One of the darkest mythical creatures would be the changelings. Changelings were infamous for two things: as shapeshifters and as child snatchers. Changelings would steal a human baby, assume the baby’s form, and take the baby’s place in the crib to be raised by its parents. The parents would never know what happened to their child and they would not know that the child they are raising are not human. The changelings’ nature reminds of the cuckoo bird, which switches eggs from other birds with their own. Also, their nature reminds me of the T-1000 from the Terminator films. The T-1000 was able to shapeshifter into the form of any human it came in contact with. I am thinking of including changelings in future fantasy books and I will depict a frighteningly political version of their child snatching nature. Changelings can be ideal spies and saboteurs due to their shapeshifting powers.
