The Sea Emperor is a life form belonging to the fauna category. It is still under development, and is only spawnable by using the Debug Console Commands.

Once fully implemented, the Sea Emperor will be passive or defensive, and will also be the biggest creature in the game.

The last Sea Emperor is being held captive by the Precursors, and is in the Primary Research Facility.

Appearance

The Sea Emperor is colossal in size, having a stocky body entirely armored and predominantly pale brown in color, with a few shades of green. Its tentacles are adorned with bright cyan bioluminescent spots.

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

The Sea Emperor's posterior consists of seven long, yet slim tentacles ending with large tentacular clubs, with the largest being in the center, 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.

Behavior

Despite its gargantuan size, the Sea Emperors diet consists solely of micro-organisms filtered from the water. 

It is suggested that in the past these creatures would have traveled in small herds, occasionally coming to the surface to feast on the microorganisms in the shallower water. When the Carar bacterium was released onto the planet billions of creatures died, destroying the food source of the species. 

Story

The captive Sea Emperor is the last of its species, and a mother of five eggs. These eggs must be hatched at some point in the story. She is over one thousand years old, and is suggested to have far surpassed her natural lifespan.

Almost all Sea Emperors have died when the Carar was released, leaving one remaining adult and five eggs. The Sea Emperor, and her children are the key to curing Carar.

Data Bank Entry

SPECIMEN SIZE CATEGORIES HAVE BEEN ADJUSTED UPWARD TO ACCOMMODATE THIS SPECIES 1. Feeding & Digestion Despite its size this species subsists entirely on microorganisms it filters from the water. The mere presence of these microorganisms in such a restrictive environment is highly unlikely, depending as they do on a complicated ecosystem of plant and animal life. 2. Reproduction Since just one adult specimen of this kind has been identified in the field it may reproduce asexually, but it may equally be the last of its kind. Large ovary-like organs are carried in the middle section, suggesting that like other species on this planet it may produce eggs - but internal scar tissue indicates possible infertility. 3. Ambulation Seven vast tentacles mounted on the rear of the torso, in addition to two forelimbs, allow the creature to drag or propel itself in multiple directions. 4. Enzyme 42 Production This lifeform is the only known source of enzyme 42 on the entire planet. This enzyme is found in every living creature in the ecosystem, and seems to play a pivotal role in ensuring them against the impacts of the bacterium. Indigenous lifeforms, however, have adapted to utilize the enzyme in its natural form, and require a constant supply to survive. 5. Health Comparative analysis of size and metabolic rates indicates this specimen is more than 1,000 years old. Extensive internal and external scar tissue suggests it has lived well in excess of the peak lifespan for its species.

Future Plans

• Juvenile Sea Emperors and Sea Emperor eggs will be added in the future.
• The Sea Emperor will be scaled up by 4.5x its current size.^{[Citation needed]}
• The Sea Emperor will produce Enzyme 42 which will cure fauna and the Player of Carar.
  • Given this, it is most likely that the Sea Emperor is immune to the Carar.

Trivia

• The Sea Emperor currently uses the AI of the Boneshark and lacks certain animations. It can attack, inflicting 80% damage to the player's health.
• Once fully implemented, the Sea Emperor will be upscaled to be larger than the Sea Dragon Leviathan and it will become the largest life form of the game.
• Certain developmental notes refer to the Sea Emperor as the Emperor Leviathan.
• 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.
• The databank entry suggests that the last surviving Sea Emperor was kept alive well beyond its natural lifespan using unknown technologies, leaving heavy internal and external scarring (possibly even having lead to its suggested infertility).
• The captive Sea Emperor is a female.
  • This was teased before being revealed on a Trello card, with Scott "Obraxis" MacDonald referring to it as the "Sea Empress"
