Definitely Draco Malfoy. His family was on the wrong side of the war, and he has a lot of room for growth and redemption. Fanfiction could explore how he tries to make amends, perhaps by using his family's wealth and influence for good in the rebuilding of the wizarding world. He could also form unexpected friendships with former enemies.
Luna Lovegood is an interesting choice. She has such a unique perspective on the world, and in the post - war era, she could be involved in exploring the more hidden and strange aspects of the wizarding world that were overlooked during the war. Maybe she discovers new magical creatures or lost spells.
One of the most interesting characters to write about in post - war Harry Potter fanfiction is Teddy Lupin. He's a new generation, a half - werewolf orphan. His story could be about finding his place in the wizarding world, coming to terms with his unique heritage. And then there's George Weasley. After losing Fred, his post - war story could be about how he copes with grief while still running Weasley's Wizard Wheezes and maybe even expanding the business in new, innovative ways.
Definitely Snape. His complex character with his love for Lily and his role as a double agent has so much potential for exploration through memories. Harry himself is also interesting as his memories can uncover more about his family and his own growth. And Dumbledore, his past is full of mystery and his memories could reveal many secrets about his actions and motives.
One idea could be exploring how the wizarding world rebuilds its educational system at Hogwarts. For example, new classes could be introduced to teach about the importance of unity and the consequences of war. Another could be focusing on the relationships between the different houses, like a joint project where Gryffindors and Slytherins have to work together.
Definitely Ginny Weasley. She has her own growth story, and in fanfiction, it can be elaborated. She goes from being Harry's love interest to a strong, independent witch. Seamus Finnigan could also be a focus. He has a bit of a fiery personality, and fanfiction can show how he matures. And Fred and George Weasley. Their pranks and how they grow into more responsible but still fun - loving wizards can be great to write about.
Leonidas from '300' would be a great character to focus on. Imagine his reaction to the magic of the Harry Potter world. He's a fearless leader, and seeing him interact with wizards and magical creatures would be fascinating. He might see the magic as a new weapon or a strange form of sorcery that he has to either embrace or fight against.
Ron is often in the spotlight too. He might be struggling with finding his place in a post - war world. Maybe he's feeling overshadowed by Harry's hero status or trying to make a name for himself in the Ministry. Luna is another character that fanfictions like to focus on. Her unique perspective can bring a lot to the story, like helping to heal those who are still haunted by the war with her dreamy yet wise words.
One interesting plot could be Harry and Ginny renovating the Burrow together. They might discover hidden rooms or passages as they make changes, and it could be a really cute way to show their relationship growing in a post - war peaceful setting.
One great post - war Naruto Harry Potter fanfiction is 'The Crossover Chronicles'. It combines the magic of the Harry Potter world with the ninja skills of Naruto in a really interesting way. The characters from both universes interact in a post - war setting, which makes for some exciting plotlines.
Definitely Harry Potter and Kim Possible themselves. Harry has his whole wizarding world experience and his fight against dark magic, and Kim has her crime - fighting skills and high - tech gadgets. Their different worlds and abilities would create a really interesting dynamic as they try to understand each other and work together.
Harry Potter, of course. He has the most potential for character development in time travel scenarios. He can interact with his parents, for example, which would be a very emotional and interesting aspect. Then there's Sirius Black. He was a beloved character who died in the original series. In time travel fanfictions, he could be saved or have a different story. And Voldemort is also an interesting character to focus on. We could see how his rise to power might be affected if Harry were to travel back in time and interfere.
