After looking over a few pictures I did, Another Worlds, Space Stations and few others based on the idea, I always did these creatures or species (Sometimes on Purpose XP) So I decided to make them a Species

They are Called Leviathans
(Note: Do to a lot of misclick and errors to the Pictures as a Sketch and the Information been deleted and had to be redone @.@)

What Are Leviathans:

They are large reptilian creatures that live on the planet Terra (Which is Bigger Form of Earth with a Ring created by one of 2 moons from being impacted) located opposite of the Solar System in the Milky Way, they are both highly intelligent and adaptive lifeforms having survived an Extinct Level Event and remaining the top Apex Predators of there planet with almost no changes to there genetic and DNA for the last thousand centuries. There are not know for being a War Like Races but they are not strangers to war and major conflicts when it happens

Common Features of Leviathans though all there forms/species: Single Head, Pair Arms, Male & Female Chest to Low Body, and Tail

Who where they Encounter:

Its Unclear how humans encounter the Leviathan species, some theories say it was from Wrap Experiments, Space Station Research, Space Exploring, or possible Leviathans encounter use first. But all have the same result in the end, Do to how armed humans are, several ships that can be design for combat and even major amounts of humans "Hate Xenos" Made the Leviathans Question humans about there actions.

Though some humans are seen as good and even let to come to there world to live with the Leviathans, Leviathans are always on guard and at points VERY untrusting of humans do to actions they do at the time. This had lead to one conflict which the humans learn a very important lesson lucky for humans it was not full on war with Leviathans as there was not way they could win

Technology and Conflict:

Leviathans are see using a large range of advanced energy weapons, gear and vehicles with a mix of Robotics and Ecologist tech, both for war and civilization, its no surprised Humans loses the first conflict with them.

The Conflict start from a misfire against one of the Leviathan ships which was causes by a Civil War between 2 human groups. Needless to say the Civil War had Ended within 2 mouths by Leviathans and Humans now need to be more careful about it next time, though some say those humans groups would want revenge against the Leviathans though how will they do is unknown..
