Sci-fi creatures are often featured in science fiction films, books, and television shows. The term 'MONSTER' is often used to describe a creature that is large, dangerous, and often has supernatural powers. The term 'BLOB' is used to describe an amorphous creature that is usually made up of a gelatinous substance. Both monsters and blobs have been featured in many sci-fi stories and films, often as antagonists or villains.
