Sketch of the Leviathans

The Leviathan species or Aliens of the Another World and massive, highly intelligent and curious yet deadly creatures and apex predators of the other world. The forms of the Leviathans depend on environment and other factors as they can have may forms with some better suit for sea, air or even jungles to mountains, though they do seem to have some similar to each other but this is more of the needs more then anything, They seems to be primary reptile like of all other animal types, they always have 2 hands and arms in some way shape or form, its easy to tell what is male and female, and finally don't be surprised by bizarre or weird forms like a Slime-Like or Full Fur cover one with scales under it. Its also confirmed they do have technology but have not full used it yet.

Besides being Apex Predators to almost all life on the world and have been seen destroying Major-Class Drones in MK0 Test and Several MK1 Criminals and Hunters, they are calm and even gentle giants as some seem not to harm families or child of the MK1 Test as well they only hunt what they need as they are more of an omnivore then carnivore.
