A fanfic with Harry's parents alive could have a plot where they discover a new threat to the wizarding world. Since they survived Voldemort's first attack, they are more vigilant. They raise Harry to be a strong wizard, teaching him both powerful spells and the values of the wizarding world. The story could involve them going on adventures together to find the source of this new threat. Along the way, Harry learns more about his family's history and his parents' experiences at Hogwarts. There would be a lot of family bonding and magical discoveries.
One great fanfic is 'The Potter Family Reunion'. It imagines how different Harry's life would be with his parents around. His parents, James and Lily, are actively involved in his upbringing, and he gets to grow up in a loving family environment. It also delves into how the wizarding world would change with the Potters alive, as they were important figures. There are interesting interactions between Harry and his parents, and it shows how they would have trained him in magic from a young age.
In a fanfiction where Harry's parents are alive, it could be that they were secretly protected by a powerful ancient magic. They were transported to a different magical realm. When they return, they bring with them new magical knowledge and spells. They help Harry become an even more powerful wizard. For example, they teach him how to combine different types of magic in unique ways. They also work to improve the relations between the wizarding world and other magical creatures.
Well, a lot of these fanfictions have the plot point of how the wizarding world politics change. In a fic like 'Potter's Influence', with his parents alive, the Potters become a powerful force in the wizarding world. They are able to sway opinions and policies. Also, the relationship between Harry and Draco can be very different. Harry, with the support of his parents, might not be as easily intimidated by Draco, and they could end up having a more complex relationship that isn't just pure rivalry.
The plot would change a great deal. For one, Harry wouldn't have to live with the Dursleys. He would grow up in a loving magical household. He'd be more confident and perhaps less of an underdog. His parents would be able to train him in magic from a young age, so he might be more advanced in his studies when he gets to Hogwarts. Also, the fight against Voldemort would be a family affair, with James and Lily Potter being key players in the battle against the Dark Lord.
A fanfic could revolve around a Hufflepuff whose parents are alive and own a magical business. The Hufflepuff student has to balance school life with helping their parents out during holidays. This could lead to all sorts of adventures as they meet different magical creatures and characters through the business. At the same time, they use the Hufflepuff traits of kindness and patience to deal with difficult customers and situations.
A typical plot element could be the conflict that arises from their presence. Some in the wizarding world might be suspicious or even afraid of the idea of the Potters being brought back to life. There could be a struggle between those who support Harry and his parents and those who think it's against the natural order of things. This can create a lot of drama and tension in the fanfic, making it an exciting read.
A potential plot development might be that Voldemort, upon hearing that the Potters are alive, would be enraged and try to attack them again. This would lead to a new series of battles and challenges for Harry and his parents. They would have to work together to fight off Voldemort and his followers. Also, Harry's parents could help him unlock new magical abilities or knowledge that he didn't have access to before because they are more experienced wizards.
One great fanfiction with Harry's parents alive is 'The Potter Family Returns'. It's a heartwarming story that shows how different Harry's life would be. His parents get to guide him through his Hogwarts years, and there are some really cute family moments, like family dinners in the Gryffindor common room. It also has some interesting new plotlines with the Marauders being involved in Harry's adventures.
Maybe Harry's parents are alive but they've been working undercover for a long time against a different dark force that is allied with Voldemort. When they come back into Harry's life, they bring with them a whole new set of problems and mysteries. For example, they might have made some dangerous pacts with other magical beings in order to gain information. Harry has to deal with the consequences of these pacts while also trying to keep his family together. Another plot twist could be that they are alive but time - traveling is involved. They've been stuck in a different time period and Harry has to figure out how to bring them back to the present, all while Voldemort is still a threat.
Well, Harry would likely be much more confident at Hogwarts. With his parents alive, he would grow up in a loving and magical home environment. This would translate into his school life. He would probably be more social and make friends more easily. He might also be less likely to get into dangerous situations with Voldemort. His parents could even be involved in the school in some way, like teaching a special class or being on the board of governors. This would give Harry a certain amount of privilege and protection that he didn't have in the original story.
