Nebula: Parasites
by Energon
Nebula: Parasites introduces parasitic monsters that spread infection through early-stage crudeform forms and transformed creatures, with a nine-phase evolution system.
What it does
Parasites in the mod infect other creatures and can pass the infection through the air. A parasite standing close to an uninfected entity may infect it even when the two never touch. Infected cows, pigs, sheep and zombies appear as transformed entities with reduced maximum health, and the crudeform small and medium forms mark the early stages of the infestation.
The mod is an early development build, and the author notes that the current version covers only the first parasites while later phases are still in progress. Infestation behaviour and evolution pacing can be adjusted through configuration files, so server owners can tune the mechanics to their gameplay. A simulated player model is also present as a test, with a planned goal of inheriting a player's skin in future versions.
Installation needs Forge for Minecraft 1.21.5. The server and every player need the mod installed. It is released under All rights reserved. Its only published build is version 0.1, dated 2025-04-19, on the beta channel.
Key features
Airborne infection
Infection can spread through the air from a parasite to nearby entities, without any direct contact.
Nine evolution phases
Parasites move through nine evolution phases, so an infestation grows stronger as it advances.
Infected creatures
Cows, pigs, sheep and zombies can become infected and appear as transformed entities with 10 less maximum health.
Crudeform stages
Crudeform small and crudeform medium forms represent the early stages of a parasite before it develops further.

What the author says
This mod introduces dangerous parasites that seek to consume all living things. It all begins with a meteor crash - soon after, the infection starts spreading around the impact zone. Creatures near the site become twisted, horrifying parasite variants. As time passes, the parasites grow stronger, increase in number…
