Petrosapien

Petrosapiens are a race of crystalline humanoids from the planet Petropia.

Anatomy
Petrosapiens are silicon-based lifeforms slightly taller than Humans with skin made from a diamond-like material. They have four-fingered hands, and toeless feet. Male Petrosapiens have a spike on the back of their head and two to six additional ones on their back, while females do not.

There are many different races of Petrosapiens. One notable race is the Surface Petrosapiens, who are lean and thin with square bodies and limbs. Their sharp edges are chiselled like carefully crafted sculptures.

Another known race of Petrosapien is the Subsapiens, who are much larger and have wide bodies with thick limbs, with some having crystalline growths on their foreheads resembling pompadours.

Although their crystal skin is traditionally blueish-green, Petrosapiens can come in other gem-like colors and shapes depending on their race. For example, Crystalfist has purple skin and Negative Diamondhead has pale purple skin.

Powers and abilities
While jewel-like in appearance, Petrosapiens have crystalline bodies that make them incredibly resistant to most physical attacks, such as a Piscciss Volann's bite. For Omni-Enhanced and Omni-Kix Petrosapiens, their natural durability is increased thanks to their respective armors.

Petrosapiens are able to shoot crystalline shards at rapid speed and alter their bodies into crude tools, including blades that cut through most materials.

Petrosapiens can manifest large, almost mountainous formations from either their projectiles, walls, or the ground itself and manipulate them under their control to the point of making them explode or levitate. They can even generate and retract these formations, such as giant spikes, from their own bodies.

Petrosapiens possess superhuman levels of strength due to the nature of their bodies, enough to make their shredding appendages especially devastating.

Petrosapiens can regenerate their injuries to a certain extant and extend their arms to superhuman lengths.

Similar to Crystalsapiens, Petrosapiens can survive in the vacuum of space.

Being living prisms, Petrosapiens can deflect and absorb most energy attacks, allowing them to render light and beam-based weaponry useless by simply refracting them. They can primarily absorb light waves such as lasers.

Since Petrosapiens are made out of organic crystals, they are impervious to a variety of elements such as fire, electricity, and magic. Therefore, they are unaffected by the attacks of species such as Pyronites or Weatherheads.

Being diamond-like, Petropsapiens are incapable of aging. Therefore, they cannot be affected by the time rays of a Chronosapien or a Chronian because diamonds do not age.

Correlating with their pyro immunity, Petrosapiens can absorb solar heat, preventing them from developing hallucinations when in an extremely hot environment.

Petrosapiens possess enhanced dexterity, being able to make additional fingers appear on their hands.

Due to the alterations Kevin Levin has made to the Antitrix, Crystalfist is more powerful than ordinary Petrosapiens. He can also shape any crystals he generates into anything he desires, such as tentacles.

Omni-Enhanced Petrosapiens can channel and convert absorbed energy into weapons formed from their arms.

Similar to Fulmini, Omni-Enhanced Petrosapiens can shoot Omni-Enhanced energy out of their arms.

Omni-Kix Petrosapiens can teleport their consciousness through their crystals, allowing them to use their regular body as decoys for opponents. They can also equip katar-like blades on each of their forearms that double as shields.

When under the effects of an Earth cold, Petrosapiens can accidentally sneeze out tiny crystal shards from their mouths.

Weaknesses
Petrosapiens are particularly vulnerable to sonic vibrations. While a stereo blast might cause them to splinter, certain ultra-high-pitched sound waves can cause them to shatter, including a Loboan's sonic howls, an Antrosapien's sonic wails, and an Evolved Sonorosian's Sonic Disks.

The shards on a Petrosapien's back can leave them stuck to a wall or on other surfaces that they get knocked into; this weakness only applies to males because females do no have shards on their backs.

Since their bodies are made of diamond, Petrosapiens can sink in water.

Petrosapiens can be lifted by a species with as much strength as a Tetramand.

Petrosapiens cannot walk on slippery surfaces, such as ice generated by a Polar Manzardill.

Despite being fireproof, a Petrosapien's shard projectiles can be dissolved by an Evolved Methanosian's fire attacks.

Petrosapiens can be blinded by a Lepidopterran's slime.

Petrosapiens can be easily overpowered by a Celestialsapien's telekinesis.

There is a clear limit in how much damage a Petrosapien's body can take before cracking or shattering. Once they break completely, no glue in this galaxy or the next can put a Petrosapien back together again.

Culture and society
The Surface Petrosapiens have built an advanced space-faring civilization. The Subsapiens, meanwhile, fight in violent wars for territory, unaware that they are being manipulated by the Antrosapiens.

History
The Petrosapien race originally dwelled beneath Petropia's crystal surface in underground cities. 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.

Due to the infighting between the various races on Petropia, they made it easy for the Chimera Sui Generis known as Vilgax to manipulate them long enough to destroy Petropia using energy from the Petropia Back-up Crystal, which was sold to him by a young Tetrax Shard.

Years after Petropia's destruction, Tetrax learned from exploring the planet's remains what the true nature of the Back-up Crystal was. After stealing the crystal back from Vilgax, Tetraxx made his way to Earth and gave it to Sugilite, the Crystalsapien guardian of Petropia. Arriving to Petropia, Sugilite used his powers to restore the planet itself before being nearly killed by Vilgax.

Using both the Back-up Crystal and his Petrosapien form Diamondhead, Ben Tennyson was able to finish Sugilite's mission and revived the Petrosapiens. As gratitude for saving his life, Sugilite allowed the Omnitrix to sample his DNA, restoring the destroyed transformation Chromastone.

Alternate history
In Dimension 27998.3, Petropia was never destroyed by Vilgax because he never arrived on the planet to begin with. As such, Petropia remains intact and the Petrosapiens are thriving.

Long ago, the Surface Petrosapiens split from their Subsapien ancestors and relocated to the surface. Meanwhile, the Subsapiens remained underground in the deep substrata of Petropia. After the two factions became exhausted by their endless civil war, the Antrosapiens launched a surprise sonic attack. The Subsapiens begrudgingly allied themselves with their surface cousins to survive the greatest threat to their species. They constructed a war machine capable of absorbing the Antrosapiens' sonic attacks and redirecting them as a powerful energy blast, successfully dealing a devastating blow to the Antrosapiens.

Petropia would later become under siege by a Fulmini invasion party, leading to the Surface Petrosapiens, the Subsapiens, and the Antrosapiens to join forces and protect their planet. The Fulmini were quickly driven off, and all three factions were finally at peace. Wanting to take a break after their war against the Fulmini, the Petrosapiens went to Appoplexia and used crystal constructs to keep the Appoplexians entertained.
