They Changed Forms
by MrLambert
They Changed Forms is a Forge mob mod in which a supernatural disease spreads through the world and turns other creatures into infected forms.
What it does
Parasites in the mod infect other mobs and drive them to attack, so an ordinary encounter can turn into a fight with changed creatures. The effect is meant to feel unsettling, with mobs that behave in ways the vanilla game does not show. Geckolib is required, and the mod runs on the client and on the server, so both sides need it. Files exist only for Forge 1.19.2, with a single 1.0.0 release dated 2024-01-01. The mod is distributed under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license and is not open source.
Key features

What the author says
This mod is about dangerous lil parasites that infect other mobs and do horrible things to them, to the point where you almost feel bad if these mobs didn't try to claw your face off. this mod is very early in development, bugs are to be expected. but i try my best to fix them.
