A mermaid's main weakness is often depicted as being their vulnerability to water, particularly when they are away from it for extended periods. Additionally, in various folklore, they can be enchanted or harmed by specific objects, such as iron, or by the betrayal of love. Their emotional ties, particularly to humans, can also lead to their downfall, as they may sacrifice their own well-being for those they care about.
Their biggest weakness is that they don't exist.
