Angeal Copy
Subjects of the copy technique where Angeal’s cells were used. Within the game, this includes a variety of monsters and Lazard. When using monsters as the subjects, they were unable to take on Angeal’s form, and instead an image of Angeal’s face appeared to be grafted to a part of their body. Incidentally, though not all of the Angeal Copies that appear in the game are monsters, Angeal’s cells were used primary to make copies from monsters while Genesis’ cells where never used to make copies from monsters.
Furthermore, Angeal Copies do have an ability to call to one another, but they can only have a general understanding of each other’s situations. An example of this ability is how Lazard was able to coax the Angeal Copy living in Aerith’s church to come help him in Banora.
Copy Technology
Technology which, by transplanting the cells of a G-Type SOLDIER into a physically strong subject, copies the donor’s abilities, appearance, and characteristics onto the subject. However it does not always yield perfect results, and differences in appearance and ability may arise based on the subject’s latent potential. For example, the reason the Genesis and Angeal Copies in the game seem weaker than their originals is due to the subject’s latent potential being inferior to the originals, and are unable to fully utilise the abilities they received.
The influence of the copying process also extends to the subject’s mind, and if the subject’s will is weak their will is completely taken over by that of the cell donor and leads to the breakdown of their sense of self, like the SOLDIER operatives who become Genesis Copies. Conversely, if they are strong willed, they can maintain their identity while still being influenced by the will of the cell donor, such as Lazard as an Angeal Copy.
Genesis Copy
Subjects of the copy technique where Genesis’ cells were used. Though they are all humans their individual differences become more prominent during the process, as seen with the G-Assault and the G-Warrior, showing how an individual’s latent abilities can become integrated into the changes in form and strength that takes place during the copy process. The rate of their degradation also varies from individual to individual, along with influences from the state of Genesis’ cells, and thus his own degradation quickens the degradation of all Genesis Copies.
Hollander’s Degradation
During the scenes in Gongaga Hollander’s degradation is revealed, because he used the same cells [from Gillian] he had originally transplanted into Genesis, and thus converted himself into a G-Series SOLDIER. The reason why his degradation is progressing at a remarkable rate and why his one wing is so small is because he does not have the same physical strength as Genesis.
SOLDIER Degradation
A symptom of a particular flaw inherit within the G-Series SOLDIERs and their copies. It is due to an imperfect integration of Jenova cells into their bodies, and the symptoms worsen as their genetic information is spread to other beings. The first signs of degradation are changes in skin quality and hair color, and as the body’s natural immune system is damaged the subject’s skin and muscle tissue begin to degrade. Furthermore, the subject looses their ability to restrain themselves from giving in to brutal outbursts, which can temporarily raise their skills in combat, but they run the risk of eventually devolving into monsters.
G-Type SOLDIER
Those created by Project G, and used to refers to Angeal and Genesis (in a broader sense, it also includes Hollander, who had applied the same treatment to himself during the game).
The Copy ability they possess is the influence of Jenova’s own abilities to convert its target into a monster by implanting it with a virus it generates within its own body, and to mimic the form of people the target knows through reading their memories and emotions. However, as the Jenova cells are not fixed in their bodies, a G-Type SOLDIER will succumb to degradation symptoms as time passes.
S-Cell
Jenova cells which Hojo treated with a special process for use with the Sephiroth Copies. From the initial “S” and the fact that the cells are used in the Sephiroth Copy experiments, it is surmised that they are related to Sephiroth’s own cells. Within the game, Genesis believed that his degradation can be halted if he obtains these cells and injects them into his body, but in actuality when a Copy took in the cells, rather than being cured, the process is sped up. However, the cells used then were Zack’s, and it was not attempted with Sephiroth’s pure S-Cells or Cloud’s, which were considered pure.
One Black Wing
The wing which Genesis has on his left shoulder in this game, and which Sephiroth has on his right shoulder in “FFVII” and “AC”. The mechanism behind sprouting the wings remains unexplained. According to the development staff, the wings were made black based on the notion of good and evil.
Genesis Army
An army formed by Genesis, Hollander, and Lazard, and comprised of Genesis and Angeal Copies. It was based out of Banora and Modeoheim. The people who were turned into Genesis Copies were those who Genesis took with him during the Mass SOLDIER Desertion.
Genesis Copy (don't ask me why there's two definitions of this in the same collection)
Copies created with Genesis’ cells, utilising the Copy Technology. Just as humans each have individual differences in their growth, so too do Copies. Depending on the latent potential of the subject changes will arise in the abilities and appearance they gain, for example with the G Assailant and G Warrior. Likewise, there are individual variances in their degradation, but this is also largely influenced by the condition of Genesis’ cells, and when his cells themselves have degraded, the speed of degradation for all Genesis Copies is also sped up.
Jenova
The “life form excavated from the earth” mentioned in the “Ancients Project Outline” document in Scene 03-18 refers to “Jenova”, an intelligent life form known as the “calamity from the skies” which crashed into the Knowlespole on a meteorite approximately 2000 years before. Jenova has an instinctive drive to destroy planets, and utilising its abilities to inject a virus into its target and transform them into monsters, and to mimic other forms according to its opponent’s thoughts, it drove the Ancients to near extinction. It was later sealed away by a counter-attack by the Ancients, and remained dormant in the ground until it was exhumed 30 years ago.
Its relation to Sephiroth is like that of a parent and child, and in “FFVII” it continued to work with Sephiroth to summon Meteor and destroy the planet. After the final battle it was defeated by Cloud’s team and lost its physical body, but its mimetic legacy lived on within the Lifestream, and in “AC” it created remnants such as Kadaj.
Jenova Cells
The cells from Jenova used in the Jenova Project and SOLDIER surgical procedures. Those who have been injected with these cells undergo physiological changes such as improvement of their physical abilities and partially receiving Jenova’s abilities. However, mentally weak people are unable to withstand Jenova’s will, and it sometimes brings about mental abnormalities.
Jenova Project
A project started by Gast approximately 30 years previous, when Jenova was excavated from the earth. This project, also known by its other name of the ‘Ancients Project’, involved using cells from Jenova to artificially create a new generation of Ancients, with the ultimate goal being to make them search for the Promised Land. Project S and G are part of this same project.
This project was started under a fundamentally mistaken idea, that Jenova was an Ancient. When he realised this, Gast quit his post and disappeared from Shinra.
