Concept: Fusionism
Fusionism is a subcategory of Unique Attributes, mainly associated with two beings, be it mortals, Gods or Demons, fusing with each other into one being, subsequently combining their attributes, from strength and speed, to reflexes, intelligence and wisdom. When done correctly, this new being will possess an astounding level of power, far beyond what either fusees would have possessed individually, even at their most powerful forms. Even the weaker methods of Fusionism causes the fused being to be at least ten times stronger than the sum of their fusees. Due to how they operate, all of the variants are Koyoshiki in nature.
Generally, the various methods of Fusionism are divided into three tiers, as shown below:
<Tier I: Regular Fusionism>
These Fusionism variants are on the level of Tier I Unique Attributes.
Anti-Crisis Energy: The fusion between the wielder and their many possible alternate world counterparts. This form of fusion is named as such, as it is mainly facilitated through the suppliance of Anti-Crisis Energy, the energy that connects people through memory and history. This variant of Fusionism grants the wielder the most diverse skillsets compared to other variants.
Arcana: The fusion between the wielder and a God associated with a certain Arcana Tarot. Some extremely proficient wielders can fuse with all 22 Tarots, such as Nyx.
Armatus: The fusion between the wielder and a Seraph. Grants enhanced levels of control over one of the four major elements, with the element depending on the Seraph's affinity.
Avatara: A fusion exclusive to certain Elemental Masters, particularly the titular Avatars, who have the full mastery of the elements of Fire, Air, Water and Earth. This Fusionism type involves the Avatar being assimilated with the skills and experience of the previous Avatars, while being supplanted with a massive amount of Cosmic Energy, drastically improving their elemental abilities and fighting experience. Unlike other types of fusion, this fusion is more a spiritual one than a physical one.
Beast Seal: The fusion between the wielder and a Youkai, which includes beings like Nine-Tailed Foxes and the Ushi-Oni. Wielders of this form of fusion are granted a special Trump Card in the form of the Baryon Mode, that fuses both the wielder and the Youkai's Ki into a new form of energy, drastically improving their capabilities, albeit at the expense of both of their lifespans.
Daemon Masquerata: The fusion between the wielder and a low-level Demonic Being, mainly used by Witches. It grants the witch the ability to use said Demon's powers in both direct combat and traversing the world. This form of fusion is often considered as forbidden, being a highly difficult technique requiring immense amounts of physical and magical energy, and perfect emotional synchronisation between the Witch and their respective Demon.
Djinn Equip: An evolution to Daemon Masquerata, involving the fusion between the wielder and a Great-level Demon, such as any of the Demons of the Ars Goetia, or any Demon of their level. Wielders of this form of fusion are granted a special Trump Card in the form of Extreme Magic, a spell representing the pinnacle of the Djinn's Magic Type, capable of widespread destruction on a massive scale.
Madness: The fusion between the wielder and a Clown of Madness, special clowns that are the very embodiments of the contagion of madness and the physical form of fear itself. This form of fusion is often referred to as the most demented one, often twisting the wielder into unimaginable shapes, and turning them into walking cognitohazards that radiate an aura of pure fear and terror wherever they go.
Omega: The fusion between a wielder and at least six beings of a similar race. This makes the wielder ten times stronger than before, a minor surplus of power. Additionally, the wielder can not only utilise all of their fusee's powers, but have enhanced level of control over Negative Energy, similar to the Sorcerors.
Teigushin: The fusion between the wielder and a Teigu, the general term for any mythical-tier weapons. It is essentially the ultimate evolution to Heavy Metal (Sword) and Essence of a Weapon. Teigushin grants the wielder different attributes depending on the type of weapon, but they will always possess a Trump Card of varying effects.
<Tier II: Advanced Fusionism>
These Fusionism variants are on the level of Tier II to III Unique Attributes.
Belyudra: A unique form of Fusionism shared by Archdemons and their evolutionary successors. This ability allows the Archdemon to merge with countless Kaiju, letting them take upon a giant, demonic form with massive firepower and durability. However, there is one weakness, where the various monsters can be controlled into rebelling, immobilising the giant and making it more vulnerable. It is the famed technique of Belial.
Deus: The fusion between the wielder and an AI God. It is stronger than its fusees by fiftyfold. It has a trump card in the form of the Super Deus Mode, which raises the multiplier to 999.
Esoterism: A unique form of Fusionism shared by Archdemons and their evolutionary successors. This ability allows the Archdemon to merge with a powerful Archetype, not only being granted the exponential increase in power most Fusions have, but also being able to perpetually inflate in power even further. However, it does have a condition, that being the approval of at least three other adjacent Archdemons.
Rengeza: The fusion between the wielder and a God Tree (an amalgamate of the corpses of multiple Gods condensed into a tree). The wielder stands atop the God Tree's flower, and are granted complete control of the tree, allowing them to use its roots and seeds to attack. Additionally, they obtain a Rinne-Sharingan. However, a small weakness is that since their body is one with the God Tree, they can feel any damage done to the God Tree on themselves.
Spirit Magic: This attribute is more diverse than other Fusionism types, but ultimately still involves it first and foremost. Spirit Magic mainly involves the wielder summoning and fusing with nature spirits, inheriting their elemental powers. Beyond this, they can also tap into the ambient energies of the natural world, transmute themselves into a pure weapon, or generate a field that enhances oneself while diminishing the power of others. Additionally, Spirit Magic can also be used to enhance the wielder's other Magicks.
Spirituality: An advanced variant of Spirit Magic, with the wielder now being able to fuse with even the likes of the Godheads and the Cosmos. Unlocking Spirituality requires the Spirit Magic user to undergo many harsh trials to evolve and develop new breakthroughs, on top of having a better communion to the higher powers.
<Tier III: God Fusionism>
These Fusionism variants are on the level of Tier IV to V Unique Attributes.
High Divine One: The near-pinnacle of Fusionism, also known as Fusion Resonance. A mighty attribute possessed to those who have absorbed countless other divinities and entities, or are massive Hive Minds of Divinity. They possess an unparalleled power to absorb almost any attack or being that comes their way, except for things which are overwhelmingly more powerful.
Perfect Hybridisation: An attribute exclusive to the Hybrid Gods, and by extension the 3rd Singularity Riser, and a fusion of both Esoterism and High Divine One. This attribute indicates a fusion not only of an immense scale, but a fusion down to a conceptual and archetypal level as well, absorption, fusion and transmogrification of not merely souls, but entire concepts as well.
