A great way would be to explore Rotom's relationship with a trainer. It could be about how a new trainer is initially scared of Rotom because of its spooky appearance but then learns to appreciate its intelligence and loyalty. They could go on a journey together, facing challenges and growing their bond, which is a positive and family - friendly way to feature Rotom in fanfiction.
No, it is completely inappropriate. Pokemon is a franchise aimed at a wide range of audiences including children. Creating such fanfiction goes against the family - friendly nature of the Pokemon brand and can be considered vulgar and unethical.
You can focus on its adventures. For example, write about Gardevoir joining a trainer in a difficult Pokemon tournament, facing powerful opponents and using its psychic abilities to overcome challenges.
You can focus on her growth as a character. For example, write about her journey to become a stronger trainer, how she overcomes her fears and insecurities related to Pokemon. This way, you stay true to the spirit of the Pokemon series which is about personal development and the bond between trainers and Pokemon.
You can focus on their adventures together. For example, write about them teaming up to defeat a new powerful enemy in the Sonic universe. This way, you can explore their different abilities and how they complement each other in combat.
One positive way is to write about their character growth. Sans could be learning to be more open and trusting, while Frisk might be growing in courage and wisdom. You could also write about them exploring the different areas of their world, like delving into the secrets of the Underground together in a platonic and exciting way.
One can also write about their redemption arcs. Imagine a story where they both start to question the pure - blood ideology they have been brought up with. This would be an appropriate and thought - provoking way to write fanfiction about them. It could involve their interactions with characters from other houses and how those experiences change them for the better.
You can focus on her battles and her growth as a warrior. For example, write about how she overcomes a new and powerful enemy using her unique magic skills. You could also write about her relationships with other guild members, like how she mentors the younger members and passes on her knowledge of combat and magic.
You can create new adventures for the characters. Maybe send Percy and his friends on a quest to a new and mysterious location within the 'Percy Jackson' universe. Write about their interactions, how they solve problems together, and the relationships that develop or change during the adventure. This way, it stays true to the essence of the original series while being creative.
You can focus on their friendship development. For example, write about how they support each other during their adventures at Hogwarts. Maybe Hermione helps Ron with his studies, and Ron stands up for Hermione when she faces prejudice from others. This way, you can explore their relationship in a positive and family - friendly way.
You can focus on her friendships, like her relationship with other members of the Order of the Phoenix. For example, writing about how she and Lupin support each other during difficult times in the fight against Voldemort.
