The Infinity Stones were created by a complex interplay of cosmic powers and entities. Their creation wasn't the work of a single being but rather a result of various cosmic events and forces coming together. Different comic arcs might offer slightly different explanations or emphasize different aspects of their origin.
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.
It could be about the Mad Titan Thanos in his early days, before his full - blown obsession with the Infinity Stones. We might see how he first learned about the Stones and what led him on the path to collecting them all. Another possibility is that it could feature the Asgardians, as they had knowledge of at least some of the Stones. We could see Odin's early encounters with the Stones and how he dealt with the power they held.
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.
I have no idea. Figuring out the creator of the initial story with the infinity stones is tough. It might be a hidden gem in the world of storytelling that's yet to be widely discovered.
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.
