Leviathan

Leviathans are hostile aquatic creatures found in large bodies of water in Shoreline and Subterranean. They are the largest predators in the game, serving as a fearsome threat to and any other creatures that get too close to the water.

Appearance
Leviathans seem to be biomechanical, having a primarily organic body and a hydraulic mouth at the front. Their mouths consist of metal rods, and jaws with grooves that allow them to clamp down onto prey. Their bodies are made up of progressively thinner segments that end in a long tail, featuring large fins and smaller frills of varying lengths, with the former generally being the longest at the start of the body, while the latter tends to be the longest towards the middle of the body. A gradient runs throughout most of the body in a marbled pattern, stopping at the tail when it becomes too thin. Their heads also feature some bits of color from the same palette.

Evasion
Leviathans can outpace a swimming on their own, and outmaneuvering them is near-impossible in open waters without aid or good mastery of swimming techniques. If possible, it is best to avoid large pools all together, or wait until they have eaten enough food to become dormant for the rest of the cycle. If passing by one is necessary, the easiest way to do so is by getting hold of a, as they are fast enough to swim past Leviathans safely.

Abilities & Behavior
Leviathans seem to be able to near-perfectly sense the creatures around them, not relying on sight or sound. After sensing potential prey, a Leviathan moves towards it, extending its jaws out when close enough, and clamping down on it, consuming whatever is caught by its jaws. Leviathans only eat a certain amount of food in a cycle, effectively turning passive after that amount is reached.

Variants & Attributes
The gradient found across a Leviathan's body can take on a variety of colors, from deep blue, through cyan, green, and even magenta or purple. A unique albino variant of the Leviathan can be found in Subterranean, featuring a white body with red accents.

Trivia

 * Leviathans can eat any creature that gets stuck in its mouth, no matter how large, because any body segment caught in its jaws will delete the whole creature. This would include even other Leviathans, but there is a line of code preventing that from happening.
 * Leviathans are stated in the devlog on Tigsource to be designed to invoke the fear of having a piece of seaweed touching your feet in the ocean.
 * Although Leviathans can be killed, their resistance is beyond what players will typically be able to overcome in a single cycle, making them nearly immortal. A persistent player may be able to kill a Leviathan with an incredibly large stockpile of explosives (or with the help of modding), but doing so is obviously not recommended, as it would take an entire cycle and only prevent the Leviathan from appearing until it naturally respawns a few cycles later.
 * The Leviathan in Subterranean being albino may be in reference to the albinism documented in cave-dwelling fish, who develop it in an extreme lack of sunlight.
 * Leviathans, despite being very large, can be eaten by, though it is unlikely the two creatures would come close enough to each other outside of arena mode.
 * The metal plate asset on the front of the Leviathan is reused in-game on the upper bodies of.
 * The albino leviathans marbling is red, like an albinos eyes would be. This implies that the marbling functions as the eyes of a leviathan.


 * Leviathans, especially the albino one, share physical traits with - a similarity which has been confirmed by the developers not to be a coincidence.
