Froslass

Froslass is particularly creepy for two reasons. Its origin story is extremely sad, as it is said to represent the manifested anger of a deceased woman. On the other hand, it enjoys taking revenge on men, whom it uses as decorative objects or, as the entry in Pokémon Moon reveals, eats:
It is said that the soul of a woman who perished in the mountains has entered a hanging icicle. It prefers to feast on men’s souls.
Therefore, those who encounter this Pokémon as a woman have a higher chance of surviving the encounter. However, according to the Pokédex in Pokémon Sun, Froslass generally freezes humans and Pokémon with icy air to exhibit them in its lair. Living beautifully with Froslass.
