Sirena is one of the main characters in Mako: Island of Secrets. Sirena is the mediator and the peacekeeper between Nixie and Lyla. She's a really beautiful soul and bit naïve, but that can sometimes work to her disadvantage.


Sirena grew up in the Mako Island pod, and has been Nixie's best friend since they were hatchlings. She is very close to her sister Aquata and is very upset when she and the pod left her, Lyla and Nixie by themselves on Mako to sort things out.


Sirena is a little naïve, very trusting, can be unsure of herself at times and is easily treated like a doormat. Where Nixie is the leader, Sirena is the follower. She is loyal almost to a fault.

She's a little clumsy and of all three mermaids, struggles with legs the most.

Sirena is initially cautious around Lyla, but quickly realizes that they'll all need to stick together to succeed on land. With Nixie and Lyla always at each others' throats, Sirena plays the role of mediator, but often wishes she wasn't stuck in the middle.

Although she's normally patient with them, sometimes it all gets too much and Sirena snaps, Lyla and Nixie don't want to be around when Sirena loses her temper!.

Although the others rarely pay attention to what Sirena has to say, she has sometimes come out of left field with a streak of genius that can help them find their way out of sticky situations. As the series progresses, placid Sirena gradually earns the other mermaids' respect as an important member of the group.

In season 2, Sirena is noticeably more confident and strong headed than she was in the previous season. With Lyla and Nixie not around, she is placed with a lot of responsibility and leadership on her shoulders as it comes to introducing Mimmi and Ondina to land. Sirena also seems now to be a little more competitive, though her determination to fight is not often for herself, but to defend someone else.


Sirena has golden blonde hair and beautiful blue eyes. She is medium height and very slim. Sirena wears girly, dressy clothing often in pinks or whites or blues.

Mermaid Powers

Sirena possesses the ability to transform into a mermaid ten seconds after physical contact of water. Once her body is completely dry, she turns back into a human along with the outfit she was wearing before she transformed. As a mermaid, Sirena has the ability to swim at super speed of 600km/h, hold their breath for more than fifteen minutes, and possibly dive at a depth lower than any ordinary human being. 


She used it in Zac's Garage so that she wouldn't be spotted by Zac's parents in "Getting Legs".


In "Zac Returns to Mako", Sirena makes the boat move by controlling the water while she was swimming.


In "Meeting Rita", Sirena helps Lyla and Nixie to dry Zac.

Siren Singing

In "The Siren", she sings the Enchantment Song to David which was meant for Zac and the song made him follow Nixie and want to please her until she broke the enchantment with a particular shell.


In "Aquata Returns", Sirena uses this power to send the Trident out of Zac's hands and into the water and Nixie and Sirena were then shown using this power to send Zac flying.


Sirena is shown using this power in "Battlelines" to make a storm in a jar, she makes the cloud but loses control over it. In Stormy Seas, she and Ondina have a contest of mermaid powers and she used Ondina's own storm powers against her
