harry potter creates a third side fanfiction

No. Harry Potter is a fictional character within the Harry Potter series. He doesn't have the ability to create fanfiction in the real sense. Fanfiction is created by fans of the series in the Muggle world, using their creativity to explore different scenarios or relationships that may not be fully explored in the original books. So, it's not possible for Harry Potter himself to create such fanfiction.

Well, it could be about Harry creating a secret society within Hogwarts that combines the best of both Gryffindor and Slytherin traits. This society could focus on using magic in new and unorthodox ways to solve problems that the regular school curriculum doesn't cover. Maybe they work on protecting magical creatures in a more proactive way, like creating magical habitats outside of the Forbidden Forest.

One idea could be that Harry creates a school for magical creatures. He realizes that there are so many unique and often misunderstood creatures in the wizarding world, and he wants to give them a place to learn and grow. This school could teach them how to interact with wizards in a positive way, as well as develop their own magical abilities.

Dumbledore could be a significant presence, even if he's no longer alive in the original timeline. His wisdom and knowledge could be passed on in some magical way, like through a magical diary or a portrait that has special powers. And then there could be some characters from the dark side who are trying to redeem themselves, such as a former Death Eater who sees the error of their ways and joins Harry's new movement in the fanfiction.

One idea could be that Harry discovers an ancient spell book in the Room of Requirement that has the incantations for creating a magic railgun. He might use it to defend Hogwarts against a new, powerful dark force that is immune to traditional magic spells.

In this fanfiction, Harry might also include some of the Hogwarts ghosts in his army. After all, they have a long - standing relationship with the school. Peeves, for example, could be a wild card in the army. He can cause chaos among the enemies. And some of the older students who have a strong sense of justice, like Cedric Diggory's friends, could also be part of it.

The plot could start with Harry finding an ancient Jedi artifact during one of his adventures. This leads him to become curious about lightsabers. He then uses his magic knowledge to try and replicate it. Along the way, he might face opposition from some in the wizarding world who think it's too dangerous or against wizarding traditions. But Harry, being the hero he is, persists. Eventually, he creates a lightsaber and uses it to defeat a new, powerful dark wizard who has emerged, using both his wizarding skills and his new lightsaber skills.

In a fanfiction where Harry Potter creates a virus, perhaps it's a virus that affects magic itself. The virus could spread through spells and start to corrupt the very essence of magic. Harry, realizing the severity, might then have to team up with his old friends like Hermione and Ron. They would search for ancient magic or rare potions to counteract the virus before it destroys the entire magical ecosystem.

In a 'Harry Potter creates a shelter' fanfiction, perhaps Harry uses his magic to create a shelter in the Forbidden Forest. He might use spells like Protego Totalum to make it safe from dark creatures. It could be a place where he hides his friends during a dangerous time at Hogwarts, like when Voldemort's forces are on the prowl.

One possible plot could be that Harry, after defeating Voldemort, decides to create a kingdom where magic and non - magic folk can live together in harmony. He uses his knowledge of magic and the respect he has gained to build a new society with its own set of laws and governance that are fair to all. For example, he could create schools that teach both magic and Muggle subjects to promote understanding between the two worlds.
