As Izuku aged the merman never left the back of his mind it was one of the reason why he decided to become a marine biologist.

Specks of Gold Against the Ocean's Waves by Serah_chan

Summary: While enjoying the light of the full moon, Katsuki Bakugou, an orange tailed merman, crosses paths with a handsome surfer with freckle littered cheeks. While he's not supposed to interact with the human, there's something about them that draws the merman to get close and ignore all boundaries.

“Huh, he’s kinda good looking for a human.” Katsuki muses, feeling the annoying itch of curiosity push him towards getting a better look. He wonders if he can observe him from down below as he takes on the waves, catch glimpses of him as he falls back to the water. Human eyes weren’t exactly the best anyway, so he shouldn’t have to worry about being seen... right?

what the water gave me by twinstarsies

Summary: "It's like I'm challenging fate," he says to a hermit crab he finds tucked into a crevice in the rock. "I'm daring it to knock me into the water just to show me who's boss. At this rate, it's probably going to win." 

"Something's gonna knock you into the water, alright, but it won't be anything as nebulous as fate," a voice says, tone wholly unamused. 

Izuku startles so hard that he forgets to use his quirk to catch himself as he slips from his perch on the rock into the ocean.

Izuku goes on a forced vacation and meets the love of his life.

Call of the Siren by Gemsom

Summary: Izuku always imagined that sirens sang their victims into the water, and that their helpless victims could do nothing to resist. He almost wished that was the case.

Every time his captain’s ship crossed the narrow sea, Katsuki came to see him. The siren's friendship seemed so genuine, but Izuku was smart enough to know that the creature was sweet talking him to his death. Katsuki never denied it either - asking over and over for Izuku to offer his life.

Of course, Izuku had no way of knowing that the siren planed to give him a new one in return.

Shipwrecked by Withstarryeyes

Summary: When he wakes there is a man above him. He’s backlit by the sun, features blurred out by too much light, and Bakugou shifts upwards abruptly. The man slinks back, but lingers, hands outstretched as if he’s afraid of what Bakugou might do. In the background, waves crash onto the sand, and Bakugou turns, searching for his ship, for his crew. He screws his eyes shut, breathing quickening as he remembers the storm and the feeling of the deck on the waves. Something cool connects with his cheek and Bakugou opens his eyes, scrambling backward without thinking.

Home is where the waves crash by tiredwrites

Summary: Izuku thrashes in his cage, the fins that line his large tail flare with a dangerous purpose. The claws his fingers taper into slice through the water and catch the light that filters into the clear water of the aquarium tank he's in.

His gills flare in irritation as he flips around, muscled tail ramming into the three-inch glass barrier with a thundering BAM!

Bioluminescent sacs under clear scales flare and glow, flashing a brilliant toxic green. The team that had brought the merman into the tank watch the mer flail and roar, flexing the powerful jaws that can often unhinge, like a snake.

Sand is Land and Sea Inbetween by Frost_or_Fire

Summary: Katsuki is by no means a marine biologist, really, and he knows that he could just walk away and act like he saw nothing. Act as if he didn’t see a half-human body laid across the late October sand while a black tail is still in the water, sorta concealed by the rolling waves that washed over the figure. He could just act like this is all just some dream that his subconscious cooked up for him to be put through to show how miserable he actually is.

But Katsuki fucking Bakugou is anything but a coward and a sick person.

----

Bakugou finds a Merperson on a beach and takes them home to help with their injuries, and possibly get more than he bargains for.

Save to Swim by sanjusangendo333

Summary: Izuku is out for a run, when he spots a blond man in distress in the river. He quickly strips off his shoes and clothes until he's barenaked to save him. But Katsuki is not in distress and nor is he a regular guy. He's one of the men from the elite diving unit of Japan’s coast guard who is in the middle of diving exercise.

Katsuki and his unit all agree that, ‘WOW! Izuku can swim really well and so fast!’ He'll really fit well in Katsuki's diving unit, they all say as Izuku is still in the water. But Izuku hurriedly excuses himself and swims away, because otherwise, they'll see the fish tail that his legs transformed into the moment he dived into the water.

Katsuki, of course, does NOT give up on trying to recruit him.
