The planet was destroyed by Vilgax with assistance from Tetrax, who unknowingly helped him create the weapon that destroyed his home. Petrosapiens bodies is composed of an extremely durable organic crystal, making them nearly invulnerable. Petrosapiens can control their crystal physiology at will, allowing them to create crude crystal weapons from any part their body on demand or fire crystal shards from their hands. This same ability also allows them to regenerate to an extent, such as regrowing lost limbs. In addition to growing crystal from themselves, Petrosapiens can grow crystal over other objects. Lasers and other similar weapons are useless against Petrosapiens, as their crystal bodies acts as a prism, refracting the beams. The one drawback to Petrosapiens crystal form is the crystal itself, which can shatter if exposed to sufficiently strong sonic vibrations. While Petrosapiens can regenerate limbs, there is a limit to how much damage they can recover from.
