Hi. I really love your au because it has all that fun body horror apocalypse stuff while staying away from grimdark "humanity is the real monster" type stuff while also showing the horror of person identity changing. V good. May I have some worldbuilding, or literally anything that won't compromise plot? Also what's the update schedule? Is it monthly or every 2-3 weeks?
Hmmmm lemme think... Ok!! Since I have been dm'd about OC's (which. Wild. I'm famous enough for people to make OC's for my universe) I've come up with a rough set of guidelines for mutations.
There are Two kinds: Animalistic and Not Animalistic (scientific, I know).
Inanimate is a person growing into a tree, slowly turning into metal or stone, and is generally the most unfortunate of the two. The Slug fits into this category as it's a living stomach/mouth and not any particular animal. People could also end up as sentient piles of goo, incredibly hostile pieces of architecture, with the only through line being that they manage to keep at least one defining human characteristic. I.E eyes, a face, a mouth somewhere, That Tree Is Bleeding, a lot of hands, etc etc
Animalistic is far more common. This is your Phil, your Techno, your Tubbo. Your gazelles the Wolf and the poor pizzeria employee. They are a mix of human and animal, animal and animal, and animal and animal and animal and animal. It is very rare for you to become just a straight up perfect animal. There aren't any people wandering around as a fully functional horse. There's always something fucked up about them i.e extra eyes, antlers/horns, multiple limbs, wings, scales, fur, teeth, etc etc. They are overall the more hostile ones, and will often form "packs" as one person half mutated is more likely to spread similar mutations whether then just the virus. The Unique people (Phil, Techno, Squid when I figure a way to write him in) were all infected very early, and then stayed contained/alone for the majority of their transformation. Other people ended up copying others.
This copying can happen with Inanimate mutants as well, but is much rarer as Inanimates tend to not move much, so you could just. Walk out of their contagious sphere. idk if I'm using that word right or if any of this made sense.
As for the update schedule... Uh... Whenever the next update is done, I guess? I try to have at least one chapter out each month, but that's about it. Leans towards the end of the month tho.
Thanks so much for letting me ramble! I hope this was interesting enough a read to justify it's length
