I got motivated so here's a sketch of how I imagine merman park moondae in my pirate merman au :D (ill just stick to calling them merman now im getting tired of calling them fish men) hes sitting in keun sejin's boat and giving keun sejin a silent panic attack off screen ❤️
His tail is a bit dull at first due to OG park moondae being ostracised from other mermen so he's been just scraping by TT oh poor baby.
The tail regains its true golden sheen as both the bodyswapped Park Moondae and KSJ travel together ^^ idk if i translated well that he's a bit bony at this point. Just realised I forgot to render his body and neck gills. Oh well.
In my AU there would be all kinds of mermen. One thing to note though, they are BIG. as in long. Water snakes. I like thought of them being really long and strong.. Probably influenced by Rafayel's merman form lol.
For OG Park Moondae I imagine fins as being like betta fish tails.. Flowy and majestic. But his leans more towards being longer in length than spanning wide like in the ref photo. So a lot of his height is due to his tail.
In general a merman's main body is inherently vvv strong though, like a big snake. They're tough to cut through, and the strongest mermen are strong enough to strangle larger creatures with their tails alone. But to note, their gorgeous fins are on the delicate side, so it's a wonder that OG PMD managed to keep it wholly intact while surviving in the big blue alone.
Moondae, as he always is, quickly adapts to becoming a non-human pretty well. The not having feet is a bit nauseating sometimes, but he can appreciate the pros of having a tail. Of which is mainly for slapping KSJ when he's being annoying.
His teeth are sharper so at first when he meets the first human (KSJ) since he switched bodies, he talks a little slower to avoid biting off his own tongue by accident.
He mostly ate crabs and smaller fish when he realised he has to survive as a merman, but quickly upgrades to his signature yummy meals when he's able to get cooking amenities and actual seasoning from KSJ.
He's so sick of eating raw seafood that he doesn't care it's definitely suspicious how a merman knows how to cook. KSJ can make a pretty mean cocktail and every other alcoholic drink from his past experience as a crewmate, but his food is just okay.
KSJ has never eaten so well in his life, so he lets this matter slide.

I havent drawn in foreevr and never practised colouring + did this in like 20 mins. The tail gave me the most grief.. How do artists do that??
Only the power of Moondae has literally brought me out of my writing and drawing slump.
