CobblemonBahaviours
CobblemonBahaviours changes how wild Pokemon act in Cobblemon 1.21.1, so some of them hunt nearby players instead of staying passive.
What it does
Wild Pokemon spawn with a behavior chosen at random: by default about 5% become aggressive and 10% become timid, while the rest keep the standard passive behavior. Aggressive Pokemon actively hunt players within a range of 16 blocks by default. Timid Pokemon flee from players detected within 10 blocks by default, and higher levels make the fleeing faster.
An aggressive Pokemon attacks using its actual moveset, so damage follows the move's power and the Pokemon's stats and accuracy. Moves with secondary effects apply them, for example burns that set fire, paralysis that slows, and poison that applies the poison effect. Attacks spawn particles matching the move type, such as fire particles for Fire moves. Higher levels from 1 to 5 add more damage, faster attacks and shorter cooldowns.
The mod is server-side only and is licensed under the MIT License, which means it is not open source. It is published for Fabric and requires Cobblemon for 1.21.1, the only game version it targets, with the latest file dated 2026-03-12.
Key features
Aggressive hunting
Aggressive wild Pokemon seek out players within range and attack them, rather than ignoring them.
Moveset-based damage
Attacks use the Pokemon's real moves, with damage, accuracy and secondary status effects taken from those moves.
Timid fleeing
Timid wild Pokemon run away when a player gets close, with faster flight at higher levels.
Type-matched particles
Each attack spawns particles that match its type, so a Fire move looks different from a Water move during a fight.
Level scaling
Pokemon at levels 1 to 5 deal more damage, attack faster and recover sooner between moves.

What the author says
It's a server-side Fabric addon for Cobblemon (1.21.1) that makes wild Pokemon feel alive by giving them aggressive and timid behaviors. In short: it turns wild Pokemon from passive decorations into dynamic encounters — some will chase you down and fight using real moves, others will run away when you approach.
