One possible plotline could be Harry Potter taking on the corrupt Ministry of Magic to ensure fair treatment for all magical beings. Maybe he discovers some dark secrets within the Ministry and decides to expose them to bring about justice.
In some versions of this fanfiction, Harry Potter could be on a quest to find out the truth behind some unjust imprisonments in Azkaban. He might believe that some of the prisoners were wrongly accused and use his skills and resources to prove their innocence and reform the wizarding justice system which has been marred by fear and prejudice.
One possible plotline could be Harry using life debts to form powerful alliances. For example, he might call in a life debt from a powerful wizard who then helps him in a battle against dark forces. Another could be that Harry uses a life debt to gain access to some long - hidden knowledge or a secret place.
Perhaps Harry finds out that the Dementors were being misused by the Ministry of Magic. He then decides to demand justice for all those who were wrongly affected by the Dementors. He could fight to change the way Dementors are used in the wizarding world, or even find a way to rehabilitate them if possible. Or it could be that Harry uncovers a conspiracy within the Order of Phoenix where some members were acting for their own self - interests rather than for the greater good. He then has to hold those members accountable and restore the integrity of the Order.
One possible plotline could be that Harry, feeling a lack of maternal love in his life, subconsciously starts seeing McGonagall as a mother figure. This could lead to him seeking her advice more often, not just about school matters but also about his personal struggles. For example, he might go to her when he's having nightmares about Voldemort instead of just his friends. Another plotline could be McGonagall initially being taken aback by Harry's behavior but then gradually warming up to the idea. She could start to protect Harry even more fiercely, like a mother bear with her cub.
Well, obviously Harry Potter himself would be the central character. He has always been a fighter for what's right in the original series, so it makes sense for him to be the main character in a fanfiction about justice.
Well, one interesting scenario could be Harry Potter calling the Aurors to deal with a group of dark wizards causing chaos in Diagon Alley. The Aurors arrive swiftly, wands at the ready, and engage in a spectacular magical battle against the dark forces. This would show the Aurors' skills and teamwork.
Some fanfictions might explore justice for the 'mudbloods' who face discrimination. It could show a world where the pure - blood supremacist ideas are quickly quashed and those who have been bullied or looked down upon due to their non - pure - blood status get justice. For example, students like Hermione are no longer taunted and instead are respected from the start.
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.
