Oooo for mermay? Hmm let’s see. (If you can’t tell I’ve been reading too many teratophilia fics hahaha)

• I think Hanzo falls into the category of one of the more monstrous looking mermaids or mermen. He’d have a tail reminiscent of a leafy sea dragon, long and coiling and moving almost like silk underwater. His scales are a mix of different blues, mottled and ever so slightly shiny as to camouflage into his surroundings. 
• Hanzo has a fairly humanoid torso, with dark and light blue scales creeping up his sides and back, with fins lining his spine. His talons or clawed hands are also scaly and sharp, almost like keratin, and they are of a darker colouration than the rest of his body. In place of his tattoos, there would be gold and silver markings along his left arm and pectoral, markers of a particularly attractive male among the merpeople. 
• I’d also say mer!Hanzo is a predator and thus would have sharp teeth not unlike that of a shark. 
• There would be gills along his ribs and dragon-like fins in place of his ears, and his hair and facial features would be the only part of him that appears human. His eyes, molten gold and slitted, allow him to see through the darkness of the water clearly and has limited heat vision in complete darkness. Dark blue, light blue, and beige scales would cover his jawline and up his cheeks, giving him an ethereal appearance should he ever stick his head above the water.
• But enough about his physical appearance, what about his temperament? Well, Mer!Hanzo doesn’t differ much from his human counterpart. He’s fairly anti-social and prefers to live on his own away from other merpeople. Sometimes Genji visits, but it’s hard to find Hanzo among the weedy reef that makes up his home. He travels but not very far, preferring to stick to familiar waters where he’s certain there are no other merpeople. 
• In the same fashion, he dislikes humans and will actively avoid them if he can. The only time he will confront or attack humans is when they are coming too close to his den, or if they are whaling or fishing for sharks. He considers the aquatic life in his territory his subjects and will protect them if necessary. Divers who are just looking for shells or exploring, however, he will leave alone.
• By the way, he has a lousy singing voice, so no one will ever mistake him for a siren of some sort. He does have a very mesmerising way of reciting poetry, however.
• I’d say the only ways you can meet Hanzo are through diving, or if you’re a frequent visitor in his territory and you get swallowed up by the ocean for some reason. If you’re just some random person who just so happens to be drowning in his territory, he’s more than likely to let you drown so he can have some peace and quiet. 
• Once familiar with you, Hanzo gets more than a little attached. He’ll bring you offerings in the form of shells or clams or bits of treasure that he finds. He can’t beach himself or travel on land due to his tail, and resorts to tapping the hull of your boat until you come down to meet him. If you bring him little presents in return, he’ll likely look at you with starry eyes and thank you in a quiet, awed tone. 
• Like most sea dragons, Hanzo bears a slit where a female’s ovipositor would deposit her eggs for him to incubate. But unlike most sea dragons, he has a penis that he uses to seed the female first. It emerges from above his slit, and is as colourful as he is. It has a pointy head and a thick base, riddled with ridges and prongs to help stimulate all of your sweet spots. It’s incredibly sensitive, and most times if you get your mouth around him, he spills almost immediately. Same with his slit, though it’s slightly less sensitive than his cock. 
• Unlike sea dragons, Hanzo’s kind mates for life. Once he mates you, he’ll probably follow you wherever you go. He can’t go up to land, but that’s okay, because you’re likely to have a job that takes you out to sea often, and he can meet you there. He’s very happy to accommodate you when he can, begging you for attention when you can spare it. He’ll guard your boat and chase away anyone and anything that comes near. Those talons are deadly and he’ll show you just how deadly they are. He has a limited amount of magic from his ancestry, which he uses to protect your boat during stormy weather.
