. Valentine eventually met up with Oliveira, who helped her distance themselves from Nemesis by blowing it up with a claymore mine; once they were clear, he shot a fuel tank to catch the B.O.W. in a massive explosion. While the blast seemed to have destroyed its rocket launcher, Nemesis survived and managed to board the train that Valentine and the UBCS squad were using to evacuate the survivors of Raccoon City. After the train left the station, Nemesis killed all the civilians before attacking Valentine and UBCS officer Mikhail Viktor in the next car. It shrugged off Viktor's gunfire before impaling him with a tentacle and dragging him into its grasp; this gave Viktor the chance to blow himself up with a block of C4, derailing the train in an attempt to kill Nemesis and save Valentine.
Seriously damaged by Viktor's sacrifice, Nemesis stumbled out of the subway station and fell into a river, briefly leading Valentine to believe that it had finally perished. Her hopes were swiftly quashed when her adversary returned yet again, having mutated into a gigantic amphibious monster resembling a Hunter. Barely keeping ahead of the rampaging creature, Valentine was forced to fight the Nemesis in the Clock Tower courtyard, successfully incapacitating it with three direct hits from a grenade launcher. Nemesis woke up in time to grab Valentine as she attempted to enter the Clock Tower, which led to it having its left arm severed by a large metal gate she dropped on it. In response, Nemesis mutated a massive tentacle to replace its lost limb, using it to stab and infect Valentine before it finally collapsed.
When Oliveira returned to the Clock Tower courtyard half a day after Valentine's battle with Nemesis, the monster had vanished, likely retreating to recover from its injuries. Several days later, the fully-recovered Nemesis found Valentine again in the underground labs of NEST-2; it killed Tyrell Patrick with its tentacle before pursuing Valentine, who managed to escape behind a reinforced security door. Nemesis would stalk Valentine as she tried to synthesise a vaccine for the t-Virus, ambushing her by reaching its tentacle through a vent just as she completed the vaccine. Valentine broke free by stabbing the tentacle with her knife, but Nemesis emerged to grab her again as she tried to take an elevator out of the lab. This time, it was thwarted by Valentine shooting fuel tanks behind it, engulfing the entire room in flames as she made yet another escape.
Nemesis survived the blaze and attacked yet again on the catwalks outside the lab's Disposal Center. Its attempt to tackle her only led to it falling into the main disposal area, but Zinoviev's treachery forced Valentine to follow it shortly afterwards. In the ensuing fight, Oliveira assisted her by keeping an eye on Nemesis as it ran around within the enclosed space of the disposal area while Valentine dealt with zombies dropped through the disposal chutes. The arena worked against Nemesis, as Valentine could electrocute it when it clung to the acid tanks and Oliviera operated a large crane to smash it while it was stunned. After Nemesis was weakened by the damage Valentine inflicted, Oliveira used the crane to knock it out and lift Valentine out of the area before he flooded it with acid.
While the acid bath proved insufficient to stop Nemesis, the trauma forced it to mutate once again. Having grown into a blob-like, building-sized monstrosity with gigantic tentacles and arms, it burst through the wall of an empty hangar (interrupting a confrontation between Valentine and Zinoviev) to make one last attempt to kill its primary target. In response, Valentine attacked her assailant with the FINGeR, an experimental railgun developed by Umbrella's scientists to terminate rogue experiments. After being shot several times, Nemesis finally met its demise when Valentine shoved the railgun down its throat and fired; the resulting blast vaporised Nemesis and blasted a giant hole through the entire facility.

- Excerpt from Complete Conquest of Nemesis, p.81: "”洋館事件” で得られた貴重な実戦データの検証により、 アンブレラの生物兵器研究チームは、 T-ウィルスを用いて造られたB.O.W.のほとんどが、 そのままでは”商品”たり得ないほどに低い知性しか持ち合わせていないという事実を認識するに至った。 究極の完成体と考えられていたタイラントでさえ、 命令を満足に実行することはできなかった――この結果に対し、 各支部の研究チームはそれぞれに異なるアプローチで知性向上の可能性を模索することになる。 その回答のひとつとして提示されたのが、 本社直属のヨーロッパ支部で以前から研究がつづけられていた、 まったく別種の新生物を寄生させることでB.O.W.の能力を強化しつつ、 その頭脳をも完全に支配下においてコントロールしようという独創的な、 そしてより悪魔的な生体改造法であった。 そうして開発されたのが、 寄生生物「NE-α型」――通称ネメシスである。 これらは細胞レベルで生物兵器の脊髄に移植されると、 その体内のT-ウィルス細胞を取りこんで増殖し、 延髄付近に独自の脳を形成する。 同時に中枢神経を侵食して宿主の前頭葉を破壊し、 残る脳機能をすべて自己の脳と連動するよう神経回路を改変してしまう。 このようにしてネメシスは宿主に成りかわって思考をつかさどり、 肉体を我がものとして完全に制御するのである。 なお、 これらを最新型のタイラントに移植した実験体「ネメシスーT型」に関しては、 興味深い報告がなされている。 ネメシスの培養過程で自我が芽生え、 仲間とともに施設から脱走をくわだてたという事例である。 それは実験体の知性が飛躍的に向上したことを示すとともに、 B.O.W.が人類に反旗をひるがえす新たな知的生命体となり得る危険性をも示唆している。そのとき、 人類は生き残れるのだろうか――？".
- Excerpt from Famitsu interview with Yasuhisa Kawamura: Q2. The Pursuer, through what method was it inserted into Raccoon City? A2. The Tyrant was airlifted by a dedicated carrier such as a helicopter. Also, the Hunters were brought in in large numbers by land.
- Excerpt from Famitsu interview with Yasuhisa Kawamura: Q4. How does the Pursuer seem to find S.T.A.R.S. members? A4. The Pursuer's development team were also in charge of educating it; an officer would bait the Pursuer with footage of the S.T.A.R.S. members. Since the Pursuer is intelligent, it understood and carried out its orders.
- Excerpt from Famitsu interview with Yasuhisa Kawamura: Q18. Why did the Pursuer kill Nikolai? A18. The Pursuer saw Nikolai and Jill interact, watching them talking several times and recognised Nikolai as an associate of Jill's. "That woman is dangerous......" - his concern became a reality and he lost his life.
