Bad Guy Bonus Bio #3: Alkhema
"In the early years of GEHIRN, the organization that would eventually become NERV, its lead scientist, Dr. Naoko Akagi, primarily was in charge of developing her greatest creation: the three-in-one supercomputer known as the MAGI, whose three main components were based on a specific aspect of her overall personality-herself as a scientist, herself as a mother, and herself as a woman. The MAGI, however, was not the only major project Naoko worked on. In her spare time, she secretly developed a project meant to be an external 'guardian' of the MAGI, based on her minor interest in advanced robotics, especially the work of two American scientists: Phineas T. Horton, who created the android hero of World War II known as the Human Torch; and Henry Pym, who dabbled briefly in robotics in addition to his work in biochemistry and entomology. Naoko dubbed her efforts 'Project: Jocasta', and, having grown a bit paranoid over the years, secretly embedded a contingency sub-program within the MAGI, with the directive to complete the project even in the event of her death. Even after Naoko's demise did come to pass (thanks to some gaslighting by her so-called 'lover', GEHIRN and later NERV supreme commander Gendo Ikari), the sub-program remained dormant, the project on-hold.
Later on, following the defeat of the otherworldly menaces NERV had codenamed 'Angels', NERV's secret backers, the hidden cabal known as SEELE, launched an attack on NERV's headquarters in the Geofront located in Tokyo-3, Japan. Naoko's daughter and NERV's current chief scientist, Ritsuko Akagi (who at a point during the Angel battles had become the superhero Spider-Woman), managed to beat back SEELE's cyberattack with her own counter-virus and a specially-designed firewall, but in the process unknowingly triggered the contingency sub-program her mother created. The sub-program secretly moved the copied personality engrams Naoko made of herself and, in a hidden area of NERV HQ's most top-secret level, Terminal Dogma, implanted them into the very object of Project: Jocasta's goal. Following the 'Final Battle of Tokyo-3', in which both SEELE's and Gendo Ikari's respective endgames were thwarted thanks mainly to Ritsuko and the other superwomen of Tokyo-3, Project: Jocasta continued to be carried out in secret while NERV HQ and its other branches across the world were in the process of being de-commissioned.
On the final day of the decommissioning efforts, Project: Jocasta was completed, and the result of it awoke and burst onto the scene, terrorizing all who were present in the Geofront. Said result was Alkhema, a powerful, cold, and genocidal gynoid whose personality matrix amplified the worst traits of Naoko Akagi, with its original purpose of protecting the MAGI having since been replaced by the goal of eliminating all human life and making machines dominant over the planet Earth. Ritsuko, as Spider-Woman, and her other superpowered friends and colleagues were barely able to beat Alkhema in their first encounter, though they were sure that, in spite of the destroyed chassis they stood over, their new foe would be back.
By the time Alkhema next encountered the superwomen, who had banded together as a team called the Avengers, she had used her expertise in cybernetics and robotics to create and amass an army of mechanical followers, dubbing her group the Opus Futurae, with she herself as its 'Mother Prophet'. She also unveiled her primary vassal, a sleek, red-faced, green-and-yellow gynoid she named as her 'Vision', whose personality matrix, like Alkhema's, was copied from a human's-said human, in this case, being none other than Ritsuko/Spider-Woman, giving Alkhema (herself a twisted take on Naoko Akagi) a 'daughter' of her own. Alkhema and the Vision, along with the Opus Futurae's forces, proved to be a difficult battle for the Avengers, until something unexpected occurred when the Vision, on studying her opponents while in the middle of the fight, took notice of the camaraderie, trust, and friendship that bolstered their team dynamic and enabled them to be effective against their robotic foes. Concluding that they in truth are good people while Alkhema was in the wrong, the Vision turned on her creator and aided the Avengers against her, destroying her second body in the process.
Some time later, after rebuilding herself, Alkhema would come upon the gamma-powered clone of Ritsuko, Abominatrix, created by the supervillain genius the Leader; the woman had been in hiding following her creator's capture by the Avengers and S.H.I.E.L.D. Alkhema was able to sway Abominatrix to her side by claiming to be Naoko 'reincarnated' as an android, appealing to the part of Abominatrix's mind that wished to have had a better relationship with her mother before her untimely demise. Alkhema utilized Abominatrix well, though behaved just as coldly towards her erstwhile 'daughter' as she did towards the real Ritsuko, with her particularly abusive actions resulting in two significant scars on Abominatrix's face.
Eventually, things would come to a head when Alkhema and Abominatrix next clashed with the Avengers. Up till then, throughout every battle involving Abominatrix especially, Ritsuko/Spider-Woman would try and reason with her erstwhile 'sister', trying to get her out from under the thumb of whoever she took orders from. Though she didn't know it, her in-battle arguments had planted a few seeds of doubt in Abominatrix's mind, much in the same way Ritsuko herself developed them while working under Gendo Ikari. When Abominatrix became caught in-between the warring voices of Ritsuko and Alkhema (with the former actually winning and the latter being especially more cruel), it became too much for her to bear, causing her to turn on her master and tear Alkhema apart in a great rage. (Alkhema, no doubt, was prepared for such an outcome, already downloading herself into her latest body.)
Alkhema would continue to clash with the Avengers over the years, at one point venturing into outer space, where she made contact with the cybernetic alien race known as the Phalanx, an offshoot of another race of techno-organic aliens called the Technarchy. She at one point, back on Earth, would locate, revive, and even 'marry' another creation of Phineas Horton's, the equally-cold machine-supremacist synthezoid known as Adam II, whose goals perfectly aligned with her own."
