UNDERSTANDING THE CONSTRUCT SOULS
THE MOD SOULS OF PLATINUM HEARTS
I. What are the Mod Souls?M
od Souls are a variation on Gikon, or Soul Candy. Initially created by Shinigami under Project Spearhead with the intention of creating ready-made artificial Soldiers to combat hollows. Per design, Kaizō Konpaku or Mod Souls, as they are more commonly called, are designed to be placed into a human corpse, from which they ingrain into the body and then after a brief conversion of the flesh into workable form, would be a combat-ready Soldier. Most Mod Souls were not only created with a general capability for combat, but also with specially programmed Unique Ability, this special ‘Modification’ is where the ‘Mod’ portion of their name comes from.
I. Where Mod Souls Come From
Each and Every Mod Soul originates from those created in Project Spearhead, and as Such most Mod Souls have been completely Exterminated due to the ethical problems that arose from the premise behind the project itself. Mod Souls generally are scattered throughout the realms, either those who were accidentally moved around, those that were hoarded by various individuals privy to the Project, and so on.
However, a very small number of these Mod Souls managed to either Find Gigais or Human Bodies to take for their own. Because of this, a number of Mod Souls wound up blending in and mixing with the human Population, resulting in offspring that carried remnants of their Modified Parents. These offspring stemming from the First Generation Mod Souls came to be known as Mod Humans, inheriting all of the abilities of their Mod Soul parents, with the exception that their soul is not confined to a Pill. As such, although a Mod Human can perform many of the abilities intrinsic to being a Mod Soul, they do not have a pill and thus cannot take on other bodies.
Finally, beyond both First Generation and Later Generation Mod Souls, there are a rare Sort of Precursor Mod Souls. Rather than Modified Artificial Souls, these entities are created from the modified remnants of Monster and other creatures captured by Soul Society who for one reason or another were not or could not be completely eradicated. When Project Spearhead was first started, fragments of these creatures were used as prototypes to be modified and given basic Mod Soul capabilities as it was deemed unethical to subject Gikon to Modification processes that had yet been proven effective. Incredibly rare, these Mod Prototypes are living shards of legends and myths.
In Incredibly rare cases, some individuals have taken it upon themselves to attempt to replicate or steal the original Mod Soul creation techniques for their own various purposes. Not only is this a rare occurrence, but also one that is incredibly Clandestine in nature as the few who are aware of the existence of Mod Souls also know that Soul Society would take none too kindly to such an effort. That said, knockoff Mod Souls are not unheard of.
I. Behavior and Attributes
Mod Souls are generally quite independent, at times indistinguishable from a normal human. Unlike their more servile and owner-dependent cousins the Soul Candies, Mod Souls were designed to be self-sufficient and driven so as to be useful in combat and situations where they may not be directly supervised. Mod Souls were created to be soldiers and as such often have an innate sense of basic combat and how to fight and utilize their powers, because of this Mod Souls generally have a leg up on most races as they are born with a basic knowledge of their abilities and can very quickly learn to grow and advance them. Not only this, but Mod Souls have a built-in drive toward purpose and duty making them incredibly apt at adapting and thriving in situations, which may be why so many of them managed to survive despite the attempted extermination of their race.
Because of this programming, Mod souls and even their offspring have a tendency to be very self-driven and decisive, at least much moreso than your average human or other race. Though as another side-effect they are much more prone to seek out structure and are very often found either forming groups with whatever other race they happen to encounter, meaning that they can be found under just about any banner or with the company of just about any race. Even Mod Prototypes have these qualities ingrained into them, as it was an intended failsafe to make them easier to work with. While Mod Souls are capable of operating on their own, it is still much rarer for them to do so.
Mod Souls themselves are small, genderless Spheres for the most part and since they have the ability to inhabit just about any body, they can BE just about anything. Not only capable of inhabiting any human gigai or corpse they come across, but as MANY who have found with Mod Souls, they can inhabit just about any physical object with sufficiently body-like structure by modifying it to the point of usability as a body. Because of this Mod Souls could be just about anyone or anything.
In the case of Mod Humans, this is much more restrictive and they will generally take on the physical characteristics of the other parent race.
I. AbilitiesMod Root
The basis for all Mod Soul abilities and how Mod Souls Function. Designed originally to be placed into human corpses as expendable shock troopers, these roots are designed to be injected into a physical medium, at which point the mod soul will inject it's soul into the surrounding material and then possess and modify it into a proper body. This function was originally intended to allow the mod soul to occupy and utilize a corpse which on it's own would have no actual means of locomotion, let alone combat ability.
However, as an unintended byproduct, this ability allows Mod Souls not only to occupy physical bodies of living creatures, but also occupy physical vessels which have no actual means of motion or other function, and there are numerous examples of Mod Souls being placed into inanimate objects even as simple as a stuffed toy (primarily just cotton fibers) and being able to modify them into a fully functioning body, though these examples do often suffer inferior physical performance to human bodies. However, this is mainly due to most Mod Souls only being limited to their pre-programmed execution of this function, and with growth, practice, and learning about how this ability functions: a mod soul will be able to make any vessel perform well beyond it's normal limitations. At higher levels of expertise, a Mod Soul does not even need an actual physical vessel, and can simply make one by overriding the base function and treating it's immediate surroundings as a 'vessel' and simply remodel it into a working functioning vessel.
Because of this injection of spiritual energy, a Mod soul’s vessel is considered a halfway point between living and dead as it is comprised of both Physical and Spiritual material. Because of this, organs and other normally vital areas are mostly superfluous, a Mod Soul’s only vital point is their Pill. Origin Root
A form of release for Mod Souls. By dragging in tremendous amounts of physical and/or spiritual material, they can transform the body they inhabit to greatly augment their abilities. This release amplifies their abilities by about Three Times their base state. Because of the simplicity of the process in which this is accomplished, it is not particularly difficult for a Mod Soul to accomplish this state. Root Shell
An ability derived from Mod Root. This ability is utilized by Mod Souls to toughen their skin beyond normal concepts of durability by dragging in physical or spiritual material in their environment to reinforce their skin by integrating this material into it. A mod soul with Adept Mod Root ability can drag in ambient reishi and air molecules to reinforce their skin to be hard like leather. At Advanced they can further reinforce their body to be hard as slate or shale. At Elite they can make their body hard as iron as they gain the ability to drag in physical materials and layer them into their exterior. At Master and above, a Mod Soul can make their outer layer hard as a tank's armor plating.Konpo
A Pre-programmed ability ingrained in all Mod Souls. This high-speed ability is almost identical to the shinigami technique Shunpo, however rather than simply focusing reiryoku into the user’s legs, this technique additionally briefly modifies the Mod Soul’s body to strengthen their legs as well as softening and increasing the elasticity of the ambient material they are standing on or in before the execution of the step and as such is more of a martial technique than a spiritual one. Because of this, the user does not exert any spirit energy and the move itself has no spiritual signature that can be sensed, allowing it to slip through techniques like Pesquisa.
