Cobblemon Outbreaks
by Raguto
Cobblemon Outbreaks adds Scarlet and Violet style mass outbreaks to Cobblemon, where one species appears in waves across a chosen area.
What it does
An outbreak targets a single species and advances through a configurable number of waves, each with its own spawn range. Species are chosen by the biome or location where the outbreak starts, and optional filters can restrict biomes by tag or ID, or blacklist tags entirely. An anti-repeat option lowers the priority of species used recently, so outbreaks do not keep returning the same Pokémon.
Outbreaks can start automatically on a timer with a configurable duration, or be started by an admin with a command. Shiny odds rise as players defeat and capture more outbreak Pokémon, and the base rate and progression thresholds are configurable. Boosts for outbreak Pokémon, including perfect IV settings, IV floors, hidden ability and egg move chances, can be set in the config. The mod requires Cobblemon and Fabric API and runs on the server only, so players join without installing it. It is released under All rights reserved and is not open source. Files are published for Fabric and NeoForge, with version 1.1.2 for 1.21.1 as the latest file, dated 2026-04-05.
Key features
Mass outbreak events
A single species spawns in large numbers across an area, with waves that escalate over the course of the event.
Biome-aware species selection
The species that appear depend on the biome or location where the outbreak begins, and datapack species are supported.
Shiny progression
Shiny odds increase as more outbreak Pokémon are defeated or captured, with configurable thresholds.
Bossbar and announcements
A server-side bossbar shows the species, wave and shiny rate, and global messages can announce spawn, start and end, with optional clickable coordinates.
Distance cleanup
Cleanup controls remove outbreak Pokémon that drift too far, keeping events contained and the server responsive.

How it compares
Cobblemon EXP Bar is client and server, under the MIT License, not open source, and covers 1.21.1 – 1.21.11 on Fabric and NeoForge. Cobblemon Go Catch is also client and server under the MIT License and not open source, but covers only 1.21.1. Cobblemon Outbreaks is server-side only and released under All rights reserved, so it differs from both in license and in what players must install.
