The Water Hag (by WyfuDaddi)

Supernatural Ugliness; in their true forms most hags are supernaturally ugly, Water Hags are no exception.
Peak Human Beauty/Supernatural; when in disguise they may be beautiful maidens or the idealized form of whoever they seek to trick

Their complexion was like that of a rotting fish: pallid yellow skin with patches of green, slimy scales and bony protrusions. Their piscine eyes were similarly devoid of life with deep, black pupils surrounded by red. Hags were universally hideous beings, but even by the unbelievably low standards applied to their race, sea hags were abysmally grotesque. Despite their penchant for devouring their victims they had an emaciated appearance, although they could be of varying height and big-boned as opposed to scraggly

repulsive and wretched of hags and were prideful in their gruesome appearance. The wicked fey lived near or within large bodies of water and the unfortunate souls that set eyes on them were often feasted on shortly after.
