Summary
Zipp would say she was a logical and calm pegasus.
So how in Equestria did she end up on the edge of drowning while face to face with a being thought to be lost to time?---
I wrote this after reading a lot of mermaid AUs on different fandoms. Anemone is a character from the G5 set your sail comics and sadly she does not have a tag on AO3.
Might write another chapter if I feel like it.

*REUPLOAD FOR A MOOT OF MINE. THIS WAS SITTING AROUND IN MY DRAFTS FOR THE LONGEST TIME BEFORE I FINALLY GOT THE CHANCE TO GET IT OVER WITH*
This is a AU of my OC and Nikto once more.
In this AU, there’s a post-apocalypse happening. During the span of this story, it goes back and forth between their perspectives. So at one point, it’ll be written from Mei’s side of the story before switching over to Nikto’s.
I was playing Mermaid Isle on Roblox and got inspired lol, y’all should play the game if you get the chance to.

Summary
“What’s this for?” He asked, inspecting the sand dollar closely. Maybe it would blow up in his face.
The mermaid cleared her throat, and looked away. “It’s payment. For helping me,” she mumbled.
Ekko raised a brow. Normally, he’d be more charitable, but his sleep-deprived mind was in control. “Pretty sure they’re only valuable underwater?”
The mermaid snorted, slightly disgusted with him, he could tell. “If you ever need help, snap it in half, and it’ll come.”OR:
Ekko was always convinced he would become a sailor and make the sea his home. A dream that died the moment his mother drowned on a voyage, lost to storm-tossed waves. He now lives on the edge of Zaun, operating the little lighthouse that guides ships home. That was the most he would ever love the water. That was the closest he would get to the sea.
Until one day, he saves a mermaid….
…and the sea starts to get close to him. -

Summary
Anduin Wrynn had pretty much been confined to Stormwind City his entire teenage life so far, yearning for adventure onboard the multiple ships that come and go from their port. He heard stories from the sailors that returned with his father, and he had read so much of the world, just to never have been allowed to witness it with his own two eyes. Until finally he manages to beg his aunt, Captain Jaina Proudmoore, to talk his father into allowing him with her on a routine business trip to Booty Bay and back on her ship. What Anduin expected to find was a fun little adventure to the multicultural port city, and instead what he found was possibly the last black tailed mermaid on Azeroth. The only one his father had not yet killed.

Summary
A seagull soars overhead. Waves crash against the dock. The ocean breathes. Changbin waits.
“I had a friend named Changbin once.” Jisung’s voice cracks halfway through the sentence. His chin wobbles. “But he—he died.”
Changbin holds his gaze, watching as recognition dawns over Jisung’s round features. Timid, careful, desperate. Ages of heartache in a single look.
“I had a friend named Jisung,” he says softly. “He died, too.”
-
or: childhood best friends changbin and jisung were inseparable until one tragic night tore them apart. when jisung returns to town years later, desperate to cure his writer's block, changbin's double life as a mermaid hybrid becomes harder and harder to hide.

Summary
In a world underwater, Wei Wuxian has never known anything but living in Lotus Cove with the Jiangs. They were his clan, his family, no matter how dysfunctional.
Enter Lan Wangji, the Second Serpent of the Lan Clan, who makes Wei Wuxian's heart flutter in ways he didn't know possible.
Through mischievous antics, bogus competitions, trials and tribulations, war and tragedy, the two can never seem to catch a break from the other.
Even death cannot put a permanent barrier between them, it seems.

Or, an MDZS merpeople AU. Aside from the mermaid traits, most of this story follows canon with a little extra sprinkled in, such as graphic gore and violence, original characters and backstories (including ones for existing characters), and a whole bunch of lore (and wherein the title may be a spoiler but oh well).

Summary
Seokjin has warned him time and again to be wary of humans and their traps. Namjoon, however, has told him a different story. Has told him of the humans' curiosity and kindness, of their neverending creativity. Jeongguk likes that version much better. And honestly, how could he ever fear Taehyung, let alone loathe him? How could he ever do something else than loving him with everything he has?
Or
When Idol Taehyung requested a timeout and moves to the most boring coast town he can find, he certainly did not think he'd come eye-to-eye with a living miracle there. Let alone fall in love.
This is part one of the series "Children of the sea" and contains the main arc of the story about merman Jeongguk and idol Taehyung. Of course you can read other parts of the series first, you do you, dear reader, but a lot of things probably won't make sense. At all. So, I highly recommend you read this main story first before you move on to other parts of the series, which will be more, like... sequels. Thank you ^^

Summary
He had been warned to stay away from humans. His parents were raised believing if a human caught you they'd eat you, and he was raised under the same belief. When he had found this cove and this rock, there was no sign of human life around it whatsoever— not like the beach a few miles down, lined with docks and a long pier that stretched into the sea. All merfolk knew to stay away from there.
Here, Satomi thought he had been safe.
