Pokemon Card AI Generator

This is a Python script that uses AI to generate new, random Pokemon cards. It picks from 6 elements and a type of creature, and random generates 1-2 abilities.

It then uses OpenAI to generate a Pokemon name and a description, and creates a prompt for Midjourney (which needs to be used manually).

Then a separate command can be used to combine the Pokemon data with the generated artwork to create a new Pokemon card.

Final Results

Card With Details

The finished generated card will have a name, description, and card artwork.

Description	Card Image
Ignax is a sweltering hot Pokemon found in desert-like regions that brandishes a deadly dark axe. It is known for its fierce demeanor and its Ignition Surge ability, which it uses toits advantage in fierce, awe-inspiring battles.

Series Of Cards (Evolution)

The script can also generate a series of cards that evolve from one another.

Form 1	Form 2	Form 3

For the full example collection, see the gallery.

Metadata

The output will be in the /output folder, with empty folders for you to put card artwork into.

[project root]
├───output
    ├───cards
    ├───images

The cards will have JSON like this:

{
  "index": 26,
  "name": "Flamo",
  "description": "...",
  "element": "Fire",
  "rarity": "common",
  "rarity_index": 0,
  "hp": 50,
  "abilities": [
    {
      "name": "Scorch",
      "element": "Fire",
      "cost": 2,
      "is_mixed_element": false,
      "power": 40
    }
  ],
  "image_prompt": "a chibi young fire-type parrot pokemon, in a volcano environment, lava texture background, anime chibi drawing style, pastel background --niji --ar 3:2",
  "image_file": "026_flamo.png"
}

You can use the image_prompt to generate the card artwork with Midjourney.

Setup

1. Install Python 3.10 (or higher)

2. Install the dependencies with pip install -r requirements.txt

3. Set your PYTHONPATH to the src so that the modules can be imported.

   # For bash, you can use:
   export PYTHONPATH=$PYTHONPATH:src

OpenAI and Midjourney

If you want to use OpenAI to generate names and descriptions, you will need to set up an account with OpenAI.

Then put your API key into a file called .env in the root of the project.

# In your .env file
OPENAI_API_KEY="sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

If you want AI generated artwork, you will also need to set up an account (just join their Discord) with Midjourney.

Usage

Running this will generate a collection of Pokemon to the output folder. WARNING! Each time you run this, it will overwrite the existing files in the output folder.

Generate Cards (1 Series Per Element)

python src/generate.py

This will generate card json files, 1 card series (between 1-3 cards) for each element. The rarity, creature type, and number of evolutions of the cards will be random.

You will see the summary of the card series generated:

Chippo (Neutral)
HP: 30
Rarity: ★  (common)
Abilities:
  Slash (Neutral)
  Cost: ● ●
  Power: 20

Description: [...]
Image Prompt: [...]

Generate Cards (10 Series Per Element)

python src/generate.py -n 10

Generate Cards of a Specific Element

python src/generate.py -e fire

This will only generate cards for the fire element. Available elements are: fire, water, grass, electric, psychic, neutral.

Generate Cards of a Specific Creature Type

You can also specify a specific creature type (subject) to generate cards for. This will override the default subject selection (which is random).

python src/generate.py -e grass --subject pumpkin

You can literally put anything here! Have fun with it 😄

Pumkpin	Toucan	Sphinx

Use Midjourney to Generate Card Artwork

You can use the image_prompt to generate the card artwork with Midjourney. The image prompt will be in the json file for each card (and also in the image_prompts.txt in the output folder).

Chippo::0 a chibi young neutral-type toucan pokemon, in a village environment, bright lighting, anime chibi drawing style, pastel background --niji --ar 3:2

Copy this into the Midjourney /image prompt. It will generate 4 variations of the image. You can then upscale it by pressing one of the U buttons on the bot.

Download and save the image into the output/pokemon-classic/images folder. Then rename the file to match the image_file in the json file (e.g. 001_chippo.png).

Render the Cards

You can use the render_cards.py script to render the cards into a PNG file. It will go into your output/pokemon-classic/renders folder.

python src/render_cards.py

Any cards that have an image file in the output/pokemon-classic/images folder will be rendered. If no image is found, it will render a blank card.

Available Elements

fire	water	grass	electric	psychic	fighting	neutral
