Mermaids with hair over their eyes are usually from deeper waters. The sea floor has almost no light, so deep sea mermaids (few of which have functional eyes) visiting the surface would be blinded by the sun.
To mermaids, covering their eyes with hair is similar to sunglasses.
Deep sea mermaids are also shy, accustomed to dark waters for hiding their monstrous appearances.
Freshwater Mermaid: Howdy y'all, I’d like you to meet my cousin. She’s a little shy :) 30ft Tall Deep Sea Mermaid with hair so long it turns the water black: ᴴᵉʷʷᵒ
[ context : the players are in a dungeon with a sentient stone lion ‘Leo’ blocking their only exit. they have to make him say his name without realising it. ]
Gnome Cleric: What’s your name?
Leo (DM): um– well, I can’t exactly… you see–
Half-Elf Sorcerer, *really* loudly: wHAT DO GYMNASTS WEAR????!!!
Leo (DM, completely baffled): uh, Leotards…?– oH FUCK!
*followed by laughter so intense, our half-orc warrior falls to the floor, tears streaming down their face*
tbh im kinda glad that a lot of the realistic pokemon in the detective pikachu trailer are high key teetering on the edge of uncanny valley because like.. these are fantasy creatures that sort of talk and shoot fucking electricity and vines and fire and psychic energy out their eyeballs, they SHOULD look weird and alien. psyduck is a pokemon defined by the fact that it is experiencing an unending headache that motherfucker better look like he has seen the rise and fall of civilization itself. mr mime is literally like three brain cells away from being straight up human the sight of one should make me uncomfortable.
basically what im saying is we have been spoon-fed woobified anime pokemon for too long. put the monster back in pocket monsters.
