Reaper Leviathan

The Reaper Leviathan is a large, hostile creature.

The Reaper seems to move around its prey for a few seconds before attacking. Currently the Reaper doesn't harm the cyclops, though it has enough strength to push it.

It can currently be spawned using the command SPAWN REAPERLEVIATHAN.

If fins and head protrusions are included, the Reaper Leviathan currently is about 2.5 times as high and about 2 times as long as the Cyclops.

The Reaper spawns around the Aurora, usually alone. This creature spawns rarely because it is so dangerous.

Abilities
The Reaper Leviathan is able to instantly kill any players it attacks outside of their submarine. The Reaper Leviathan is also able to grab the Seamoth and shake it around. Unmanned Seamoths inside a Cyclops can also be attacked, as well as the player while piloting. This is most likely a bug. If you approach it with the Seamoth, it will grab the Seamoth and shake it around, doing 2-5% damage before letting go. The Reaper Leviathan has been observed to smash the Seamoth on the ocean floor and destroy it completely after shaking it around.
