Another way an oc can interact with the Infinity Stones is by using their own unique abilities or skills to harness the Stones' power. For instance, if an oc has the ability to manipulate energy, they could use that to better control the power of the Infinity Stones. They might also be able to create devices or spells that enhance their connection to the Stones, allowing them to use the Stones' power more effectively in different situations.
One way could be through a powerful dark wizard's experiment. Maybe a wizard, seeking ultimate power, discovers a way to bring the Infinity Stones into the magical world. They could be hidden as powerful magical artifacts, and their powers might be harnessed in a way similar to how wizards use magic. For example, the Time Stone could be used to manipulate time within the wizarding world, perhaps to reverse a tragic event or to gain an advantage in a battle.
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.
A Jedi with all the Infinity Stones would be an extremely powerful force. They could use the Time Stone to foresee any threats to the galaxy and prevent them before they happen. With the Mind Stone, they could potentially influence the minds of Sith Lords to turn them away from the dark side.
If Spider Man had all the Infinity Stones, he would be extremely powerful. He could use the Time Stone to reverse bad events or prevent disasters. The Power Stone might enhance his physical strength to an unimaginable level, making him even more capable in combat against powerful foes. And with the Mind Stone, he could perhaps gain greater wisdom and understanding of his enemies' plans.
The Power Stone, being a source of immense destructive power, could be a game - changer in Star Wars. It could potentially destroy entire star systems with a single blast. This would force the various factions in Star Wars, like the Galactic Empire or the Rebel Alliance, to either try to obtain it for themselves to gain an upper hand, or to prevent their enemies from getting it. It would introduce a whole new level of threat and power struggle that goes beyond the typical lightsaber battles and political intrigue.
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.
