Enhanced SensesEdit

Some mermaids may be able to touch, taste, smell and hear better than any normal human. Diana is the only mermaid who has shown this ability, primarily the sense of smell.

Communication with Sea CreaturesEdit

June and fish

June could calm a frightened sea lion and give it an injection which it feared. Fish were drawn to her and stared at her through their tank glass.

Mermaids Who Have Displayed this Power:

Siren SongEdit


Venus using her siren powers.

This power is currently used by Venus.

Venus is the only mermaid to exhibit this power, it is only accessed presumably by Sirens. It allows the user to hypnotize men into obeying their every command. This power manifests as a glowing aura around the user and they communicate through telepathy. Like the sirens of myth, mermaids with this gift may be able to access this power by singing.

Venus used this when hypnotizing a guard into letting her and her sisters to break into Mallick's were house and manipulating a police officer into letting Diana out of jail. Women and men who are aware of the a mermaid's status as a siren are immune to her power.

Sonic ScreamEdit


The power to create a sonic shriek that can shatter glass miles away and it send a cop to his/her knees in pain.

A mermaid is able to grow legs when he/she is dry, but if exposed to water will grow a long, blue tail. At low tide, wet or not, a mermaid's tail will appear and she/he will be able to get her/his legs back at high tide. It is possible that the legs only have to be exposed to water in order for the tail to appear because June is seen sticking her hand in water at the marine park. Mermaids absorb anything that hinders the transformation like trousers, socks and shoes. They reappear when their tails become legs.

Mermaids Who Have Displayed this Power:

  • All mermaids have this ability

  • All mermaids have this ability

Object of Power WieldingEdit

Every merperson is born with an Object of Power, a birthright that has distinct abilities.
