In St Edward's Ghost Stories, the nature of the ghosts varies. There are ghosts that exhibit malevolent behavior. The ghost of the disgraced teacher, for example, is said to bring misfortune to those who cross his path. He seems to hold a grudge from his past life. On the other hand, there are spirits that are more like lost entities. The ghost of the little boy in the dormitory corridor is often seen crying. He doesn't seem to mean any harm but is just lost in the afterlife, perhaps still looking for something or someone from his past.
In every world, there is a fairy, an apple fairy, a panda fairy, a cat fairy, a rabbit fairy.
The following is a novel that might meet the requirements:
" The Rabbit Demon's Journey to Wear Quickly "
The rabbit demon Lin Yaoyao had always thought that she was an ordinary rabbit until she transmigrated to a different world.
In the first world, Lin Yaoyao became an apple spirit in an ancient kingdom. She found that she had human-like characteristics such as intelligence, courage, and kindness. She helped the people of the kingdom solve many problems and finally won the recognition of the king and became an official in the palace.

One famous malevolent ghost story is 'The Bell Witch'. It's about a witch's spirit that haunted a family in Tennessee. The spirit would cause all sorts of chaos like making strange noises, physically harming family members, and even causing objects to move on their own.
Well, in malevolent Pokémon fanfic, the plot usually revolves around some sort of malevolence. It could be that a trainer has an evil plan involving Pokémon, like using them to take over the Pokémon world. The Pokémon in these fanfics may also have abnormal and more sinister behaviors compared to the normal ones. Maybe a Pikachu that doesn't like electricity but uses dark magic instead.
I'm not sure there are widely known 'malevolent Pokémon fanfic' specific writers in the mainstream sense. However, in the vast world of Pokémon fanfic communities, there might be some who are known for their darker takes. But it's hard to name one off the top of my head as it's a bit of a niche area.
