Series: Mako Mermaids An H 2 O Adventure

Just add water. Again!

A Spinoff of the popular Australian fantasy series H2O: Just Add Water, Mako Mermaids follows the life of three mermaids and teenage boy turned merman. Sirena, Lyla, and Nixie were three young mermaids charged with protecting the small magical island of Mako during the full moon in order for the rest of their mermaid pod to perform their moon rituals. Unfortunately young Zac falls into a mystical pool on Mako during a full moon and interrupts the sacred ritual, thus granting him merman powers, but causing the three young mermaids to be cast out of their pod. Equal parts comedy and drama, the series starts off with Sirena, Lyla, and Nixie attempting to remove Zac's powers so as they can rejoin their mermaid family.

As of the second season, a few changes have been made to the cast line-up. Lyla and Nixie have left the show, and are replaced by two new mermaids named Mimmi and Ondina. A new merman, named Erik, is introduced as well.

The second season follows the girls' continued efforts to remove Zac's powers, Evie's efforts to adjust to the changes in her life, and Zac and Erik's attempts to uncover the secret of the newfound Merman Cave on Mako Island.

The first and second seasons are available on Netflix.

Tropes Found in Mako Mermaids.

  • All Women Love Shoes: Nixie starts a fight with Evie over the "perfect shoes" in Lyla Alone.
  • Ambiguously Evil: Erik appears to be plotting something terrible, but he might just be interested in the Merman Cave because of its significance to merman history.
  • Artifact of Doom: It's claimed by the mermaids that the trident is a force of ultimate destruction and evil no matter who wields it. Naturally, it has to be destroyed.
  • Big Damn Heroes: Zac gets one in in the season 1 finale when he stops Cam from destroying the moon pool.
  • Bookcase Passage: In the third episode the girls find one in Principal Rita's home that leads to a secret passage to the sea.
  • Continuity Nod: Scenes with Zac are similar to scenes from the original series.
    • Zac drinking floating bubbles of water from the air was originally done by Cleo.
    • Like Emma, Zac had a promising watersports career which was brought to an abrupt end by becoming a merperson.
    • When Zac tries to stop the surprise pool party, he starts to boil all the water in the pool away, which was done by Rikki to get revenge on Miriam for being, well, Miriam.
  • Dangerous Device Disposal Debacle: Twice. The trident was supposed to "never be unlocked again", and later, when Lyla hides it, it takes Zac all of an episode and a half to find it again.
  • Defrosting Ice Queen: Lyla is definitely the harshest of the three leads at first.
  • Elemental Powers: Much like in the original series, Mermaids have a whole host of sea and storm related powers that allow them to control water and wind.
  • First Law Of Thermodynamics: Blown to pieces between the nineteenth episode and the twenty-third. The trident charges up by partially draining one moonring, is used a few times, and yet it still has enough power to charge up three moonrings.
  • Freudian Trio: in the first few episodes it seems that Nixie is the Id, Lyla is the Superego, and Sirena mediates between the two, but the remainder of the series seems to have Lyla and Nixie reverse roles.
  • Great Offscreen War: Sometime before the start of the show, there was a great war between mermaids and mermen, which is why most of them today have considerable animosity for one another.
  • I Am Who?: It turns out that the reason Zac is able to manipulate the Merman Cave is because he was always a merman, and the trip to the moon pool broke the spell keeping him human.
  • Island Base: The mermaids use Mako Island as their go-to hideout.
  • Island of Mystery: Mako Island is home to a number of weird things, including the Moon Pool, the Merman Cave, and the cave that leads to the trident's storage area.
  • Local Hangout: The café.
  • Long-Lost Relative: In the Season 2 finale, Zac and Mimmi learn that they are siblings.
  • Love Triangle: Type 4, at least early on. Carly likes David, but David and Sirena are clearly head over heels for each other.
  • Lunacy: Merfolk get the energy for their magic from the moon, and one can become a merperson by being in the Moon Pool on a full moon. Furthermore, inexperienced merfolk can be overwhelmed by the full moon's power, lapsing into a trance or drugged-like state.
  • Magical Girl: Four of them, and two magical boys.
  • Magnetic Plot Device: For some reason, the mermaids just can't seem to keep people off Mako Island.
  • Manipulative Bastard: Cam becomes this in the final three episodes of the first season.
  • Meaningful Name: By the boatload. Nixie is a Germanic water creature much like a mermaid. Sirena is related to the Greek Sirens, which are sometimes mistaken for mermaids. One origin of the name Lyla is a term to refer to someone who is from an island. "Ondina" is a genus of sea snails.
  • Mermaids Out of Water: The girls' first voyage on land is a literal interpretation of this trope.
  • Mr. Fanservice: Zac and Erik, by virtue of being mermen.
  • One-Gender Race: Averted in Season 2, when it's revealed that mermen are alive and well - they just live separately from mermaids.
  • Only the Worthy May Pass: Only a "true" merman can get into the merman cave.
  • Our Mermaids Are Different: Like in the original series and films like Splash, a dry mermaid has human legs and a wet mermaid has fins. Mermaids also hold Elemental Powers and magic, and there are different varieties of regional mermaid.
  • Secret Keeper: Cam is this for Zac. It's particularly hard for him to be so, because Zac initially wants to reveal his powers and be a superhero. Lyla manipulates events so the mermaids also become this for Zac, but they already knew he was a merman
  • Shout-Out: Aquata is the name of another mermaid who was also a sister of a main character (Ariel) in The Little Mermaid.
    • Erik also shares a name with a Little Mermaid character.
  • Spoiler Opening: The fact that Erik is a merman might have been a pretty major plot twist if they hadn't shown him with a tail in the opening credits.
  • Suspiciously Similar Substitute: Down-to-earth and cautious Nixie, for Emma; naive Sirena, for Cleo (with better non-magic singing skills, actually); and stubborn and impulsive Lyla, for Rikki.
  • Wham Line: "Do you realise what would happen if the son of Nerrisa controls the power of this place?"
