How to create your own mythological creature
Give your creature a purpose.
Thinking about the purpose of your mythological creature can help you to shape the development and look of your beast. This is especially important if you are creating a creature as a part of a game.
Will your creature be a background part of a fantastical environment you want to create, a mount for a hero figure, or a fighter? Many mythological creatures have specific vocations or relationships to other creatures in a universe. Decide if you want your creature to be a companion to a creature that already exists.
