Lifeform Maker - System-Neutral Alien Species & Creature Generator for Sci-Fi RPGs

Already have a creature that needs a different look or a few unusual traits? Or do you need to invent a species from the ground up? This system-neutral toolkit supports both, with a quick modification method and a more detailed set of alien-creation tables.

"Our sun is one of 100 billion stars in our galaxy. Our galaxy is one of the billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living things in that enormous immensity."
— Wernher von Braun

Start with a creature, or build a species

The quick system changes an existing creature without asking you to begin again. The detailed method builds a new base species, and example creations demonstrate both approaches.

Eight baseline templates offer starting points: Aquatic Animal, Avian, Insect, Invertebrate, Mammal, Plant/Fungi, Reptilian and Rock-Based. From there, the tables let you work through more than appearance alone:

• Physical form: Size, height and length, weight, shape, limbs, colouration, skin and hide, and strength.
• Life and behavior: Age and lifespan, communication, diet, intelligence, movement, pain tolerance, reproduction, senses, and sleep or activity periods.
• Environment: Terrain and temperature tolerance, with Advantages, Disadvantages and Quirks tables adding further biological and behavioral detail.

The output is a creature’s biological form and natural abilities rather than a game-specific statblock. That keeps the generator usable across sci-fi, modern and future-setting RPGs, while leaving the rules translation to your game.

Society and technology are outside this volume’s scope. The publisher describes those subjects as material for a separate companion publication designed to work with this one.
