Subject class 223 spotted with a subject of unknown origin. Possible category— abyssal?

New subject appears to be of undocumented species. Bioluminescent membrane may be used in hunting, further research pending. Length of tail may point to relations with local snake species? Unlikely, research pending. Thin tail and visible bone structure may point to possible malnutrition/starvation.

Subject appears to be very young. Subject class 223 likely to assume paternal role again as he it did with [REDACTED]. Subject class 223 demonstrates remarkable tolerance with new subject, developing new behavioral patterns in response to that of the new subject. Integration into subject class 223’s pod pending? Further observation required.

Note to self: do not let [REDACTED] see. Redirect expeditions sw.

[puppetmaster13u]

Well, Mermay is almost done buuut, Aquatic batfam is always lovely. So which would you be fine hearing me ramble about-slash-work on the Oneshots lol

Eel Mer-   Eeels. Long wriggly friends. Now with apposable thumbs! And Bruce's growing adoption problem- and a slight family curse but shhh.

Merfolk-   I mean, fish! A mixture of modern and fantasy with the merfolk of Gotham waters being cryptids compared to the rest of the seas. The bats think it's hilarious.

Octopus Mer-   Octopi are fun. And you ever see the videos of octopus continuously escaping their tanks? Imagine if the octopi were vigilantes with weapons. Yeaah...

Crabtaur-  Lazarus crabs? Lazarus crabs! And a curse to them all that they have to work around in their day to day lives.

Nudibranch-   Sea Slugs? Indeed. And a lot of them poisonous and using the poisons in their work- along with messing with each other.

Mershark-   Sharks! Includes Flashpoint-esque Thomas being a murder grandpa and past AlfredxMarthaxThomas, along with Bruce being less murderous

Kraken-   Squids. Think giant merfolk but well, giant squids. Fantasy-esque AU with Gotham being the largest population of pirates & crime on the seas.

Sea Dragon- Sea serpents mixed with seahorses and a bit more. Includes the kids being bio-kids via blood ritual and a couple galas. Also some shapeshifting.

mer Jason and Poison Ivy prompt

The Mangroves provide food, shelter and maintain the land. For that reason, the sirens of the mangrove swamp and its surrounding lakes and rivers reveer the trees as sacred offspring of the original World Tree. They live in giant mangroves with cloth or straw forming roofs. Their leftovers and droppings help to fertilise the trees, and the smaller mangrove roots provide a safe place for guppies to play.

To desecrate or, heaven forbid, destroy one of these trees is invite to invite the siren’s wrath. But one of the older kids dared him to do it for 50 whole dollars. Jason just needed to go in, spray some rude message, and get out. And he’d be able to afford warm meals for two weeks.

That was until Poison Ivy caught him. Jason’s body twists into agony. scales and fins burst through skin. For his crime of despoiling the sacred grove, Poison Ivy owns him now, until his debt is repaid.

“What’s your name?”

"Batman," he startles when Duke laughs louder than he really meant to.

“What kind of a name is that?” he giggles, wiping a stray tear from his eye. "Isn't that an animal?"

or: bruce saves a helpless merman and gets bullied relentlessly for it.

Batfamily Week Day 5: KING’S GUARD

Fantasy AU | Friendship/Team Bonding | “There’s more of you?!”

[REDACTED] came and handed me footage of the pod in… startlingly good quality. I am not sure as to [REDACTED] motivations, but I won’t be letting my guard down. There’s too much at stake. I won’t do that to them. To him.

[REDACTED] did not comment the footage and left again just as swiftly. He also left me a small folder of drawings of the pod. I have taken the liberty to add some notes to them. I won’t deny that I am unnerved by [REDACTED] response to… well, I suppose I may just as well say it. A traitor.

[REDACTED] has never been anything but loyal to [REDACTED]. This apparent “change of heart”… I don’t buy it.

But I won’t deny that I’m also a little grateful. These weeks without any sightings of the pod have made me anxious.

…. Did [REDACTED] notice?

the fic i'm writing is. eating my brain

In honor of mermay, but not related to any prompts:

“I don’t trust that guy,” Jason narrowed his eyes, jabbing a finger at the weird not-human and his half-human son chatting with fully-human Bruce and fully-human Alfred.

“Relax, Jay,” their fully selkie not-human brother drawls with his legs in their giant pool filled with aquarium-grade water, “It’s just Uncle Clark with his son.”

Tim shrugs, “I dunno, they look weird… and smell weird. Cass says theyre- and I quote- really weird, if Cass says they’re weird? Sorry, Dick, they’re weird.”

“So…” Dick puts on a cheshire smile and leans forward, “you can even say they’re Super -weird? Eh? Wha- AUGH!”

Tim yelped, flinging himself out of the pool as Jason lurched forward to yank the selkie into the water. Cass was laughing below the surface, a wide smile on her face as Dick floundered and screeched. Jason had his claws hooked into the selkie’s pants with a bright grin.

“BRUCE!” Dick screeched, the sound of struggle clear within this floor of the manor, and Tim pulls his caudul fin out of the water in disgust, “ALFRED! HELP, I’M- AUAGDHGAGAHDHFPFPSPFGSAGO—”

“What is going on here?” Bruce walked over to examine the scene with an incredulous expression, “Jason, let your brother go!”

The lionfish mer hissed in displeasure, but released the selkie after a stern look from the butler.

“BRUCE!” Dick gasped dramatically, clawing himself onto the floor. His Pelt remained dry, but everything else about Dick was sopping wet. There was even a puddle forming under him.

Tim eyed him warily, flattening his cranial fin as Damian approached with the other half-human, half not-human spawn of the not-human Dick had named “Clark”.

“Grayson, cease you incessant chatter,” Damian huffed before addressing his… “friend”, “Jon, feast your eyes upon our mers.”

The older human walked over while Bruce ranted to Clark about his children’s “dramatics”. Meanwhile, Damian was still talking, “Timothy is a pedigree mer. He is born of a prestigious bloodline, and his scales echo his worth. The previous humans he resided with were not providing him with the proper enrichment a mer of his value should have, and so Father rescued him.”

Tim grimaced at the human’s description before glancing at his red-dappled tail, “Thanks?”

“What do you have to say about me?” Jason swam over and propped himself upon the ledge of the pool with a grin.

Damian sniffed and gave Jason a side-long glare while “Jon” giggled.

“He looks pretty,” the bright boy commented while his… brother(?) hummed.

“I think this guy looks prettier, kinda like a koi.”

Jon examined Tim’s tail before nodding, “Hmm, you’re right!”

Tim frowned, feeling suddenly self conscious at the attention.

Damian sniffed, “Please do not scrutinize Timothy! He is a sensitive mer, and I will not allw you to unsettle him! Jason, on the other hand, is hardier- though I advise you to keep a healthy distance from his spines. His piscine breed is that of a lionfish-”

Jason grins and flashes his fins like the show-off he is.

“-and Father rescued him from an illegal mer trade,” Damian finished.

“What about her down there?” the older half-human asked, peer down at Cass, who popped up to wave and tap Tim’s tail. With a smile, he flicked his tail and artfully drenched the older half-human with the pool water.

“Kon!” the little one exclaimed in shock, and Tim darted away before Bruce coild spot him.

“Jason!” Bruce called again, “We don’t splash guests either!”

“But-!”

“I doesn’t matter if he was annoying, we don’t splash guests!” Bruce sighed in exasperation before returning to his conversation with an amused Clark and an equally entertained Alfred.

Damian continued on with his infodumping, “Cassandra is a mer who escaped from a facility ran by my grandfather, who was trying to create the ultimate weapon for marine warfare.”

“Oh!” Kon blinked in surprise, “That… was not what I was expecting!”

“I kinda feel bad for them,” Jon commented, but Jason waved him off.

“Don’t worry about Cass. If she was in any real danger, she’ll just electrocute you and then rip your throat out!”

“That’s so cool!” Jon chirped eagerly while Kon remained slightly peturbed.

Tim shrugged, “I guess, but it’s kinda… just our lives. Dick has seen so much more of the world than any of us.”

“Maybe, but he’s an asshole,” Jason replied and Cass nodded in agreement. The selkie jerked upright with an affronted gasp and a mock-offended expression.

“Excuse me! I am not an asshole!”

“Mhm, sure not,” Jason countered with a flap of his hand. Before Dick could continue his defense, Bruce approached once more with Clark and Alfred at his side.

The not-human helped Dick to his feet before addressing the two half-human boys, “Alright, boys. It’s getting pretty late, so we should head back to the farm before Ma and Pa worry.”

The boys chorused their agreement before… floating and flying out of the manor? Tim thinks that not-human and his half-human sons were weird.

Bruce took in a breath before kneeling down in front of them, “Okay, kids. I know your thoughts on strangers in the manor-”

Jason interrupted with a flat expression, “If they weren’t kids, then I would’ve stung them.”

Tim huffed as Bruce’s expression tightened, “Okay, I wouldn’t have done something as extreme as Jason, but I really don’t like strangers in the manor… I kinda don’t mind that Kon, though.”

“What?! Tim!” Jason gasped in offense and Tim groans.

“Shut up, Jason! He had shiny things, okay!”

“Timmy has a crush!” Cass teased swimming over to wrap herself around Tim’s torso and drag him underwater. Very wisely, Tim decided it was in his best interest to not fight with the electric eel.

“Ugh, I wish I’d sting him sooner!”

“You will not be stinging anyone,” Bruce admonished, and Tim could hear Jason boo in dissatisfaction before joining Cass and Tim underwater.

“Father, I support Jason’s idea,” Damian chimed in, “we should allow him to sting Timothy’s potential paramore, for Timothy is a regal creature and shall not be paired up with such a thing below his standing!”

Tim groans in exasperation, the sound echoed by Bruce as he thrashed his red-white tail. Suddenly, the water churned and a ringed seal joined them in the pool, his eyes bright with mischief and whimsy.

As Bruce watched his fish (and seal) children tussel together underwater, he pulls Damian close against his side. Alfred rests his hand on Bruce’s shoulder, and the man cannot help but marvel at how far all of them have come since their first introduction into this… messy and patchwork family who now all call the Wayne Manor home…

Bruce could not be happier.

(here’s like, the prequel)

Another mermaid BatmanAu

Superman and his giant wife

(Bruce with the tinny weird man that brings him flowers)

The batbrothers with their dad

In this AU only batfamily members (and the al Ghuls) are Mermaids (except Alfred, I will talk more about it later)

Bruce : Deep water Siren

Dick : Surface Siren

Jason : Can live in both, but surface Mermaid.

Tim : Arrecife Mermaid

Damian : Deep Ocean Siren

The reason Bruce lives so close to the surface is because of his sons; none of them (except Jason) can live in deep waters, so Bruce is forced to live near the surface. This is not good for his health, but he ain't telling and no one is asking.

He was raised by Alfred, a navy soldier who dedicated his life to operating submarines on solo missions. Alfred would always visit Bruce when he was little, but once he grew old enough and Alfred retired, Bruce would be the one doing the visiting. After retaiment fron the navy, Alfred became some kind of mermaid biologist, but really lives from his retaiment money and doesn't publish his works.

Near the shore, where Alfred lives, during one of Bruce visits, is when the Graysons are killed, and Bruce adopts Dick.

When Dick begins his migratory travels (his species being migratory, and there's no fight with Bruce about it), Bruce meets Jason, who was orphaned because his mother died from a chemical spill near Gotham, and his father was killed by the coast guard for sinking ships for human mafias. Tim joins after Jason is (incorrectly) assumed dead by poachers. His mother died during labor, and his father is never present in his life, only visiting occasionally to bring food. Tim is both scared and admires Bruce, who is called "The Bat" by humans because, since Jason's death, he has been sinking all kinds of ships that get close to Gotham's shore. Damian joins after being kicked out of the al Ghul family because he didn't inherit any of Bruce's genes and wasn't of the same species. Instead, he ends up as a barracuda like the rest of his family, just a darker color.

Bruce is somewhat of a local legend/hero in the city of Gotham because he would save boats from poachers and pirates, as well as sinking contraband ships. But during his time sinking ships after the "death" of Jason is when Superman and the Justice League hear about him and think there is a monster in Gotham waters... but in the end, he falls in love.

The only one who can actually talk with the family is Aquaman, so they have a good friendship.
