Copy technology Copy technology is employed by Dr . Hollander to create an army by endowing other creatures with the cells of Genesis Rhapsodos and Angeal Hewley in " Crisis Core - Final Fantasy VII - " to be used in the Genesis War . Process . A copy is created when the cells of a G - type SOLDIER are implanted in a living subject . As an extension of Jenova ' s ability to read the memories of others and shift its appearance based on those memories , this confers the donor ' s abilities , appearance , and other characteristics on the subject . The subject ' s capacity to manifest their new abilities varies depending on their mental and physical integrity . The vast majority of subjects seen in " Crisis Core " lack the same integrity as Genesis and Angeal , and thus only receive a fraction of the ability their donors have , the exact level of transference varying between individuals . Aside from transferring abilities and physical characteristics , there are two large downsides to creating a copy . Implanting the cells of the G - type SOLDIER strains the subject ' s mind , and if they are weak - willed their sense of self will break down , rendering them entirely obedient to the donor ' s mind . Subjects with a strong will maintain their sense of identity , but will still be influenced by the donor ' s mind . The subject ' s mental and physical integrity affects their degradation , as subjects who are physically weak will experience a higher rate of degradation than those who are strong . The level of degradation in the donor affects the rate of degradation in the subject ; the more degraded the donor is the faster the subject will degrade . Genesis copies . Genesis Copies comprise the bulk of the forces of the Genesis Army , and were largely created by injecting Genesis ' s cells into the bodies of 3rd and 2nd Class SOLDIER members who had allied with Genesis and deserted Shinra . The subjects imbued with Genesis ' s cells take on his facial appearance , and emulate his style of dress with red and black clothing based on Genesis ' s coat and uniform , some directly wearing replicas of his attire . Because Genesis was already undergoing degradation his state passes on to his copies , and several of them experience accelerated degradation . Genesis Copies can mutate into demi - humanoid forms . An otherwise normal Genesis Copy transforms into G Eliminator upon consuming a lock of Zack ' s hair , which contain S - cells from Project S . G Warrior , G Purgatorio , and several palette swaps of them also appear heavily mutated . Whether these mutations result from the subject ' s latent potential , degradation , Mako exposure , or a combination of these and other factors , is unknown . Because Genesis did not receive the full abilities of his own donor , Gillian Hewley , he is unable to imbue monsters with his abilities , and once he was wounded , his nature as an imperfect subject manifested in the beginning of his genetic degradation . Angeal copies . The second type of copy seen in " Crisis Core " is Angeal Copies . The monsters imbued with Angeal ' s cells do not take on Angeal ' s appearance , but instead Angeal ' s face appears grafted onto their bodies , and they take on a silver , black and gold color scheme . Angeal copies have the limited ability to sense each other and call for aid from other copies , such as how Lazard Deusericus could call an Angeal Copy in Midgar to aid him at Banora , and Angeal can summon several Angeal Copies to himself to become Angeal Penance . Only one human Angeal Copy is seen in " Crisis Core " , Lazard , who received Angeal ' s cells at an unidentified point prior to Angeal ' s death . Several years after being transformed Lazard ' s face has taken on Angeal ' s features , and his hair is white from degradation . Though maintaining his own identity , Lazard is influenced by Angeal ' s will to aid Zack in his battle with Genesis , and has Angeal ' s white wings that enable him to fly . As Angeal was born directly from Gillian and received the full weight of her abilities , he does not degrade . His copies still do , but at a slower rate compared to Genesis Copies . As with Genesis Copies , the rate of ability transference and degradation varies between individual subjects . List of Angeal copies . In addition to the types of copies listed below , there is a that appears in the Sector 5 Church and stands guard over Aerith Gainsborough after Zack leaves Midgar . This fifth copy type is never given a designation , or fought as an enemy , and is the only copy of its type to be seen . Other subjects . Hollander eventually injected cells from Project G into himself - in - game Hollander claims he used cells from Genesis , but the " Crisis Core Complete Guide " states he used cells directly from Gillian , making him a G - type SOLDIER like Genesis and Angeal , rather than a normal copy . Because Hollander is physically weak he experiences an accelerated rate of degradation , and the wing he manifests is small and sickly . If Hollander used Gillian ' s cells to transform himself , presumably he would be able to create copies from his own cells as Genesis and Angeal can . However , due to his accelerated degradation , any created copies would likely be prone to even more rapid degradation themselves , making them ineffective as warriors . The Sephiroth Clones in " Final Fantasy VII " share several similarities to the Genesis and Angeal Copies , and are called " Sephiroth Copies " in the Japanese version of the game . The Sephiroth Clones are normal humans implanted with the cells of Sephiroth by Professor Hojo , causing them to break down and lose their sense of self , becoming entirely obedient to Sephiroth . Genesis mentions that a Project S SOLDIER like Sephiroth cannot copy his traits onto others via his cells , and his body will not degrade . This is likely why , aside from Cloud , none of the Sephiroth Clones show any enhancements to their physical abilities .
