In some cases, their singing is simply so beautiful that listeners want nothing other than to continue listening to it, potentially endangering themselves through this selective obliviousness. The precise nature of these voices can vary. Their most iconic power is their enthralling voices. Regardless of type, their human parts are typically extremely beautiful, ranging from being very attractive, to appearing very attractive to those who have been at sea for a long time, to using illusions to cover up a very unsavory reality. In Classical Mythology, they were strictly women-faced birds fully humanoid portrayals date to Roman artwork, and the mermaid-like appearance first cropped up in the Middle Ages. This third type is further divided between two common appearances: feathered humanoids with wings as a third set of limbs, and giant birds with human heads.

In appearance, they typically have one of three portrayals: some resemble regular human women in all physical aspects, some are mermaids with the lower bodies of fish, and some are part avian instead. Sirens are beings, usually female (male sirens did turn up in ancient artwork, but were very rare) and at least partly human, who use their enthralling voices to lure people to their doom.
