In some fanfictions, Harry's mastery of snakes might lead to him having a new role in the fight against Voldemort. Instead of just being the Boy Who Lived, he could use his snake - related abilities to outwit Voldemort in a completely different way. Maybe he could communicate with Nagini in a way that no one expected and use that to their advantage.
Perhaps a plot where Harry uses his mastery of snakes to uncover ancient secrets in Hogwarts. He could find hidden passages or long - forgotten magic related to snakes that no one else knew about. This would not only add to his own power but also change the dynamics of the wizarding world as they know it.
One interesting plotline could be that Harry discovers an ancient prophecy related to snake communication. He has to figure out what it means and how it ties into the overall battle against Voldemort. Another could be that he uses his snake - communication to befriend a powerful and magical snake that helps him in his adventures. Maybe it guards a secret passage or gives him clues to find hidden magical artifacts.
Well, perhaps in this fanfiction, Harry's snake -raising has given him some special powers related to serpents. For example, he could have the ability to move as silently as a snake or even use some snake -like magic that others don't possess. Also, the story could explore how his relationship with the snakes affects his relationships with his human friends. Maybe at first they're a bit put off, but later come to understand and accept this part of him.
A frequent plotline is that Harry's snake - talking ability gets him into trouble with other students. They might bully him or be jealous of his unique power. There are also stories where the snakes themselves play a more active role. For instance, a snake might become Harry's guide or protector, leading him to places he wouldn't otherwise go or protecting him from danger. This can create a really interesting dynamic in the fanfiction.
A great plotline in such fanfiction could be a Potion Master being framed for creating a harmful potion. The real culprit might be someone trying to discredit the Potion Master for personal gain, like a rival for a teaching position at Hogwarts. The Potion Master then has to prove their innocence while also dealing with the chaos that the false accusation has caused in the wizarding community. They might have to enlist the help of their students or former colleagues to clear their name.
In some fanfictions, Harry's time - mastery allows him to interact with past versions of himself. This can create really complex and mind - bending scenarios. He could use these interactions to gain wisdom from his past experiences more directly, or to give his past self crucial information that would help him in his battles against Voldemort. For instance, he might tell his younger self about a hidden weakness of a particular Death Eater that he discovers in the future.
In some fanfictions, Harry's mastery of illusions might lead to him being able to enter people's dreams and manipulate them. He could use this power to either help his friends overcome their fears or to gather information from the enemy. However, he would also have to face the moral implications of such actions.
One interesting plotline could be Harry mastering new and powerful magic that was not explored in the original books. For example, he might discover a long - lost spellcasting technique. Another could be his relationships with other characters evolving in different ways, like a deeper friendship with Neville or a different kind of mentorship with McGonagall.
One interesting plotline could be Harry fully exploring and mastering the powers that come with being the Master of Death. He might use these powers to reshape the wizarding world in ways that were not possible before, like eradicating dark magic at its source.
There might be a fanfiction where a magical snake is a guardian of an ancient Hogwarts secret. This snake could communicate with Harry in Parseltongue and guide him to discover something that has been long forgotten in the castle. It could be related to a powerful spell or a hidden chamber that holds the key to defeating a new dark force threatening the wizarding world.
One possible plotline could be Harry exploring the full extent of his newfound power as the Master of Death. He might use it to bring back loved ones in a way that doesn't disrupt the balance of the wizarding world. Another could be that he faces new and more powerful enemies who are threatened by his status.
