The Sea Emperor leviathan was a passive leviathan in the video game Subnautica.
It looks a lot like the Sea Dragon, but there are a couple things different about this one. It's skin color is mostly brown with some black. It has blue two blue eyes in each side and hooked ears. It does not have any attacks, and it is only found in one place, The Primary containment facility.
The Sea emperor's food chain is micropods. After the explosion of the Aurora, there was not much food left. It's history is that there was once millions of sea emperors, but they got destroyed when the Aurora crash landed on Planet 4546B. Now there is only one left.
