Species Generator - V3!

Last updated: Tuesday 30th September, 2025 ~ What's New?

Populate your worlds with these weird and wonderful creatures!

Familiar uses recogniseable animal traits, Unique uses random descriptive traits, Hybrid uses both.

Use Form to determine either the rough shape or how many limbs your creature has (or doesn't have). This option overrides the amount of legs a creature would normally have depending on its class! If you want a mammal with 0 legs or a fish-centaur abomination, you can do that.
"Legless" creatures can be assumed to be either like a snake/worm or Lamia/Naga as a starting point.

Class determines what traits creatures have; Avians have feathers and beaks, Fish have scales, etc. Not EVERY creature will stick rigidly to their class rules!
The No. of young is how much a creature CAN have during its breeding period, not how much it WILL have specifically. Feel free to increase or decrease this amount.
