The plot could revolve around a prophecy in the wizarding world that foretells of a great threat from outside their realm, which turns out to be Thanos. Harry is the chosen one to stop him. At first, Harry is hesitant as he is not used to dealing with threats outside of the wizarding world. But as he sees the destruction Thanos is causing, he decides to act. He travels to different magical places in the wizarding world to gather powerful magical artifacts. With these artifacts, he is able to create a magical shield around the wizarding world to keep Thanos out. But Thanos manages to break through. In the final showdown, Harry uses a spell that combines the power of love (a powerful force in the Harry Potter world) and the unique magic of the wizarding world to defeat Thanos.
The plot could start with Thanos arriving in the wizarding world. Harry senses the great danger he poses. Harry would first try to understand Thanos' powers and motives. He might gather information from the Ministry of Magic's records or from ancient magical texts. Then, he would start to form a team of wizards and witches who are willing to fight. As the story progresses, they would engage in battles with Thanos and his minions. Harry would use his Patronus charm to protect his team from Thanos' dark energy, and he would gradually figure out a way to stop Thanos, perhaps by using a combination of powerful spells and the unique magical environment of the wizarding world.
One possible plot is that Thanos has already collected some of the Infinity Stones and his actions are starting to affect the wizarding world. Harry discovers that the magic in the wizarding world is somehow connected to the power of the Stones. He embarks on a journey to find a way to break this connection. Along the way, he meets various characters from both the Harry Potter universe and some new ones created for this fanfiction. These new characters could have knowledge about the Stones that Harry doesn't. In the end, Harry uses his Gryffindor courage and his magical skills to face Thanos directly and uses a self - created spell that targets the essence of Thanos' power, stopping him once and for all.
Maybe Harry Potter could stop Thanos with the help of his friends. Hermione's intelligence could come up with a plan. They could use time - turners to go back in time and prevent Thanos from getting the Infinity Stones in the first place. Ron could be there for moral support and also use his chess - playing skills to outwit Thanos in some strategic battles.
A Harry Potter who reverses Thanos would be a very interesting concept. Harry could use his ability to communicate with snakes (Parseltongue) to perhaps take control of some of Thanos' minions. His magical items like the Invisibility Cloak would give him an advantage in stealth. He might even use the Time - Turner to go back in time and prevent Thanos from getting the Infinity Stones in the first place. The Hogwarts environment could also be a factor, with its many secrets and magical defenses that could be used against Thanos.
Perhaps Harry teams up with some of his friends from Hogwarts. Ron could use his strategic thinking, and Hermione her vast knowledge of magic. Together, they create a magical trap for Ebony Maw. Harry, being the main hero, would be the one to lure Ebony Maw into the trap and then use a powerful combination of spells to stop him.
The Avengers would be shocked at first. They are not used to magic and seeing Harry Potter just swoop in and stop the Snap would be quite a surprise. But then they would be extremely grateful. They might start asking Harry a million questions about his magic and how he did it.
If Harry Potter stops holding back in fanfiction, he could become an even more powerful and assertive character. He might use his magic more freely and without hesitation, taking on greater challenges and enemies. This could lead to some really exciting and action - packed storylines, with Harry showing off his full potential.
Well, one possible plot could be that Harry discovers his true father is Thanos in a strange turn of events. He might struggle with the dark nature that could potentially be within him due to Thanos' lineage. Maybe he has to fight against the urge to use Thanos - like powers for evil while still trying to be the hero he was raised to be in the wizarding world.
There would be a clash of two very different power systems. Harry's magic might initially confuse Thanos. Thanos, on the other hand, with his brute strength and the Infinity Stones, would be a huge threat to Harry. Maybe Harry would try to find a magical way to neutralize the power of the Infinity Stones. For example, he could use a spell that disrupts magical or non - magical energy sources. It would be a battle of wits as well as power.
If we consider Harry Potter fighting Thanos in fanfiction, it's a clash of two very different universes. Harry has his wand and his knowledge of spells. He could try to transfigure Thanos into something harmless, but Thanos' willpower might resist such magic. The Time - Turner could also be a factor if Harry could use it to his advantage, perhaps going back in time to prevent Thanos from getting the Infinity Stones. But Thanos' brute force and his army could pose a great threat to Harry. It would be a battle that would depend on Harry's quick thinking and ability to adapt his magic to this new and powerful enemy.
A 'harry potter destroys thanos' fanfiction would be an epic clash of two very distinct fictional worlds. Harry, with his Gryffindor courage, would face Thanos fearlessly. He could use his Patronus charm to ward off Thanos' dark presence. His ability to apparate could give him an edge in dodging Thanos' attacks. The story could also involve the Ministry of Magic getting involved, perhaps trying to understand and deal with this new threat from a different universe. And the wands of the wizarding world would be a fascinating contrast to Thanos' gauntlet. It would be a story filled with action, adventure, and the exploration of how two such different worlds could interact in a battle scenario.
