Discord: join the official Cobblemon server, check mods-and-plugins → CobbleBrain.

About

CobbleBrain is a mod that gives Pokémon a “brain,” allowing them to think, talk, and interact dynamically with the world. It integrates artificial intelligence into gameplay, making your companions talk to you, react to battles, protect you from mobs and even cook a delicious steak — all using your prompt.

Wild Pokémon are also capable of interacting with the player and the world, creating quests, remembering your actions, and even organizing raids if you become their enemy.

Features

• Pokémon can talk to the player and to each other using AI.
• Pokémon can perform actions such as attacking, eating, cooking, repairing tools, growing plants, and more.
• Dialogue influenced by friendship, nature, past interactions, and world conditions.
• Wild Pokémon quests and karma system that react to your actions.
• Raid events triggered when Pokémon species become hostile toward you.
• Fully customizable AI prompts, behaviors, and gameplay settings through the Mod Menu configuration screen.
• Supports cloud AI models (Google AI Studio, OpenAI, OpenRouter, Player2) and local models via LM Studio and Player2.
• Multiplayer compatible, with each player managing their own AI processing.

Wild Pokémon Systems

Wild Pokémon are no longer passive. They can interact with the player and react to how you treat their species.

Quests

Wild Pokémon may approach you and start small quests, such as:

• Item Requests – bring a specific item to the Pokémon.
• Advice Requests – answer questions and influence your reputation.
• Battle Requests – defeat a specific Pokémon in battle.
• Lost Item Requests – find a treasure barrel with the help of the quest tracker

Completing quests may reward the player with items or gifts.

Karma System

Each Pokémon species tracks your behavior.

• Killing Pokémon or failing quests lowers karma.
• Helping Pokémon increases karma.

Karma influences how Pokémon react to you in future interactions.

Raids

If your karma with a species becomes lower than -8, that species may organize a raid.

A raid spawns multiple Pokémon that will attempt to defeat the player.

Worse karma = stronger raids.

To disable raids, go to the mod settings and turn off schedule raids.

How to Play

You can choose to play using cloud models or local models.

A. Cloud Mode (Recommended)

Cloud mode uses external AI providers to process dialogue.

1. Player2 App (recommended)

• Install the Player2 app and create an account.
• Run Player2.exe (the app)

Player2 includes a free amount of energy, which can be replenished daily using a spinner. You can also choose the AI model that best fits your needs. In general, more expensive models are smarter.

Here is a youtube tutorial!

2. Other Providers (Google AI Studio, OpenAI, OpenRouter, etc.)

• Create an account with the provider.
• Generate an API key.
• Choose a model (examples: gemma-3-12b-it, gpt-4.1-mini, anthropic/claude-3.5-sonnet).
• Open the mod config Menu and fill:
  • apiKey
  • apiBaseUrl
  • aiModel

Here is a youtube tutorial!

B. Local Mode

Local mode allows you to run models directly on your machine using LM Studio or Player2.

See the CobbleBrain GitHub README for detailed setup instructions.

How to Trigger Actions

Encourage Pokémon through chat to perform actions or use the action HUD to make all your Pokémon perform the chosen action.

Example: Squirtle, defend me! / Bulbasaur, want to eat some berries I dropped?

Primary Type-based Actions

These actions only work when the Pokémon has the right primary type.
Example: Charizard (fire, flying) can use cook, but Chandelure (ghost, fire) cannot.

• Cook (Fire): Can cook food and smelt ores. 5% chance of item turning into charcoal.
• Grow (Plant): Grows tree saplings and crops.
• Repair (Metal): Repairs tools and weapons up to a durability threshold.
• Shift (Ghost): Teleports the player between dimensions with temporary buffs and debuffs.

General Actions

These actions work with any pokemon!

• Attack: Pokémon attacks nearby mobs.
• Protect: Targets hostile mobs near the player; otherwise follows the player.
• Eat: Consumes edible items dropped on the ground (some foods and berries grant effects).
• Buff: Grants the player a positive status effect based on type.
• Debuff: Applies negative status effects to nearby mobs based on type.
• Sit: Pokémon stays in place.
• Idle: Cancels commands and returns to normal behavior.

Configuration

CobbleBrain is highly customizable and can be configured entirely in-game.

Press Y to open the configuration menu, where you can customize AI behavior, dialogue systems, gameplay mechanics, memories, actions, quests, and more.

Recommended settings for new players:

Selected Language — Changes the language used by the AI during conversations.
Instruct — Defines how the AI should behave and respond. You can customize it to make Pokémon more serious, funny, emotional, roleplay-focused, or anything else you prefer.

All the settings include tooltips explaining what they do!
