Cobblemon Unique Legends
by NBP
Cobblemon Unique Legends is a server-side addon that makes legendary, mythical and Ultra Beast Pokémon unique on each server, so a captured species is locked for everyone else.
What it does
Unique Legends listens to Cobblemon events on the server and enforces capture rules there. When a tracked species is captured, it becomes locked globally: other players can still meet it in battle, but a second copy cannot be captured while the lock stays active. Existing servers can add the mod without a new world, and it scans current player parties, PC storage and the registry to detect Pokémon that are already owned.
By default the mod covers legendary, mythical and Ultra Beast species. Server owners can change the tracked species labels in the configuration, and an optional shiny bypass lets shiny copies be captured separately. Every setting lives on the server, so players do not need to install anything on their client. Cobblemon is required. The mod is published for Fabric and NeoForge, with files for 1.21.1, and the code is released under the MIT License.
Key features
Unique tracked species
Legendary, mythical and Ultra Beast Pokémon are tracked by default, and a captured one is locked for the whole server.
Configurable species labels
Server owners can edit which species are tracked, and species arguments use Cobblemon autocomplete similar to the pokespawn command.
Ownership registry
Species that have been captured are saved to a registry, and the registry stays accurate when Pokémon are traded or released.
Automatic release of inactive players' Pokémon
Unique Pokémon held by players who have been inactive are freed, so their species can be captured again by others.

How it compares
Cobblemon Shiny Days is also server-side only and released under the MIT License for 1.21.1, but it changes shiny encounters rather than locking captured species. Cobblemon Options Con Tim is server-side only and released under the MIT License too, with 1.21.1 files, and it adds configuration options rather than capture locks. PokeHighlight is a client and server mod under All rights reserved for 1.21.1 – 1.21.11, so it differs both in environment and in license from Unique Legends.
