The Ghost Leviathan is a 107 meter long leviathsn class organism that is found around both the crater's edge and the Lost River of 4546B. The lost river ghost leviathsns are actualle juvenile, and are about the size of a Reaper Leviathan, or a Cyclops class Submarine. The Ghost leviathans actually have eggs, that can only be seen growing pn the Giant Cove Tree, as the eggs were laid when the tree was young, and the eggs are so old that the tree grew vary large around these egs. The ghost leviathan has a large hammer head in order to do heavy hitting ram attacks on its prey or its hiding spots, revealing them. It swims in a strange circular motion, alowing it to be really fast. It will eat ghost rays, river prowlers, and other small creatures in the lost river to grow, however, when thwy are fully grown, they move to the crater edge and feed off of microorganisms. They only attack there due to the edge being their territory.

The Shadow Leviathan is a 60+ meter long Leviathan Class organism that can be found exclusively in large caves of Sector Zero of 4546B. It has a large triangular head with 3 eyes on each side, and a mouth lies underneath the head, which is bioluminescent and blue. The mouth is long, and also has many long, blue teeth. The shadow leviathan is a very oppritunistic hunter, going for any large prey, presumably because of the lack of any of large animals in the Crystal Caves and Fabricator Caverns. The few animals even there are small fish and bacteria, which is hupothesized to also feed the shadow leviathan's massive appetite. It is capable of nearly destroying a seatruck or prawn suit before letting go of you with its large mantis-like arms. It has a long eel-like body to easily move around large crystal formations.

The Chelicerate is a leviathan class organism that lives in moderate depths of Sector Zero of 4546B. The creature will patrol around the area it is in for prey, which can be anything from small fish to brute sharks. Once the chelicerate finds its prey, it will screech to disorient, or in some cases, stun its prey. Then, it will eat its prey with its large chelicerae, which can crush bomes and rip muscles apart. The chelicerate is an aggressive hunter, and will attack you and any vehicle you are in at the moment.

The Reaper Levoathan is a 55 meter long apex predator with an insaciable hunger. This leviathan class organism has very thick muscles and a small brain, and large mandibles to grab both smaller prey and larger prey. This menu for the reaper leviathan includes you, and your many vehicles you would drive. They can often be found in barren areas of The Crater of 4546B. The reaper has an exholocation ability in which it roars from far away, and if you can hear the roars, it has found you. The streamlined body of the creature along with its high muscle mass makes it very fast and manuverable.

The Crabsquid is a species of large creature that lives in deeper areas of The Crater of 4546B. Crabsquids are large predatory creatures which are not as large as leviathan class organisma, but they are pushing the size limit for creatures who are not. Crabsquids often swim around or walk on their legs on the seafloor until spotting large prey, where they start to swim near and release large EMP waves to disorient prey so it can eat it. They make clicking noises to help echolocate their prey in the darkness.

 The Reefback leviathan, or just the Reefback, is a large leviathan class organism which is very strange in its biology, having evolved drastically to survive attacks from now extinct predators. Often, the reefbacks can become centuries old, and have many species of coral and plants grow on its back, putting their roots into deep scars in the large chitonous back. The creature evolved this back, asbits just one chitonous large bone like structure, as opposed to the other evolutionary paths of a spine with multiple vertibrae. The Reefback has large fina that look like claws, but actually control where the creature turns. The reefback will produce booming calls and songs like earth whales, using 2 large mouths on its sides, which also filter microorganisms from the water. The bottom also has blue bioluminescent stripes, and a collection of enzyme pods, which have no real purpose. Often, resources can be found on its back.

U.M.F. leviathan

**“Iron Leviathan”** is the common name for *Colossus ferrovitae*, a next‑generation armored platform developed during the era of autonomous battlefield engineering. Its dense, weathered plating wasn’t just protection, it housed a layered bio‑reactive alloy that subtly shifted rigidity under stress, a breakthrough meant to reduce catastrophic hull fractures. The clustered optics atop its turret formed an early multispectral array capable of reading thermal gradients across kilometers.

Its unexpected purpose emerged during environmental recovery missions. The Iron Leviathan’s immense stability and sensor suite made it ideal for navigating toxic, debris‑laden zones where human crews couldn’t operate. Over time, *C. ferrovitae* became less a symbol of war and more a rugged sentinel of restoration, proving that even the heaviest machines can be repurposed toward renewal.

A large-scale abyssal whale creature sculpted in ZBrush.

Designed as a deep sea leviathan, this model also works at smaller scales easily transforming into an alien fish-like creature depending on use.

This flexibility makes it suitable for a variety of applications, including games, cinematics, and creature design studies.

Features:
High-detail organic sculpt
Strong silhouette for large-scale creatures
Scalable design (Leviathan → Alien creature)
