Leviathans are semi-aquatic entities that, like angorva, thrive in environments of plenty of water. Their skin secretes a slime-like protective layer and cannot be dry for long as they need moisture to function. These entities are anti-social and dislike contact with other entities, and most definitely survivors. Despite this, they are still tempted to enter the mall when flooded. They have relatively strong and athletic bodies, so they can swim without much fatigue.
