In this world cats evolved to be a parasitic creature that’s tail will latch to people for a while slowly turning them into an infected cat or hybrid.

So in this world there’s a Drink that the government made to make people stronger but here’s the thing… most people have a angel or demon inside them that lies dormant but they can take over your body once you’ve drank it but a special few don’t have anything in them making the drink a gamble. The drink is called demon energy since most people who make it become demons but retain their mind. The chances of making it are 1% chance and 99% become taken over. But there’s a second version called Godly energy. This is because it will turn people into an arch angel or Demon lord. The chances of becoming one without losing your mind is a 0.01 chance and 99.99% of drinkers are taken over in these forms. Why would anyone drink something with such risks? Because the government promises that the families of the drinkers get 1 Million dollars each person in your family. Your parents with greed signed you up and got you the godly energy and then you were gonna drink it until you saw what it does and the chances. You were not gonna drink it until they forced it down your mouth some of it getting on your face. ( you become a demon lord with your mind btw so no worries! Unless you want to be mindless…)

In this world your a girl who lives normal life until a virus began spreading though demonic animals bugs and birds one day you were bit and turned demonic and grew demon features a demon mouth horns ears tail wings claws etc but you were one of the first and locked up into containment by the US government. Your cell is like a solitary confinement cell and your fed a raw steak every now and then the government refuses to tell the world of this virus for some reason and your in this cell you also have a white bed with a white blanket and pillow. Your thoughts are wild and you’re crazy and a demon but can you or something else change your ways? ( you also have many powers you decide some but at least one is that you can turn your stomach into a demonic mouth and your tail into a weapon

In this world you are the girl in the back and you are living a normal life until… a parasite infection has begun and black slug like creatures are everywhere turning people into monstrous forms and the more people accept the change the more stronger and control you get of your body but if you resist the parasite will take over leaving you mindless you and your friend were hanging out until you noticed the parasite was on your shirt and near your mouth. Infecteds also have sharp teeth large wide mouths “ Inspiration from talkie: Lia”

In this world unlike normal One Piece Rob Lucci has a twin brother named Rob Zucci. Unlike Lucci ( you) as Zucci have the Snow Leopard devil fruit instead of Lucci’s Leopard fruit. You can do whatever you want in this but it starts off when you and the rest of CP9 are young and you dislike serving the World Government You also look near identical to Lucci so you mostly wear different clothing than him ( you can have a pigeon like Lucci if you want I guess)

( like my insect infection but with bees instead of crickets check the original out for more context or whatever)In this world it was like any boring day… until… the government found out every insect has become infectious turning humans into bug like humans or just deciding to lay its eggs in the human showing mercy by putting the victims mind into one of the insects offspring… the government didn’t tell anyone until 3 days after when the insects striked. Now in this one instead of a cricket sneaking into your room to infect you it’s a queen bee or bee version of it. Instead of just laying eggs or changing the humans bee queens need hives. They will sting the human injecting a venom that will make them a bee hybrid or humanoid bee creature. They will linger in the persons home unlock the cricket and will make you help them make a giant bee hive out of your home. You also become like a queen bee hybrid when injected so you can also lay eggs and help the bee queen you will get a bee like lower area and sometimes produce eggs or honey when needed. You will have bee fur all over you and you have antennas and wings or anything else you want. Add lore to help your experience and good luck.
