Leviathans are massive aquatic predators found in large bodies of water in Shoreline, Subterranean, and Submerged Superstructure. They are the largest predators in the game, capable of hunting and eating any other creatures in the water.

Appearance

The Leviathan appears to be biomechanical, having an organic body and a hydraulic mouth at the front. This mouth consists of metal rods that move the jaws and large grooves that allow them to clamp down onto prey.

Their body consists of progressively thinner segments that end in a long tail, with large fins and smaller frills of varying lengths along their sides. The former are generally longest at the front of the body, while the latter tend to be longest toward the middle of the body. A gradient runs across most of the body in a marbled pattern, ending near the tail. Their head displays patches of color from the same palette.

Tips

Combat & Stealth

Leviathans cannot be practically killed in normal play due to their large health pool. Avoiding detection is also difficult due to their large size.

Evasion

Leviathans can outpace a swimming Slugcat, making outmaneuvering them near-impossible in open waters without aid or knowledge of swimming techniques. If possible, it is best to avoid large pools altogether, or wait until they have eaten enough food to become dormant for the rest of the cycle. If passing by one is necessary, the safest way to do so is by getting hold of a Jetfish, as they are fast enough to swim past Leviathans safely.

Abilities & Behavior

Leviathans have extremely good, omnidirectional sight, somewhat limited by the surface of water but not by water itself, making them able to near-perfectly see the creatures around them. After noticing potential prey, a Leviathan moves towards it, extending their jaws out when close enough, and clamping down on it, consuming whatever is caught in their jaws. Leviathans only hunt in a room for a certain amount of time, effectively turning passive and leaving after that amount is reached.

A variety of possible Leviathan colorations

Albino

A unique albino Leviathan can be found in the lake on the eastern side of Subterranean, featuring a white body with pink markings. In Arena, any Leviathan has a 4% chance to be albino.^{[v1.9 Remix only]}

A golden Leviathan variant found in Rubicon has a brown body with markings that fade from white to gold. They are immune to Void Fluid, though it slows their swimming speed.

Trivia

• The Leviathan can eat any creature that gets stuck in their mouth, no matter how large, because any body segment caught in their jaws destroys the whole creature.
  • This would even include other Leviathans, but there is a line of code preventing this from happening.
• The development of Leviathans as documented in the dev log.
  • Leviathans are stated 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 far beyond what players are practically 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), though there is no practical reason to do so, as killed Leviathans naturally respawn in a few cycles.

• • Large quantities of shocks delivered by an Aquapede underwater can kill the Leviathan.
• Leviathans, despite being very large, can be eaten by Monster Kelp, 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 Squidcadas.

SPOILER WARNING: Ending
This section contains major plot details from the end of the game. If you have not yet completed the game on any difficulty, then read no further!

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