Sea Dragon Leviathan

The Sea Dragon Leviathan, more commonly known as the Sea Dragon, is a colossal life form belonging to the fauna category. It is also the largest aggressive creature of Subnautica.

One thousand years ago, a Sea Dragon Leviathan was captured by the Precursor race and contained within the Secondary Bio-Research Facility, however, it managed to break out its confines and laid waste to the facility, resulting in the Carar bacterium being released onto Planet 4546B causing the Precursors to put the planet into quarantine

Appearance
The Sea Dragon Leviathan 's body mostly resembles the Sea Emperor, albeit slightly smaller, slimmer in design, and is dark green in color, along with purple accents on its limbs and head. Many of its body parts are adorned or spotted with orange bioluminescent glows, and many small spikes line its lower jaw and arms.

The head of the creature is stout and reptilian, possessing two pairs of glowing orange eyes with white pupils. The mouth contains sharp teeth, visible even when the mouth is closed. The tip of the snout features two short protrusions with orange glowing tips. It also has a second set of larger fin-like protrusions under its lower jaw.

Along the side of its body runs two long, dotted trails that emit bioluminescent glows. Its rear-side consists of seven tentacles ending with small tentacular clubs, with the largest being surrounded by the other smaller ones.

The Sea Dragon's forelimbs are long, having large webbed hands consisting of four fingers as well as a pair of extra digits behind the forearms, with sharp claws for each finger. There are two fin-like extensions on its head as well as a single dorsal fin.

Behavior
The Sea Dragon Leviathan uses its arms and tentacles to swim in the water. It will attack the player with its arms if they are on either side of its front body by swatting them away. However, the swat does not harm the player; it simply knocks them away.

If the Sea Dragon Leviathan attacks the player with its mouth, it will swallow the player, killing them instantly.

Occasionally the Sea Dragon Leviathan will open its mouth wide and fire a rock at its target as a projectile attack. The Sea Dragon Leviathan is also capable of firing a barrage of small "fireballs" covering a large distance.

The Sea Dragon Leviathan will grab the Seamoth with its hands, and shove it inside its mouth, doing 5% damage per second. The Sea Dragon Leviathan will sometimes release and throw the Seamoth after swimming around with it for a while, often leaving it below 20% health instead of completely destroying it.

The Sea Dragon Leviathan will attack the Cyclops by pushing it around with considerable force, often leaving the Cyclops upside down. It can't damage the Cyclops currently; it can only push it around.

Future Plans

 * The finished Sea Dragon Leviathan is planned to be capable of inhaling the player, inflicting massive damage and perhaps even immediate death.
 * The Sea Dragon Leviathan is planned to spawn outside of the map borders, in the Void, as a means to discourage players from leaving the map.
 * The PRAWN Suit will be used to combat the Sea Dragon Leviathan.

Trivia

 * While shown in the concept art to be considerably larger than the Sea Emperor, the Sea Dragon Leviathan will be implemented to be smaller than the latter in the future updates.
 * The sounds of the Sea Dragon Leviathan were created by combining real sounds from a bull, an elephant and a tiger.
 * The Skeleton in the Lost River is suggested to be a close cousin to the Sea Dragon Leviathan.
 * Even though it's obviously endemic to the ILZ and the ALZ, it will also spawn in the Void. This suggests some route between the two lava zones and the map borders.
