It was said that a mermaid/merman had the head and body of a human and the lower half of a fish. They also lured sailors to their horrifiying death . They also didn't have a particular size . Now as for Lycans their a another name for werewolves. But what if mermaid and werewolves could mate. It could just be possible if the maiden or gentlemen could gain legs. Its not strange for creatures of the night to mate n have sex either at all.
It often make you wonder how mermaids can walk on
land is it because of the moon or they just can!
