Well, it could be about Harry Potter, in his younger days, stumbling upon a teen Teddy. Maybe they team up to face some sort of magical mystery in Hogwarts. For example, they might find a strange enchanted object that's causing chaos in the school and they have to figure out how to stop it.
There could also be other supporting characters. For instance, some of Harry's friends from Hogwarts like Ron and Hermione might make an appearance. They could be skeptical of Teddy at first or be involved in the adventures that Harry and Teddy go on. Also, Teddy's family or friends might be mentioned or even play a small part in the story, which could add more depth to his character.
At first, Severus would probably be very suspicious of Harry. After all, Harry is an unknown figure suddenly appearing. But Harry, being the friendly person he is, would try to break the ice. He might start by complimenting Severus on his potion - making skills, which Severus is already quite good at even as a young boy. Their interaction would be a bit tense initially, but as they start to understand each other more, they could become friends or at least allies.
There could also be some minor characters from the Marauders' era that might become more prominent. For example, Lily Evans, Harry's mother. Her relationship with James and how she might interact with Harry in this strange time - traveling or spirit - meeting scenario could be really interesting. And then there are the Hogwarts professors from both eras that could be involved, like Professor McGonagall, who could either be a guiding force or be a bit skeptical of Harry's new interactions.
Perhaps a plotline where the Marauders' spirits or echoes are awakened in Harry's time at Hogwarts. They start guiding him in his fight against Voldemort. They teach him spells and strategies that they used during their own battles against the Dark Arts. This would give Harry an edge and also create some really heartwarming and funny interactions as he tries to keep their presence a secret from his friends.
One interesting Harry Potter Teddy fanfiction could be about Teddy's adventures at Hogwarts. He might discover new spells or form unique friendships, just like Harry did. Another could focus on Teddy's relationship with his godfather Harry, showing how Harry's guidance shapes Teddy's life. And there could also be a fanfiction where Teddy uses his shape - shifting abilities in a creative way to solve a mystery at Hogwarts.
One common theme is friendship. Just like in the original Harry Potter series, the teddy bear often forms strong bonds with the characters. For example, it might become best friends with Ron or Neville.
One possible plot could be that Harry, through some time - traveling magic, meets young Severus. Harry, knowing Severus' future, tries to befriend him and change his path. He could introduce Severus to different ways of using magic that are less dark - oriented, which might change Severus' perception of magic and his future relationships in Hogwarts.
Some popular themes include friendship with the BTS members. For example, a story where the teen girl becomes friends with them and they go on adventures together. Another theme is self - discovery. In the fanfiction, the girl might find her true self through her interactions with BTS. Also, the theme of achieving dreams is common. She could be inspired by BTS to pursue her own dreams, like singing or dancing.
Reading BTS fanfiction can be beneficial as it can improve their reading skills. Since they are likely to be very interested in the content, they'll be more motivated to read. It also allows them to use their imagination more. They can picture themselves in the stories with BTS.
