Yona from The Legend of Zelda Tears of the Kingdom. I did not have much to work with on this one, so please keep in mind that it might not generate properly when it comes to her accessories.
Positive Prompts: Yona
female fish, green body, jewelry, horns, yellow eyes, necklace, neckwear
Extra: sharp teeth
Her necklace and jewelry is almost never accurate, but you can always just put "necklace," "neckwear," and "jewelry" in the negative prompt if it bothers you. Other than that, it does a good job generating her accurately. I think her accessories is just a bit too complex for the AI to get down right lol.
