One interesting plotline could be a character having an unexpected child with a former love interest. For example, if Draco Malfoy had a child with a Muggle - born witch he had a brief relationship with during his post - Hogwarts years. This would create a lot of drama as it goes against his family's pure - blood values and would cause a stir in the wizarding world.
The 'baby mama drama' can create new plot twists. It can change the way characters interact and develop. For instance, if Ginny Weasley had a child with someone unexpected and there was drama around it, it would affect her relationship with her family and friends. It could also lead to new alliances or rivalries within the wizarding community. It can make the fanfiction more complex and engaging as it goes beyond the typical magical battles and adventures.
One interesting plotline could be Harry showing early signs of magic that the Dursleys try to suppress. For example, he might accidentally make Dudley's toys float when he's angry or frustrated.
One possible plotline could be that the kidnappers are actually working for a powerful dark wizard who wants to raise Harry to be his minion. Another could be that the kidnappers take Harry to a far - off land where he grows up without knowledge of the wizarding world until he discovers his true identity in a very unexpected way.
Well, a common plotline is that Snape is initially reluctant to be around baby Harry due to his hatred for James. But as he spends time with the baby, he starts to see Lily in Harry. He might start to protect Harry not just for Lily's sake, but also because he begins to care for the child himself. Some fanfictions also explore how Snape's interactions with baby Harry might change the future events in the wizarding world, like how it could affect Harry's relationship with Snape when he grows up.
Another plotline could involve Severus struggling with his own emotions towards Harry. On one hand, he has his long - held grudges against James Potter, Harry's father. But on the other hand, he has a sense of duty to protect Harry. This internal conflict could drive many of the story's developments, like how he interacts with Harry on a daily basis, whether he is strict or lenient, and how he deals with Harry's questions about his parents.
One interesting plotline could be Severus taking on a fatherly role to protect Harry from the dark forces at Hogwarts. He might use his knowledge of potions and magic to keep Harry safe.
Another plotline could involve the baby having some sort of special power. This would add an element of mystery and adventure as they try to protect the baby from those who might want to use its power for evil.
Well, some might involve magical creatures with furry characteristics in new adventures at Hogwarts. For example, a werewolf character could have a unique story arc that intersects with the main Harry Potter plot. Maybe they are trying to find a cure or dealing with the prejudice within the wizarding world in a different way than what's in the original books.
One possible plotline could be a comical take on baby Harry's magical mishaps. Maybe he accidentally makes his diapers levitate or turns his crib into a mini Hogwarts. Another could be about how the other characters like Hagrid or Dumbledore interact with baby Harry in this unique situation, perhaps trying to figure out how to handle his early magical outbursts while he's still in diapers.
Perhaps a plotline where the ogre has some sort of special power that the wizards in Harry Potter are interested in. This could lead to a whole series of events where they try to either control or cooperate with the ogre.
