Petrosapian

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

Appearance
Petrosapiens are made of a green/blue 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. And Males are more bulky and muscular, while Females, while having some bulk, are a bit thinner.

History
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.

However Later due to the unwillingness of Tetrax, Petrosapia was destroyed and its now a barren wasteland.

Powers and ablities
Petrosapiens are highly resistant to most physical attacks and are physically enhanced due to their crystalline bodies.

Petrosapiens are able to alter their bodies into crude tools, such as blades, as they can generate crystalline substance on their bodies, which can allow them to regenerate unless they break completely.

Petrosapiens are able to shoot crystalline shards at rapid speed, generate blades that cut through most materials, and causing large, almost mountainous formations under their control, to manifest and spike out, either from their projectiles or from walls and the ground itself, as well as other structures. They can even generate these formations, such as giant spikes, from their own bodies, as well as retract them.

Being living prisms, Petrosapiens can refract, absorb and redirect light and energy beam, channeling them through their bodies and projecting them back at their source.

Diamondhead has been shown to mimic earthbending to manipulate the crystals he creates

Weakness
Neither Petrosapiens nor their crystalline constructs are invulnerable and can crack and break like glass if they are exposed sonic vibrations or are impacted with enough force.

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.
