Aliens (Planet Monsters)

These Aliens are a collection of related, unnamed life forms. Very little is known about these aliens as all of them are currently extinct, and forgotten about outside of the fossils uncovered.

Species
While there seems to be numerous subspecies to this Alien species, much of their anatomy is the same in terms of size: most, if not all, of the Aliens are Kaiju-sized; their carcasses molding landscapes into hills and mountains with craters surrounding where they fell. Currently there're four known subspecies of this alien race:

"Hexapod Alien"
This Alien is nickname'd due to the numerous sets of legs it has: two sets of legs in the front, three in the back, and a single longer pair along its sides. This Alien has tentacle-like appendages along its back. Despite being colossal, they are frail-looking as much of their actual body (comparatively speaking) is quite thin. Fossils of this alien are fairly common to locate, as several are found in isolated pockets on their planet.

"Tortoise Alien"
As the nickname implies, this Alien strongly resembles a giant Tortoise: two sets of very thick and stocky legs and a large back. However, despite appearances, its back is made entirely of crackled skin, and not made into an actual shell. Its head as well doesn't hold any recognizable facial features, ending only in jagged spikes with a large horn at the tip.

"Leviathan Alien"
This Alien is fully aquatic, though it's the only Alien to not have a specific size measurement, as vague of an idea as the others are. It has a very sturdy body with no means of locomotion out of water: four sets of fleshy fins similar to a whale, with much of its body dragging behind it as it swims. Its mouth is filled with jagged teeth that jut out forward, and a few sets of sturdy "horns" jut out from the forehead.

"Dragon Alien"
This one in particular is the most well-known specimen of the Alien species, in part due to its resemblance to the mythical Chinese Dragons. It has an elongated reptilian body like a serpent, with two sets of reptilian legs, and tree-like horns that protrude from its crocodilian-like head. This particular alien fossil is eerily close to planet Earth: inside a crater found on the Moon.
