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.
Well, in a fanfiction where Harry's parents are alive, the entire emotional core of the story shifts. Harry's motivation wouldn't be driven by a sense of avenging his parents' death. Instead, it could be about protecting his family and the wizarding world together with them. His parents would introduce him to the wizarding world in a much more positive way. There would be no need for the Order of the Phoenix to rescue him from the Dursleys. And when it comes to the fight against Voldemort, the Potters as a family could use their combined magical powers and knowledge to outwit the Dark Lord. For example, James and Lily could teach Harry some advanced spells and defensive magic that they have mastered, which could give Harry an edge in the battles against Voldemort's Death Eaters.
Well, if Harry's parents were alive in fanfiction, it would completely change the whole dynamic. For one, Harry wouldn't have to live with the Dursleys. He'd grow up in a loving magical home, learning magic from his parents right from the start. His self - confidence would likely be much higher as he wouldn't have endured years of neglect and abuse. Also, the fight against Voldemort would be different. His parents would be right there beside him, using their skills and knowledge to fight the Dark Lord. Maybe they could have prevented some of the tragedies that occurred in the original story.
Well, for one, Harry would grow up in a loving family environment. He wouldn't have to live with the Dursleys. His magical education would likely start much earlier and be guided by his parents, especially James who was also a very talented wizard. His confidence and self - esteem would be much higher as he wouldn't have the emotional baggage of being an orphan.
If his parents were alive, the whole dynamic with Voldemort would be different. Instead of being an orphaned hero, Harry would be part of a family unit fighting against Voldemort. His parents could train him in advanced magic, and they might have connections and resources that could be used to combat Voldemort more effectively. Also, Harry might not have had the same emotional journey of self - discovery as he did in the original story, because he would have a more stable family environment.
In a fanfiction where Lily and James Potter are alive, the plot would be turned on its head. For starters, the Dursleys would never have come into the picture. Harry would have been raised in a loving magical family. This would mean he'd have access to all his magical knowledge and abilities from a young age without any suppression. Also, the war against Voldemort would have been fought very differently. Lily and James, being experienced and powerful wizards, would have led the charge. Their presence would have inspired a different kind of hope in the wizarding community. And think about Hogwarts - Harry would be going to school with his parents' support and influence, which could change how he interacts with his classmates and teachers.
The plot would change drastically. Harry would not be living with the Dursleys, so there would be no need for him to escape that horrible situation. Voldemort might have a harder time targeting him as his parents would be on high alert. There would be no letter - hunting drama. Also, his relationship with Snape would be different as his father was Snape's rival. His parents could have taught him some advanced magic from a young age, which would make him stand out at Hogwarts in a different way than in the original story.
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.
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.
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.
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.
If Harry is abandoned by his alive parents in fanfiction, it could completely change the story. For one, he might not grow up with the Dursleys. He could end up in a different magical or muggle family. This new family could either be very loving or have their own ulterior motives. His personality might also be different as he wouldn't have the same experiences of being an unwanted child in the Dursley's house. He could be more confident or perhaps more bitter depending on how his new family treated him.
