Petropia is a craggy, geode-like planet, and the homeworld of the Petrosapiens[1] and Crystalsapiens.[2]


Petropia is a jagged crystal mass.[merch 1] The Petrosapiens built a complex society of underground kingdoms and cities.[merch 2][merch 1]

After several centuries of intra-planetary warfare, a giant hole was ripped in the sky, revealing a universe far beyond Petropia's heretofore self-contained existence.[merch 2]


Specialized Petropian crystals can be used in the creation of hard-light technology, which was present in Tetrax's X321 Hoverboard.[pop-up 1][3]



Petropia was destroyed by Vilgax using energy from the Petropia Back-up Crystal, which was sold to him by a young Tetrax Shard.

Prior to The Secret of Chromastone, Tetrax, while exploring the ruins of the planet, learned what the true nature of the crystal was. He then stole it back from Vilgax and gave it to Sugilite. It was used to restore Petropia and its people by Ben (as Diamondhead). The crystal was returned to its home and given to its guardian, Sugilite when he was also revived, where it will be protected. Petropia is guarded by Sugilite.
