What it does

ShadowedHearts is a side mod for Cobblemon that brings the Shadow Pokémon of Pokémon Colosseum and Pokémon XD into the game. Shadow Pokémon carry Shadow Moves, and their access to those moves stays closed until the Pokémon is purified. A Heart Gauge tracks each Shadow Pokémon's progress, with Hyper Mode and Reverse Mode affecting how the gauge behaves during battle. A Call button, Snag Machines and Relic Shrines add ways to obtain and interact with them, and a Purification PC with Flow Tempo mechanics handles the purification process itself. Snag Machines are limited to player-versus-environment battles.

Many systems follow the original GameCube implementations closely, and the mod builds on the modern Cobblemon base while keeping the feel of those games. Most behavior can be changed through configuration, in singleplayer worlds and on multiplayer servers alike. The mod requires Architectury API, Cobblemon, Forge Config API Port and Special Model Loader. Accessories, Radical Cobblemon Trainers and SimpleTMs: TMs and TRs for Cobblemon are optional. It is published for Fabric and NeoForge on 1.21.1 only, and it is not open source, since it is licensed as All rights reserved.

Key features

  1. Shadow Pokémon purification

    Shadow Pokémon can be purified through a dedicated system, which ends the restrictions placed on them.

  2. Heart Gauge mechanics

    A Heart Gauge tracks the state of each Shadow Pokémon, with Hyper Mode and Reverse Mode changing its behavior.

  3. Shadow Moves

    Shadow Pokémon use Shadow Moves, which cost heart progress, and their use is limited until purification.

  4. Relic Shrines and Snag Machines

    Relic Shrines and Snag Machines provide places to obtain Shadow Pokémon, with Snag Machines limited to player-versus-environment battles.

  5. Configurable rules

    Options cover how closely the mechanics follow the original games, for singleplayer and server play.

What the author says

Cobblemon: ShadowedHearts brings Shadow Pokémon from the GameCube-era classics Pokémon Colosseum and Pokémon XD: Gale of Darkness into Cobblemon. Shadow Pokémon wield powerful Shadow Moves, but at a cost. Their hearts are closed, limiting move access and behavior until they are purified. ShadowedHearts faithfully…
