How does the story develop when Harry Potter gets the Infinity Stones in the fanfiction?

Well, he would probably become extremely powerful. He could use the Time Stone to go back and change certain events in the wizarding world, like preventing some of Voldemort's evil deeds. With the Power Stone, his magical abilities might be amplified to an unimaginable level, allowing him to defeat any dark wizard with ease.

The Infinity Stones could be linked to the Deathly Hallows. Maybe the Resurrection Stone has a connection to the Soul Stone. They could both have the power over life and death in different ways. And the other Infinity Stones could be related to the Elder Wand's power of domination and the Cloak of Invisibility's power to conceal, but on a much grander scale, if they were to be incorporated into the Harry Potter world.

When Harry is adopted by Poppy, it might lead to a change in the main plotlines. For example, Voldemort may not target Harry in the same way. Since Harry is under Poppy's care, he could be better protected. Poppy might train Harry in some unique forms of magic related to protection and healing. This could make Harry a more well - rounded wizard earlier in his life. And his relationships with other characters would also shift. Teachers might view him differently as he is now associated with Poppy, a respected figure at Hogwarts.

His character might become more confident, knowing he has the most powerful items in the universe at his disposal. He could be more decisive in his actions and less hesitant about taking risks.

First, give your OC a clear goal related to the Infinity Stones. For instance, if the character wants to collect all the Stones for a noble cause like saving their home planet. Then, think about their personality traits. Are they brave like Thor or more cunning like Loki? These traits will affect how they interact with others in the fanfiction.

The Infinity Stones could also change the magic system. In the Harry Potter universe, magic has certain rules and limitations. But with the introduction of the Infinity Stones, those rules could be bent or broken. For example, a character could use an Infinity Stone to perform magic without a wand, or to teleport across great distances without using apparition. This would create a whole new set of challenges and opportunities for the characters in the fanfiction.

One way could be that the Infinity Stones are hidden artifacts in the wizarding world. Maybe they were created by an ancient and extremely powerful wizard long ago, and their powers are so great that they are feared and thus hidden. For example, the Time Stone could be related to time - turners, but with much more powerful time - manipulating abilities.

In this type of fanfic, the Infinity Stones could have a very different effect in the Harry Potter universe. For example, the Time Stone could be used to reverse dark spells or resurrect fallen wizards. However, the Stones' power might also be limited by the magic rules of the wizarding world. The fanfic could delve into how the characters from both universes adapt to the presence of the Stones and how they use or misuse their power.

Hermione Granger would also be a likely candidate. Her thirst for knowledge and her extensive research in the library might lead her to discover ancient texts about the Infinity Stones. Then she would go on a mission to find them, using her intelligence and magical skills to track them down.

The plot could start with Harry unexpectedly coming across the Potter ring. Then, his encounter with Fleur might be by chance. As he wears the ring, he starts to notice changes in his magic. Fleur becomes interested in these changes and they start to explore what the ring means together.
