Dimensional Horror (The Tomb from Beyond)

Dimensional Horrors are a predatory species originating from another dimension. The people of the ancient city of Dras in Borneo created a mausoleum that acted as a dimensional gateway to allow these creatures to pass through.

Biology
Dimensional Horrors are large aquatic predators, similar to a mosasaur or other Mesozoic reptile, but with eight spider-like hairy legs, black hyalescent eyes, and skin covered in slime. They make hissing noises. They can be killed by fire.
