How to design creatures for your fantasy or scifi world

Table of Contents

Dragons, revenant astronauts, talking trees… fresh creatures turn a setting into a place readers want to live (or run from). Fantasy and sci-fi worlds can be really creative, and the ability for you to invent anything you want within them is what makes them so much fun to design. So, I’ve compiled a few foundational questions that you can use to help you design creatures for your fantasy or sci-fi world.

1. What Narrative Job Does the Creature Perform?

Before you go ahead and add a creature, try to think about what the point of this creature is in your story. Here are some examples you can think about, but don’t feel restricted to these choices:

RoleStory Payoff
Predator obstacleRaises tension during travel scenes
Ally / mountSpeeds up quests, showcases culture
Sentient rivalMirrors or mocks your main society

Key takeaway: When adding a creature to your story, make sure the purpose is clear to the narrative.

2. How Does the Environment Shape the Creature?

Depending on the environment that you live in, you likely can step outside to see certain animals but you won’t see others. For instance, scorpions are common in the desert but you’re probably not going to find one in the middle of Ohio. I would know, I grew up there LOL.

Something that I made sure to talk about in The Ultimate Guide to World Building is the idea of how the environment and the biome that you’ve selected shapes the geography, the society, and even the creatures of your world. I also give you guiding questions on how to apply all these things together.

Key takeaway: Think about how your environment impacts the creature and the way it looks/acts.

3. What Makes Them Memorable?

When it comes to your creatures, you need to think about what makes them memorable to your readers. For instance, there’s a trait that they happen to have that makes them feel different compared to the standard way people live. Maybe they use magical echolocation or they have some sort of ritual.

When it comes to creating creatures, depending on their role in your story, their complexity can differ. The more of a role, the more you want to try and make them memorable.

Key takeaway: Make sure your creatures have something your readers can remember about them.

Three Common Missteps

  1. Environmental mismatch: A creature that exists in the snow is probably not made for a volcanic area
