He might become extremely powerful. The Infinity Stones have the power to manipulate reality, time, space and more. Harry could use it to defeat Voldemort in a much easier way. For example, with the Time Stone, he could go back in time to prevent certain events that led to Voldemort's rise or stop him from ever being born.
It's a very interesting concept. If Harry Potter got an Infinity Stone in fanfic, his relationships with other characters would also be affected. His friends might be in awe of his new power, but also a bit afraid. Hermione, for instance, would probably be very cautious about how he uses it. And the Ministry of Magic would surely view him as a huge threat, leading to a whole new set of conflicts. He would have to learn to control this new power while still staying true to his values.
If Harry Potter got the Space Stone, he could use it to instantly transport himself and his friends to different locations. This would be a great advantage in their fight against Voldemort, as they could quickly escape dangerous situations or reach important places without being detected. For example, they could suddenly appear in the Death Eaters' lair to gather intelligence.
Well, in a fanfiction scenario where Harry Potter finds an Infinity Stone, it would completely disrupt the balance of power in the wizarding world. Imagine if he got the Mind Stone. He could use it to read the minds of his enemies, uncover their plans way in advance. It would also likely attract a lot of unwanted attention from other powerful beings, both in the wizarding world and perhaps from the Marvel universe if there was some sort of crossover in the fanfic. He would have to be very careful not to let the power corrupt him, just like what could have happened to many characters in the original Harry Potter series who were tempted by dark magic.
He would probably become extremely powerful. He could use the Infinity Stones' powers to defeat Voldemort in an instant. For example, the Power Stone could enhance his magic to an unimaginable level, and the Time Stone might allow him to go back and prevent bad things from happening in the wizarding world.
Well, he'd probably become super powerful. The symbiote could enhance his magic skills and give him some cool physical abilities like super strength and agility. Maybe he could use it to fight the Dark Arts in a whole new way.
Yes, there are likely some fanfics out there with this concept. The 'Harry Potter' universe and the idea of the Infinity Stones from the Marvel universe are both very popular, so some creative fans might combine them in their fan - created stories.
In the 'Harry Potter has the Infinity Stones' fanfic, the whole wizarding world would be changed. Harry might use the Reality Stone to create illusions that are so real they could deceive even the most powerful wizards. With the Mind Stone, he could perhaps read the minds of his enemies and gain crucial information for his battles against the dark forces. And the Space Stone could help him teleport around the wizarding world, giving him an edge in both escape and surprise attacks.
It could bring back powerful wizards. For example, if a wizard like Merlin was resurrected using the power of the Infinity Stones, it would change the power balance in the wizarding world. He could have knowledge and magic far beyond what is currently known, and his return could either help in the fight against evil or cause new problems if his views are different from the modern wizards.
In a Harry Potter fanfic with the Infinity Stones, the Stones could interact with the existing magical artifacts in interesting ways. The Elder Wand, for example, might have some sort of connection or reaction with the Infinity Stones. Wizards and witches who were already powerful, like Dumbledore, would have to figure out how to deal with these new and extremely powerful elements in their world. It could also lead to new forms of magic being discovered as the Stones' powers merge with the magic already present in the Harry Potter universe.
Let's say Hermione found an Infinity Stone. She would immediately start researching it. She would scour the Hogwarts library and use all her knowledge of magic. She might try to find a way to control it or at least contain its power. She could also consider the ethical implications of such a powerful object. Would it be like a Horcrux? Should it be destroyed? These are the kinds of questions she would ask herself.
One way they could interact is through a magical accident. Maybe a wizard accidentally casts a spell near an Infinity Stone and it creates a rift between the two universes. Characters like Harry Potter could then be drawn into the Marvel universe. They might be initially confused by the high - tech and different power systems in the Marvel world. For example, the Infinity Stones' power to control reality, time, etc. would be a new concept to Harry who is used to magic like spells and potions.
