One interesting plotline could be how the wizarding world deals with a new dark magic threat that was not fully resolved in the original series. It might involve new spells and magical creatures.
Another plotline could be that the Death Eaters who were thought to be defeated are actually working in secret again. But this time, they are using a new form of dark magic that combines with Muggle technology, and the main characters have to find a way to stop them while also keeping the wizarding world's secrecy.
Perhaps a plotline where the characters from 'Harry Potter' cross paths with the mystery - solving style of 'Case Closed'. So, they use their magic to solve non - magical mysteries in the Muggle world. For example, they might use magic to figure out who stole a valuable artifact from a Muggle museum.
Well, surely Harry Potter would be one of the main characters. He would be using his magic skills to get involved in the mystery - solving aspect.
One interesting aspect is the creativity it allows. With original characters (OCs) in the 'Case Closed' universe, fans can explore new storylines that the original series might not have covered. For example, creating an OC detective who has a unique approach to solving cases.
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.
In some fanfiction, a familiar might get lost in a different dimension. So, the main character has to go on a journey to find it. Along the way, they meet strange new creatures and learn new spells, which is really exciting. It also shows a different side of the bond between a wizard and their familiar.
There could also be a fanfiction where a member of the Sacred 28 discovers a long - lost family secret that has the potential to change the power dynamics among the pure - blood families. This secret could be related to a hidden magic or a forgotten alliance, and as they try to uncover more about it, they face opposition from other families who fear the change it might bring.
A common plotline is the characters' post - graduation plans. Some fanfictions might explore how Harry, Hermione, and Ron decide on their career paths. Maybe Harry is conflicted between becoming an Auror or a teacher at Hogwarts. Hermione could be considering further studies in ancient magic, and Ron might be thinking about joining his brothers in the joke shop business. This exploration of their future dreams and how they support each other during this transition period can be really engaging.
One possible plotline could be that Harry is wrongly expelled due to false accusations by a dark wizard who has infiltrated Hogwarts. Harry then has to prove his innocence while on the run from the Ministry. Another plotline might involve Harry being expelled because of a new, strict and unjust headmaster who has a vendetta against him. He could then start his own school for outcast witches and wizards.
Perhaps the snake is a transformed wizard who was cursed. This would lead to a plot where Harry has to find a way to break the curse. He might have to go on a quest to find rare ingredients for a potion. Along the way, he and the snake face various challenges, like dark wizards trying to stop them, and they form a strong friendship through their shared experiences.
