15. Frankenstein’s Monster
- Fictional: Frankenstein; or, The Modern Prometheus
Unlike other top monsters on this list, people tend to often misunderstand the name of the creature. Known mostly as just “the monster,” it would eventually come to be known as “Frankenstein’s Monster” due to being created by the scientist Victor Frankenstein. First coming into the world of fiction in Mary Shelley’s 1818 novel known as Frankenstein; or, The Modern Prometheus, it was eventually made into a motion picture several times in the 1900s. Shelly was just 18 when she first started the book and it was published by the time she was 20 years old.
