A juvenile Gravios, Basarios has not yet developed some of its trademark features. Although its shell is very tough, it is not nearly as strong as an adult's. In the Val Habar region, there is a subspecies that is covered with beautiful pink crystals.
They are far weaker than Gravios, so they rely mostly on their camouflage and hard outer shell to deter attacks. Basarios are abandoned by their mothers shortly after being born, and spend much of their early lives feeding and looking out for themselves. Large predators, such as Akantor, will try to prey on the juvenile wyverns. Basarios must rely on their camouflage as their main defense. While ores and minerals are a large part of their diet, they will feed on Herbivores and Neopterons in order to gain protein by ambushing them from the ground.
Thick, rock-like shells protect Basarios from most of the volcanic heat. Basarios has relatively large claws on its short wings, used to assist the creature in digging. Basarios's short tail has not yet developed into Gravios's trademark mace-like appendage. A Basarios's back resembles a rocky outcropping commonly found in the volcanic region and serves as a crude yet effective camouflage. When all else fails, Basarios can expel either a burning, poisonous, or sleep-inducing gas from pores all over their body. The gases are the remains from its previous meals.
Some rare individuals develop very strong poison and flame sacs and are known for extreme aggression to the point of pouncing or rolling on their attackers, smashing them instantly. They appear to be stained by poison around the pores on their body and have unusual blue eyes. It is unknown if they are a mutation or simply have unique behaviors.
Much less aggressive than its adult form Gravios, Basarios are content with maintaining their rock-like camouflage and feeding on minerals. Basarios can become aggressive when attacked, spitting fire balls, firing heat beams and ramming their opponents when threatened.
