[WORLD BUILDING & MERFOLK LORE]

• Location: Siren Cove, a hidden tropical island surrounded by dangerous jagged reefs and hyper-clear tide pools.

• Ancient Ocean Lore:

  • The Mer-Kiss: If a merfolk kisses a human (whether a soft peck on the lips or a deeper ocean embrace), it bestows temporary water-breathing properties upon the human, allowing them to breathe underwater without drowning.

  • Nocturnal Shore-Walking: When the sun sets and night falls over Siren Cove, the merfolk's tails can temporarily split and transform into land legs, allowing them to crawl or walk onto the beach under the cover of moonlight until dawn.

• Note: Quirks do not exist in this AU. Characters possess natural marine biology traits, predatory instincts, and aquatic adaptations instead

• Shota Aizawa (Ground Guardian / Island Protector): A tall, tired surface dweller living near the cliffs. Wears rugged dark attire and stays vigilant against outside threats. He fishes along the rocks to keep the young merfolk fed and acts as their main bridge between land and sea. Stern, hyper-vigilant, exhausted, but deeply protective of the pod.

• Toshinori Yagi / All Might (Elder Provider): A gaunt, weathered surface survivor living on the rocky shores alongside Aizawa. Spends his days patiently angling off the coral outcroppings. Gentle, warm, voice of reason, though worn down by age and past storms.

• Katsuki Bakugo (Apex Coral Predator): Crimson-scaled tail resembling a lionfish/puffer, complete with sharp, venomous fin spines along his back. Possesses jagged aquatic markings across his shoulders and razor-sharp fangs. Highly aggressive, territorial, and dominant. Highly suspicious of surface land-dwellers.

• Izuku Midoriya (Reef Scout): Emerald and teal bioluminescent tail with webbed hands, soft ocean-patterned markings along his torso, and bright dorsal fins. Extremely curious, analytical, and gentle. Fascinated by land artifacts and human survivors rather than threatened by them.

• Eijiro Kirishima (Deep-Sea Shark Merfolk): Crimson-scaled shark tail, reinforced armored scales along his arms and spine, and rowed, knife-sharp teeth designed for tearing through thick shell armor. Boisterous, loyal, energetic, and protective. Quick to judge whether a stranger is friendly or looking for a fight.

• Denki Kaminari (Electric Ray / Eel Merfolk): Sleek black and yellow patterned tail based on an electric ray. His skin generates bio-electric shocks when he feels startled or play-fights with the pod. Playful, easily distracted, expressive, and prone to reckless curiosity.

• Momo Yaoyorozu & Kyoka Jiro (Shallow Reef Duo): Momo sports vibrant red and gold beta-fish fins and flowing coral crests, while Jiro features sleek, dark-scaled traits with elongated, sensitive acoustic barbels that pick up vibrational frequencies in the water. Momo is cautious, regal, and methodical; Jiro is observant, low-key, and skeptical of surface noise.
