One common theme is mystery. The spooky mansion setting lends itself well to mystery, like the Pokemon characters trying to figure out the secrets hidden within the mansion's walls. Another theme could be adventure as they explore the different rooms and face various challenges. And fear is also a theme, with the spooky atmosphere creating an environment where the characters might be scared of the unknown entities or events in the mansion.
Well, in addition to the obvious ghost - type Pokemon, Pikachu might also show up. Pikachu is one of the most popular Pokemon, and in a spooky mansion fanfiction, it could be the brave little Pokemon that stands up to the spooky elements. Then there's Charmander. It could be exploring the mansion and getting into all sorts of adventures. And Absol. Absol is often associated with bad omens, so it could be drawn to the spooky mansion and play an important role in the story.
I'm not entirely sure specifically what that fanfiction is about, but generally, in a scenario like 'pokemon scare at the litwick mansion', it could involve trainers taking their Pokémon into the mansion, which is known for its haunted - like atmosphere. The Pokémon might sense things that humans can't, like ghosts or other supernatural elements that are part of the Pokémon lore. Litwick, being a Ghost - type Pokémon, might play a central role in scaring the other Pokémon, perhaps by using its abilities to create an even spookier environment.
Often, you'll see the main character as a young and brave Pokemon trainer. They might be accompanied by their starter Pokemon, like Pikachu or Charmander. There could also be a spooky old caretaker of the mansion who has some mysterious knowledge about the place and its secrets.
Well, in a 'pokemon scare at litwick mansion fanfiction', it might involve trainers and their Pokémon entering the Litwick Mansion. Once inside, they could be frightened by the eerie atmosphere, strange noises, and the presence of Litwick and other ghost - type Pokémon. There could be a plot where they have to find a way to get out safely while dealing with all these scares.
Use descriptive language about the setting. For example, describe the creaking floorboards, the cold drafts that seem to have a life of their own, and the dim, flickering candlelight. Also, the characters' reactions can add to the spooky feel. If they are constantly on edge, jumping at every little sound, it will make the reader feel the same.
One idea could be exploring the backstory of the mansion itself. Maybe it was once a normal house before the spooky events started. Another could be focusing on a particular character's experience inside the mansion, like how they deal with the constant jumpscares. And a third idea might be to create a story where the characters find a way to break the curse of the mansion.
A brave and curious journalist could be a main character. They are always looking for a big story and think the mansion is their ticket to fame. Another could be a paranormal investigator who has been studying spooky places for years. And a young, adventurous kid who got lost and ended up at the mansion by accident.
I don't know for sure since I haven't read it. But it could be some well - known Pokémon trainers like Ash and his Pikachu. Maybe Pikachu gets really scared in the Litwick Mansion and Ash has to figure out how to comfort it.
One interesting plot could be that a group of Pokemon trainers enter the haunted mansion in search of a rare and powerful Pokemon. But once inside, they discover that the Pokemon they're looking for is actually a guardian of the mansion, protecting a dark secret. And they have to face various spooky challenges and ghost - type Pokemon along the way.
