In a nutshell this is a world where fictional characters are brought to reality and we see how the world reacts as more fictional characters get brought to reality , from just the characters to the monsters to the diseases etc.
In a world where the boundary between Fiction and Reality has been broken , where countless fictional worlds converge into one.
This world that I created , a result of perhaps boredom and ADHD , a world where fiction bleeds to reality , as the boundary between what is fiction fades and they start to appear on this earth , this world I created , it is a mix of the SCP foundation , where instead of Anomalies , we have "Remnants" beings whose powers come from the world of fiction , instead of their strength and weaknesses being unknown , they are vastly known , for they are fiction turned to reality.
However, to make it less confusing , I only take the Concept of their powers , so instead of it being a full list of a fictional character's powers , I merely take the concept of it , for example Luffy's entire power revolves around being rubber and having "Toon Force" that turns reality into a fictional cartoon like world that he can manipulate , Superman for instance will have the power of a Kryptonian , Bronya from Hi3rd would be able to create constructs and so on.
The requirements to allow a character to be brought into this world of mine are as follow :
1. There must be a canon lore for the character , on the occasion of a character having multiple lores like those from DC , Marvel , or vocaloids , it'll be shaped based on the general consensus of the character
2. The powers of said characters are basically the concept of their powers , not the full load of their powers as if I were to do that it would overwhelm me for main characters are often loaded with complicated skills.
3. I must add a character whose lore / power I understand enough , this is to prevent 2 things , defaming the original and also escaping the wrath of fans.
4. They must have an impact from the fictional world they come from , as such beings who only act as powerful or mighty background Gods that have no impact , or joke characters from slice of life fiction aren't included
5. There can only be a single instance of a character with the exception being Echoes [Those who only have a fragment of their power] , meaning if there were to be an injustice superman , there would not be another version of superman until the original superman dies. An exception to the rule above are Expy's , for example the character Bronya from Honkai Impact 3rd , Gun Girl Z and Honkai : Star rail , that would mean all 3 of them could exist in this world of mine , for they are not considered 1 even if they are in technicality the same.
6. It must not be from fan-fiction or original novels from websites like Scribble hub , Webnovel , RoyalRoad , etc. Unless explicitly stated that it's allowed (This is to prevent copyright stuff n co ) , only from an official / officially translated novel / manga / Animated series / Comic
7. While this one would not have an impact on the story , in my eyes all the characters appear in an anime-like style drawing for that is what I know and I remember
8. There is a hard limit of 5 Echoes / Paradoxes / Vestiges per fiction [A total of 5], right now those that have reached the max are from from HSR [The Herta , Cipher , Silverwolf , Firefly & Sparkle [Paradoxes] ] An exception to this rule will be Amalgamations like the Raiden's and Elysia's of my world
The reason behind the one above is that as more characters from the same fiction appear, that specific world weakens until they can no longer send another character from their universe. While there is a 5 limit cap for characters from each worlds , some things exists in so many fictional worlds that we can assume that there can be thousands to millions of specific things which are :
a. ) Fantasy Races [Elfs , Dwarves , Dragons , Dragonoids , Goblins , Demons , Angels , Merfolk , Fairies , Beastman / DemiHumans , Vampires , Undeads , etc.]
b. ) Magical Girls [Most all types of Magical girls work the same way so ye]
c. ) Mana / Magic [Literally all forms of magic used by manipulating Mana.]
d. ) Ki / Qi / Chi Manipulation [You see this in a lot of wuxia / martial fiction Things like Gu , Chakra , Haki are included here. Some more specific examples would be Aura , Prana etc from Manwha's like Survival Story of a Sword King]
e. ) Elemental Powers [Yes. elements like Fire , Water , Space , Time , Death , etc. Things like Visions & Delusions from Genshin are included here]
f. )God like beings [Most Depiction of Greek / Egyptian / Norse / Chinese / Japanese / (Yeah You get what I mean) Gods including Constellations (The ones we see in ORV , SSS-Class Suicide Hunter etc.) ]
g. ) Monster Tamer type [Those that can tame monsters or the such like Pokemon , Digimon , Some Fantasy Races]
h. ) Fate / Intuition Type powers and the such [Battle Senses , Prophecies , Divination and such]
i. ) Manipulation of atoms / molecules and the kind
j. ) Futuristic Races [Cyborg , Automatons , etc.]
A few examples of unique ones would include : Honkai Energy from Hi3rd , Originium from Arknights , The depiction of Pathways from LOTM , Some may argue why do you consider Originium and Honkai as unique because their lores are in depth and can be used in creative ways.
For example the usage of Honkai Energy's allowing specific Herrscher authorities even if their names are simple , ex : Flame , allows the acceleration of atoms and the such , Originium? Do I need to explain its lore? Other examples include Echoes from WuWa , Stands from Jojo's Bizarre Adventure , The Depiction of Fables from ORV and the such.
