Petrosapiens are a species of silicon-based lifeforms from the planet Petropia.

Petrosapiens are made of a green diamond-like material. They are a little taller than humans. They have four digits on their hands and none on their feet.

Male Petrosapiens have a spike on the back of their semi-cubic head and two to six on their back; females don't.


The Petrosapien race originally dwelled beneath Petropia's surface. After several centuries of warfare, a giant hole was accidentally ripped in the surface of Petropia, revealing a universe far beyond Petropia's heretofore self-contained existence.

With the inadvertent discovery of space, Petrosapiens began to stabilize their civilization and they began to explore the surface of Petropia and the rest of the universe.

Powers and Abilities

Petrosapiens are virtually invulnerable to most physical attacks.

Petrosapiens can regenerate to an extent.

Petrosapiens are able to alter their bodies into crude tools, such as blades.

Petrosapiens have other diamond-based powers: shooting diamond shards, being able to cut through most materials, and causing large, almost mountainous formations of diamond.

Being living prisms, Petrosapiens can refract light and beam-based weaponry, channeling them through their bodies and projecting them back at their source.


Petrosapiens are vulnerable to sonic vibrations. While a stereo blast might cause them to splinter, certain ultra-high-pitched sound waves can cause them to completely shatter and might even fall unconscious.

The two shards on their back can leave Petrosapiens stuck to a wall or on other surfaces that they get knocked into.

    • No. Sapien means intelligent being and predators are usually unintelligent.
    • Ditto to the comment above.
