Pathogen : monster plague
Pathogen : monster plague adds a corruption that spreads through the world, turning vanilla biomes and mobs into mutant versions for Forge on 1.20.1.
What it does
The mod introduces roughly 90 unique mobs, including corrupted forms of vanilla creatures and biome-specialized mutants with alpha variants. Infection is a mechanic here: it changes the inhabitants of a world into bloodthirsty mutants, and a cure mechanic is included as well. Corruption spreads through three underground caves tied to mesa, swamp and jungle biomes, two corrupted surface biomes, and a corrupted end and swamp, with more biomes planned for later.
Cave variants lose their pigment and grow filaments that sense movement, and they can blind prey. Mesa mutants are bulkier and absorb heavy damage, while swamp mutants carry fangs and venom that inflict poison and nausea. Mutants differ in stats, abilities and resistances.
The mod also adds a set of weapons and armor with unique abilities. Pathogen requires Geckolib, which must be installed alongside it. Every player and the server need a copy of the mod. Files are published for Forge on 1.20.1 only, and the code is all rights reserved, not open source.

How it compares
Infection Of Unhuh is a Forge mod for 1.20.1, client and server, under All rights reserved. A Corrupted Place is a Forge mod for 1.20.1 with the same environment and license. The Mutant Mobs Mod covers 1.19.2 – 1.20.1 on Forge and is also client and server under All rights reserved, so it is the only alternative that reaches an earlier version.
