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.
Well, it's a very interesting concept. Harry Potter has his powerful magic, like the Patronus Charm and various spells from Hogwarts. However, Thanos is extremely strong with the Infinity Stones. But in a fanfiction, anything can happen. Maybe Harry could use his intelligence and magic skills to outwit Thanos. For example, he could use a powerful disarming spell to try and get the Infinity Stones from Thanos. It would be a very exciting battle to read about in a fanfiction.
There very well could be. Fanfiction writers often like to explore unusual crossovers. Since both Harry Potter and Thanos are extremely popular in their respective franchises, it's a ripe area for creative exploration. However, the quality and availability can vary greatly depending on the fanfiction platforms you search on.
In fanfiction, Harry Potter might be able to defeat Thanos by using his ability to understand and communicate with magical creatures. He could enlist the help of magical creatures like dragons or centaurs. The dragons could provide a powerful physical attack while the centaurs could use their archery skills and knowledge of magic. Harry would then use his own magic to disrupt Thanos' use of the Infinity Stones, for example, by creating magical interference. This combined force of different magical elements could potentially overpower Thanos.
He could use the power of love, which is a strong force in the Harry Potter universe. Love has been shown to defeat powerful dark magic, so it might be able to counter Thanos' power as well.
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.
Harry could win by using his intelligence. He might figure out a way to separate Thanos from the Infinity Stones. Without the stones, Thanos is still strong but more vulnerable. Harry could also use the magic of Hogwarts, like the protective spells around the school, to trap Thanos.
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.
In some fanfictions, there could be a situation where Thanos is actually related to an ancient dark magic in the Harry Potter universe. Harry has to figure out this connection and use it to his advantage. Maybe Thanos is after a powerful magical artifact in the wizarding world that he believes will enhance the power of the Infinity Stones. Harry and his friends then have to protect this artifact while also trying to defeat Thanos, which could lead to a series of epic battles and magical duels.
He would bring a whole new dimension of power. His magic could be used for offense, like powerful curses, and defense, such as protective enchantments. The Avengers might be initially skeptical, but once they see what he can do, they'd welcome him. For instance, he could create a magical shield around the team using a spell like 'Protego Maxima' which could withstand Thanos' attacks better than their normal shields.
