Sea Emperor Leviathan

The Sea Emperor is a life form belonging to the fauna category. It is still under development and has yet to be added in the game.

The Sea Emperor is expected to be peaceful or defensive once it is fully implemented and also to have a role in the game's story.

Appearance
The Sea Emperor is colossal in size, having a stocky body entirely armoured and predominantly brown in color, with a few shades of green. Most of its body parts are adorned or tipped with bright cyan bioluminescent glows.

The creature's head shape is quite peculiar (see "Trivia" below for more), featuring two glowing green-tipped antennae on top of its snout and two large mandibles on each side of its rather small mouth. It seems to possess four binocular eyes.

The Sea Emperor 's rearside consists of seven long, yet slim tentacles ending with small tentacular clubs, with the largest being surrounded by the other smaller ones.

Unlike the Sea Dragon Leviathan, the Sea Emperor doesn't have true graspers. Instead, its forelimbs are two massive, paddle-like arms.

Trivia

 * The Sea Emperor's model can be found in the Entity Gallery:
 * It currently uses the AI of the Bone Shark and completely lacks animation. It can attack, inflicting 30 damage to the player's health.
 * Once fully implemented, the Sea Emperor will be upscaled to be larger than the Sea Dragon Leviathan, and probably becoming the largest life form in Subnautica.
 * Certain developmental notes refer to the Sea Emperor as the Emperor Leviathan.
 * A Sea Emperor is featured at the very end of the official Subnautica trailer.
 * The Sea Emperor closely shares many of its features to real life animals: a head shape slightly similar to that of many hammerhead sharks, and paddle-like arms, resembling those of the green sea turtles.
 * Trello notes refer to this creature residing in a cave and having something to do with an unimplemented story.Further notes also imply that this story is taking a development route similar to the Lost River in that elements for it will be released in waves, the first of which is a "prison" 1440 meters down, at the coordinates (200, -222).
