Lavos

Lavos and Lavospawn are bioorganic organisms which are dropped onto planets from an unknown home source, only to enter hibernation for many millions of years before finally draining the planet of all its energy. After destroying the planet's surface, it will spawn a multitude of clones (the Lavospawn) and prepare them to infect other worlds. If awakened prematurely, it will often defend itself against its intruders and has the power to transport them through time or simply eradicate them in an instant.

History
The organism called Lavos arrived on the planet in the year 60,000,000 BC, at the close of a war between Reptites and cavemen. Obliterating the reptite stronghold, the creature immediately began to burrow into the planet core. During the Ice Age of 12,000 BC, the creature's great energy was harvested by the Zeal Empire. When the energy extracting equipment was moved to a place on the surface closest to Lavos, the creature awoke and scattered the Zeal royal family to the winds of time. The young prince Janus was transported to the middle ages in the kingdom of Guardia, where his great skill in magic allowed him to make progress as a wizard. Studying Summoning magic, he attempted to summon Lavos to kill it in revenge for his sister Schala's presumed death at its "hands". However, his summoning ritual was disrupted by the appearance of the warrior Glenn, whom he had turned into a giant frog ten years prior, and a band of sorcerers. Lavos continued to sleep until the year 1999 AD, where it proceeded to lay waste to the planet's surface. Moving to a mountain called Death Peak, quite possibly the world's tallest, it began to spawn clones to infect other worlds. However, due to a time-travel quest by the aforementioned Glenn's companions, including the princess of Guardia, a mad scientist, a peasant boy, a re-programmed security droid, and the Ioka chieftan, (and possibly Janus himself), Lavos was killed when it finally surfaced.

Terminology
The name Lavos is an Ioka word, "La" meaning "big", and "Vos", meaning "fire"

Overview
Lavos has an outer shell that resembles a cross between an ant and a sea urchin. This shell is incredibly tough, and considerable force must be used to crack it open. The shell is capable of projecting plasma beams, and can store enough energy to cause a nuclear winter. Inside the shell is a cave-like structure that emits faint green light. At the core, there is a creature resembling an astronaut at a desk, which presumably is spawned along with the rest of the body and lives its entire life within the outer shell; this is the true Lavos. Despite its visage, it is incredibly potent in combat.

Lavos burrows into the core of a world once it lands on it. It continues to absorb the planet's energy and direct evolution to the point where the inhabitants can create massive power plants, such as nuclear reactors. With this jump-start, it kills all or most of the inhabitants by making the world uninhabitable. It then moves to a point on the surface closest to space, and churns out babies, much like a female rabbit or gerbil (only asexually). These young lavos can move through space without any mechanical assistance; although the species appears to already be biomechanical by nature. Lavos is reffered to with male pronouns, but it has more female traits.
