Rock Lord

The Rock Lords are a race of mineral, rock-like entities with an appetite for metal who hail from the planet Quartex in the Gargent Cluster. In the Malgus Cluster, they hail from the Quartex System.

Biology
Rock Lords are a mineral species, whom, as their name implies, are made up entirely of rocks. In their dormant states, they resemble asteroids. However, they can be awakened if disturbed by light. This results in them changing into a humanoid shape. Their main diet is metal, to which they eat anything made of metal, including robots such as Cybertronians.

History
Eons ago, in the Gargent Cluster, a a civilization of advanced organic Ro-Beings, who were native to the planet Quartex, became threatened by the stellar radiation generated from a nearby star. Their connection to nature and dislike of technology gave them an idea. This idea was a plan to turn every living being into living rocks by having them fused with rock at the very moment the radiation wave hit. The plan was imperfect, and nearly every Rock Lord had forgotten who they originally were. The Guardians first encountered the Rock Lords during a battle with the evil Renegades, and thus, many later battles between the Guardians and Renegades involved the Rock Lords. This culminated in the Combiner Wars, which involved a team-up between the Guardians and the heroic Rock Lords and the Renegades and the evil Rock Lords.

In the Malgus Cluster, a cluster of Rock Lords were awakened by Omega Supreme, to whom they swarmed around him. Moments later, Bumblebee had made his way outside, and was quickly devoured by the nearest Rock Lord. As the Rock Lord prepared to return to sleep, it was disturbed to find itself alone on Earth. As the Sun shone down on it, the Rock Lord went on to destroy everything in its path, only for Sari Sumdac to appear and shatter the Rock Lord into hundreds of pieces. The three smaller remaining Rock Lords that regenerated from the shattered body of the first Rock Lord didn't even stand a chance.
