Terravore

Terravores are a sapient shapeshifting planet-eating species from the Urma-Annexate. One Terravore, known as the Shepherd, took the form of a god-like being in an attempt to consume Earth.

Biology
Terravores are massive, shapeshifting beings. In their true form, they are semi-humanoid beings with red skin resembling exposed muscle tissue, with several spikes visible on their forearms. Their elongated heads have four beady eyes and what appears to be a mouth extending from their forehead to their lower semi-humanoid jaw, lined with sharp teeth and bearing a tube-like tongue. In addition, Terravores have several mandible-like appendages around their mouths, also lined with sharp teeth. Their shapeshifting abilities enable them to take on the form of a Human-like being, albeit at massive size. True to their name, Terravores consume planets, carving them up and eating them down to the core. They are capable of firing energy beams from their eyes, even while in another form, and are immortal. They are known to "fatten up" a planet's population over the course of a thousand years before consuming it, implying that they can go for that period of time without sustenance, and that their main source of sustenance is the planet's biosphere rather than its materials.

Culture and society
Little is known of Terravore society, other than the fact that they target planets to fatten up and consume. They are known to take on Human-like disguises, masquerading as celestial beings akin to the Abrahamic God, and trick the population of a planet into serving them by granting them various superpowers while also poisoning their minds with some form of gamma radiation, making the population more subservient and less intelligent. After a thousand years of "fattening up" a planet, they will proceed to consume the planet and all who reside on it. Terravores are known not to recognize the authority of the Green Lanterns. Due to their diets, Terravores participate in planet-trafficking, focusing on shrunken planets that are easy to collect within their spacecraft, and are known to claim that they "liberated" the worlds they purchase.

Technology
Terravores are known to use large spacecraft with spherical sections for holding shrunken planets, which are suspended in the air. While appearing almost opaque from the outside, and in a yellow color, the coverings of the spherical component are transparent from within, showing a clear view of space. Terravores are also known to use large spray cans on the planets they collect, which is presumably what poisons and enhances the population of said planets.
